Ethernet interface 232 485: 2KV





Work Mode

  • Transparent Transmission Mode

In this mode, all transmitted/received data is not parsed between the serial port and the WiFi interface.  It minimizes the complexity of user usage.

  • HTTP Client Mode

In this mode, serial data will be submitted to the HTTP server via HTTP GET/POST/PUT requesting method.

  • AT Command Mode

In this mode, user can query/set parameters via serial AT commands or network AT commands.

Special Features

  • Modbus Polling Mode

In this mode, it supports Modbus TCP and Modbus RTU mutual conversion.

  • Heartbeat Packet Function

USR-W610 supports network heartbeat packet and serial heartbeat packet. The network heartbeat packet notifies the server that it is in an active state, and it maintains the normal connection with the server by continuously sending the heartbeat packet.Serial port heartbeat packet notifies the serial device that USR-W610 is in an active state, and takes the initiative to grab the sensor data can not be initiative to push.

  • Socket Distribution Protocol

USR-W610 suppports SDP, you can add certain header in serial data. It will send the data to differetnt socket by different header. The data received from different
socket will be added different header before they are sent to serial.

  • Regular Restart Function


1. Intelligent Power Data Acquisition Solutions

  • Build-in routing function, supports wired or WiFi networking method.
  • Remotely monitoring meter data, it not only saves manpower and resources but also facilitates the sudden response measures.
  • Rapid collection of data in the monitoring and management platform, it facilitates the city electricity management then to achieve smart city.

2. Smart Agriculture

  • Monitoring the situation in the greenhouse,such as utilization rate about water resources, fertilizers and so on.
  • To obtain farmland information and monitor sudden natural disasters, then to carry out standardized control measures.
  • Fully automated operation without human intervention, saving manpower and achieving the precise control of agriculture.


3. Industrial Detection
