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.

Quick Start

The simplest way to configure and use these modules is:

  • Connect the antenna, and power the module
  • On a PC with WiFi, look for a new network with "610" in its name, and connect to it
  • When asked for a username and password, use "admin" and "admin"
  • In a browser, connect to the built in webpage of the device at
  • Configure the device via the the "quick start" section of the webpage.
    • If two devices will be used to connect to each other, configure the one for AP(Access Point) mode, and the other for STA(Station). Remember the SSID of the device configured as AP, and use it for the device configured as STA. This way, the STA device will connect to the Access Point provided by the STA device.
