  • USR-K2 Serial to Ethernet Converter (Super Port)

    The USR-K2 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-K2 adopts Cortex-M0 processor with a main frequency of up to 48MHz. It has the exact same appearance as K3. Users can switch between the two models without any change in hardware.
