1Introduction
This document provides operating, maintenance and installation instructions .
The unit measures and displays the characteristics of single phase two wire(1p2w) , single phase
three wire(1p3w), three phase three wire(3p3w,) and three phase four wire(3p4w) supplies,
including KWh, kVArh, kW, kVAr, kVA, PF, Frequency, Voltage, Current, dmd. THD etc. Energy is
measured in terms of kWh, kVArh. Maximum demand current can be measured over preset
periods of up to 60minutes.
The requisite current input(s) are obtained via current transformers (CT). This meter can be
configured to work with a wide range of CTs, giving the unit a wide range of operation.
Configuration is password protected.
This unit has a built-in LoRaWAN module which allows long range wireless communication. Two
pulse outputs are available for real time energy measurement.
1.1 Unit Characteristics
The Unit can measure and display:
Line voltage and THD% (total harmonic distortion) of all phases
Line Frequency
Currents, Current demands and current THD% of all phases
Power, maximum power demand and power factor
Active energy imported and exported
Reactive energy imported and exported
The unit has password-protected set-up screens for:
Changing password
Supply system selection 1p2w, 1p3w, 3p3w, 3p4w
Demand Interval time, backlight time
Reset for demand measurements
Pulse output type/ duration
Current inputs correction
1.2 CT Ratio
The unit can be configured to operate with different ratio of CTs. The Primary current can up to
9999A. The secondary CT has two options: 1A/5A
1.3 Pulse outputs
The unit provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total/
import/ export kWh or kVArh.
The pulse constant can be set to generate 1 pulse per:
0.01 = 10 Wh/VArh
0.1 = 100 Wh/VArh
1 = 1 kWh/kVArh
10 = 10 kWh/kVArh
100 = 100 kWh/kVArh

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.

The format of standard LoRaWAN is shown below:
The following description of the text is defined the data in the segment of FRMPayload region in
LoRaWAN protocol. The software in PC only need to get this part of data from gateway. According
to the following protocol definition to parse the data.
The data format and encoding of meter communication protocol are modified based on the
Modbus ASCII transmission mode. Remove the start and end characters from the Modbus ASCII
transmission mode and change LRC validation to CRC validation.
Encoding of data: communication data is encoded with ASCII, and each byte of data is sent with
two ASCII characters.
E.g.: a byte data 0x5b is encoded as two characters: 0x35 and 0x62 (ASCII code 0x35= "5", 0x62=
"b")
Command format definition:
I: The data format of the gateway sending the copy command:
Reserved Function
Code
The first Address of The
Register to Read Data
The Number of Registers
to Read Data
CRC Check
Codes
1byte 1byte 2byte 2byte 2byte
Note: the reserved bit is fixed as 0x01
II: the data format returned by the meter after receiving the copy command:
Reserved Function
Code
The Length of
Data Returned
Specific Data Returned by The
Meter
CRC Check
Codes
1byte 1byte 1byte N byte 2byte
Note: the reserved bit is fixed as 0x01
III: Note: the above commands need to be ASCII, so 1byte data will have 2 characters.
E.g.
1). Suppose to read the current data of the meter L1, the data sent by the gateway is the ASCII
coded data as shown in the following table:

Note: the first address of the register of the meter L1 current is 00 06 and the number of registers
is 2.
2) After receiving the above command, the meter will return the current L1 current data of the
meter, as shown in the following table after ASCII coding.
Note: Assume that the current meter's L1 current is 5.0A, since the data is in floating point
format, the Hex data is converted to 0x40, 0xa0, 0x00 and 0x00.
To ensure the successful communication, below information must be confirmed:
1. The command is sent through Class C mode.
2. The command is sent in ASCII format.
2. Start Up Screens
The first screen lights up all display segments and
can be used as a display check.
