The CA-134I Series is a line of 4-port RS-422/485 PC/104 modules featuring 2 kV optical isolation on all ports, ideal for mission-critical industrial communication. With baud rates up to 921.6 kbps, on-chip software flow control, and per-port Tx/Rx status LEDs, these modules are built for performance, stability, and ease of integration into embedded systems.

Fully compatible with the PC/104 bus architecture, the modules support a wide range of operating systems including Windows CE 5.0/6.0, Windows XP Embedded, and more. Optional DB9 and DB25 cable kits are available for easy device connections. A wide-temperature model (-40 to 85°C) is available for harsh environments.
