1000=1000 kWh/kVArh
Pulse width: 200/100(default)/60ms.
Pulse output 2 is non-configurable. It is fixed to total kWh. The constant is 3200imp/kWh.
1.4. LoRaWAN Classes
Eastron LoRaWAN energy meter is implement Class C functionality. The device will upload
message after receiving the data sent from the network.
1.5 Active Upload Mode
The device also can be customized to active upload mode. Total 30 parameters can be set for
automatic uploading.
Interval time can be set from 0 to 255 through communication. 0 means the function is OFF. If
there are many parameters, the interval shouldn’t be set too short in case of conflicting on data
uploading.
The meter will upload automatically once it joins the network. And after the interval time, it will
upload again.
The interval time is calculated since the last data uploading. Sometimes the interval time may
have around 1-2 minutes difference due to the timer error.
1.6 Join
The unit uses standard LoRaWAN protocol for long range communication. Before Communication,
the meter has to join the LoRaWAN network first.
There are two Activation Ways for Joining: OTAA(Over-the-Air Activatioin) and ABP(Activation by
Personalization).
To ensure the meter join gateway successfully, below information must be confirmed:
I. DevEui, AppEui, Appkey or DevAddr, NwkSKey, AppSKey information are correctly recorded into
the gateway.
II. The Uplink and downlink frequency are same as the gateway.
III. RX2 (frequency and SF) information are same as the gateway.
If the Join delay function is ON, the meter will join the network with a few seconds delay by
random.
1.7 Communication
LoRaWAN meter communicate based on international general purpose protocol. The
communication data is placed in data segment of LoRaWAN protocol, they will be appointed
follow the specified command format.
