DATA COLLECTION AND TRANSMISSION ALGORITHM
Data are read from a control and measuring device with a configurable period of 1 minute
(it is not recommended to set the measurement frequency to less than 1 minute to ensure a long
non-volatile mode of operation). The read data are stored in the switching device memory and
transmitted at a predetermined discrete session with the LoRaWAN network.
The data transmission period can be configured from 1 minute. By default, the manufacturer sets
the data transmission frequency to 1 time/hour. The data is transmitted on the specified timer,
which is installed in the internal memory of the switching device.
The switching device operates from a 3-5V DC power supply or a built-in power supply.
The 14A/h power cell capacity is designed for operation life according to the table:

If the Request Confirmation parameter is enabled, the switching device will send the next
package only after receiving delivery confirmation of the previous package. If you do not receive
such an acknowledgement after three replays, the switching device ends the session until the
next scheduled session. At the same time, the switching device stores the untransmitted data to
the memory. Non-transmitted packages remain in the switching device memory and are sent
during the next communication session.
If the Request Confirmation parameter is disabled, the switching device sends the current data
to the network with the specified frequency. There is no package delivery check in this mode.
Untransferred packages do not remain in the switching device memory.
The communication time of the switching device is controlled by the LoRaWAN network server
and can be adjusted by command.
FUNCTIONALITY
The switching device is designed for operation with the following control and measuring devices:
•
Pressure sensors;
•
Temperature sensors;
•
Level sensors;
•
Vibration sensors;
•
Gas sensors (gas analysis);
WARNING
: The switching device is equipped with a built-in power cell - a
non-rechargeable lithium-thionyl chloride (LiSOCL2) battery.
Attempts to
charge the battery can cause fire!
