The CAN bus is connected to the AP71 connection board by a 9-pin Sub-D
connector. You can connect two independent CAN field bus systems (female
connectors CAN1 and CAN2). Both the CAN interfaces are used to output the
MGCplus measurement data. Each of the interfaces can be assigned up to
128 measured values.
