The TZX08 is also equipped with 6 common IR outputs useful for controlling up to 6 machines from all areas at the same time.

As already mentioned, transmission of the IR signal permits choice of the source and its volume from each zones, and control of a unit located in another environment usually the machine room, where the TZX08 is also located, from an area where the Y/C and audio outputs of the TZX08 arrive, using an IR remote control

To di this, you need:

an external amplified IR receiver normally installed on a wall and connected to the IR ZONES terminals (RECEIVERS) of the TZX08.

an IR emitter which will be connected to the IR SOURCES jack (EMITTERS) of the TZX08

The IR emitter will be positioned on the front of the appliance to be controlled (DVD player, Satellite etc.).

Usually, the IR emitter is fitted with a 1.5 meter cable, long enough to connect to the unit to be controlled.

However, in some cases, the distance between one of the zones to be energized and the TZX08 unit may be some hundreds of meters. In this case, extension of the cable of the IR receiver may be a problem and there is also a risk of downgrading of the video signal.

It may be advisable to insert a pair of TPA110 IRT / TPA110 IRR products in the system in order to carry the video, audio and IR signals at a distance using the CAT5 cable (4 twisted pairs). In this case not use the Y/C signals, but connect on yellow RCA sockets (OTUPUT 1÷4), the outputs composite signal.

For other information on connection of IR devices, refer to paragraph 4.3

TYPICAL SYSTEM

A typical system using the TZX08 is represented schematically in the drawing below.

As can be seen in the drawing above, the sources usually involved in this type of system, of which the TZX08 is the core, are:

DVD Player, Laser disc player, CD player, Decoder satellite, VCR, TV tuner, Security cameras

The VIDEO and AUDIO PREVIEW output is a composite video output with associated stereo audio. It can be connected to a local monitor and to two active loudspeakers. The TZX08 is also fitted with a small built-in loudspeaker which often avoids the need for external active loudspeakers. Audio monitoring is also present on a 6.3mm headset jack which, if inserted, excludes the built-in loudspeaker.

The VIDEO and AUDIO PREVIEW output is useful for displaying and listening to a number of sources without these forming part of a switching.(see paragraph 5.1)

2.0 POWER SUPPLYBefore powering the unit, check that the MAINS VOLTAGE SELECTOR is in the position corresponding to the power supply available in your country.

You can choose between 110Vac and 230Vac.

Insert usual drawing of the back of the unit with the mains selector and wall plug.

The panel plug is complete with fuse-holder for 5X20 fuses.

If the fuse blows, replace with a fuse with the same rating as specified on the back of the unit. (T 0.5 A).

WARNING

All maintenance operations must be carried out by qualified personnel only who must be informed

of the risks of electric shock. Do not open the cover of the unit without first of all removing the

electric cable.

For European countries, the TZX08 must be powered at 230 Vac 50Hz using the cable provided. The outlet of the cable must be inserted in the related panel plug to the left at the back of the unit.

In some countries, regardless of the power voltage available, the plug of the cable must be replaced to adapt it to local standards.

The wires are identified according to the following coding:

- Brown PHASE (Identified with the letter L, may be red)

- Blue NEUTRAL (Identified with the letter N, may be black)

- Yellow/Green GROUND (Identified with the letter E, may be green)

WARNING

A ground connection is mandatory.

The MAINS VOLTAGE SELECTOR is factory set to 230Vac.

Each audio output is equipped with VCA to permit adjustment of the sound level for each zone.

The three types of switching, video, audio and IR, and also audio volume, are controlled by keyboard via the display and all three can be performed concurrently or only one or two leaving the others unchanged.

Note that the IR connection is also single-directional but follows the opposite direction to normal video and audio switching; that is to say, at system level, the IR receivers that are the signal sources will be positioned where the video and audio destinations are positioned. The IR emitters, which are the so-called destinations, will be positioned where the video and audio sources are present. Therefore, we will have 7 IR sources for 8 IR destinations. (Note the direction of the arrows on the Typical System drawing).

As opposed to the matrix concept according to which a single input at a time accesses each output, as regards IR the concept is that several inputs can access each output at the same time.

An example is provided below:

- Source 1 (DVD) switched on all 7 ZONES (outputs)

- The 7 IR receivers relating to each output must access and command the IR emitter located beside source 1 (DVD).

Obviously, if several users want to access a source at the same time from several ZONES, the emitter in output will not emit correctly and will not be understood by the unit for which the command is intended.

There is no conflit when from each zones, through the TZX08 IR control, the user wants to choice the source and adjust the volume. In this case each zone operates only on itself.

The TZX08 is also fitted with 6 "COMMON" IR outputs obtained from the logical OR of the 7 sources. The 6 "COMMON" outputs are all the same. These "COMMON" outputs are useful for controlling one or more units from all 7 zones at the same time regardless of machine status. (In the example in drawing above, Typical System, the 2 common outputs drive two security cameras).

The unit is equipped with one IR remote control furnished with the unit. Others IR control for the zones, must be purchased a part (optional). For use of this, refer to paragraph 6.0

The unit can be driven via RS232. For those who intend to write dedicated connection software, the data exchange protocol is described in paragraph 7.0.

When installing the IR receiver, always comply with the manufacturer's instructions regarding:

-Sensitivity

-Exposure to environmental and sunlight

-Settings and calibration

WARNING

Amplified IR receivers must be used

When selecting the IR receiver, the user must pay particular attention to the operating frequency of the remote control whose signal is remotized.

Most remote controls operate at low frequencies (37 KHz) but some manufacturers (Bang & Olufsen, Kenwood, Pioneer) use remote controls with carrier frequencies of up to 1,125MHz.

WARNING

Make sure you buy an IR receiver that is compatible with the frequency of the remote control.

The TZX08 is compatible with frequencies of up to 1.2MHz

The IR receivers available on the market are of the 3-wire type:

Positive (+), GND (0 Volts) and SIGNAL.

Connect the IR receiver to the terminals of the TZX08 unit marked IR ZONES (RECEIVERS) +12, GND and SIG. If the cable leading out of the receiver is fitted with a 3.5 mm stereo jack, cut the cable and identify the three wires to be connected to IR ZONES +12, GND and SIG terminals of the TZX08 unit.

For the pin-out of the receiver, refer to its user manual.

Most of the receivers on the market have a power SIGNAL output, i.e. able to drive an IR transmitter directly. In this case, no setting is required on the TZX08 unit as it is factory set for this type of interface.

If the IR receiver has a SIGNAL output at TTL level, the TZX08 unit must be set as described in paragraph 3.0 SETTINGS

WARNINGIf available, use of IR receivers

with TTL output is recommended as they consume less and are

less expensive

4.2.2 Connect the inputs of the audio destinations present in the 7 zones (Amplifiers, recorders, RF modulators, etc.) to the vertical RCA sockets called AUDIO ZONES and numbered from 1 to 7.

5.0 LOCAL CONTROL

The TZX08 incorporates a console from which a series of commands and settings can be sent to the unit. These are:

- Video, audio, IR and volume SWITCH COMMANDS for each zone.

- Mnemonic NAME SETTINGS for the 8 sources, 7 zones and 8 storable configurations.

- SAVE or RECALL CONFIGURATION.

All of these commands and switching functions are executed with the use of the display unit.

The display unit usually shows the status of a zone by indicating the video and audio inputs, the audio volume setting and the source towards which the IR receiver is directed. (On one zone the video and audio usually come from the same source and the IR receiver is directed towards that source).

Zone display (Example)

5.1 SWITCH COMMANDS

Switch commands are set and executed on a specific zone. Use the SCROLL pushbutton to view the required zone on the display unit. There are 7 zones that can be used, the eighth is the PREVIEW page.

The following are used to control switching in each zone:

PROG to enter programming mode.

SCROLL to select the line to be programmed (in line 3, the audio line, there

are two programme settings, volume and source).

4.4 Use the POWER ON switch to power on the TZX08.

The display lights up and shows the status of zone 1.

WARNING

At power-on the TZX08 is set according to the last RECALL received; otherwise, it connects input 1 on all the outputs.

If you want the TZX08 to be set to a pre-established (default) configuration at power-on, proceed as follows:

-In the NAME SETTING menu, set the DEFAULT name of a configuration

-Configure the TZX08

-Access the SAVE/RECALL menu

-Save the status of the TZX08 with the DEFAULT name


-Recall the DEFAULT configuration

From this moment, at each power-on, the TZX08 will be set to the configuration set by the customer.

WARNING

Subsequent recalls from keypad or computer modify the default configuration which will match the last preset recalled.

7.11 Video and audio preview command

The TZX08 connects the video and audio inputs on the preview output.


bXX followed by CR where: b is the character Hex 62

XX is video and audio input (from 01 to 08)

Example: To switch the video and audio signals of input 1 on the preview outputs, the host will send the following sequence on line: 62 30 31 0D




7.12 Setting of audio level on a zone

The TZX08 can modify the audio level of the 7 outputs (zones).


lXXYY followed by CR where: l ( like in "love") is the character Hex 6C

XX is the output on which to set the audio level

YY is the audio level required (from 00 to 99)

Level 00 (30 30 on line) corresponds to MUTE; level 99 (39 39 on line) corresponds to the maximum level of 99% (0dB).

Correspondence between the hexadecimal value and the audio level and the ASCII characters to be sent on line:

Example:

To set the audio level to 09 (9%) on output 6, the host will send the following sequence: 6C 30 36 30 39 0D; to set the maximum audio level (99%) on output 4, the host will send the following sequence: 6C 30 34 39 39 0D;




7.8 Recall of a preset

A previously stored preset can be activated. The host must send the following sequence:

RNN followed by CR where: R is the character Hex 52


Example: If the preset identified by the number 5 is to be recalled, the host will send the following sequence on line: 52 30 35 0D




Remember that preset 7 can also be recalled from the keypad.

7.9 Video preview command

The TZX08 connects a video input to the preview output.


vXX followed by CR where: v is the character Hex 76

XX is the video input from 01 to 04)

Example: To switch video input 4 to the preview output, the host will send the following sequence on line: 76 30 34 0D




7.10 Audio preview command
