Introduction of LoRa communication mode:

LoRaWAN communication mode for meter reading and parameter setting.

When reading the meter, you can use the meter data remote transmission software provided by our company to read the meter and set the parameters. According to the power industry standard DL / T 645-2007 (supporting part of the communication protocol), software and hardware systems that fully meet the protocol requirements can be designed for meter reading and parameter setting.

LoRaWAN is a set of communication protocols and system architectures designed for LoRa long-distance communication networks.

When the module is powered on, it automatically sends a join packet. If no reply from the gateway to the network, the join packet will be sent in intervals. After the module receives the network access permission message by the gateway, it pushes a packet of heartbeat data; Since then, it starts timing. Actively push a pack of heartbeat data at intervals of 6 hours.

 

LED indicator:

LED from left to right in sequence are indicating

-Pulse (RED color);

-Power supply and credit status(bi-color, normal status in GREEN, low credit status in RED and blinks);

-Alarm / Tampering (YELLOW color).
