    tcp client of working mode of DIN-rail RS485 serial to Ethernet converter

    Working mode

    Serial to Ethernet converter USR-DR302 will initiate TCP connection to the destination IP address
    that configured by the user and serial to Ethernet converter will continuously try to reconnect
    if establishing TCP connection unsuccessfully.

    tcp server, DIN-rail RS485 serial to Ethernet converter

    Serial to Ethernet converter USR-DR302 monitors the set port and waits
    for a TCP client connection. Data from the serial device will transmit
    to all successfully-connected via serial to Ethernet converter.

    UDP Client, DIN-rail RS485 serial to Ethernet converter

    USR-DR302 only communicates with the target interface of the target IP,
    thus to assure the accuracy of data transmission.

    UDP Server, DIN-rail RS485 serial to Ethernet converter

    DR302 can transmit the data automatically to the last time transferred
    device after receiving the data, which is suitable for multi-network
    devices that need to communicate with the DR302.

    HTTPD Client, DIN-rail RS485 serial to Ethernet converter

    DR302 supports the function of transmitting the serial data to the
    specified server in the form of HTTPD (GET/POST).

    DIN-rail RS485 serial to Ethernet converter supports modbus gateway
