The CA-114-T is a rugged and versatile 4-port RS-232/422/485 serial module for PC/104 systems, designed for -40 to 85°C wide temperature environments. Each port is user-configurable via DIP switches for RS-232, RS-422, or RS-485 operation, offering flexible integration into a wide range of industrial and embedded applications.

Equipped with four 16C550C-compatible UARTs, each with 64-byte FIFOs, the module supports high-speed communication up to 921.6 kbps. DIP switches allow configuration of I/O base address, interrupt vector, and serial interface mode. Built-in Tx/Rx LEDs provide instant port activity feedback. The CA-114-T supports a wide range of Windows and Linux drivers for easy deployment.
