The CA-134I Series consists of 4-port RS-422/485 PC/104 modules with 2 kV optical isolation, engineered for high-reliability serial communication in industrial environments. With a maximum baudrate of 921.6 kbps, on-chip software flow control, and Tx/Rx status LEDs on every port, these modules ensure high-performance data transmission and simplified diagnostics.

The modules are fully compatible with the PC/104 expansion interface and support popular embedded operating systems including Windows CE 5.0/6.0 and Windows XP Embedded. A wide-temperature model (-40 to 85°C) is available for outdoor or rugged deployment. Optional DB9 and DB25 cable kits facilitate easy device connections.
