Choose EU868 band, Click “connect “and “Yes”.
pls send this command 'WIRELESS_MKEY:20210604' as following picture (for HV:82,SV:2A
version).
Step 3:
Hold a magnet close to the red area shown in Figure 2-1. Within 4 to 9 seconds, remove the
magnet and PULSE915-LRW will enter configuration mode. Importantly, the magnet
provided is a strong magnet, hence the magnet needs to be removed out of the area as the
defined time range for the specific function, otherwise, PULSE915 will continuously be
triggered and automatically enter to the other mode.

The reed switch inside the product is triggered by a magnet to put the device into
configuration mode, then a configuration command is required to send within 30 seconds.
If the product does not receive a configuration command in 30 seconds, it will exit the
configuration mode. A configuration command will keep device in configuration mode for
another 30 seconds.
The trigger position is shown in Figure 2-1.

Step 4:
In configuration mode, various commands can be set for PULSE915-LRW through the
configuration software. For example, clicking on various query buttons returns the
corresponding value.
Parameters such as initial meter index data, pulse weight, clock, sensor type and
measurement mode can be configured in “Metering parameter” page. We just need to click
the corresponding button on the right to set the parameters.
The sensor type is “Hall” and “Reed Switch”, and measurement mode is “Single pulse” and
“Double pulse”. Users can set parameters according to the sensor type and pulse output
type of actual device that PULSE915-LRW connected.

need to click the corresponding button on the right to set the parameters.
Data report time o’clock in minutes can be set according to customer requirements. For
example, set as 1440 minutes that indicates 24 hours.
Reporting supports “default curve”, “custom curve”, “Long frame mode” and “Short frame
mode”. Users can choose the required data format.
If the frequency is set to US915, since the LoRaWAN protocol limits the number of reported bytes, the
“Report data mode” must be set to “Short frame mode” under the “Other parameters” tab. For other
frequencies it can be arbitrarily selected as “Long frame mode” or “Short frame mode”.

2.5 Curve Frame Configuration Guide
The Pulse 915-LRW divides a day into 96 time points evenly, and the interval between time
points It is 15 minutes, as shown in the table below.
The user can set any desired data collection plan by modifying the 12-byte mask. The mask
corresponding to the above figure is FFFF8888888888888888888F. The mask can be
obtained through the separately provided data collection schedule.
The steps to get the mask are as follows:
1. Set the time point that needs to be reported to 1, and the time point that does not
need to be reported to 0.
For example:

PULSE915-LRW Configuration Guide
Page 19 /27
2. The currently selected report points, mask, and AT commands are displayed in the
lowermost area.
Due to the limitation of the data length of the LoRaWAN protocol, a maximum of 77 data
collection points are currently supported. If the collection point set by the user exceeds 77,
the mask and AT command will not be displayed.
The data collection schedule can be get from FRIENDCOM.
