    Working mode

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

    Serial to Ethernet converter 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.

     

    tcp server, DIN-rail RS485 serial to Ethernet converter

     

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

     

    UDP Client, 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.

     

    UDP Server, 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).

     

    HTTPD Client, DIN-rail RS485 serial to Ethernet converter

    Support Modbus gateway

     

    DIN-rail RS485 serial to Ethernet converter supports modbus gateway

    More functions

    Virtual serial software

    Solve the problem of PC software
    as a serial port can not communicate
    with networking device.

    Network Heartbeat Packet

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

    Identity Heartbeat Packet

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

    Advanced protection

    Level 4 anti-static,
    level 3 electrical pulse protection,
    level 2 surge protection

    DIN-rail RS485 serial to Ethernet converter: Identity Heartbeat Packet

    DIN-rail RS485 serial to Ethernet converter can identity Heartbeat Packet

    Application

    Power data networking transmission

    Small size which is available for narrow space;
    DIN-rail mounting, easy to install on the wall;
    The terminal data of the distribution box can quickly convert into the network data,
    real-time communication, reduce the cost effectively.
