The CA-132/132I Series offers reliable, high-performance 2-port RS-422/485 PC/104 modules built for industrial embedded communication applications. These modules support baud rates up to 921.6 kbps and integrate key features like on-chip software flow control, ADDC® for RS-485, and LED indicators for Tx/Rx activity.

Models CA-132I and CA-132I-T provide 2 kV optical isolation for environments with potential electrical noise, while the CA-132I-T also supports wide temperature ranges (-40 to 85°C). Compatibility with Windows CE 5.0/6.0, Windows XP Embedded, and many other platforms makes these modules highly versatile. Optional DB9 and DB25 cables are available for connecting to external serial devices.
