Features:
RS485 Port, Industrial Grade
Modbus RTU to Modbus TCP
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.
PC+ABSC material, portable, low cost, V0 flame retardant, ensure the safety of the product.

Working mode
TCP Client
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
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
USR-DR302 only communicates with the target interface of the target IP, thus to assure the accuracy of data transmission.
UDP Server
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 DR301.
HTTP Client
DR302 supports the function of transmitting the serial data to the specified server in the form of HTTPD (GET/POST).

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.
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.
