Realize bidirectional transparent transmission
between RS485 and Ethernet
Small size, easy to manage and maintain, cost-effective
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
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.
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
Power data networking transmission
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.
