  • USR-K3 Serial to Ethernet Converter (Super Port)

    The USR-K3 product is an small package, intelligent plug-and-play UART to Ethernet adapter. K3 enables any device or machine with a serial port(UART), to become Ethernet network and Internet enabled, and have network data transmit ability. It features a powerful built-in device server, so you can access your serial device from anywhere in the world over internet! The USR-K3 is easily configured via local network, or through the serial port and web pages.

    USR-K3 is an embedded TCP/IP modules that integrates the TI Cortex-M4 processor which can provide improved performance and high stability. This module has a high frequency of up to 120 Mbps. It is also a highly integrated module that includes TTL,Ethernet port, built-in network transformer, all these can easily achieve data transmission between TTL and Ethernet port and greatly reduce user’s development time and improve their development progress.
