Interconnection of units
Cable 3a: 2nd Control Unit - Transceiver Unit
If a 2nd control unit is installed, this can be done by splitting and extending the CAN bus, using e.g.
the 406208A control unit box.
Note that the CAN bus must be terminated with 120 Ohm in each end of the bus (not in the middle!).
The transceiver unit is terminated per default. Move Jumper W402 placed just inside the transceiver
unit, if termination is not needed in the place the transceiver is installed. In this case, termination
must added at both control units.
