Serial Ethernet Module Introduction

This is a serial TTL to Ethernet module, used for data transparent transmission. USR-K7 is the high-performance and industrial version of Super Port. It is an embedded serial networking module, whose function is to realize bidirectional transparent transmission between TTL and Ethernet. You can apply USR-K7 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.

USR-K7 ( The updated version of old module USR-K3) is based on Cortex-M4 solution, which has high speed,high stability and basic frequency up to 120MHz. 

Serial Ethernet Module Features

  • TI cortex-M4 solution, ARM kernel and TCP/IP protocol stack
  • DNS, DHCP, Websocket and HTTPD Client supported
  • Keepalive function,rapidly detect dead links
  • Built-in webpage, support customized
  • Can upgrade firmware via network easily
  • Account and password to page login and network settings
  • Support UDP broadcast,send and receive data from all IP in LAN
  • Global unique MAC address bought from IEEE, can be defined
  • Virtual serial port, setup and test software is availiable
  • Provide PC TCP/IP SOCKET programming example: VB, C++, Delphi, Android, IOS
