The utility model discloses a multichannel serial card based on PXIe bus, change serial ports unit, FPGA unit, electrical unit and PXIe interface unit including connector unit, level switching unit, PCIe, the signal input state of FPGA unit passing signal line detection PXIe interface unit, then FPGA unit passing signal line traffic control the PCIE signal of FPGA unit inputs in the PCIe commentaries on classics serial ports unit, then PCIe changes the serial ports unit and converts PCIE signal to serial port signal, exports among the outside serial port equipment behind level switching unit and connector unit in proper order. The utility model discloses a FPGA unit control PCIe changes the serial ports of serial ports unit receiving and dispatching different grade type for communication between different serial portss and the PXIe interface is more convenient, can how compatible different grade type serial ports thereby reach, be convenient for control communicate with's between serial ports and the PXIe int
