Repeat connections and jumper settings for each control board and CIM.
Apply power to all CIM and ACU circuit boards.
Do one of the following procedures at the control board:
If this is an existing system, press reset S1 on the control board for board initialization.
If this is a new installation, press S1, wait 5 seconds, and then press S3 within ten seconds. Allow two
minutes for board initialization after clearing memory.
Return to a PC with the Client module, log on to the appropriate site, and perform a full upload.
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.
