The CA-132I-T is a rugged 2-port RS-422/485 PC/104 serial module featuring 2 kV optical isolation to protect against signal surges and electrical interference. Designed for harsh industrial environments, it supports a wide operating temperature range of -40 to 85°C and is ideal for embedded systems requiring secure and reliable serial communication.

The module integrates two 16C550C-compatible UARTs with 64-byte FIFOs, and supports flexible configuration via DIP switches for I/O address and IRQ selection. Each port includes Tx/Rx LEDs for real-time status monitoring. It comes with comprehensive driver support for Windows, Linux, and UNIX, ensuring ease of integration into a variety of platforms.
