6.0 Network Burden

The software selectable Network Burden can only be enabled on a unit with an

address of 001. The Burden can be enabled from the ‘Global Tab’ within the GUI for the

Network Interface, which is the same as the PC Interface Module.

Caution: The GUI software is designed to prevent accidental selection of the Burden.

The following steps are required to correctly enable the Network Burden from the GUI:

1. Select the Network Burden check box (cross inside box for ON),

2. Click OK button,

3. Select ‘Save to Network’ and/or ‘Save to Database’,

4. Click OK button, then,

5. Repeat steps 3 and 4 within 20 seconds, to save your selection.

To disable the Network Burden the same process applies except the Burden selection

check box is cleared (remove cross). The Network Burden will be automatically

disabled if the Unit Address is changed from 001.

7.0 Connection to the C-Bus Network

Installation of the Network Interface on to a C-Bus Network requires connection to the

unshielded twisted pair C-Bus Network Cable. The illustration below shows the

recommended technique for cable termination giving the best electrical performance. It

is recommended that Category 5 data cable is used, Clipsal catalogue no. 5005C305B.

RJ Pin C-Bus Connection Colour

1 Remote ON * Green/White

2 Remote ON * Green

3 C-Bus Neg (-) Orange/White

4 C-Bus Pos (+) Blue

5 C-Bus Neg (-) Blue/White

6 C-Bus Pos (+) Orange

7 Remote OFF * Brown/White

8 Remote OFF * Brown

* The Network Interface does not have Remote Override (ON/OFF) functions,

however correct connections must be maintained for these services across the C-Bus

Network. They are looped between the two C-Bus connections on the unit.

Note the mutual twist of solid and dotted conductors of opposing coloured conductors.

This ensures a good electrical termination, with favourable common mode noise

characteristics.

NOTE: Rubber bungs are supplied (3 off) for unused RJ45 connectors, to stop foreign

bodies from entering the units.
