The CB-114 Series offers reliable and flexible 4-port RS-232/422/485 PC/104-Plus modules, designed for embedded and industrial systems requiring high-speed, multi-protocol serial communication. The interface type (RS-232, RS-422, RS-485) is DIP-switch selectable per port, providing configuration flexibility.

With a maximum baudrate of 921.6 kbps, 128-byte FIFOs, and on-chip hardware and software flow control (RTS/CTS, XON/XOFF), the CB-114 ensures stable and efficient data transmission. Each port includes Tx and Rx LED indicators for live diagnostics. The module’s IRQ and I/O addresses are assigned by BIOS, eliminating the need for jumpers. A wide-temperature version (-40 to 85°C) is available for demanding environments.
