The CB-114 Series offers flexible, high-performance 4-port RS-232/422/485 PC/104-Plus modules, ideal for multi-protocol serial communication in industrial embedded systems. Operating on the PC/104-Plus (PCI) bus, each module provides DIP switch-selectable interface modes per port to suit diverse serial requirements.

With up to 921.6 kbps baudrate, 128-byte FIFOs, and built-in hardware and software flow control, the modules are optimized for reliability and throughput. Tx/Rx LED indicators provide real-time monitoring of port activity. IRQ and I/O addresses are automatically assigned by BIOS, eliminating the need for jumper configuration. A wide-temperature model (-40 to 85°C) is available for rugged applications.
