Technical parameters

Product Description

Industrial serial to WiFi and Ethernet converter

1 Port WiFi to serial converter ST-W631, which can realize bidirectional transparent transmission between RS232/RS485 and WIFI, WiFi and Ethernet, Serial and Ethernet.

 Hardware Interface

Features

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

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

3.         Electrostatic protection

4.         Hardware WatchDog, 24 hours stable operation.

5.         Timeout reset function, timing reset function.

6.         Supports identity packet function.

7.         Supports heartbeat packet function.

8.         Websocket function

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

10.     Hardware reload.

11.     WIFI Standard: 2.4GHz 802.11b/g/n

12.     Work Mode:TCP Server/TCP Client/UDP Server/UDP Client/https Client mode.

13.     Supports AP, STA, AP+STA.

14.     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

ST-W631 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 ST-W631 is in an active state, and takes the initiative to grab the sensor data can not be initiative to push.

3. Socket Distribution Protocol

ST-W631 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.

Applications
