USR-DR302 Modbus RS485 to Ethernet converter can realize bidirectional transparent transmission between RS485 and Ethernet. Via web-page or software, rs485 to Ethernet Converter can realize serial data and TCP/IP data package transparent transmission.

Realize bidirectional transparent transmission between RS485 and Ethernet

DIN-rail mounting: Small size, easy to manage and maintain, cost-effective

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

SKU: USR-DR302-E

Function Diagram

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 DR302.

Httpd Client

DR302 supports the function of transmitting the serial data to the
specified server in the form of httpsD (GET/POST).

Support Modbus gateway

Product details

PC+ABSC material, portable, low cost, V0 flame retardant,
ensure the safety of the product.

Appliaction

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.

Traffic Lights Management System

Connect serial to Ethernet converter USR-DR302, and it can realize traffic data acquisition and processing by Ethernet in the control center. And the control room personnel can quickly make traffic scheduling and planning according to the site condition.
