General Information
Safety Information The Televic Wired Confidea Digital Conference &
Interpretation System is state of the art and has been
designed to meet quality. Nevertheless, the individual
components of the conference system can cause danger
for persons and material assets if
• the conference system is not used as intended,
• the conference system is set up by personnel not
familiar with the safety regulations,
• the conference system is converted or altered
incorrectly,
• the safety instructions are not observed.

Wired Confidea – the digital conference & Interpretation system
Overview If you require high-quality conference and interpretation
equipment to support the communication process, then
the Wired Confidea Digital Conference & Interpretation
System is the solution to your problem. The new Wired
Confidea Digital Conference & Interpretation System
exploits all the advantages of digital communications
technology and offers its users a series of important
features:
• decentralized, clear sound reproduction,
• a full Digital System,
• easy installation and total control,
• functional and extremely easy to operate delegate
units,
• audience interaction,
• advanced functionality,
• the possibility to be combined with an infrared
Language Distribution System.
The Wired Confidea Digital Conference &
Interpretation System is the perfect choice for both
small seminars and large international conferences.
An important feature of the Wired Confidea Digital
Conference & Interpretation System is its modular
design. Even when you change from a configuration for
small conferences to a larger configuration, you can
easily add additional conference units and a software
control program. Whatever the circumstances may be,
the system can:
10
• quickly be set up, since all conference units are
connected in series,
• easily be configured for any kind of room and any
kind of participants.
11
The components of the Wired Confidea Conference & Interpretation System
A Wired Confidea Digital Conference & Interpretation
System basic setup consists of the following
components:
• delegate units,
• interpreter units,
• a central unit,
• system cables,
• and if required, the software control suite for the
conference system.
12
The delegate units
The delegate units feature a built-in loudspeaker,
allowing the participant to directly hear all audio
information, e.g. speeches, presentations or any other
audio material. This loudspeaker system ensures
excellent sound quality at a comfortable volume
throughout the entire conference room.
The delegate unit’s electret microphone transmits every
word in excellent audio quality over the system. The red
signal ring on the microphone serves as an indicator of
who is currently occupying the floor (when the red light
is on).
In configurations with voting units, the conference
participants can participate in voting sessions.
The delegate units can range from the most basic units
to delegate units intended for a chairman with options
like voting, interpreter channel selection and an Oled
display. All the different delegate units will be
presented in the next chapter.
The units are connected in series. One cable string can
comprise up to 20 conference units. The 6 ports at the
back of the central unit can each connect a string of
delegate units. Up to 120 delegate units can thus be
connected to one central unit. And up to 1024 delegate
units can be set up through coupled central units.
All the different delegate units will be presented in the
next chapter.
Use of TCS2500 delegate units and flushmount combipanels in combination with Wired Confidea units
The TCS2500 delegate/chairman units and flushmount
combipanels can be used with Confidea CU .
Remark : It is NOT allowed to connect devices with
automatic input/output detection (like Wired Confidea
delegate units) and other devices without automatic
input/output detection ( like TCS2500 delegate units or
flushmount combipanels ) in the same branche !
13
The units are connected in series. One cable string can
comprise up to 20 conference units. The 6 ports at the
back of the central unit can each connect a string of
delegate units. Up to 120 delegate units can thus be
connected to one central unit. And up to 1024 delegate
units can be set up through coupled central units.
The interpreter unit
The interpreter unit has a similar design as a delegate
unit. Next to the quality microphone and the headphone
output it has three knobs for adjusting the volume,
treble and bass levels of the incoming speech.
The badge can contain all relevant information for each
interpreter so that each interpreter can transfer his
settings to a new interpreter unit.
An extended amount of functionality is made available
on the interpreter unit by the easy to use interface knobs
and buttons and the LCD display. Every aspect of this
functionality will be explained in the next chapter.
14
The CONFIDEA CU
The CONFIDEA CU is the core of the Wired Confidea
Digital Conference & Interpretation System and, at the
same time, serves as an interface for additional audio
systems.
During the conference, the central unit will manage the
speech of the delegate units and the interpreter units.
Via the central unit’s operating menu, the configuration
of the conference system can be altered to satisfy the
needs of the conference room and its users.
On the central unit, you can choose between 10
different conference modes, each with its own specific
characteristics. However, some of these operating
modes are only relevant in a system with the PC control
software.
The central unit manages the microphones, allows the
operating mode to be set, activates the microphone units
and manages the request-to-speak list.
The central unit has a built-in power supply unit for
powering up to 120 delegate and/or interpreter units and
is therefore more than sufficient to set up a basic
conference system. For larger conference systems,
additional central units can be interconnected.
The system cables
Power supply of the conference and interpreter units is
via the system cables which also transmit the digital
audio and status information.

15
The software control suite (optional)
A conference manager can control the entire conference
via a PC if he uses the optional software control suite.
The software control suite provides several extra
functions, next to the functionality provided by the
central unit:
• Additional functions for microphone management:
the conference manager can easily monitor which
delegates have made a request to speak, which
delegates are currently speaking, activate certain
microphones, etc. Two possibilities to manage the
microphones are supplied: the first is a schematic
view of the room and the delegates; the second is
through a list of names (nominative view).
• Display of voting results as diagrams: the results of
a voting can be represented graphically and can, for
example, be displayed in the conference room by
using a projector. Voting in combination with badge
verification is also possible.
• Interpreter management: the conference manager
can configure each desk in each booth.
Configuration includes assignment of languages to
interpreter units (both for the A and B channel),
operation modes, etc.
• Delegate database: the delegate database allows the
conference manager to specify delegate information.
This information can then be displayed in the
nominative and the schematic view of the
microphone management screens. It is also possible
to use the information contained on the badges.
• Multiple Chairmen units: the conference manager
can assign multiple chairmen units.
The technology used
Both the control and sound transmission of the Wired
Confidea Digital Conference & Interpretation System
are digital, resulting in excellent quality. The language
channels are transmitted over a 16 kHz bandwidth at a
16-bit resolution.
The delegate units are connected to each other and to
the central unit by means of system cables. The system
uses one digital speaker channel and a simultaneous
translation of 4/8/28 channels.
16
The components of the Wired Confidea Conference & Interpretation System
The components The components described on the following pages are
available for the Wired Confidea Digital Conference &
Interpretation System. Which of these components you
require depends on the desired size of the Wired
Confidea Digital Conference & Interpretation System.
The Wired Confidea ( Confidea-L) delegate units
6 different delegate and 4 chairman units are available
for the Wired Confidea Digital Conference &
Interpretation System. All versions of the delegate units
are equipped with varying levels of functionality. There
is also one type of interpreter unit available. The
delegate units differ from each other in the following
features:
• a priority button for the chairman versions of the
delegate units.
• An Oled display for channel selection and listening
level indication, and two digital UP/DOWN buttons
for language selection.
• 5 or 3 voting buttons .
• an Oled display for voting related information or
other relevant information.
These features are only available on certain delegate
units. We will present and explain each of these
delegate units. Next to the delegate units the interpreter
unit will also be presented and explained.

The CONFIDEA CU is able to serve conference
systems in a non-coupled environment with up to 120
units. For larger systems with a maximum of 1024
terminals, you can interconnect up to 40 central units
via the system cables. The CONFIDEA CU is an
integration of a microphone system and an interpreter
system.
The CONFIDEA CU’s menu control allows you to:
• set the conference system to one of the 10 different
operating modes (note however that some are only
relevant in an environment where there is a PC
connected to the central unit with the microphone
management software),
• set the delegate unit’s audio options like volume,
automatic gain reduction, low, middle and treble,
• configure the options of the microphone system and
the interpreter system,
• initialize the microphone and interpreter system,
• specify the auxiliary IN/OUT settings,
• reset the microphone and interpreter system,
• configure the language options of the interpreter
desks and booths,
• save the configuration for the interpreter system as
Config1 or as Config2,
23
• load the configuration for the interpreter system
from Config1 or from Config2,
• and more.
Via the two XLR-3F sockets (AUDIO IN 1 & 2) of the
central unit you can connect microphones with suitable
preamplifiers or you can feed audio signals from
additional audio equipment to the conference system.
The output signal of the floor speech is available on the
XLR-3M audio output (AUDIO OUT). Via the XLR-
3M audio output you can:
• connect a public address system and transmit the
audio signal of the floor speech via the public
address system,
• transmit the audio signal of the floor as “original
soundtrack” to a broadcasting station.
It is also possible to connect an infrared language
distribution system to the CONFIDEA CU, allowing
guests or participants who don’t have their own
conference unit to follow the conference via infrared
headphones. The guests or participants can also choose
between the floor channel and up to 28 additional
language channels.
You can also connect an analog output panel (AOP) to
the CONFIDEA CU. The purpose of the analog output
panel is to provide the system with additional analog
outputs. A total of 9 XLR-3M ports are available to
send an analog signal out to other devices, for example,
a recording device or a public address system.
A D-sub connector with 6 analog outputs is also present
on the central unit for analog outputs. The technical
specification of the connector is explained further in this
manual under “Connecting equipment to the AUX
OUT”.

Repeater for the system (*)
A repeater is used to strengthen the signal on a system
cable. When a system cable reaches a length of 80 m,
the signal over the system cables becomes too weak.
We can insert a repeater after the lengthy system cable
to strengthen this signal.
The repeater box has two ports, the IN and OUT port.
The RJ-45 OUT connector (1) should connect a cable
string with a delegate unit and the CONFIDEA CU
should be connected to the RJ-45 IN connector (2) of
the repeater.
The power supply (DC) which reaches the repeater is 30
@ 60 VDC straight from the central unit.
It is also allowed to attach a string of delegate units to
the CONFIDEA CU and then when a system cable
between two delegate units reaches 80 m to insert a
repeater. As you can see, the coloring of the RJ-45 ports
on the repeater is similar to the coloring of the RJ-45
ports of the delegate units. This makes connecting it to
delegate units quite straightforward.
(*) Important Remark :
Repeaters are devices without automatic input/output
detection , so may NOT be used in branches where
devices , with automatic input/output detection (like
Confidea-L units) , are used !

The LEDs of the repeater:
The repeater box has, next to the two RJ-45 connectors,
three LEDs:
• UPLINK FAIL: lights up when there is no
communication with a delegate unit.
• DOWNLINK FAIL: lights up when there is no
communication from the CONFIDEA CU.
• POWER SUPPLY: should always lights up,
whenever the repeater has power.
28
The system cables
The system cables required for the planned conference
system are included in the delivery if they were ordered.
These cables have RJ-45 shielded connectors. The
length of the system cables may range between 0.5 m
and 80m.
With these cables, you can:
• interconnect the delegate units,
• interconnect up to 40 central units for setting up
large conference systems,
• interconnect with an analog output panel.
Via the system cables you can connect the cable strings
with the delegate units to the CONFIDEA CU.

Structuring the Wired Confidea Digital Conference & Interpretation System
Expansion stages This chapter provides information about possible
conference room configurations. It will be explained by
using some example set-ups on how your conference
system can be structured. The components which are
required for the different expansion stages will also be
discussed.
Finally, this chapter also gives an overview of the
additional audio equipment that can be connected to the
conference system.
Possible expansion stages
Depending on the number of conference participants,
four different expansion stages are distinguished as
examples. These expansion stages will show you some
possible set-ups of the Wired Confidea Digital
Conference & Interpretation System. It is possible to set
up a diverse set of configurations depending on the
requirements of the user and the conference room.
These expansion stages should help you tackle any
problems while setting up a configuration.
• Expansion stage (1) comprising up to 20 terminals
• Expansion stage (2) comprising up to 120 terminals
with various kinds of terminals
• Expansion stage (3) comprising up to 600 terminals
In all the configurations, the conference terminals are
interconnected and powered via the system cables
30
which also transmit the digital audio and status
information.
Note:
In the following examples, the standard length of “3m”
is always given for the system cables between the
conference terminals. However, it is not a problem to
use other cable lengths or cables of differing length
within the same string of delegate units.
To make sure that all the delegate and interpretation
units are supplied with a sufficient voltage level, please
refer to the chapter “Determining the maximum cable
lengths”.
Expansion stage (1): up to 20 conference terminals
In small conference system configurations (expansion
stage 1), you can start with 20 conference terminals
connected to one CONFIDEA CU.
Note:
The number chosen here: 20 is only a sample number,
the real number of terminals depends on the
requirements of the user and the conference room.
Example 1:
The maximum distance between the central unit and the
first conference terminal or two conference terminals
may not exceed 80 m without a repeater. Normally the
length of the system cables between two conference
terminals is typically 2 or 3 m. If you interconnect the
maximum number of conference terminals in one string,
the length between the central unit and the first
conference terminal may not exceed 80 m without a
repeater. In the discussion of the expansion stages and
the examples, we will use a length of maximum 80 m
for the first system cable.
31
Note:
Next to these requirements the total length of the cable
string which connects all the terminals to the central
unit should not exceed a specific length. This length can
easily be calculated for your desired configuration. We
can provide you with a power calculator tool that can be
used to simplify the calculation of this length.
Up to 20 conference terminals can be interconnected in
one string. All 20 terminals can be powered via the
CONFIDEA CU’s integrated power supply unit.

Instead of interconnecting 20 terminals in one string
you can also split up the terminals into three different
strings:
Example 2:
The CONFIDEA CU’s integrated power supply can
power up to 120 terminal units which can be split up
into six different strings. In our expansion stage we only
have 20 terminal units which we will split up into four
different strings. Each of these strings will have 5
terminal units attached to it.
The distance between the CONFIDEA CU and the first
conference terminal of a string may vary, but the
maximum distance of 80m without a repeater may not
be exceeded. The length of the system cables between
two terminals is typically 2 or 3m.

Expansion stage (2): up to 120 terminals with various kinds of terminals
In conference system of expansion stage (2), up to 120
terminals can be connected to the CONFIDEA CU.
Example:
The maximum distance between the CONFIDEA CU
and the first terminal may not exceed 80m without a
repeater. The distance between the conference terminals
is typically 2 or 3m. Since the CONFIDEA CU’s
integrated power supply can only supply power for a
maximum of 120 conference terminals, it is discouraged
to attach more conference terminals. When you do
decide to attach more than 120 terminals to a central
unit, then a correct operation of the system cannot be
guaranteed.

Expansion stage (3): up to 600 terminals with various kinds of terminals
You can connect a maximum of six cable strings with
up to 120 terminals to one CONFIDEA CU. For larger
systems with up to 1024 terminals, you therefore
require a total of nine CONFIDEA CUs. One of these
central units is master. The additional CONFIDEA CUs
are connected as “slaves” to the central unit configured
as master. In an environment where the microphone and
conference system is controlled by a PC, the PC must
be connected to the “master” central unit.
In this expansion stage a total of four CONFIDEA CUs
are needed to control all the microphone and interpreter
33
units. You first have to interconnect all the cable strings
to the CONFIDEA CU. A maximum of 20 terminals
can be interconnected in one string, and a total of six
strings can be attached to the central unit. After
interconnecting all the strings and attaching all the
strings to the appropriate CONFIDEA CU we can begin
to interconnect the central units. How the central units
are interconnected is described in the topic
“Interconnecting multiple central units”.
The distance between a CONFIDEA CU and the first
conference terminal of a cable string may not exceed
80m without a repeater. The length of the cables to
interconnecting the central units should be kept as short
as possible and certainly not exceed 80m.

Determining maximum cable lengths
In the preceding examples, the standard length of “3 m”
is always given for the system cables between the
conference terminals. However it is no problem to use
cables of different lengths within the same string.
If you want to use longer cables, make sure that all the
conference and interpreter terminals – including the last
one in the string – are supplied with a voltage of at least
30V!
Calculating the voltage drop on the system cables
Every meter of cable and every conference terminal in a
string causes a voltage drop. Thus the further back a
conference unit is located in a string, the less voltage it
receives. We have constructed a power calculation tool
to automate the calculation of the lengths of these
strings. The sheet is an easy method to calculate the
voltage drops on the individual sections of a sting. This
way, you know before setting up the conference and
interpreter system whether the system will function
correctly or not.
35
Additional equipment for your conference system
Connecting external audio sources
Via the XLR-3F socket of the CONFIDEA CU, external
audio sources which output a balanced mono signal can
be connected to the conference system. External audio
sources are, for example:
• wired microphones,
• wireless microphones,
• the audio channel of a video,
• a CD player,
• etc.
Transmitting a channel to broadcasting and TV stations
Important conferences and specialist congresses are of
great interest to the public. The Wired Confidea Digital
Conference & Interpretation System therefore allows
you to either transmit the floor speech via the XLR-3M
or SUB-D audio output (AUDIO OUT 1). On the
AUDIO OUT 2-3-4-5-6 you can output up to five
interpreter channels/speeches of your choice.
With an AOP2500 Analog Output Panel system you can
output more channels for recording or broadcasting via
the additional XLR-3M ports on the AOP2500.
Transmitting a channel to a Public Address system
Via the central unit’s (or the AOP2500) XLR-3M audio
output, you can connect a PA system to which the floor
speech/channel can be transmitted. This public address
system can then broadcast the sound in e.g. the foyer or
another room.

Transmitting a channel via an infrared transmission link
You can connect the control of an infrared transmitter,
allowing guests or participants who don’t have their
own conference terminal to participate in the conference
via infrared headphones. These guests or participants
can then choose between the floor speech/channel and
the interpretation channels.

Setting up the conference system
Installing and interconnecting This chapter provides information on how to set up the
Wired Confidea Digital Conference & Interpretation
System.
Preparing the Wired Confidea Digital Conference & Interpretation System components for set up
Conference and interpretation units
The conference and interpretation units are “factory-
prepared” to allow immediate use, i.e. after unpacking a
unit, you simply have to plug it into a central unit and
initialize the microphone.
Central unit
• Connect the mains cable to the appropriate
socket (21).
• Connect the mains cable to the mains (100-240
V, 50-60 Hz).
Rack-mounting the system components
For larger conference systems, we recommend
mounting the system components into a rack.

Interconnecting the components of the conference system
Depending on the expansion stage of your conference
system, you have to:
• interconnect the conference terminals (all expansion
stages),
• interconnect the central units,
• connect a PC to the “master” central unit if the
system is to be PC controlled (PC control optional).
Interconnecting the conference units
The conference units are interconnected via the RJ-45
shielded connectors on the back of the conference units.
The IN connector is colored grey and the out connector
is colored black. The system cables have a grey and a
black connector to guide you during the interconnection
of the terminals.
Free Input/Output connectivity in a specific branche is
only possible when only Wired Confidea units (=
Confidea-L) are used in that branch . When TCS2500
delegate or flushmount combipanels are used in the
same branch as Confidea-L units , then Input/output
connectivity of TCS2500 and Combipanels must still be
respected!
Connecting a cable string to the central unit
After having interconnected the conference units, you
have to connect these strings to the CONFIDEA CU.
You can connect up to six cable strings to one central
unit.
• Connect the cable string to one of the RJ-45
shielded connector sockets labeled: PORT 1, 2, 3, 4,
5 or 6.
• When the length of the cable to the first conference
unit, or when the length of the cable between
conference units is 80m; then a repeater should be
placed between the central unit and that delegate
unit or between the two delegate units.
• To see additional information about the repeater and
how to connect the repeater to the central unit and a
delegate unit and/or between two delegate units see
the paragraph on: ‘Repeater for the system’.

Interconnecting central units
Chain topology
The best approach is to mount the central units into a
rack. In the chain topology we interconnect the
CONFIDEA CUs via the RJ-45 shielded connector
sockets (SLAVE IN, SLAVE OUT and MASTER
OUT) at their rear. The CONFIDEA CU which is
master has an FTP-CAT5 cable connected to the
MASTER OUT port. The SLAVE IN and SLAVE OUT
ports are then used for the central units which are slave.
• At the first CONFIDEA CU, connect the end of
the system cable to the MASTER OUT socket.
This central unit is now master.
• Connect the other end of the system cable
(coming from the master unit) to the SLAVE IN
socket of a second CONFIDEA CU.
• For multiple slaves, connect the SLAVE OUT
from the first slave to the SLAVE IN from the
next slave.
• Configure the slave central units so that the
master-slave symbol ( ) is displayed on the
main menu item. Please refer to the explanation
for the main screen for more details on this
symbol.
Star topology
When the conference room has a high number of
coupled central units, it might be better to use a star
topology. In this topology we interconnect the slave

CONFIDEA CUs via the RJ-45 shielded connector
sockets (SLAVE IN) at their rear with the master
central unit via the connector sockets (MASTER OUT,
SLAVE OUT or PORT 1-6) or with a slave central unit
via the connector sockets (MASTER OUT, SLAVE
OUT or PORT 1-6). The CONFIDEA CU which is
master has an FTP-CAT5 cable connected to the
MASTER OUT port or/and a cable connected to PORT
1-6 or SLAVE OUT. The SLAVE IN port are then used
for the central units which are slave. If necessary the
MASTER OUT, SLAVE OUT port or PORT 1-6 of the
slave central units can also be used to further extend the
star topology
• At the first CONFIDEA CU, connect the end of
the system cable to the MASTER OUT, SLAVE
OUT or PORT 1-6 socket. The central unit will
be master as long as no cable is inserted in the
SLAVE IN port of the central unit.
• Connect the other end of the system cables
(coming from the master unit) to the SLAVE IN
socket of the slave CONFIDEA CUs.
• For large star topologies, connect a system cable
between the SLAVE IN port of a central unit
and a SLAVE OUT, MASTER OUT or PORT
1-6 of another slave central unit
• Configure the slave central units so that the
master-slave symbol ( ) is displayed on the
main menu item. Please refer to the explanation
for the main screen for more details on this
symbol.
General
Briefly: A CONFIDEA CU is able to go into slave
mode if the master-slave symbol is visual ( ). A
slave CONFIDEA CU is identified by a connection on
its SLAVE IN port and the slave symbol ( ).
If the SLAVE IN port is not connected then it is
automatically a master central unit ( ). The output
port that connects with the SLAVE IN port can be the
SLAVE OUT or the MASTER OUT port or one of the
6 digital bus ports. Typically the MASTER OUT and
the SLAVE OUT will be used for coupling, but in an
alternative configuration you can use them to add extra
conference units with an external power supply.
The startup sequence of the central units is randomly.
Do keep in mind that the startup of the central units, in a
41
coupled environment, can take a considerable amount of
time. All the units connected to all central units in the
configuration have to be processed. The central unit will
react slower to user input during this phase. Once the
system is fully initialized, everything will react
normally. This initialization time is dependent on your
configuration. The basic principle applied here is: the
larger the configuration, the longer the initialization
time.
The CONFIDEA CU which is master can be used to
configure all settings. The other CONFIDEA CUs
which are slave are locked and will display the locking
symbol ( ) in the lower right corner of the screen of
the CONFIDEA CU. You cannot alter any settings on a
slave central unit. Go back to master mode, by pressing
the F2 button for 3 seconds, if any settings need to be
altered.

Connecting additional equipment
Connecting headphones to a conference unit
• Connect headphones to the 3.5 mm mono jack
socket.
• First, use the level control to reduce the headphone
volume to the minimum.
• Slowly set the volume to a medium level.
When people use headphones, they tend to choose a
higher volume than with loudspeakers. Listening at high
volume levels for long periods can lead to permanent
hearing deficiency. Please protect your hearing!
Connecting the analog output panel
You can connect an analog output panel (AOP2500) to
the central unit for audio output. The DATA OUT
socket on the CONFIDEA CU should be connected to
the DIGITAL IN socket of the AOP2500.
Connecting an external audio source
You can connect external audio sources such as wired
microphones, wireless microphone systems, the audio
channel of a video recorder, a CD player, another
conference unit for remote conferencing, etc. to the
conference system. The audio sources to be connected
must deliver a balanced mono signal at the XLR-3F
socket (8). Depending on the strength of the audio
signal, you can increase the input sensitivity of the
conference system in the central unit’s operating menu.
Connect the audio sources as follows:
• Connect the audio source to one of the XLR-3F
sockets of the central unit.
• If necessary, adapt the input sensitivity in the
operating menu.

The aux out numbers described in the above illustration
relate to aux out 1 - 2 – 3 – 4 – 5 – 6 in the menu of the
CONFIDEA CU. For example: if you change the
channel assigned to aux out 3 on the central unit, then
these changes will be noticed on the 3-11 pin
combination.
The floor speech/ channel signal is transmitted on aux
out 1. This channel cannot be changed. The floor
speech/channel signal is also transmitted on the XLR-
44
3M socket. The volume difference between AUX OUT
1 on the SUB-D 15 connector and the AUX OUT 1 on
the XLR socket can be adjusted by changing the
Volume XLR in the AUX OUT 1 menu item. By
default there is no difference.
It is however possible to alter the channel signal for the
remaining auxiliary outputs. You may assign any
interpreter channel or the floor channel to these outputs.
Next to the channel you can alter the volume and the
status (ON/OFF) of an auxiliary output.
The volume difference between AUX OUT 6 on the
SUB-D 15 connector and the AUX OUT on the
headphone jack can be adjusted by changing the Vol.
Headphone in the AUX OUT 6 menu item. By default
there is no difference.
Connecting the PC to the central unit
The PC software consists out of two different parts. The
two distinguishable parts are the microphone
management software (TMS2500) and the interpreter
management software (TIS2500). To connect the PC to
the CONFIDEA CU, when you installed both the
microphone and interpreter management software, you
need two serial ports on your PC. One serial port is
necessary for the conference management software and
the other port is necessary for the interpreter
management software. The COM ports of the central
unit work at a speed of 19200 bits per second.
The port on the back of the CONFIDEA CU labeled
COM 1 is the port associated with the interpreter
management system (TIS2500).
The port on the back of the CONFIDEA CU labeled
COM 3 is the port associated with the microphone
management system (TMS2500).
Note that the software versions will be checked at both
sides before starting the communication. The PC will
check if the CU version is compatible with the PC
software version and the central unit will check if
remote control is allowed by the pc that asks the
connection.
45
The cables necessary to connect the central unit to the
PC are described below.
The diagram of the cable described above is actually a
null-modem cable. This means that a standard null-
modem cable without handschaking can be used to
connect the PC with the central unit ,
Remark : NO hardware handshaking is allowed
(check comport settings)!
46
Turning the central unit on and off
When turning on the power of the conference and
interpretation system, it is important that the
components are turned on in the correct order.
In conference systems with several central units, first
turn on the “master” central unit. Then turn on the slave
units in the sequence they are connected to the master
unit. Please keep in mind that it takes a certain amount
of time until the system has fully started up. The larger
the configuration, the longer it takes to start the system.
During this phase, the menu will react slower to user
input. Once all units are initialized and the system has
started up, the master central unit will react normally
again.
Turning the central unit on
Set the POWER switch (22) in the ON position.
The conference and interpretation units which are
connected to the central unit are now ready for
operation.
The start display appears on the LCD display of the
central unit.
Volume =
P1 P2 P3 P4 P5 P6 Figure 2 - The start-up screen of the central unit
Turning the central unit off
Set the POWER switch (22) in the OFF position.
The conference and interpretation units are now
disconnected from the voltage supply. Switch off the
central units in a coupled configuration starting with the
slaves. Finally switch off the master central unit.

Configuring the conference system
Overview This chapter provides instructions on how to:
• operate the Wired Confidea operating menu,
• initialize the microphone system,
• set the operating microphone mode,
• adjust the audio settings for the loudspeaker,
• activate and configure the auxiliary inputs and
outputs,
• resetting the microphone system,
• access the microphone options,
• configure the interpreter system,
• choose the language options for the different booths.
48
Introduction to the CONFIDEA CU’s operating menu
The startup display
After turning on the central unit, the start display
appears, showing the Wired Confidea Digital
Conference & Interpretation System main menu where
you can choose between six menu choices:
• Conference: contains the configuration of the
microphone system and the delegate units.
• Interpreter: contains the configuration of the
interpreter system and the interpreter booths.
• AUX-OUT/IN: contains the configuration of the
auxiliary outputs and inputs.
• System: contains system wide configuration options
• Language: contains the language configuration of
the CONFIDEA CU’s menu.
• License: contains all license related information and
configuration options.
After approximately one minute the menu will jump to
the volume setting of the delegate loudspeaker. This
happens because the volume setting is accessed most
frequently when using the Wired Confidea Digital
Conference & Interpretation System.
The lock functionality
It is possible to lock the menu of the central unit.
Suppose that you configured the central unit to your
desires and you do not want anyone to alter these
settings. To do this, you have to lock the main screen of
the central unit. This is the screen where you can see the
volume bar.
Navigate to the main menu of the central unit. The
menu can now be locked by pressing the F1 and the F3
button at the same time and keep them pushed for about
two seconds. After you released the buttons the locking
symbol ( ) will be displayed in the lower right corner
of the screen of the central unit. When you try to access
the menu of the central unit by pressing the ENTER
button, nothing will happen. This means that you are
successfully locked out of the menu.
The menu can be unlocked again by the operator
whenever he wants to alter some settings. The sequence
to unlock the menu is the same as the sequence to lock
49
the menu. Press the F1 and the F3 button at the same
time again for about two seconds to unlock the menu.
When the buttons are released the locking symbol ( )
will disappear from the lower right corner of the main
menu.
Note: The locking symbol also appears on certain
central units in a coupled environment. Specifically,
they appear on the slave central units. You can
distinguish a slave central unit from a locked central
unit by the volume bar. A slave central unit has no
volume bar.
The menu buttons
The wheel, ENTER and EXIT button allow you to
navigate through the operating menu.

The menu - explained
Working with the root menu
The main screen
The main screen contains two important elements. The
first is a volume bar which can be altered using the
wheel. During a conference the volume can be set lower
or higher when necessary. The second element is an
indication of the ports. These indicate which ports are
used and to which port a string of conference terminals
is connected. More of this is explained in the section
discussing the system diagnostics.
Two central units can also be coupled to establish a
bigger conference room, controlled by a single, the
master, central unit. More on this coupling can be found
elsewhere in this manual. To indicate that a central unit
is able to work as a slave central unit a sign has been
put in the top right corner on the menu display. If this
symbol is not visible, try to press the F2 for about 3
seconds. If the symbol doesn’t appear, it means you
have a restricted license. When the symbol is visible
and the central unit has detected a master central unit on
the slave port, the central unit will automatically go into
slave mode, the slave symbol will be adjusted like
shown in the picture on the left.
In summary the table below explains the slave symbol.

When a central unit is in slave mode, but some settings
need to be altered like the output channels on the
different analog outputs, you can always go back to the
master mode by again pressing the F2 button for about
3 seconds.

The conference menu - overview
Default values of the microphone system
1 Conference
A number of default values will be loaded into the
System the first time the CONFIDEA CU boots. These
default values ensure a correct operation of the
CONFIDEA CU conference system. However, all
delegate units connected to the central unit will display
an Init Refused screen. This means the delegate units are
not known to the conference system. We should
therefore start with the initialization of the microphone
system.
NOTE : an overview of the default values can be found
in appendix D
Initializing the microphone system
The first time you start using the Wired Confidea
Digital Conference & Interpretation System in a new
set-up you have to begin with an initialization. The
initialization can take place in two different ways. You
have the choice between an automatic initialization and
a manual initialization. Both options have their
advantages and disadvantages, which we will pinpoint
in a moment.
The automatic initialization is very useful when you
want to initialize the conference units without
initializing each conference unit separately. When you
enter the automatic initialization menu, then the
conference units will have initialized themselves. You
will be informed to wait a little. After pressing the
ENTER button the units will be initialized.
If the order in which the conference units are initialized
is important, then you are advised to use the manual
init. When the manual initialization is active, then the
red signal ring of all the conference units will begin to
flash. Notice that only the delegate units will begin to
flash and not the interpreter units! The interpreter units
do not respond to an initialization of the conference
menu because these are managed by the interpreter
subsystem. Pressing the microphone button on the
conference units will signal the central unit that the
Conference

Press ENTER to Save
80
microphone is initialized. If the microphone is accepted
by the central unit, then the red signal ring will stop
flashing. You can now initialize the conference units in
the order you desire.
In case you already have a room configuration set up
which you want to keep, and you want to add a new
unit, then you can opt for the Add Unit menu item.
When the menu item is activated, then the red signal
ring of all unknown conference units start to flash. The
new units may now be initialized by pressing the
microphone button.
In case you want to delete a conference unit from the
configuration, you have to select the microphone
number on the central unit in the Delete Unit menu
item. Once you have selected the appropriate number
and pressed the ENTER button, then you can safely
remove the conference unit.
In case you want to reserve a conference unit you have
to select the microphone number on the central unit in
the Reserve Unit menu item. Reserving a microphone is
useful when you have a room in expansion. Maybe
some place to put e.g. microphone 17 is foreseen in the
future but cannot be set up right now. In this case you
can reserve the microphone for later. The sequence in
which a microphone is reserved is somewhat special
though. To reserve a microphone, you should first enter
the Manual Init – Full Init menu item. Start the full init
and exit the menu item. Then browse to the Reserve
Unit menu item and enter the numbers of the conference
units you want to reserve. After these unit numbers have
been entered, you can start pushing the microphone
numbers of the conference units.
Suppose now that you reserved conference unit number
7 and you have come at a moment when you want to
add conference unit 7 to the configuration. The first
thing you have to do know is activate the Delete Unit
menu item to delete the reserved number from the
conference configuration. Once the unit number has
been deleted, you have to activate the Add Unit menu
item, and press the newly added conference unit. It will
have been initialized with the previously reserved
number.
Note: When you enter the Manual Init – Full Init menu
item, then all data about previously reserved numbers
will be lost.

Choosing the conference mode
By selecting a certain conference mode, you can
strongly influence the character of a discussion:
• you can determine the level of control of the
chairman,
• and you can determine whether the conference
participants can take the floor immediately or if they
have to “apply” for the floor.
Note: A chairman unit is always able to speak! No
matter what mode the conference system is in, the
chairman is always able to speak by pressing his
MICRO button. The chairman can also deactivate all
active conference units by pressing his PRIOR button or
activate the delegate unit that requested to speak by
pressing the NEXT button.
Note: Multiple chairmen units can also be assigned by
using the PC software or by using appropriate menu
item.
You have the choice between 10 different operating
modes. The operating mode is selected in the Operating
Mode menu item. Note however that one mode is only
useful in combination with a PC installed with the
software control suite. This mode is: No request.
Without a PC you can use the With request, With
request – no clear, Direct Access, FIFO, Group 1-4 and
override. With a PC and the software control suite all
the operating modes can be used.
Operating modes:
• No request: the participant willing to speak has to
notify the conference manager that he is willing to
speak. He can do this by raising his hand or any
other means not involving the microphone. Once the
conference manager has noticed that a participant
has requested the floor, he can activate microphone
of the participant or ignore his request. The
conference operator has total control over the
microphones.
• With request: enables the participant to send a
request to the chairman or conference operator by
pressing the microphone button (or to cancel his
request by pressing the microphone button again).
Once the floor is requested, the green LED above
the microphone button will flash. This means that
the conference unit is in request mode. The
Conference

chairman or conference operator grants the
participant the permission to talk by using the NEXT
button or by clicking the green microphone on the
computer screen. While the conference unit is in
request, the red signal ring of the microphone will
flash if this option is selected.
• With request no clear: enables the participant to
send a request to the conference operator. However,
he cannot cancel his request. The chairman or
conference operator grants the participant the
permission to talk by using the NEXT button or by
clicking the green microphone on the computer
screen. During the in request period, the red signal
ring of the microphone will flash if this option is
selected.
• Direct Access: enables the participant to turn on his
microphone at any time. The only limitation here is
the maximum number of microphones which may
be active simultaneously.
• FIFO: enables one microphone at a time to be active
without intervention of the conference operator.
Activation of a new microphone overrides the
current active microphone. The only exception here
is that the microphones of a delegate and the
chairman can be active at the same time.
• Group 1: enables one microphone at a time to be
active without a request for activation. Other
participants may put their microphone in request
mode; the first applicant gets the floor when the
delegate who has the floor turns off his active
microphone or when the chairman or conference
operator grants the participant the permission to talk
by using the NEXT button or by clicking the green
microphone on the computer screen.
• Group 2: enables two microphones to be active at
the same time. Other participants may put their
microphone in request mode; the first applicant who
requested the floor gets the floor when one of the
currently active microphones is turned off or when
the chairman or conference operator grants the
participant the permission to talk.
• Group 3: works exactly like Group 1 and Group 2,
with the alteration that three participants can have
the floor at the same time.
• Group 4: works exactly like Group 1 and Group 2,
with the alteration that four participants can have the
floor at the same time.
83
• Override: works like the FIFO mode, with the
alteration that “MAX # Microphones” participants
can have the floor at the same time. Activation of a
new microphone will overrides the microphone that
was active for the longest time if the total number of
active microphones would exceed the user defined
“MAX # Microphones”. Here we have also the
exception that Chairmen units can always be
activated.
Max number of microphones simultaneously active
In the operating mode No request, With request, With
request – No Clear and Direct Access the maximum
number of microphones which may be active is
relevant. This number can be set in the Microphone
Limit menu item. The range of this value is between 1
and 15.
Adjusting the audio settings for the loudspeaker
By selecting the Loudspeaker menu item you can alter
the audio settings of the conference unit’s loudspeakers.
It is possible to adjust the volume, the low, the middle
and the treble audio settings. The volume can also be
adjusted when the menu jumps back to main menu.
Turning the wheel button will automatically change the
volume. If you choose to save the settings, then these
settings will be stored in the central unit so that the next
time the system boots these settings will become active
automatically.

Adjusting the audio settings for the microphone
By selecting the Microphones menu item you can alter
the audio settings of the conference unit’s microphone.
It is possible to adjust the automatic gain reduction, the
low, the middle and the treble audio settings. The
limiter gain of the microphone can also be set. Turning
the wheel button will automatically change the audio
setting. The automatic gain reduction indicates how
much the gain will be reduced when multiple
microphones become active. The higher the number, the
higher the reduction will be for multiple microphones.
If you choose to save the settings, then these settings
will be stored in the central unit so that the next time the
system boots these settings will become active
automatically.
The following graphic shows the automatic gain
reduction in function of the number of microphones that
are activated. The gain reduction is indicated in decibel
and referenced to the gain for one active microphone.
Each graph indicates an automatic gain reduction
number that can be set on the central unit. Note that
although the maximum number of microphones is 15,
the curves stop at 9. When more than 9 microphones are
activated the gain reduction will be kept constant.

It is possible to adjust the limiter gain curve for the
microphones by setting the desired offset value in dB.
This is especially used to determine the reach for the
microphones. So it is possible to exclude the noise in a
room from amplifying. In a room with much noise only
the speakers’ voice will be amplified and not the noise.
Lowering the limiter gain will result in a shorter reach,
otherwise stated: only the sound of sources close to the
microphone will be amplified.

Configuring the chairmen
Multiple chairmen units can be assigned in the
Chairmen menu item. By default, during initialization,
only one chairman unit will be assigned. One can
assign up to 50 chairmen units for a single conference
configuration. The picture below shows how to assign
multiple chairmen units:
• By entering the Set Chairmen menu item, a
chairman index number can be selected. Note
that the first two digits are marked. The first two
digits represent the chairmen index number in
the range from 1 to 50 because 50 chairmen
units can be assigned. We start with the first one
so we scroll to number 1 by using the wheel
button. After the correct index number has been
reached, press the ENTER button.

• Note that after hitting the ENTER button the
right four digits are marked, These digits
indicate the delegate unit that will be configured
as chairman. In this example we want to select
delegate with number 3 as chairman so we scroll
to number 3 by using the wheel button.
• Next, to confirm the settings press the ENTER
button again. The delegate with number 3 is now
configured as a chairman unit. Note that now the
index number is marked again, making it
possible to assign another chairman unit.
• If more chairmen units are desired, repeat the
same steps but now with a different chairmen
index number.
The chairmen list can be cleared by entering the Clear
Chairmen menu item and hitting the ENTER button.
NOTE 1: When the conference room is controlled by a
PC, the local chairmen settings will be overwritten by
the PC settings.
NOTE 2: When the delegate units are reinitialized, the
chairman settings are cleared.
Resetting the microphone system
If for any reason the system has to be reset, you can do
this in the Reset menu item. Only the microphone
system will shut down and start up again immediately.
This will not affect the interpreter system.
Accessing the microphone options
The microphone options are the Options menu item.
The menu item contains a number of menu items which
allows the conference system to be checked and to
adjust some general settings. Two test modes can check
the sound of the delegate loudspeakers and can check
which microphones are connected to and initialized by
the CONFIDEA CU.
The Test Tone is used to generate a test tone on all
loudspeakers of all delegate units. The Test Units option
will activate the micro of all delegate units one by one
in the sequence they were initialized. Once the test

sequence reaches the last unit, it will automatically
restart the test.
The Test Tone comes in useful when you are testing the
loudspeakers of the delegate units. Activate the Test
Tone option whenever you are not sure that the
loudspeaker of a delegate unit is working correctly. The
Test Units option is useful when you initialized the
delegate units and you want to test if there were all
initialized correctly. The delegate units will only
activate when they are known to the system.
The third item in the Options menu allows you to set the
behavior of the red signal ring on a delegate unit during
request. You can choose to let the signal ring blink
along with the green request led or you can choose to
only let the green request led blink on the unit in
request.

The conference menu - example Suppose the following circumstances apply: a Wired
Confidea Digital Conference & Interpretation System
needs to be set up in a conference room in which a
meeting with 10 participants will occur. One of these
participants is a chairman and the participants will have
to vote during the conference. We will need up to 10
conference units for our system of which one
conference unit is a chairman unit.
To be able to configure this configuration we would
need for instance the following hardware: one
CONFIDEA CU, one Confidea_L CV and nine
Confidea-L DV units.
Let’s start setting up the system starting from a default
configuration. The setup will be described one step at a
time to make it easier to understand. If you feel that the
discussion of the setup is too detailed, feel free to skip
this section.
The starting point of the steps that needs to be taken is
the main screen of the central unit unless noted
otherwise.
Loading the default settings
Start by loading the default setting for the conference
desks. We start from the main menu.
• Press ENTER, choose Conference. Press ENTER
again, now choose Initialize units. Press ENTER.
Now choose Load Defaults, press ENTER. Press
ENTER again to load the default values.
• To go back to the main menu, repeatedly press the
EXIT button until you reach the main menu.
• Now that the default values have been loaded; we
need to reboot the system. Start from the main menu
again. Press ENTER, choose Conference. Press
ENTER again, now choose Reset. Press ENTER
again to reset the conference system. Now go back
to the main menu.
Select the operating mode
We want to select our mode of operation. The
differences between the different modes of operation
are explained above.
• Press ENTER, choose Conference. Press ENTER
again, now choose Operating Mode and press
89
ENTER. Select the operating mode and press
ENTER to save the operating mode.
Changing the delegate loudspeaker settings
The audio settings of the delegate loudspeaker can be
changed if for instance the volume settings of the
delegate loudspeakers are too low.
The volume setting of the loudspeakers of the
conference units can easily be changed in the main
menu by turning the wheel. The setting isn’t saved
however. If you want to save the setting you must go
through the following sequence of steps.
• Press ENTER, choose Conference. Press ENTER
again, now choose Loudspeaker. Press ENTER and
choose Volume. Press ENTER and turn the wheel to
set the volume to the desired value. Press ENTER to
save the adjusted volume level.
• If you want to change the Low, Middle or Treble
settings, go through the same sequence as described
above and select the Low, Treble or Middle menu
option. Save your settings and exit the menu.
Changing the delegate microphone settings
The audio settings of the delegate microphone can be
changed if for instance the gain is to high when multiple
microphones are activated.
The automatic gain reduction setting of the conference
units can be changed by following the next sequence of
steps.
• Press ENTER, choose Conference. Press ENTER
again, now choose Microphones. Press ENTER and
choose Auto Gain Redu.. Press ENTER and turn the
wheel to set the gain reduction to the desired value.
Press ENTER to save the adjusted gain reduction
level.
• If you want to change the Low, Middle or Treble
settings, go through the same sequence as described
above and select the Low, Treble or Middle menu
option. Save your settings and exit the menu.
Changing the maximum number of microphones which may be active simultaneously
Press ENTER, choose Conference. Press ENTER again,
now choose Microphone Limit. Press ENTER. Turn the
90
wheel to alter the maximum number of microphones.
Press ENTER to save your settings.
Initializing the conference units
There are 2 options during the initialization, an
automatic and a manual initialization. In most of the
cases an automatic initialization will suffice. The
manual initialization is most handy when you want the
delegate units numbered in a desired sequence.
The automatic initialization is self-explanatory; to
initiate it, execute the following sequence.
• Press ENTER, choose Conference. Press ENTER
again, now choose Initialize Units. Press ENTER,
choose Automatic Init. Press ENTER. Wait until the
menu displays “Press ENTER to save
initialization”, then press ENTER.
• The manual init consists out of four parts. We have
a Full Init, an Add Unit, a Reserve Unit and a Delete
Unit menu choice. The purpose of these menu
choices has been explained above. The steps which
need to be taken are similar to the example given
below.
• To manually initialize the conference units execute
the following sequence: Press ENTER, choose
Conference. Press ENTER again, now choose
Initialize Units. Press ENTER, choose Manual Init.
Press ENTER and choose Full Init. Press ENTER.
The red signal rings of the conference units will
start flashing. Press the MICRO button of the
conference units in any sequence you desire. After
pressing the MICRO button the red signal ring stops
flashing, this means that the conference unit is
initialized.
• Go back to the CONFIDEA CU and press the
ENTER button to save the configuration.
• Congratulations, the system has been initialized.
To add a conference unit, execute the Add Unit menu
option. The red signal ring of the new conference units
will start flashing. Press its MICRO button to initialize
it.
When you want to delete a conference unit from the
current configuration execute the Delete Unit menu
option.
91
• Select the number of the microphone you want to
delete. Press ENTER to delete the microphone.
The Reserve Unit menu option has been explained
above as well as the steps to take.
Let the red signal ring blink in request mode
To let the red signal ring blink along with the green
request led above the microphone button follow the next
procedure.
Press ENTER, choose Conference. Press ENTER again,
now choose Options. Press ENTER and choose Light
Ring. Press ENTER and turn the wheel to set the light
ring in Blink at Request mode. Press ENTER to save this
setting.
Working with delegate conference units
Talking: The most important button on a conference
unit is the MICRO button. The MICRO button is used to
speak or to issue a request-to-speak. When you have to
request the floor to take the word, you need to press the
MICRO button. The green LED above the MICRO
button will then begin to flash along with the red signal
ring if this option is chosen. The chairman unit or a
conference manager which has a PC with the
microphone management software installed is able to
grant you access to the floor. Once you have been
granted the floor the red signal ring will light up.
Translations: To listen to the translated floor channel
you must have a conference unit with a channel
selector. To change the channel, press the up and down
buttons above and below the channel selector. You will
then hear the translation of the floor channel in your
headset.
Voting: You can only vote when the voting session has
been started by the chairman. For this you need delegate
units with voting possibility. Once the voting session
has started, you will notice that you have a choice for
your vote. These screens are depicted on the left. To
vote press the button under the value of the vote you
want to cast. The vote will then be registered. Once the
voting session is over, the results will be shown on the
display.
92
Working with chairman conference units
Priority: The chairman unit works in the same way as
the delegate unit, but has three extra options. The first
extra option is the PRIOR button. The prior button can
be used in two ways. It can be used to mute all currently
active delegate microphones or is can be used to
deactivate all of the active delegate microphones.
All the active microphones of the delegates will be
deactivated when you press the PRIOR button and
release it quickly. Just tapping the PRIOR button will do
just that.
By keeping the PRIOR button pressed down, you can
mute all active delegate microphones. When you release
the PRIOR button, then all muted delegate microphones
will become active again. All requests for the floor are
ignored while all delegate microphones are muted. Once
the PRIOR button is released, the conference can
proceed again in its normal operation
Voting: The second option is the possibility to start the
voting. However, voting is only possible with units
which have voting possibility. The display menu on the
chairman’s unit can be chosen by pressing the PLAY or
STOP buttons. At startup the screen of the chairman
unit looks like the figure depicted on the left. Note
however that when the conference room is controlled
with a PC the chairman units can no longer start a vote
session as this can be done using the conference
software.
Next request: The third option is to grant a delegate unit
access to the floor if he requested the floor to take the
word. On the Confidea-L CD , CV and CIV the NEXT
button is used to grant the floor to the first in request .
93
The interpreter menu - overview Next to the conferencing functionalities of the Wired
Confidea Digital Conference & Interpretation System
we have an interpreter system. The interpreter system
works closely with the interpreter desk units (ID2500),
so you have to have access to these units when you
want to use the interpreter system.
Usage
We will explain how the interpreter system is used with
an example. Let’s suppose we are in a conference room
where three different languages are spoken and where
the participants of the conference do not understand a
language different from their native tongue. The three
spoken languages are English, French and German.
Let us now suppose that six interpreters are at out
disposal and that we have six interpreter units for the
interpreters to use.
The interpreter unit may be mixed with the normal
conference units on a string or they may all be on the
same string. The good way to set up the interpreter
terminals is to divide them in three separate booths.
Three booths are set up with, in each booth, two desks.
We allow the interpreters to relieve each other by
setting up two desks in a booth. The booth and desk
number is configured on the interpreter desk (ID2500
unit) while you are in the initialization mode.
The first booth is assigned to the English language, this
means that its A channel is assigned to ENG. The
second booth is assigned the French language, so its A
channel is assigned to FRE and the third booth is
assigned to the German language so its A channel will
be GER.
Next to the A channel there is also a B channel. The B
channel of each booth and therefore each desk can have
another language assigned to it. This language depends
on the preferences of the interpreter as he can choose
his desired language.
If the interpreter knows more than one language, i.e. the
interpreter understands ands speaks English, German
and French; then he’ll be able to translate to each of
these languages. This means that even though the A
94
channel of a booth is fixed to a specific language, he
will be able to translate to the other languages on the B
channel.
Configuration
The Configuration menu allows you to make a
completely new configuration, alter the settings for the
current configuration or load a previous made
configuration. In the new and current menu you can
select a booth and alter the settings for that booth. The
settings that can be altered are the Language, the Auto-
floor and the B-channel. When you alter the settings of
a booth you have to remember to save the settings for
each booth. At the end of a configuration you can
choose to save the interpretation configuration as
Config1 or Config2. Not saving the settings or exit at
the end leaves the current configuration unchanged even
when you began a new configuration.
New Configuration
When you begin with a new configuration, by pressing
the enter button, the previous settings in the interpreter
system will be cleared. The settings for each booth can
now be configured.
NOTE: Don’t forget to save the configuration as
Config1 or Config2 after you altered and saved the
settings for each booth.
It is recommended to change the parameters in the
option menu, if necessary, after you made and saved a
new configuration.
Current Configuration
Entering the current menu you can make corrections on
the current configuration without deleting the settings
for each booth made previously. You will be able to
adjust the settings like explained below.
Saving Configuration
After altering the language settings for each booth,
starting from a new configuration or continuing with the
current one you will be asked to save the configuration.
You can choose to save it as Configuration 1 or
Configuration 2. Not saving the configuration (or exit)
brings the interpreter system in the same state as it was
before you entered the configuration menu.

95
Load Configuration
A previously saved interpreter configuration can be
loaded. You can choose from 2 independent
configurations. After a load there will automatically be
a reset which will reboot the interpreter system without
affecting the conference system.
Not only the language settings for each booth will be
loaded but also the parameters in the option menu and
the initialization settings that were made after you saved
the configuration file. Although, you can alter these
parameters and initialization settings after a load
without affecting the language settings for all booths. In
this case a reboot will be necessary. This can be done by
activating the reboot in Reset menu item.
Choosing the language options for the different booths
A channel - Language
Through the language setting we can change the A
channel language of the booth. The A channel language
is the language to which a booth is assigned. For
example, when multiple languages are spoken during a
conference and the French language is one of the
spoken languages. Then you would add an interpreter
booth which translates the French language to e.g.
English and make the booth responsible for the English
language. To do this you would set its A channel.
B channel
The B-channel is the second language an interpreter
understands and speaks fluently. For example, Bob is
born in the U.K. and thus speaks English fluently. He
has studied the French, Spanish and Italian languages
which he understands and speaks fluently. He has been
assigned to the booth responsible for the English
language. During the conference English and French are
spoken. Bob translates the floor language to English
whenever French is spoken. Suppose now that Bob is
also responsible for the translation from English to
French. To translate to the French language Bob sets his
B channel on the French language.
In short: A translator may be responsible for multiple
languages. To be able to translate to these languages the
interpreter configures his interpreter desk accordingly.
The A channel is thus the main language the interpreter

Load
Configuration 1Press ENTER to Load
96
is responsible for (which cannot be changed from the
interpreter desk) and the B channel is the second
language an interpreter is responsible for (which can be
changed from the interpreter desk).
When you access the B-channel menu option you are
presented with a numeric choice. These numbers
represent the booths in the system. This option is
important when you want a specific language on your
B-channel after startup. Suppose you have three booths:
booth one is English, booth two is French, booth three is
German. For the third booth you want the B-channel to
be set to English as a default setting. Then you set the
B-channel to 1 during the configuration of the booth.
Remember though that the B channel can be changed on
the interpreter desk.
Auto-floor
Next to these settings the auto-floor option can be
activated. The auto-floor setting concerns working with
the B Channel on the interpreter unit. In circumstances
where the original floor-language is well known or not
so well known, two different operational procedures can
be used. Under normal circumstances the original floor
language is well known to all interpreters and they
listen to the original floor speech for translation. The
translations are then fed to the language distribution
channels so that the conference participants can listen to
them. In situations where interpreters are unfamiliar
with the floor speech and are therefore unable to
translate it, the system offers an automated relay
interpretation facility (auto-floor). An interpreter
assigned to translate the floor speech, translates it into
another language easily understood by other
interpreters. The floor language channel on all
interpreter desks (except the floor language channel of
the interpreter which translates the floor speech) will be
replaced by this transfer interpretation. This transfer
interpretation or auto-floor is then used as the base for
any further translations.
We have included two illustrations which explain the
normal interpretation and the relay interpretation for a
better understanding.
The first illustration show how a normal interpretation
works. Every interpreter translates the floor language.

In the next illustration, Russian is the floor speech and
the auto-floor facility is enabled for the Russian
interpreter’s desk. This interpreter selects outgoing
channel B and automatically relays an English
translation of the floor speech as auto-floor to all other
interpreter desks. His translation is therefore fed to the
English language distribution channel. The incoming
channel AUTOFLOOR indicator is activated on all
other interpreter desks to indicate that auto-floor is
active.

Auto-Floor
In short: Well, whenever an exotic (auto-floor) language
is spoken on the floor, it is translated. And it is this
translation of the floor speech that is used as a basis for
translation. Notice that the floor channel for the
98
delegates will not change. Auto-floor only concerns the
interpreter side of the system.
Initializing the interpreter system
When the full initialization of the interpreter system is
executed, all of the red signal rings of the interpreter
units will start flashing. The screen depicted on the left
will then appear on all interpreter desks. You will have
to manually configure the booth and desk number on
each interpreter unit. Press the MICRO button to send
the configuration data to the central unit. You will
notice that the other booths will have incremented their
BOOTH / DESK value. This allows you to step through
the initialization without much configuration.
You can end the initialization at the central unit after
you have initialized all interpreter desks end
Once the initialization is done, the LCD displays of the
interpreter units will show the different channels (A &
B) and other information.
If something went wrong during initialization then the
interpreter units will display an init refused screen.
When this happens you should try to reinitialize your
booths. If this doesn’t correct the problem check your
booth configuration.
When you traverse the Initialize Units menu you will
notice that there is an Add Unit menu option. Suppose
that we have an up and running system but you only
have one interpreter desk in the second booth and you
want to add another. You should then choose the Add
Unit menu item. The red signal rings of the interpreter
desks will now start flashing again and they will all
show the initialization screen (which is depicted in the
beginning of this section). You do not have to
reconfigure the interpreter desks you already initialized
previously. So go directly to the new interpreter unit.
Configure the booth and desk number of the new
interpreter unit and confirm your configuration.
Rebooting the interpreter system (TIS)
It is good practice to reboot the interpreter system
whenever you have made changes to your configuration
at the central unit. Rebooting the interpreter system
does not affect the conference system. This means that
you can make changes to the interpreter system during a
conference.

After loading a configuration from the configuration
menu it may not be necessary to reboot as this will
automatically follow after a load. However, if you
choose to reinitialize the interpreter system it is
recommended to reboot the system.
You can execute a reboot in case the interpreter system
needs a reboot by activating the reboot in Reset menu
item.
Options
Within the options menu of the interpreter system you
can alter the maximum number of booths, the maximum
number of desks per booth, the operating mode between
and within the booths.
A total of 28 interpreter booths can be connected to the
CONFIDEA CU and within each of these booths 8
desks can be placed. This means that up to 224
interpreter units can be used in a conference
configuration.
Maximum booths and desks
The maximum number of booths stipulates the number
of interpretation languages a conference system will
support. For example suppose you have a conference
room where English, French and German will be
spoken. You even have two interpreters for each
language. The only thing we have to do is configure the
system to have three booths and two desks.
The maximum number of desks defines the number of
desks each booth has. For example, if you set the
maximum number of desks to three, then this means
that each booth may have up to three desks.
Note: The number of interpreter languages supported by
your CONFIDEA CU does also depend upon the
licensing scheme you have bought. A standard system
can configure 2 languages.
Mode in and between booths
In the mode between booths three choices are available.
Mixed mode: more than one interpreter can translate to
the same language. The audio signals of the translation
are mixed and the interpreters are notified of this mixed
audio signal by the flashing of their microphone
indication led when they are translating simultaneously.
For example, booth 1 is translating the floor language to
French (on its A channel) and booth 2 starts to translate

to French (on its B channel). The delegates in the
conference room will hear the two translations mixed
through their headsets. The interpreters are notified of
this mixed audio signal by the flashing of the
microphone led and the red signal ring.
Override: any interpreter microphone in another booth
can override the current active microphone and become
active. The interpreter microphone that was just
overridden cannot return active again until the booth
responsible for the override deactivates its microphone.
Toggle Override: any interpreter microphone in another
booth can override the current active microphone and
become active. The interpreter microphone set to non-
active can return active for this translation by pressing
his microphone button again.
In the mode in booths only Mixed and Override is
available.
Mixed: multiple interpreters may simultaneously
translate to the same language. Whenever two
interpreters translate simultaneously they are notified by
the flashing microphone led and the flashing red signal
ring.
Override: this is similar to the Override mode of the
Mode between booths. The only difference here is that
the override happens on a per booth basis.
The interpreter menu - example Suppose we have the room configuration: a Wired
Confidea Digital Conference & Interpretation System
with a total of 2 languages spoken during a conference.
We will need up to 2 booths and 2 desks per booth for
dual interpreters to set up a correct configuration. You
have to have an additional license to be able to
configure more booths. This license can be purchased
trough your sales agent.
To be able to configure this we would need the
following hardware: one CONFIDEA CU and six
ID2500 interpreter desks. The number of conference
units depends on the conference room.
Let’s start setting up this system starting from a default
configuration. The setup will be described one step at a
time to make it easier to understand. If you feel that the
discussion of the setup is too detailed, feel free to skip
this section.

Loading the default settings
Start by loading the default settings for the interpreter
desks. We start from the main menu.
• Press ENTER, choose Interpretation Press ENTER
again, now choose Initialize Units. Press ENTER.
Now choose Load Defaults, press ENTER. Press
ENTER again to load the default values.
• Now that the defaults have to been loaded; we need
to reboot the system. Start from the main menu
again. Press ENTER, choose Interpretation. Press
ENTER again, now choose Reset. Press ENTER.
Press ENTER again to execute the reboot.
• The system has just been rebooted. If you go the
interpreter desks and look at their screen, then you
will notice that it will display Init Refused.
Congratulations, this means that we have just
rebooted our system to the default configuration.
Configuring the booths
Now that the system has been reset, we can start
configuring the settings of the booths on the
CONFIDEA CU. This has to be done before initializing
the interpreter desks and before altering the general
settings.
Suppose we want to make our booths responsible for
the following languages: booth 1 for English and booth
2 for Arabic. There are 2 possibilities to make the
necessary changes. You can start from a new
configuration or you can continue with the currently
configuration. Because we started from the default
configuration there will be no difference. Suppose we
choose to continue with the current configuration. Start
configuring each booth in the following sequence:
Alter the settings for the first booth. Start from the main
menu again. Press ENTER, choose Interpretation. Press
ENTER again, now choose Configuration. Press
ENTER. Scroll to Current and Press ENTER. Select the
booth number 1 and press ENTER.
Now we will alter the settings of booth 1. Turn the
wheel and select Language. Now press ENTER.
• Select your new language by turning the wheel. Our
choice for the language of booth 1 is English; so
select “ENG”. Press ENTER to confirm the choice
of our language.
102
NOTE: remember to press ENTER when you selected a
language, otherwise the language chosen will not be
confirmed.
• You have just configured the new language for
booth 1 in the CONFIDEA CU menu. These
changes have not yet been saved however. To save
these changes press EXIT. You should now go to the
screen depicted on the left. Turn the wheel to select
the Yes option and press ENTER to save. Our booth
configuration has just been saved.
• Suppose we wanted to change the auto-floor and B-
channel settings of our booth too. To do this, we
would have changed their settings before saving.
The B-channel may require some explanation
though. The B-channel menu on the central unit
displays numbers. These numbers reference the
other booths. Suppose you want booth 1 to have
Arabic as its default B channel. Arabic is the
language of booth 2. We will configure booth 2 in a
moment but suppose for know that booth 2 is
configured correctly. To set Arabic as the default B-
channel select B-channel = 2 and press ENTER.
Now save the booth as we have just configured the
settings.
• Configure booth 2 now by going through the steps
just described above. Set its language correctly to
Arabic (“ARA”) language. Configure its B-channel
and Auto-floor settings as you wish.
• After you configured and saved the booths, you also
need to save the global interpreter configuration as
Configuration 1 or Configuration 2. This can be
done by pressing the EXIT button in the Select
Booth menu. You should now go to the screen
depicted on the left. Turn the wheel to select the file
you want and press ENTER to save. Our
configuration has just been saved.
Altering the settings of each booth
Now that the booths has been correctly configured and
the room configuration has been saved as configuration
1 or configuration 2 we can start altering the settings for
each booth. The current default settings are the
following: number of booths is ‘2’, number of desks per
booth is ‘2’, mode between booths is Override and the
mode in booths is Override. As these default settings
will probably not match your needs, you can start
changing these settings at this moment. It is important

as Configuration 1Press ENTER to Save
103
to keep the correct order in the configuration procedure
to prevent unexpected errors. In this case the number
of booths and desk are the same as the default values so
it is not necessary to change this.
Configuring the interpreter units
Now that we are done configuring the booth on the
CONFIDEA CU, we will set up the interpreter desks so
that they will receive their information correctly.
• First, reboot the system. You may even check your
booth settings to see if they correspond to the
configuration we have set up in “Configuring the
booths
• ”. If everything was done correctly you will see that
these settings are correct.
• We are going to initialize the interpreter desks. Start
from the main menu again. Press ENTER, choose
Interpretation. Press ENTER again, now choose
Initialize Units and press ENTER.
We are now presented with a Full Init and an Add
Unit. The full init is used when we start with a fresh
system. The add option is used when you have a
configured a system and you want to add a new
booth or desk to you configuration. Enter the full
init mode. Press ENTER. You will notice that the
red signal rings of the interpreter desks will start
flashing. This means that they are in initialization
mode.
• Configure all the booths correctly. Once all booths
have been set correctly, go back to the central unit.
Ending the initialization mode at the central unit
• Back at the central unit. To stop the initialization
phase, press the ENTER button. If everything went
good you should see the screen depicted on the left
on an interpreter desk or a variant of that screen
depending on the booth and desk number of that
interpreter desk.
• This screen tells you that the interpreter unit has
been configured correctly. We can now start
working with the interpreter desks.
The “Add” init possibility
Suppose that we have an up and running system as the
one we just configured but you only have one
interpreter desk in booth 2 for the moment and you want
01 ENG 02 ARA00 00 00 00FLO FLO FLO FLO
104
to add an interpreter unit to this booth, so that it would
have 2 desks. You should then choose the Add Unit
menu item and press ENTER. The red signal rings of the
interpreter desks will now start flashing again and they
will all show the screen as depicted on the left. Ignore
the interpreter desks you already initialized and go
straight to the new interpreter unit. Set the booth of the
interpreter unit to 2 and the desk to 2 and confirm by
pressing the MICRO button. Now go back to the central
unit and press the ENTER button. You will notice that
the new interpreter desk has just been added to our
configuration.
Working with the interpreter units
• You can check the desk and booth number of an
interpreter desks by pressing the MUTE button,
keeping it pressed down and pressing the up or
down MENU buttons a couple of times.
• You cannot alter the A channel of an interpreter
desk at the interpreter desk. The A channel of a
booth is fixed.
• However, you can change the B channel of an
interpreter desk by keeping the B button at the right
of the screen pressed down and pressing up or down
simultaneously. This will cycle through all the
available languages. This means that an interpreter
can choose his own B channel.
• The loudspeaker channel can be changed by keeping
the LS CHAN. button pressed down and pressing the
up and down buttons simultaneously.
• Relay 1 can be changed by keeping the RELAY 1
button pressed down and pressing the up and down
buttons simultaneously.
• Relay 2 can be changed by keeping the RELAY 2
button pressed down and pressing the up and down
buttons simultaneously.
• Relay 3 can be changed by keeping the RELAY 3
button pressed down and pressing the up and down
buttons simultaneously.
• The green LEDs at the right of the screen indicate
which channel you have currently selected.
• An interpreter is currently translating the language
of an A or B channel when the red LED at the right
of the screen is lit.
105
The New function
Like already mentioned, you can begin a new
configuration by selecting the new menu. As soon as
you enter the new menu the current configuration will
be deleted. However, if you choose not to save the new
configuration, the previous configuration will be
restored.
After you made a new configuration you can alter the
maximum number of booths, the maximum number of
desks per booth, the operating mode between and within
the booths in the option menu.
Suppose we use currently a configuration that is saved
as Configuration 1 but we want to make another
configuration without deleting Configuration 1.
Immediately beginning with changing the options
needed for Configuration 2 will change the options for
Configuration 1 because after you altered the options a
general save follows which affects the current
configuration, in this case Configuration 1. To avoid
this, start with making a new configuration and save it
as Configuration 2. Afterwards, alter the necessary
options. Now you have two working configurations that
you can load at any time.
106
Auxiliary menu – overview
Usage
The auxiliary menu is used to configure all inputs and
outputs of the CONFIDEA CU. A number of external
devices, like a CD player or a microphone with
preamplifier, could be connected to the auxiliary input.
Other devices, like a recording unit, could be connected
to the auxiliary outputs. Also remote conferencing is
possible between two conference rooms.
The devices which will be connected to the central unit
differ from configuration to configuration. Therefore
the menu allows the auxiliary inputs and outputs to be
configured as needed.
The outputs
The system has 6 auxiliary outputs. The configuration
of the first auxiliary output, labeled AUX OUT 1 on the
back of the CONFIDEA CU, differs from the other
outputs as the channel of this auxiliary output is fixed.
The channel of this output is the floor channel. The
AUX OUT 1 is an XLR-3M output or the first output
that is contained within the D-sub connector. The
volume difference between AUX OUT 1 on the SUB-D
connector and the AUX OUT 1 on the XLR socket can
be adjusted by changing the VOLUME XLR in the
AUX OUT 1 menu item. By default there is no
difference. Also, it is possible to enable remote
conferencing. This will be discussed later in this
paragraph.
The other outputs, AUX OUT 2 – 3 – 4 – 5 – 6, are
contained within the D-sub connector. The pin
assignment of this connector has been discussed above.
Volume: The volume of the outputs can be configured
to the correct level. Just enter the Volume menu item
and set the appropriate level. The volume level will
change as the wheel is being turned. However, if you
want to save the settings so that the system always
booths with a certain volume level on that port, then do
not forget to press the ENTER button to save the new
value.
Channel: The audio signal of the interpretation channel
which an auxiliary output should output is configured
within the Channel menu item. The channels out of
which can be chosen depend on the licensing scheme of

your CONFIDEA CU. If you have a basic license, then
you are able to choose two channels.
Status: The status setting of the auxiliary output enables
or disables the selected output.
The headphone output channel on the front of the
central unit is the same as AUX OUT 6. The volume
difference between AUX OUT 6 on the SUB-D 15
connector and the AUX OUT on the headphone jack
can be adjusted by changing the Vol. Headphone in the
AUX OUT 6 menu item. By default there is no
difference.
The inputs
The system has two auxiliary inputs. These inputs are
labeled AUX IN 1 and AUX IN 2 at the back of the
CONFIDEA CU. The two inputs are both XLR-3F
connectors.
Level: The level of the inputs can be configured to the
correct level. Just enter the Level menu item and set the
appropriate level. The audio level will change as the
wheel is being turned. However, if you want to save the
settings so that the system always booths with a certain
volume level on that port, then do not forget to press the
ENTER button to save the new value.
Sensitivity: The sensitivity of the input channel can be
altered through this menu option. The sensitivity setting
has two options: LOW and HIGH.
Status: The status of the auxiliary input enables or
disables the selected input.

It is necessary to enable remote conferencing in the
AUX OUT 1 menu in each conference room to avoid
echoing. The screen you should go to is the screen
depicted on the left.
NOTE: keep in mind that for remote conferencing only
AUX IN 1 and AUX OUT 1 can be used.
External Equalizer
To avoid disturbing feedback or to equalize the audio
signals it is possible to interconnect external equipment
to the central unit. When such external equipment is
used, the external equalizer option should be set. When
setting the status to ON, the audio floor channel will be

disrupted in a way that all input signals (except AUX IN
1) will be directly routed to the AUX OUT 1. The signal
present on AUX IN 1 will be used as the new floor
channel. This way it is possible to use external audio
equipment like equalizers or feedback destroyers. The
schematic picture below summarizes this feature.
External Equalizer =OFF
External Equalizer = ON
Remark :
(Re)Setting the status for the external equalizer to
ON will change some other functions automatically:
o AUX IN 1 status = ON
o AUX IN 1 level = 18 (nominal)
o AUX IN 1 sensitivity = HIGH (+12 dB)
o AUX OUT 1 status = ON
o AUX OUT 1 volume = 18 (nominal)
o Remote conferencing = OFF
The settings can still be changed manually to desired
values.

Auxiliary menu - example
Recording or sending the audio signals of our translations to other devices
Suppose now that you have some additional audio
equipment installed which you will use to record
translations or which are used to sent the audio signal of
these translations to another device. For this you have to
configure the auxiliary outputs. The Aux Out 1 audio
signal is always the floor channel signal; you cannot
change this. However, the Aux Out 2, Aux Out 3, Aux
Out 4, Aux Out 5 and Aux Out 6 audio signal can be
changed. We will explain how to set the
(audio/interpreter) channel which should be sent to
these outputs on the central unit.
• Start from the main menu, and press ENTER. Now
choose Aux-In/Out and press ENTER. Select Aux
Out 1 and press ENTER. You can change the
volume and the status of the Aux Out 1 output
signal. The volume choice is self-explanatory and
the status menu has two options: On and Off. Set the
status to On if you want to enable the signal sent
out.
• The other output menu choices contain the same
volume and status options. In addition to these
options a channel option is also present. What does
the channel stand for? Recall that we just configured
our interpreter system as explained above. English is
on channel (booth) 1 and Arabic on channel (booth)
2. The numbers describe the booths in our system.
You can therefore set which audio signal you want
to send to your output.
111
System menu – overview
Usage
The system menu contains system wide monitoring and
configuration options. Five different options are
present:
Diagnostics
An overview of the conference terminal strings
connected to the central unit is provided in this menu. It
is also what you’ll see on the main screen (with the
volume bar). Next to this overview you can also check
if there are communications errors on specific ports
from within the Port Errors menu item. The symbol
representing the error will then appear on that port.
Explanation of the symbols:
: means that there is a string of conference terminals
connected to the port described under the symbol.
: is the opposite of the above symbol. It stands for
an unconnected port or a wrongly connected string of
conference terminals. (No string or a wrongly connected
string of conference terminals is connected to that port
number). In the case you have a string of conference
terminals connected to the central unit and the symbol
remains, then check if you have connected the IN port
of the conference terminal to one of the six ports.
: is the symbol representing the communications
error. It will only appear on a port to which a string of
conference terminals is connected as no
communications errors can occur on an unconnected
port. Pressing ENTER will reset the error indicator.
Camera control
If you ordered a Wired Confidea Digital Conference &
Interpretation System with camera control, then this
option is enabled through your licensing scheme.
Otherwise you cannot alter the settings of this option.
More information can be found in appendix A.
Control Panel
The optional control panel must be enabled through this
menu item. A control panel is a miniature physical

Troubleshooting
If problems occur …
Replacing a fuse
If the fuse of a central unit has blown, the subsequent
delegate units cannot be powered. To replace the fuse of
a central unit, proceed as follows:
• Use a screwdriver to carefully loosen the fuse holder
and pull it out completely.
• Remove the fuse. This is the faulty fuse.
• Now replace the fuse.
The specifications for the replacement fuse are shown
above the fuse holder.
Tips for troubleshooting
Delegate unit does not work
Check if the system cable between the central unit and
the delegate unit is defective or if the system cable has
been pulled out.
Check if the central unit is connected to the mains and if
they are turned on.
No microphones except the chairman microphone can be set active
Check the TMS submenu on the central unit. Check if
the maximum number of microphones that are allowed
to be up is not set to zero. If this is the case, alter this
value and set it to at least 1.
116
Maintenance and care Use a damp cloth for cleaning the components of the
conference system from time to time. Never use
solvent-containing cleansers, as these could damage the
surfaces of the components.
117
Appendix A: Camera Control Protocol
Overview The Wired Confidea Digital Conference &
Interpretation System supports a camera control. The
commands which the camera control should understand
will be described shortly.
The camera control must be connected to the
CONFIDEA CU through a RS232 connection. The
appropriate port to use on the CONFIDEA CU is
COM2. The communications port COM2 operates at a
speed of 19200 bits per second.
A complete overview of the settings of the
communications port for the camera control:
Bits per second: 19200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Note however that in order to activate the camera
control on the central unit you have to own a license
which entitles you to.
118
Commands
All commands sent by the CONFIDEA CU start with a
‘%’ sign. The last character is a character which states
the end of the transmission. Just before the end of
transmission character, there are four characters within
the command sent to the camera control which account
for the CRC checksum. The CRC checksum is in
uppercase hexadecimal form while all other numbers
are in decimal form.
The protocol is described as follows:
STX ‘%’ data CRC ETX
With:
STX = start transmit char (0x25 = ‘%’)
ETX = end transmit char (0x0D)
CRC = 16 bit sum of the ASCII characters
between STX and CRC
We will adopt a certain notation to explain the messages
sent. All separate entities in a message are represented
between curly brackets. If the contents of such an entity
is also between quotes (‘ ‘) then this means that this is a
literal string. Otherwise it describes the logical entity. A
logical entity will also contain a number between
brackets. This number states how many characters the
entity will exist of. If the subtext 1+ is attached to the
entity between curly brackets, then this means that one
or more occurrences of this entity may occur.
Maybe this notation seems a little hard to comprehend
at first, but some examples should clarify them.
Whenever a microphone of a delegate or the
microphone of the president is activated, then a
command is sent to the camera control. Whenever an
active microphone is deactivated, another command is
sent to the camera control.
• The microphone of the president is activated:
‘%’‘P’Microphone number (4) CRC (4)
• The microphone of the president is deactivated:
‘%’‘p’Microphone number (4) CRC (4)
• The microphone of a delegate is activated:
‘%’‘M’Microphone number (4) CRC (4)
• The microphone of a delegate is deactivated:
‘%’‘m’Microphone number (4) CRC (4)
119
The remaining commands are control commands.
• First microphone has been activated and the camera
control should become active.
‘%’‘1’‘R’‘00’CRC (4)
• All active microphones are deactivated and the
camera control should reset itself to a neutral
starting position.
‘%’ ‘1’‘r’‘00’CRC (4)
• At a time-interval of around 5 seconds a
synchronization message is sent to the camera
control. The message contains all the numbers of the
active microphones or the number 0 to stipulate that
there are no microphones active.
‘%’‘S’Microphone Number (4)1+CRC (4)
• All active microphones are deactivated
simultaneously.
‘%’‘V’‘0000’CRC (4)
Examples
If the president microphone is activated, and the
president microphone has the number ‘0001’ then the
following message is sent: %P00010111
When the president microphone is deactivated, then the
following message is sent: %p00010131
If a delegate microphone is activated, and that delegate
microphone has the number ‘0003’ then the following
message is sent: %M00030110
When the delegate microphone is deactivated, then the
following message is sent: %m00030130
Suppose now that the delegate microphone with number
‘0003’ is active. On a synchronization check the
synchronization message will look like this:
%S00030116
Suppose now that the delegate microphones with
number ‘0002’ and ‘0004’ are also active. On a
synchronization check the synchronization message will
look like this: %000300020004029C
When no microphones are active, then the following
synchronization will be received: %S00000113
When the camera control system should reset itself to
its start position, then the following message will be
received: %1r000052
120
When all microphones are deactivated simultaneously,
then the following message is received: %V00000116
121
Appendix B: Control Panel Protocol
Overview The Wired Confidea Digital Conference &
Interpretation System supports a control panel such as
AMX, Crestron (ie Dataton, …). The commands which
the control panel should understand will be described
shortly.
The control panel must be connected to the CONFIDEA
CU through a RS232 connection. The appropriate port
to use on the CONFIDEA CU is COM2. The
communications port COM2 operates at a speed of
19200 bits per second.
A complete overview of the settings of the
communications port for the control panel:
Bits per second: 19200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
REMARK : When TCS 2500 Application
Programming Interface is used to manage the Wired
Confidea microphone system and voting system , then
the appropriate port to use on the CONFIDEA CU is
COM3.

Commands
All commands sent by the CONFIDEA CU start with a
‘%’ sign. The last character is a character which states
the end of the transmission. Just before the end of
transmission character, there are four characters within
the command sent to the control panel which account
for the CRC checksum. The CRC checksum is in
uppercase hexadecimal form while all other numbers
are in decimal form.
The protocol is described as follows:
STX ‘%’ data CRC ETX
With:
STX = start transmit char (0x25 = ‘%’)
ETX = end transmit char (0x0D)
CRC = 16 bit sum of the ASCII characters
between STX and CRC
We will adopt a certain notation to explain the messages
sent. All separate entities in a message are represented
between curly brackets. If the contents of such an entity
is also between quotes (‘ ‘) then this means that this is a
literal string. Otherwise it describes the logical entity. A
logical entity will also contain a number between
brackets. This number states how many characters the
entity will exist of. If the subtext 1+ is attached to the
entity between curly brackets, then this means that one
or more occurrences of this entity may occur.
Maybe this notation seems a little hard to comprehend
at first, but some examples should clarify them.
Whenever a microphone of a delegate or the
microphone of the president is activated, then a
command is sent to the control panel. Whenever an
active microphone is deactivated, another command is
sent to the control panel. This is also valid when a
microphone goes into request.
The control panel is also able to send commands to the
central unit. One command is sent to activate/deactivate
a microphone. There is also a command that can be sent
to the central unit if you want to reboot the control
panel. Also the test generator can be activated or
deactivated. Other commands allows you to alter the
volume and conference mode.
We will divide the discussion of the commands into two
categories. The first category describes the commands
coming from the central unit and going to the control
123
panel and the second category describes the commands
coming from the central unit and going to the control
panel.
The Commands sent by the central unit and received by
the control panel:
• A microphone is activated:
‘%’‘1’‘L’Microphone number (4) CRC
(4)
• A microphone is deactivated:
‘%’‘1’‘l’Microphone number (4) CRC
(4)
• A microphone goes into request:
‘%’‘1’‘D’Microphone number (4) CRC
(4)
• All microphone should be reset:
‘%’‘E’‘00’ CRC (4)
• Function key pressed on president unit
‘%’‘[’‘F’Menu ID (2)Function
key(2)Action ID (3)CRC (4)
When configured, the chairmen units can initiate an
action by selecting a user defined menu and pressing
a function key.
The “menu ID” indicates the selected user menu on
the delegate unit:
Name ID
MENU_FUNCTION_KEYS_1 4
MENU_FUNCTION_KEYS_2 5
MENU_FUNCTION_KEYS_3 6
MENU_FUNCTION_KEYS_4 7
The “function key” corresponds to the pushed
button on the chairman unit:
124
Function key ID
Vote button 1 0
Vote button 2 1
Vote button 3 2
Vote button 4 3
Vote button 5 4
The action that is assigned to the function key is
provided in the “Action ID”
The commands sent by the control panel and received
by the central unit:
• Activate/deactivate a microphone with number … :
‘%’‘1’‘T’Microphone number (4)CRC

Any other commands sent over the serial channel from
the central unit to the control panel should be ignored.
Examples
If a microphone is activated, and the microphone has
the number ‘0001’ then the following message is sent to
the control panel from the central unit: %1L0001013E
If the same microphone is deactivated, then the
following message is sent to the control panel from the
central unit: %1l0001015E
126
If the microphone with number ‘0002’ goes into request
mode, then the following message is sent to the control
panel from the central unit: %1D00020137
When all microphones should be turned of, then the
following command is sent to the control panel from the
central unit: %1E0000D6
When the control panel wants the central unit to activate
a microphone, for instance the microphone with number
‘0002’, then the following command is sent:
%1T00020147
When the control panel wants to restart the control
panel and wants to receive the correct information about
the active microphones and the microphones on request,
then the following command is sent to the central unit:
%1V0087
When the control panel wants to change the conference
mode then the following command is sent to the central
unit: %1U0400EA
When the control panel wants to mute the loudspeaker
of all units the following command is sent to the central
unit: %1X00060606021B.
The default volume setting can be set by sending the
following command to the central unit:
%1X060606060221

Appendix C: Analog Output Device (AOP) manual
Overview The AOP2500 unit allows connecting of analog
equipment (such as IR modulators, sound reinforcement
amplifiers, analog cassette recorders etc…) to the
CONFIDEA CU Digital central unit. It is equipped with
9 D/A converters and outputs the floor language
channel and up till 8 translated channels. Power is taken
from the CONFIDEA CU.
Channel 0 is always the floor language. Channel 1 can
only be configured freely by rotary switch programming
(internal). Channels 2 to 8 are the next consecutive
channels of channel 1.
Three LED’s are on the front: one to indicate power,
one to indicate sync and one to indicate that modulation
is present at the floor channel.

Configuration
• Channel 0 (CH0) is always the floor language.
• Channel 1 (CH1) is the reference channel and is
only by hardware configurable. The other channels
(CH2 to CH8) are the next consecutive channels of
channel 1.
• The configuration of channel 1 depends on the
Rotary switch and the DIP switches. The value of
channel 1 is the sum of the values of the Rotary
switch and the DIP switches.
• The value of the Rotary switch is marked on the
switch.
• The value of the DIP switches is 0 if both switches
are off, in all other cases is the value 16.

Remote Control
There is a voltage free contact that is closed when a
microphone is active and that is open when no
microphone is active. The CONFIDEA CU controls this
voltage free contact. At the backside of the unit, the
Phoenix connector is numbered from left to right (non
removable connector).
Maximum load
current(continuous) = 1A
Maximum load current
(continuous) = 1.8 A
Maximum load voltage =

Appendix E: Connecting Confidea Access Point to CONFIDEA CU
Overview When Confidea system is used in “TCS2500 coupled “
mode , the Confidea Access Point needs to be connected
to one of the PORT1-6 sockets of the CONFIDEA CU
central , just as any other delegate unit
Via this connection , the communication and audio
signals between Confidea Access Point and
CONFIDEA CU are handled.
This connection also provides DC power supply from
the CONFIDEA CU to the Confidea Access point. So
no separate 220Vac/24Vdc adapter needed to feed the
Confidea Access Point, although it is still allowed to use
one.
Initialisation of Confidea WDU’s is done just as any
other type of delegate unit
