The Prisma II platform allows the ICIM2 or ICIM2-XD 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 ICIM2 or ICIM2-XD in one chassis is to communicate with or control 
any module located in a separate chassis. 

Note: An ICIM2 or ICIM2-XD 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. 

 

Every Prisma II standard and Prisma 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.

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).
