    3. Function Description

       3.1 Metering Function

    DC measuring device sampling by shunt with high accuracy, which can measure DC energy, current,voltage.

     

    3.2 Communication Function

    NB-IOT communication with protocol 376.1, which can realize remote communication with low consumption and strong penetrability.

     

    Supports RS485 communication with protocol DTL645, which allows parameters setting and read or write power data of downside devices.

    Upgrade locally through RS485.

    Upgrade remotely through NB-IOT.
