    Function Structure of USR-N540, 4 serial port Ethernet converter

    Work mode

    TCP ServerSerial server device USR-N540 listens on the setting port
    and waits for a TCP client connection.
    The data which the serial ports sent out transparently
    transmit to all connected client via serial device N540.

    Work mode of USR-N540, 4 serial port Ethernet converter: TCP Server

    TCP client mode

    The serial converter USR-N540 initiates a TCP lint to the set IP address.
    If the connection fails, USR-N540 will keep trying to reconnect until it succeeds.
    Once the link is successful, the data will be transparently
    transmitted between PC and serial device in bi-directional.

    Work mode of USR-N540, 4 serial port Ethernet converter: TCP client mode

    UDP mode

    Serial server device N540 sent the data to designated IP /Port.
    If the connection fails, N540 will keep trying to reconnect until it succeeds.
    Meanwhile, N540 listens the port and forwards
    all data received to serial device.

    Work mode of USR-N540, 4 serial port Ethernet converter: UDP mode

    HTTPD Client

    Support serial data transmitted to designed server in HTTPD way

    Work mode of USR-N540, 4 serial port Ethernet converter: HTTPD Client

    WebSocket

    Supports WebSocket Sever,
    Built Websocket link with devices by Websocket of webpage HTML5
    Data transmission between built-in webpage and serial port in bi-directional
    Custom webpage and websocket are acceptable
    Achieves the functions of displaying data in real-time

    Work mode of USR-N540, 4 serial port Ethernet converter : WebSocket

    USR-N540, 4 serial port Ethernet converter: Virtual Com Software

    Special function

    Synchronized baud rate

    Change the baud rate, data bit, check bit
    and stop bit dynamically via network commitment

    USR-N540, 4 serial port Ethernet converter : Special function

    Serial Port/ Network heartbeat package

    Network heartbeat package: The serial server device N540 notifies the server
    that it is active by sending Heartbeat Package regularly,
    and maintains normal network links with the server.
    Serial Port heartbeat package: The server notifies the serial device
    that it is active, and the user can also actively grab the sensor data.
