Connecting the ICIM to Additional Chassis
Chassis-to-Chassis ICIM Connections
The Prisma II platform allows the ICIM to be located in one chassis and control
modules located in several other chassis. This communication “daisy-chain” can be
enabled by connecting cables to the ICIM IN and ICIM OUT connectors located on
the connector interface panel of the chassis. This connection is required if an ICIM in
one chassis is to communicate with or control any module located in a separate
chassis.
Note: An ICIM can control a maximum of 140 modules. Depending on your
Note: An ICIM can control a maximum of 140 modules. Depending on your
application, this is typically 6 or 7 chassis to a rack. Do not exceed these limits.
ICIM IN and ICIM OUT Connectors
Every Prisma II Standard and II XD Chassis has a DB9 ICIM IN and a DB9 ICIM
OUT connector for the purpose of chassis-to-chassis ICIM connections. ICIM IN is a
female connector and ICIM OUT is a male connector.

ICIM IN and ICIM OUT Cables
The cable required for both ICIM IN and ICIM OUT connections is a shielded 9-
wire serial extension cable, DB9 Female to DB9 Male. This cable can be purchased
locally or from the factory. The chassis data sheet lists the part number for a 6-foot
DB9 Female to DB9 Male serial extension cable. The connectors are a serial 9-pin D-
shell (EIA 574/232).
