Site Controller CAN Bus

The CAN Bus provides a common communication bus between RFDS equipment, Power Supply Unit (PSU) and the
Site Controller. The CAN Bus connects to the Site Controller, PSU, DPM, and ATCC. The modules on the CAN Bus
are assigned an address for the CAN Bus. When there are more than one modules of the same type, assigned a

the unique track number is available from each unit.
At initialization of the MTS, the factory configures the Site Controller with a relation between track number and the
function of the node. You can modify this configuration in a service situation.
If a node is removed or is defective, the Site Controller knows the track number of a non-responding FRU and
therefore it can make a proper service report which tells exactly what FRU to replace. When the service is carried out,
