General Details

Product Description

Industrial Serial To WiFi and Ethernet Converter
2 Ethernet ports Serial To WiFi and Ethernet Converter USR-W630, which can realize bidirectional transparent transmission between RS232/RS485 and WIFI, WiFi and Ethernet, Serial and Ethernet. 



Two Ethernet ports: 1x LAN, 1x LAN/WAN. Two Ethernet ports (WAN and LAN) can be worked simultaneously

Modbus gateway: Modbus TCP to Modbus RTU in bi-directional; Modbus Polling

Electrostatic protection

Hardware WatchDog, 24 hours stable operation.

Timeout reset function, timing reset function.

Supports identity packet function.

Supports heartbeat packet function.

Websocket function

Supports Web Server, setup software, serial/network AT command to configure module.

Hardware reload.

WIFI Standard: 2.4GHz 802.11b/g/n

Work Mode:TCP Server/TCP Client/UDP Server/UDP Client/HTTP Client mode.

Supports AP, STA, AP+STA.

Supports usrlink.

EFT: Passed EFT test, when there is instantaneous high current in the circuit (such as lightning, power switch, etc.), it can ensure that the device hardware is not damaged. Power: 2KV, Ethernet interface 232 485: 2KV


Special Features

1.Modbus Polling Mode

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


2. Heartbeat Packet Function

USR-W630 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-W630 is in an active state, and takes the initiative to grab the sensor data can not be initiative to push.


3. Socket Distribution Protocol

USR-W630 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.


4. Regular Restart Function

USR-W610 supports timing and timeout restart function, which makes the system run more stable.
