    Product details of USR-K7

    Working mode

    Multiple Working Modes are Optional

    Supports five working modes of TCP Client, TCP Server, UDP Client, UDP Server and Httpd Client.
    The data transmission can be realized with simple configuration.


    UDP Client is a connectionless transport protocol in which
    K7 can only communicate with the target port of
    the target IP.

    In UDP Server mode, the data received by serial port
    is automatically sent to the network target of the
    last communication.

    USR-K7 supports working modes of UDP Client, UDP Server.HTTP Client mode of usr-k7

    Data Submitted Directly to Web Server

    Supports the data interaction between the terminal device and the web server directly. Without considering the conversion process,
    the data request from the serial port to the HTTP server can be realized quickly by simply setting parameters.

    USR-K7 Supports Httpd Client Mode


    Virtual COM

    Solves the problem that PC software as serial port can not
    communicate with networked devices

    Disconnection identification, automatic connection

    Easy identification of dead links and auto re-connection to
    prevent data loss due to power outages and disconnections


    Modbus Gateway

    Polling mechanism can effectively solve the problem
    of congestion caused by data concurrency
    (firmware 3009 or higher)

    Custom built-in web page, Function of Web to Serial

    Design built-in web pages according to project requirements,
    realize web page control, web page data acquisition.

    USR-K7 supports Virtual COM
    USR-K7 supports modbus gateway, custom build-in web page, web to serial


    Networked Monitoring of Medical Machinery

    K7 can realize the data transmission between serial port and network quickly thus reducing the manpower on duty.
    At the same time,multiple medical devices can be combined into local network to realize real-time information.

    application of USR-K7: Networked Monitoring of Medical Machinery

    Industrial Automation Network Monitoring

    Many traditional serial port devices does not have networking capability.  K7 module integrated TCP/IP protocol stack
    can provide the solution of network communication between serial device to server via network
    based on socket to improve the level of industrial automation.


    application of USR-K7: Industrial Automation Network Monitoring

    Networked Monitoring of Medical Devices

    The power data of the distribution box needs to be collected and reported in real time.
    Tiny size module K7 is industrial-grade design which can provide reliable and stable networking
    functions and suitable for the integrated project requirements of power monitoring
