    Working mode of Din rail RS232 serial to Ethernet converter USR-DR301

    Working mode

    Serial to Ethernet converter USR-DR301 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.

    Working mode of USR-DR301: TCP client

    Serial to Ethernet converter USR-DR301 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.

    Working mode of USR-DR301: TCP Server

    USR-DR301 only communicates with the target interface of the target IP,
    thus to assure the accuracy of data transmission.

    Working mode of USR-DR301: UDP Server

    DR301 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 DR301.

    Working mode of USR-DR301: HTTPD Client

    DR301 supports the function of transmitting the serial data to the
    specified server in the form of HTTPD (GET/POST).

    Din rail RS232 serial to Ethernet converter USR-DR301 supports Modbus gateway function

    Support Modbus gateway
