Operating Parameter:
Maximum total length of Cat 5 UTP cable on any one C-Bus network –
1 km.
Maximum total number of standard C-Bus units on any one network –
100.
Each standard C-Bus unit requires 18 mA @ 36VDC to operate
correctly. Some C-Bus units, eg. 5500PC (PC Interface) requires 32
mA. Some C-Bus units, eg. L5508D1A (8 Channel Dimmer) are self
powering and do not take current from the 36VDC Bus. Check product
specification for details.
C-Bus System Design Criteria
More than one C-Bus power supply can be connected to a C-Bus
network to provide sufficient power to the C-Bus units, the C-Bus
power supplies will share the load evenly. Maximum total power
supplies allowed: 2,000 mA (2A).
eg: 5500PS (350mA each) Maximum No. 5 (1,750mA)
L5508D1A (200mA each) Maximum No. 10 (2,000mA)
L5512RVF (200mA each) Maximum No. 10 (2,000mA)
L5104D5A (60mA each) Maximum No. 30 (1,800mA)
Any combination of power supply units is allowed as long as the
total power available is 2,000mA or less.
C-Bus System Design Criteria
C-Bus System Design Criteria
Each C-Bus network requires one network burden only. This network
burden can be found on the following units:
5500PC PC Interface (software selectable)
5222CB/2 HomeMinder C-Bus Interface (hardware selectable)
L5508D1A 8 Channel DIN Dimmer (software selectable)

C-Bus System Design Criteria
C-Bus System Design Criteria
Maximum number of networks connected in series to the local
network: 7 (ie. using 6 Network Bridges). More networks can be
achieved by the combination of star and series wiring
altogether.
C-Bus System Design Criteria
C-Bus power supply units (including DIN and PRO units) may be
connected to different phases.
Individual Relay channels may be connected to different phases. On
all Din Rail Dimmers, the 240V supply to the units power supply and
the 240V supply to the output channels must be on the same
phase.
The isolation between the 240Vac mains circuitry and the 36VDC
C-Bus circuitry is greater than 3.5kV. This is achieved using
double wound transformers and opto isolators. This means the C-Bus
wiring, connections and circuitry can be considered Safety Extra
Low Voltage.
C-Bus System Design Criteria
The C-Bus Network Connection is fulfilled by the following wiring
configuration :
RJ Pin
C-Bus Connection
C-Bus Wiring:
The C-Bus system should be wired using Category 5 (Cat 5)
Unshielded Twisted Pair (UTP).
The most common form that this wire comes in is four twisted pairs.
The four twisted pairs are colour coded.
Orange + Blue:
C-Bus System Design Criteria
Which wire to use
To maintain noise immunity it is required that the twist that
exists between pairs is maintained when they are connected to the
+ve and –ve C-Bus terminals.
C-Bus System Design Criteria
Connecting the Cat 5 cable to the Screw Terminal
Cat 5 cable is most commonly single strand 0.2 sq mm copper in each
conductor.
Care must be taken when twisting the conductors together that the
wire does not break.
Care must also be taken to ensure all wires are secure.
Conductors Twisted Together
Maximum 2 conductors.
YES
Connecting the Cat 5 cable to the Screw Terminal
By using a small ‘boot lace’ or ferrule crimp up to 4 CAT 5
conductors can be securely held.
Depending on the size of crimp used more than one crimp may be held
in a terminal.
Conductors Crimped Together
Maximum 4 conductors.
Local Toggle Buttons
The DIN and PRO series C-Bus outputs are equipped with Local Toggle
control for each output channel. These control buttons will operate
as long as mains is connected to the DIN unit. They do not require
the C-bus connection to be wired in. Pressing the local toggle
control button will alternately turn the load wired to the
respective channel On and Off. This function allows you to check
that the mains wiring is correct and that the loads switched by
each channel are correct.
Quick Toggle Control
When your PC is connected to the C-Bus network there is the
facility to turn a Group Address or Area Address on and off using
mouse button commands. This allows you to check that the correct
Group or Area Address has been assigned to a load.
C-Bus System Design Criteria
C-Bus Calculator
All the C-Bus units that are to be used on a project can be
programmed in and the C-Bus calculator checks that the requirements
for maximum number of units, adequate number of power supplies,
clock generating units, etc have been allowed for.
C-Bus Network Analyser 5000NA
This product is temporarily connected to a C-Bus network. The
network analyser will indicate the status of the C-Bus power
supply, network burden, system clock and acceptable cable
length.
C-Bus System Design Criteria
C-Bus MMI Status Report
The MMI (Multipoint to Multipoint Instruction) can be used to
question a C-Bus Network. It is accessed by opening the C-Bus
software, and clicking on the Network Status Report Button in the
tool bar. The MMI provides a display which is a quick means of
checking the units on a C-Bus Network, as well as displaying the
state of group addresses. The status can be requested manually by
pressing the Status button, or automatically by clicking on the
Auto button.
C-Bus Diagnostic Utility
The C-Bus Diagnostics Software allows the user to set the mode of a
C-Bus Serial Interface and send command strings to C-Bus and to
observe the data traffic. Actually, it can be applied for C-Bus
Monitoring & Controlling Event Log.
C-Bus System Design Criteria
Fact to Know
All C-Bus units leave the factory with a default Unit Address
(identity) of ‘255’. Before it is connected to a C-Bus system a new
unique Unit Address must be assigned.

Length Limitations of Ethernet Networks
10Base-T Ethernet networks have important length limits. Exceeding
these lengths will result in packet loss and network failures,
resulting in an unreliable system.
Here are some simple rules you can apply to keep your network
operating correctly :
10Base-T cables must be less than 100 meters long (when measured
from device to Hub, or Hub to Hub);
There must be no more than 3 Hubs between the far ends of the
networks;
10Base-FL Fiber-Optic segments must be less than 1000m long.

T&C and Trouble Shooting
Basic Trouble Shooting
Normally, the C-Bus System may involve the following failure
problems :
36VDC or 220VAC supply is not stable or even failed
System Clock is missing
Network Burden is missing
Component is failed
The engineer should firstly verify the system design status such as
the Operating Voltage & Current, total Installed Units in a
network, the Cable length and then the System clock & Network
burden. The following tools are generally employed in our
trouble-shooting work.
T&C and Trouble Shooting
Using the C-Bus Calculator
The C-Bus Calculator can automatically determine how much current
is being used, how many power supplies are needed and if network
burden is needed. It also monitors how many C-Bus units are on the
network.
T&C and Trouble Shooting
Using the C-Bus Installation Software
The MMI (Multipoint to Multipoint Instruction) can be used to
question a C-Bus Network by clicking on the Network Status Report
Button in the tool bar as below.
There are two basic Status Types that the MMI views. They are
:
Installation MMI
Application MMI
Installation MMI
The Installation MMI determines the presence of a C-Bus unit at a
particular unit address, where the Application MMI determines the
status of a group address on a particular application. The status
can be requested manually by pressing the Status button, or
automatically by clicking on the Auto button.
T&C and Trouble Shooting
Installation MMI
If a MMI report returns an error state it will display a unit
address or group address highlighted red. This red number indicates
the address of where the error lies a shown below.
T&C and Trouble Shooting
Installation MMI
Once the MMI detects an error, it will try to determine the exact
cause of it. By clicking on the ‘Error Status’ tab, the nature of
the error can be view as shown below.
03 – Two or more units share the address
T&C and Trouble Shooting
Using a Multimeter
Apply the Voltmeter to check the AC mains voltage and the C-Bus
operating voltage.
Apply the Ohmmeter to check the Short circuit and Open circuit on a
C-Bus network. The symptoms of a short on a C-Bus Network would
be:
All input LED’s and C-Bus indicators on output units are off.
The C-Bus Voltage is 0V
T&C and Trouble Shooting
Using a Multimeter
Incorrect C-Bus pairs used on installation.
Loose terminations shorting to another terminal on
installation.
Moisture partially shorting two terminals.
Foreign objects shorting C-Bus terminals.
The two simplest ways of checking for a short circuit on a C-Bus
Network are to use a Multimeter on the Resistance and Audible
Continuity Test settings.
T&C and Trouble Shooting
Using a Multimeter
An Open circuit condition is another symptom of an incorrect
installation. An open circuit may cause units on a particular side
of the C-Bus Network not to operate. It is usually found by using
successive approximation.
Start testing the network at the half way point. Find the side that
is not getting receiving C-Bus commands and continue this process
until the open circuit had been found.
T&C and Trouble Shooting
Using the LED Indicators on C-Bus Output Unit
In general, the common system faults can also be found out through
the displayed status of the indicators as shown below:
