Zusammenfassung:The utility model provides a serial port networking communication device. The serial port networking communication device is characterized by comprising a multi-path RS232/RS485/RS422 three-in-one serial port transceiver, the Ethernet and a CPU, the multi-path RS232/RS485/RS422 three-in-one serial port transceiver is connected with the CPU, the CPU is connected with the Ethernet, the CPU packages data received by the multi-path RS232/RS485/RS422 three-in-one serial port transceiver in the uplink direction, a data packet sent through the Ethernet, the CPU receives the data packet of the Ethernet in the downlink direction and transparently sends original data in the data packet to a serial device through a corresponding serial port in the multi-path RS232/RS485/RS422 three-in-one serial port transceiver, and independent data transmission rates are adopted in the uplink direction and the downlink direction. The serial port networking communication device supports three serial interfaces including RS232, RS485 an
