The CAN Bus is integrated in the Site Controller. There is one CAN Bus in the cabinets. The CAN
Bus can be connected to the Site Controllers, PSUs, DPMs, and ATCCs.
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 Ω twisted line with termination at the ends.
MTS 2 CAN Bus Cabling
The Site Controller contains the internal termination in one end of the CAN Bus, and the last
Duplexer in the CAN Bus has a terminator in one connector.
