The DS-MPE-SER4OPT is a rugged, low cost 4-port opto-isolated PCIe MiniCard serial module that is ideal for serial I/O expansion in embedded and OEM applications.

It offers four RS-232/485 serial ports in the PCIe MiniCard full size form factor with an extended operating temperature of -40ºC to +85ºC. Data rates on every port are up to 1Mbps in RS-232 mode, and 10Mbps in RS-485 mode. Models can be ordered with 4 RS-232 ports, 4 RS-485 ports, or 2 RS-232 and 2 RS-485 ports.

Extended temperature capability (-40°C to +85°C) enables the board to operate in environments with extreme temperature swings, such as vehicles or outdoor installations. In addition, the board may be custom-configured with 0-ohm resistors in place of jumper blocks for increased ruggedness in high-vibration environments.
