[Introduction]:NE2-H14 serial port server is used to realize bidirectional transparent transmission of data from RS485/RS232/RS422 serial port to Ethernet port. It has multiple Modbus gateway modes and MQTTC/HTTPC IoT gateway modes, which can meet the networking functions of various serial port devices/PLCs; it adopts industrial-grade design standards to ensure equipment reliability. The serial port server realizes transparent transmission of serial port data to Ethernet TCP/IP data packets. Users do not need to care about the specific details, and the protocol conversion is completed inside the device.
