  • 1. Getting Started

    The article provides a comprehensive guide for connecting a device using a Type-C cable and configuring LoRaWAN network communication parameters, including network access modes, basic settings, and data acquisition configurations to optimize device performance and integration.

    2. Example-Analog Input (AI)

    Use an analog soil sensor, connect it to the AI1 pin of the control terminal, and then click the "Read" button (if VOUT is used for power supply, the 12V power output needs to be turned on).

    3. Example-Digital Input (DI)

    Use DI1 for level demonstration and DI2 for counting demonstration.

    4. Example-RS485

    The article provides a detailed guide on integrating RS485 with LoRaWAN, including hardware and software preparation, connection instructions, and configuration settings required to achieve optimal results with DFR1120-915 control terminal and soil sensors.
