The DS-MPE-SER4M is a rugged, low cost 4-port high speed PCIe MiniCard module that is ideal for serial I/O expansion in embedded and OEM applications.

It offers four RS-232/422/485 serial ports in the PCIe MiniCard full size form factor with an extended operating temperature of -40C to +85C. Data rates on every port are up to 1Mbps in RS-232 mode, and 10Mbps in RS-422 and RS-485 modes. The board’s protocols can be set by jumpers or programmatically selected with GPIO lines built into the UART and controlled via software. The serial I/O signals are provided on two miniature connectors with two ports per connector.

Extended temperature capability (-40C to +85C) 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.

The DS-MPE-SER4M product comes with the PCIe MiniCard hardware assembly, a cable kit with two dual serial cables, and a hardware kit containing jumpers and mounting screws.
