Function Diagram

Working mode

TCP Client

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.

TCP Server

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.

UDP client

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

UDP Server

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.

Httpd Client

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

Support Modbus gateway

More functions

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

Product details

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

Applications

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-DR302/301 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-DR302/301, 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.
