This guide provides specifications for Unitronics’ Uni-COM™ CX Modules. Use them to add communication ports to specific models of the UniStream ® family of Programmable Logic Controllers. Compatible models comprise a Uni-COM™ CX Module Jack which provides the connection point for the module. Refer to the specifications of your UniStream model to check whether it is compatible with CX modules. UAC-CX-01RS2 offers one RS232 port, UAC-CX-01RS4 offers one RS485 port, and UAC-CX-01CAN offers one CANbus port. Installation Guides are available in the Unitronics Technical Library at www.unitronicsplc.com .
