DIN-Rail RS485/RS232 to Ethernet Converters USR-DR302/301 can transmit data transparently between TCP/IP and RS485/RS232, which are widespread required in industrial automation.

Realize bidirectional transparent transmission
between RS485/RS232 and Ethernet


Small size, easy to manage and maintain, cost-effective


Serial to Ethernet converter USR-DR302/301 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.

Serial to Ethernet converter USR-DR302/301 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.

USR-DR302/301 only communicates with the target interface of the target IP,
thus, to assure the accuracy of data transmission.

DR302/301 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 DR302/301.

DR302/301 supports the function of transmitting the serial data to the
specified server in the form of httpsD (GET/POST).


Virtual serial software
Solve the problem of PC software
as a serial port cannot 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 302/301 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

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

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.

Connect serial to ethernet converter USR-DR302/301 to barrier gate and it can realize remote control
of barrier gate by Ethernet in control center.

Connect serial to Ethernet converter USR-DR302/301, 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.
