Requirements: Accessibility to the rear cover of the DDC.
To connect a CAN BUS cable to a DDC:
1. Position the jumpers on the DDC according to the type of node being configured: If
necessary, open the rear cover of the DDC by loosening the 4 screws; after the
jumpers have been correctly configured, close the cover and tighten the 4 screws.
The jumper positions are shown in the two figures below:
If the DDC is an intermediate node on the network (there are 6 wires attached to the
orange connector): position the jumpers on the DDC as shown in Figure 30: OPEN.
Figure 30 β Connecting 2 CAN BUS cables to the DDC: THE DDC IS AN INTERMEDIATE NODE. Note the position
of the wires of the CAN BUS cable and the jumpers: OPEN
If the DDC is a terminal node on the network (there are 3 wires attached to the orange
connector): position the jumpers on the DDC as shown in Figure 31: CLOSED.
Figure 31 β Connection of 1 CAN BUS cable to the DDC: THE DDC IS A TERMINAL NODE. Note the position of the
wires of the CAN BUS cable and the jumpers: CLOSED
2. Remove the orange CAN BUS connector from its bag.
3. Cut the ideal length of cable for the installation so that it is not subject to bending.
