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

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

More Functions

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
