USR-W610 | RS232/485 to Wi-Fi/Ethernet Converter

USR-W610 is a device that can realize data communication between serial port and Ethernet/Wi-Fi. Through this device, the communication between the on-site serial device and the remote SCADA system can be realized. It has a 232 serial port and a 485 serial port, but the two serial ports cannot be used simultaneously. It integrates a wealth of network protocols like MQTT, TCP, UDP etc. and supports a variety of networking methods, suitable for various scenarios.

Ordering Guide

For serial to Wi-Fi/Ethernet convertor, PUSR offers 3 models to meet the needs of customers in different scenarios, and the main differences are shown in the table on the left.

 Multiple Networking Options

    ● The USR-W610 provides a wealth of networking methods to meet customer networking needs.
  • ● AP mode: Allow network devices to access USR-W610 via Wi-Fi or Ethernet.

  • ● STA mode: USR-W610 as a network device accesses other networks via Wi-Fi.

  • ● AP+STA mode: Work in AP and STA mode simultaneously.

  • ● Bridge mode: The device connected to the Ethernet port of W610 is equivalent to directly connecting to the upper-level network, and the W610 is equivalent to being transparent.

  • ● Router mode: The device connected to the Ethernet port of W610 will be assigned an IP by the W610.

Transparent Transmission Mode

Data is transmitted transparently between serial port and Wi-Fi / Ethernet via TCP/UDP/HTTP Protocol, enabling data transfer between serial port device and network device.

Transparent Transmission Mode

Data is transmitted transparently between serial port andWi-Fi/Ethernet via MQTT/TCP/UDP/HTTP Protocol, enabling data transfer between serial port device and remote SCADA system.

Serial Command Mode

In this mode, USR-W610 needs work as UDP Client or TCP Client, it allows users to send serial data to different servers. Data, server IP and port information should be included in the data packet sent by the serial device

 Addtional Features

  • • Modbus Gateway: Modbus RTU/TCP protocol conversion and multi-host Modbus polling.

  • • Heartbeat Packet Function: Remote server can detect abnormal disconnection from the client using this feature.

  • • Registration Packet Funciton: The server can identify different clients by usingregistration packets.

  • • Websocket Function: It can realize the real-time interaction between the serial device connected to W610 and the web page on PC.

   Industrial-Grade Design, High Reliability

  • • EFT Protection: Protect device against damage caused by instantaneous current interference in circuit, such as lightning stroke, power switch, etc.

  • • ESD Protection: Prevent electrostatic damage equipment, such as dust electrostatic, electric arc environment etc.
