CAN Bus Cabling

The CAN Bus is integrated in the Site Controller. There is one CAN Bus in the cabinet. The CAN Bus
can be connected to the Site Controllers, PSUs, DPMs, and ATCCs.
NOTICE: The pinout has been designed so that an accidental mis-connection by one or into
one of the other RJ45 connectors (Ethernet, Service port, or E1) does not damage any circuitry.
The CAN Bus is a 120 twisted line with termination at the ends.
