    Function Diagram

    Work mode: TCP Server mode of Serial to Ethernet converter USR-TCP232-302

    Work mode

    TCP Server

    Serial device server monitors the set port and waits for a TCP client connection.
    Data from the serial device will transmit to all successfully-connected via serial device server.

    Work mode: TCP Client mode of of Serial to Ethernet converter USR-TCP232-302

    TCP client mode

    Serial device server will initiate TCP connection to the destination IP address that configured by the user
    and serial device server will continuously try to reconnect if establishing TCP connection unsuccessfully.
    If the serial device server establishes TCP connection to TCP Server successfully, it can realize
    bidirectional data transparent transmission between TCP Server and the serial device.

    Work mode: UDP Client of of Serial to Ethernet converter USR-TCP232-302

    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:  HTTPD Client mode of of Serial to Ethernet converter USR-TCP232-306

    HTTPD Client

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

    Virtual Com Software

    Serial to Ethernet converter USR-TCP232-306: Synchronous Baud Rate

    Synchronous Baud Rate

    Dynamically change baud rate, data bit, check bit and stop bit of serial device server via network command.

    Serial to Ethernet converter USR-TCP232-302: Identity packet function

    Identity packet function

    When 302 works as TCP Client, it can send identity packet to TCP server which can be identification.
    Identity packet can be IMEI code, ICCID code and user editable identity packet.

    Serial to Ethernet converter USR-TCP232-302: Synchronous Baud Rate

    Serial & Network Heartbeat Packet

    Serial server maintains the normal connection with the server by sending heartbeat packet regularly.

    Application Field of RS485 serial device server: Unattended Weighing

    Application

    [ Unattended Weighing ]

    Connect serial to ethernet converter USR-TCP232-306 to barrier gate and it can realize remote control of
    barrier gate by Ethernet in control center.

    Application Field of RS485 serial device server: access control system
    Application Field of RS485 serial device server: Traffic Lights Management System

    [ Traffic Lights Management System ]
