The CA-108 module from the CA-108 Series is a PC/104 bus 8-port RS-232 module designed for embedded systems and industrial environments requiring multiple serial interfaces. Built with four 16C550C-compatible UARTs, each port features a 64-byte FIFO to ensure stable and efficient communication even under high-throughput conditions.

DIP switches allow flexible configuration of I/O base addresses and interrupt vectors. Each port is equipped with built-in Tx/Rx LEDs for real-time monitoring. Extensive driver support for Windows, Linux, and UNIX platforms ensures versatile integration in various system architectures.
