8-Channel Serial Server RS485 RS232 RS422 to RJ45 ModBus Gateway RTU to TCP NB183S Build-in Watchdog MQTT/HTTP IOT Module - CDBAIRUI, 0302050300000003

• Basic Function-Two-way data transparent transmission between serial port and Ethernet RS485/232 Ethernet.Serial port works independently ,Independent setting parameters.Reconnect After Disconnection Automatically initiate a connection to the server after the network is stuck and disconnected 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. ModBus TCP- RTU,Support standard ModBus TCP to RTU protocol automatic conversion.Storage Gateway,The device automatically memorizes the Ethernet query command and automatically polls on the serial line.Virtual Serial Port To solve the problem that PC software as a serial port cannot communicate with networked devices 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.Heartbeat Packet Serial heartbeat packets and network heartbeat packets keep the link running stably 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.Industrial Standard The module can work in the harsh environment of -40°C~+85°C.
