General Details

Introduction of RS232 / RS485 Serial Wireless Servers

USR-WIFI232-630 wifi serial server is a wireless networking server, which is used for project of RS232/RS485 serial equipment to WIFI or Ethernet networking. and It has 2 channel RJ45 port.

Feature of RS232 / RS485 Serial Wireless Servers

  • Httpd Client: serial data submitted to server by HTTP (GET/POST)
  • Websocket: support bidirectional transparent transmission between built-in webpage and serial
  • DNS/DHCP: support dynamically to acquire domain and IP
  • Username/Password Verification
  • Modbus: support mutual conversion between Modbus TCP and Modbus RTU
  • TCPB Function: support 2 network links and send data to 2 targets
  • Customized MAC: users can define the MAC address by themselves
  • Built-in Webpage
  • Firmware Upgrade through Webpage
  • ID Registration: send ID package when TCP establishes connection,or each data automatically increases ID packet header
  • Virtual Serial Software (USR-VCOM) automatically connect devices
  • Baud Rate Sync: network protocol dynamically sets serial parameter
  • 485 Protection: overcurrent protection, lightning protection, anti-static
  • Power Protection: reverse connection protection, anti-static, anti-surge
  • ESD Protection: pass the test of 8KV contact discharge

5.Daisy-chained Connection – Double Ethernet Application

Daisy-chained Connection

Simple Transparent transmission

Transparent transmission means that whatever is transferred, our device plays the role of a channel and sends data to the target without modification. On-site monitoring equipment sends data to Wireless Device Servers transparent data transmission terminal by itself port, the terminal CUP receives data by serial port and package data.

Various parameter setting method

Software Settings
Download settings software, search Wireless Device Servers in the LAN through the serial port server IP, name, MAC address, or the version number. Then set the parameters you need, otherwise keep the default.
Web-page Settings

  1. Open your browser and inter the default IP address of the Wireless Device Servers.
  2. Open the login page of Serial Server, Enter the user name and password (default admin).
  3. After setting parameter, Click “Save“ and “Restart“, then setting will take effect.

Serial AT commands Settings
User can set parameter by module itself without going through another computer to configure. This setting method is used in the following situation: user have to configure IP address and destination IP address on site. AT command can meet the demand. After MCU connects serial server module by TTL (UART), MCU can configure setting by AT command.
