USR-DR302 DIN-Rail Modbus RS485 Serial Port to Ethernet Converter Bidirectional Transparent Transmission Between RS485 and RJ45

Features:
RS485 port, industrial grade
Modbus RTU to Modbus TCP
Virtual Serial Software: Solve PC software problem because a serial port cannot communicate with the peripheral network.
Network Heartbeat Packet: The serial server maintains the normal connection to the server by sending a heartbeat packet regularly.
PC + ABSC material, portable, low cost, flame retardant V0, ensures product safety.

Operating mode
TCP Client
The USR-DR302 Serial to Ethernet Converter will initiate TCP connection to the user-configured destination IP address and the serial to Ethernet converter will continuously try to reconnect if TCP connection fails.
TCP Server
The USR-DR302 Serial to Ethernet Converter monitors the defined port and waits for a TCP client connection. Data from the serial device will be transmitted to all those who are successfully connected via a serial to Ethernet converter.
UDP Client
The USR-DR302 communicates only with the target interface of the target IP address, ensuring the accuracy of data transmission.
DR302 can transmit the data automatically to the last transferred device after receiving the data, which is suitable for multi-network devices that need to communicate with the DR301.
HTTP Client
DR302 supports the function of serial data transmission to the specified server in the form of HTTPD (GET/POST).

Application
Power Data Network Transmission
Small size which is available for narrow space; DIN rail mounting, easy to install on the wall; Terminal data of distribution box can quickly be converted into network data, real-time communication, reduce costs efficiently.
