rings. If necessary, support the radio module by holding it in place with your other hand at the same
time when pulling out the measuring module.
To join them, align the small, embossed arrowheads on both modules’ housings (when they are
aligned, also the labels on both modules are on the same side). Then push the measuring module
straight into the radio module until the locking latches catch and click into place. The indicator led will
blink shortly after the radio module is detected successfully. Note that, the blink may happen several
minutes after the joining due to the power saving feature of the detection algorithm. The radio module
should be detected and in operation within 10 minutes from the joining.
Opening the measurement module
Opening the module is necessary only for wiring the internal connector on the
ES model.
•Detach the measurement module from the radio module.
•Use a large flat-bladed screwdriver to push the measurement module
cover off via the rectangular hole (see picture).
•Pull the circuit board out.
Assemble reversely, taking care that the circuit board sits on the grooves.
Power supplies
The measurement modules are powered with a 3.6V Lithium Thionyl battery pack. The modules are
supplied with the battery pack already installed. The radio modules are powered by the measurement
module.
Wiring
The wiring of the sensor connector is described in the chapter for each module, where applicable.
Configuring
The default configuration should be sufficient for most of the applications. The connected sensor needs
to be configured for the CS and ES models and the non-provisioned versions need LoRaWAN
parameters, such as activation keys. To view and change the configuration:
1. Detach the modules.
2. Connect a micro-USB cable to the connector in the measurement module, and the other end of
the cable to a computer.
3. Launch the Mekuwin program (available for free at www.nokeval.com).
4. In Mekuwin, choose the correct port. If the port is not visible, try to reconnect the cable to the
computer
5. Choose Protocol = Modbus, Address = 1.
6. Click Direct.
7. A new window will open. It has branches for different settings.
8. Adjust the settings, and finally click Save to EEPROM.
The exact contents of the menu depend on the module type. The applicable settings are described in
the corresponding chapters. The common settings for all the modules are:
Period: Select the measurement interval in seconds. An unnecessarily short interval will consume the
battery and the radio band. Default 900 s.
Quality: Select the reliability of the radio packet delivery:
