    work mode of RS485 Serial to Ethernet Converters,tcp server mode

    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 of RS485 Serial to Ethernet Converters,tcp client mode

    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 of RS485 Serial to Ethernet Converters,UDP mode

    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 RS485 Serial to Ethernet Converters,HTTPD Client

    HTTPD Client

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

    Synchronous Baud Rate

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

    Identity packet function

    Identity packet function

    When 304 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 & Network Heartbeat Packet

    Serial & Network Heartbeat Packet

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