  • This is a RS485 device data acquisitor / IoT gateway designed for industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to HTTPD Client, etc.
  • With RS485, W-i-F--i and Ethernet ports, the module can realize functions such as serial to W-i-F--i, serial to Ethernet, Ethernet to W-i-F--i and so on. Using screw terminals for power input, it supports 5~36V wide range power supply.
  • Support Transparent Transmission Mode: Supports TCP Server / TCP Client / UDP Server / UDP Client. Serial Command Mode: The user sends data to the server according to the protocol. Send data to different servers without restarting.
  • Support HTTPD Client Mode: After the user has set the HTTP header through AT commands or web page, the module can send data to the HTTP server, or obtain data from the HTTP server.
  • Modbus Gateway support: Support Modbus TCP and Modbus RTU interconversion mode.
  • AT command mode: The user can query the current status of the module, or set related parameters, by sending AT commands.
  • Support MQTT function: Devices can subscribe to other MQTT client messages, and can publish topic information to the server. Supports subscription of 6 messages and publication of 6 topics, wider range of use and more applicable scenarios. Users can view device-related information through terminal devices or cloud platforms.

FAQ
Question: Why can't the configuration web page be opened in the computer's browser and cannot communicate with TCP?
Answer:Set the IP of RS485 TO W-i-F--i/ETH and computer to the same network address and different node address IP:
For example, RS485 TO W-i-F--i/ETH IP is 10.10.100.254; computer IP is 10.10.100.253
