        between RS485 and Wi-Fi / Ethernet

        Function Structure introduction of WIFI serial device server USR-DR404,

        Function Structure


        Work Mode

        Transparent Transmission Mode

        Data is transmitted transparently between serial port and
        Wi-Fi / Ethernet via DR404, enabling data transfer
        between serial port device and network device

        WIFI serial device server USR-DR404

        Serial Command Mode

        The user sends data to the server according to the protocol
        and can send data to different servers without restarting.

        AT Command Mode

        Users can query the current status of DR404
        or set relevant parameters by sending AT instructions

        Features of WIFI serial device server USR-DR404


        Modbus Gateways

        Mode of transferring data
        between Modbus TCP and Modbus RTU.

        Socket Distribution

        In transparent transmission mode, the serial device
        can send data to the specified Socket connection.
        Network data for each Socket are sent to
        the serial device via the serial port.

        Quick Networking Protocol

        Mobile phone connect to the AP of DR404, you can directly
        set the specified AP to which DR404 connects by querying
        surrounding AP’s SSID list through USR-LINK, which is
        convenient and fast. You can quickly connect to the Internet
        without operating DR404.

        Custom Registration Package,
        Heartbeat Package

        The registry package is used for easy device
        identification from the server.
