DR Series

DIN-Rail series launched by Jinan USR IOT Technology Limited, include
Serial to Ethernet converters, 4G LTE Cat 1 modems and 4G industrial
routers. Their built-in 35 mm DIN rail seat apply to all DIN-Rail installation
scenarios. USR-DR502-E is shown as following

Product Details

PC+ABS materials, compact, low cost; flame retardant grade V0,
ensuring the safe use of the product

DIN-Rail mounting

Convenient cabling for installation, less space usage,
and ease of use with other products

Basic Functions

Support the RS485 serial port, and easily deliver the data transparently
between RS485 and 4G LTE Cat 1 network in bi-direction

Operation Mode

Transparent transmission mode

Support the four sockets connection, TCP client and user datagram protocol (UDP).
Support the customized heartbeat package and registration package functions.

HTTPD Mode

Support the submission of serial data to the designated server
in HTTP (GET/POST) mode

Parameter Configuration

Support the parameter configuration of serial, network and SMS commands,
and provide the configuration tool for the PC.

FOTA Remote Upgrade

With the remote management platform, it can realize the automatic
firmware upgrade The upgrade package of difference algorithm is small,
and the upgrade traffic and time are saved

Hardware Protection

Level-3 ESD protection, level-3 surge protection, and built-in hardware watchdog

Application Case

Data Collection of Distribution Boxes
By virtue of its small size and DIN-Rail installation, USR-DR502 can be installed in
a low voltage distribution box to save space. With extremely fast response speed,
4G DTU device can timely send data to the control platform.
