    Function Structure of 2 serial ports serial to Ethernet converter USR-N520

    Work mode

    TCP Server

    Serial server device N520 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 2 serial ports serial to Ethernet converter USR-N520:TCP Server

    TCP client mode

    The serial converter N520 initiates a TCP lint to the set IP address.
    If the connection fails, N520 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 2 serial ports serial to Ethernet converter USR-N520:TCP Client

    UDP mode

    Serial device server will transmit serial data from serial device to
    target network device by UDP connection.
    Serial device server will listen to port and transmit all received data to serial device.

    work mode of 2 serial ports serial to Ethernet converter USR-N520: HTTPD Client

    HTTPD Client

    Supports HTTP Client mode which can transmit serial data to the HTTP server in HTTP format(GET/POST).

    2 serial ports serial to Ethernet converter USR-N520: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

    2 serial ports serial to Ethernet converter USR-N520 Supports WebSocket Sever
