CIM Connection Diagrams

Observe the diagrams on the following pages for connecting the CIM units to the access control boards and
connecting the CIMs with CAN Bus 1 and CAN Bus 2.
The CIM designated as CIM 0 supports serial or network (TCP/IP) to CANBUS 1 communication. The CIM unit
does not support modem communication.
Note
The control board's H2 terminal is an open terminal block and does not require setting S2 – switches 7 & 8 for
activation.
