Working mode
TCP client
Serial to Ethernet Converter The USR-DR302 initiates a TCP connection to the user configured destination IP address, and the Serial to Ethernet Converter continually tries to reconnect if the TCP connection is unsuccessful could be produced.
TCP server
Serial-to-Ethernet converter USR-DR302 monitors the set port and waits for a TCP client connection. Data from the serial device is transmitted to all converters successfully connected to the serial Ethernet.
UDP client
USR-DR302 only communicates with the destination interface of the destination IP to ensure the accuracy of the data transmission.
UDP server
After receiving the data, the DR302 can automatically send the data to the device that was last transmitted. This is suitable for devices with multiple networks that need to communicate with the DR301.
HTTP client
DR302 supports the function of transferring the serial data to the specified server in the form of HTTPD (GET / POST).

Application

Power data networking transmission
Small size that is available in the tightest of spaces. The terminal data of the distribution box can be quickly converted into network data. Real-time communication effectively reduces costs.

Unattended weighing
Connect serial to ethernet converter USR-DR302 to barrier gate and it can realize remote control of barrier gate by Ethernet in control center.
