Compact Industrial
Serial to Cellular Modem
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.
Registration Package plus Heartbeat Package
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.
Parameter Configuration
Support AT command setup by serial port,network ,
SMS and provide configuration tool for PC(windows).
Remote FOTA Upgrade
With the remote management platform,it can realize the automatic
firmwareupgrade.The difference algorithm upgrade package is small,
saving upgrade traffic and time
Hardware Protection
Level-3 ESD protection, level-3 surge protection, and built-in hardware watchdog
DIN-Rail mounting
Convenient cabling for installation, less space usage,
and ease of use with other products.
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.
