Din Rail RS485 Industrial cellular Modems
Provide data two-way transparent transmission between
field serial devices and the central control server
Support 2 Socket connections, support TCP Client and UDP
Support custom heartbeat package and registration package
submit serial data to the designated server by HTTP (GET/POST) method
Modbus RTU/Modbus TCP protocol conversion for
industrial SCADA systems and field devices.
The registration packet is sent to the server to identify the device.
The heartbeat packet is used to judge the active state of the device when sent to the server,
and actively collect data when sent to the serial terminal.
The contents of registration package and heartbeat package,
heartbeat interval can be modified by AT command.
Support AT command setup by serial port,network ,
SMS and provide configuration tool for PC(windows).
With the remote management platform,it can realize the automatic
firmwareupgrade.The difference algorithm upgrade package is small,
saving upgrade traffic and time
Level-3 ESD protection, level-3 surge protection, and built-in hardware watchdog
Convenient cabling for installation, less space usage,
and ease of use with other products.
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.

Application to Electric Fire Monitor SystemMay 18,2020
The cellular modem can be used in electrical fire monitoring system. In this application, we will introduce how to use industrial modem USR-G781 and industrial modem USR-DR504 in the electrical fire monitoring system.
Intelligent Remote Distribution Box Monitoring SolutionJun 10,2021
The distribution box is embedded with the DTU distribution device, distribution device power module, and distribution device power supply. By leveraging the intelligent remote monitoring function, you can remotely collect the electric meter readings and implement networked transmission. In addition, with the help of electricity monitoring platform of USR Cloud, you can manage and control the electricity safety and electric energy over the cloud.
