2-Channel Serial Server Edge Computing Gateway RS232 RS422 RS485 RJ45 Modbus Gateway NB124ES POE Receiving Power TCP/UDP/MQTT DC 8-28V

Basic Function,Two-way data transparent transmission between serial port and Ethernet RS485/232/422 < Ethernet,Serial port works independently ,Independent setting parameters;ModBus TCP = RTU,Support standard ModBus TCP to RTU protocol automatic conversion.Industrial Standard The module can work in the harsh environment of -40°C~+85°C;
Provide Four Communication Mechanisms Of TCP And UDP ,Fast configuration to achieve transparent data transmission; TCP » Sever Function,Support 6-way Socket connection;TCP » Client Function;UDP » Sever Function,Support 6-way Socket connection;UDP » Client Function.;Built-in Watchdog Built-in software/hardware watchdog ensures the stability of the device
Storage Gateway ,The device automatically memorizes the Ethernet query command and automatically polls on the serial line;Configurable Gateway The serial port polling command is preconfigured, the device automatically polls the serial port data when it is powered on, and the server can execute the response immediately after the request.
Adapt To A Variety Of loT Transmission Protocols TCP / UDP / MQTT / HTTP;Multiple Configuration Methods Host computer / AT command;Registration Packet,Support 4 data types of registration packet to verify link security and stability;
Heartbeat Packet ;Serial heartbeat packets and network heartbeat packets keep the link running stably;Reconnect After Disconnection,Automatically initiate a connection to the server after the network is stuck and disconnected;Virtual Serial Port To solve the problem that PC software as a serial port cannot communicate with networked devices.
