General Details

Introduction of  Lan Port TTL Ethernet Module

USR-K3 is the high-performance and industrial version of Super LAN Port TTL Ethernet Module. The amazing part of K3 lies in its Ethernet port integration design. K3 is based on Cortex-M4 solution, which has high speed,high stability and basic frequency up to 120MHz.

Features of TCP Modules

  • Cortex-M4 kernel,industrial working temperature range and TCPIP protocol stack.
  • Auto-MDI/MDIX,RJ45 port with 10/100Mbps

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.
