General Details

Introduction of Embedded Super Ports

This is a serial TTL to Ethernet module, used for data transparent transmission. USR-K2 is the low-cost and multifunctional version of Super Port. It is an embedded serial networking module, whose function is to realize bidirectional transparent transmission between TTL and Ethernet.
The amazing part of K2 lies in its Ethernet port integration design. You can apply K2 to your products to realize networking communication. User can directly process data interaction through network and device to realize remote data acquisition, remote control and management.
K2 is based on M0 solution,which has slightly higher price and a bit more functions than K1.

Various parameter setting method

Software Settings
Download settings software, search Ethernet Modules 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 Ethernet Modules.
  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.
