How To Connect


Software Preparation

Start Communication

  • Open Vircom->Device Management-> Double-click the corresponding device ->Firmware Config->MQTT Config.


  • Alibaba cloud platform -> Device -> Device Information.


  • Configure the MQTT parameters of the Alibaba Cloud IoT platform to one of the RS485 TO ETH (B).


  • Download MQTT parameters to RS485 TO ETH(B).


  • Check the parameter of MQTT text in the corresponding file.


  • Config MQTT parameter -> The Link light of RS485 TO ETH changes from yellow to blue -> successfully connected to the MQTT server


  • IoT platform device display offline -> online.


  • RS485 TO ETH(B) sends data to Alibaba Cloud MQTT server.


  • Alibaba Cloud IoT platform sends information to RS485 TO ETH(B).


  • RS485 TO ETH (B) Connect Alibaba Cloud and EMQX (optional).

Open Vircom->Device Management->Double-click the corresponding device->Firmware Config->MQTT Config.

  • Configure EMQX's MQTT parameters to another RS485 TO ETH(B)


  • Alibaba Cloud sends data to EMQX: Hello, EMQX!


  • EMQX sends data to Alibaba Cloud: Hi, ALY!
