3. Software generated instructions

SMS commands can also be generated through software.

After opening the software, open the serial port, modify the parameter configuration, click "Modify", and then on the "Basic Configuration Information" page of the DTU configuration software, click "Generate SMS" to generate SMS commands.

Unique Device ID Number

Each device has a unique ID number for users to use in secondary development. Use your phone to scan the QR code on the device casing or packaging casing to obtain the unique ID number.

Platform Software Description

Juying Cloud Platform is a network platform software developed by our company, which includes mobile APP platform software and web version platform. The mobile APP software includes two categories: Android and IOS. The platform is designed for our company's DAM series network version devices and GPRS version devices, aiming to provide users with remote control output (relay, switch quantity), analog quantity (4-20mA, 0-10V, 0-5V) acquisition, switch quantity acquisition and other services, greatly facilitating user needs. The server is provided by our company, and customers can use it with confidence.

Platform interface

Through the software interface, it is possible to manually and remotely control the opening and closing of the device, view the operating status of the device, input alarm status, and collect real-time data of analog quantities. It is also possible to view the historical curves and data of analog quantities.
Control output interface

Channel name editing

Analog data display

Analog input historical data and curves

The linear setting of analog input and sensor range (such as temperature sensor output of 4-20mA, sensor range of 0-100 ℃) can be converted on the setting interface, and the converted data will be displayed as the actual temperature value collected by the sensor.
