LTE-modem signal quality is from 0 to 31 when there is a connection, but 99 value
means that there is no connection. See details in the table below.

“ Force compose packet ” button – by pressing the button the device collects readings
from all interfaces, forms the packet and put it in the black box.
One Wire – the settings of connection any external temperature sensors and its
readings. For adding a temperature sensor, you should to switch the auto adding mode on.
Every sensor will get a number in order it was connecting. After switching the auto adding
mode on, the device search for some new sensors on the bus. If there is a sensor then the
device adds it in memory and switch the auto adding mode off. To add the next sensor, you
should to switch the auto adding mode on again. All sensor removed from the device
memory by pressing the button
“ Delete all sensors ” .
Interface settings – allows setting up the type of every input – it may be pulse or
security mode.
Guard settings – allows setting up the work of security inputs, namely, what kind of
security circuit state is reason to send an alarm message: short, open, or both.
Connection settings – a group of parameters that allows you to configure the collection
and transmission periods, and the time zone for the internal clock and choose the technology
of data transmitting and LTE-modem mode.
Wireless technology to use – LTE or LoRaWAN technology of data transmitting.
MQTT over LTE settings – setting for connection through LTE-modem.
“ Force MQTT connection ” button – by pressing the button the device initiate
extraordinary communication session through MQTT broker.
Modbus – the part contents settings for data reading via MODBUS protocol from the
external device connected to SH-2 through RS-485 interface.
The readings are read from the connected device at 00.00 on the internal clock of the
device if the data collection period is set to 24 hours, at 00.00 and at 12.00, if the period is 12
hours and so on. All readings are stored in the device memory until the next communication
