Special Features

  • 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, WIFI and Ethernet ports, the module can realize functions such as serial to WIFI, serial to Ethernet, Ethernet to WIFI 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 WIFI/ETH and computer to the same network address and different node address IP:
For example, RS485 TO WIFI/ETH IP is 10.10.100.254; computer IP is 10.10.100.253
