OY1410 Pulse meter manual
This manual offers a simple 5-step guide for getting started with the sensor, as well as
configuration with Talkpool’s Sensepool visualization layer and information for advanced
users.
The OY1400 Industrial communication and control unit is designed with focus on ease-of-use
and reliable operation in LoRaWAN networks. The product is dedicated to be used together
with BMeters’ IWM sensor. Normal users will only need to read the 5-step guide at the
beginning of this manual.

Digital activation
Standard devices are configured to use OTAA (Over The Air Activation). It is possible to
order a batch of devices configured for ABP (Activation By Personalization).
Standard devices are configured with the AppEUI (a.k.a. JoinEUI) 70-B3-D5-D7-2F-F8-14-
02. It is possible to order a batch of devices configured with a customer unique AppEUI from
the Talkpool OUI.
Upon receiving your OY1400 Industrial Control and communication unit you should first
provision it to your network server. The product comes with the following:
1.! Dev EUI (also can be found on the outside of the unit)
2.! App Key
These codes are unique for each sensor. The Dev EUI can be seen as a simple identification
code, the App Key is a securely generated authentication code.
The first step you should take is to simply provision the network server, this can be
Talkpool’s solution called Sensepool or any other system that you would like to integrate the
sensor with, with your App EUI.
The second step is to provision the application server with your unique Dev EUI and App
Key.
Digital activation process
After the digital activation the sensor has to be physically activated and installed.

Physical installation
When the sensors have been digitally configured it is time to physically activate and install
them. The OY1410 is dedicated to use together with BMeters’ IWM-PL3 or IWM-PL4 units.
First install and configure the IWM-PL3 or IWM-PL4 unit according to BMeters’ instruction.
It is important to configure it according to the table below:
Setting
Value
K index
Set depending on watermeter, see table below
Pulse ratio X
Set to same a K-index
OUT3
Absolute count
Pulse length
80
The K-index and Pulse ratio X defines the number of liters per pulse. It is important that the
Oy1410 is configured with the same setting. The table below shows the settings for different
watermeter models:

Open the OY1410 using a screwdriver. Replace the right cable gland with the supplied blind
plug. The enclosure has two openings that can be used for wall mounting.
The cable from IWM-PL3 and IWM-PL4 has four wires. Cut the white wire since it will not
be used and might cause short circuits if it is left unconnected inside the OY1410. Feed the
cable though the left cable gland.
Connect the IWM-PL3 or IWM-PL4
according to the table below as illustrated
by the picture to the right.

Make sure that both jumpers are set to 0-10V as illustrated by the picture below.
After that you install the (replaceable) batteries,
which activates the unit, you close the box and
start measuring your data!

Function description
The OY1410 counts the pulses output by the IWM-PL3 or IWM-PL4. The corresponding
water volume depends on the set “Pulse ratio X”-value in the IWM-PL3 or IWM-PL4, which
in turn depends on the type of water meter used. To get the OY1410 to report water volume in
liter it is required to set the IWM Pulse Ratio to the same value as Pulse Ratio X in the IWMPL3 or IWM-PL4.
The OY1410 also supervises the fraud signal from the IWM-PL3 or IWM-PL4. If a fraud
condition is detect based on the output from the IWM unit the fraud detection indicator in the
LoRa uplink message will be set in coming reports until the fraud detection indicator has been
explicitly cleared using a LoRa downlink request.
The OY1410 also detects if the batteries are replaced, since it will not be able to count the
pulses from the IWM-PL3 or IWM-PL4 while the batteries are not inserted. When the
batteries have been replaced the reset detection indicator in the LoRa uplink message will be
set in the coming reports until the reset detection indicator has been explicitly cleared using a
LoRa downlink request. Note: The reset signal is also set during the first startup.
It is possible to set the counter value in the OY1410 to a preset value using a LoRa downlink
request.
