[Introduction]：NE2-D12P single serial port server is an isolated serial port server used to realize bidirectional transparent transmission of data from RS232 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.
