USR-W630 | RS232/485 to Wi-Fi/Ethernet Converter

USR-W630 is a device that can realize data communication between RS485/RS232 and EthernetWi-Fi Through this device the communication between the on-site serial device and the remote SCADA system can be realized. It integrates a wealth of network protocols like MQTT, TCP. UDP etc and supports a variety of networking methods, suitable for various scenarios.

Multiple Networking Options

The USR-W630 provides a wealth of networking methods to meet customer networking needs.

• AP mode: Allow network devices to access USR-W630 via Wi-Fi or Ethernet.

• STA mode: USR-W630 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 W630 is equivalent to directly connecting to the upper-level network, and the W630 is equivalent to being transparent.

• Router mode: The device connected to the Ethernet port of W630 will be assigned an IP by the W630.

Data Transmission Encryption

  • Supports SSLTLS encryption in TCP cient, HTTP client and MQTT operation modes.

  • Supports two-way certificates authentication.

Transparent Transmission Mode

Data is transmitted transparently between RS485 and Wi-Fi / Ethernet via TCP/UDP/HTTP Protocol, enabling data transfer between serial port device and network device.

Serial Command Mode

In this mode, USR-W630 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 W630 and the web page on PC.

PUSR: Cloud SCDA Solution

PUSR provides a cloud-based SCADA system that allows users to upload data from field devices to the SCADA system for remote monitoring and data management to realize the potential of the equipment.
