[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.The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. 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.
