NOVUS AUTOMATION 6/8
The table below relates the values obtained in the reading of the LQI to the
evaluation of the quality of the signal. The same information can be viewed in a
more intuitive way in the tab DigiConfig Software Diagnosis.

NOTE: The model described in the graphic takes in consideration the
propagation channel only. LQI may vary due to several factors, such as due
to peripheral obstacles such as trees, buildings, hills that interfere in the
propagation channels as explained by the Fresnel Zone phenomenon.
REGISTER 29 – BATTERY POWER
It has the value of the measurement of the battery power’s level in an
engineering unit. The decimal point is fixed in three places, the value has no
point and must be provided in the reading software.
A fully charged battery typically has a power above 3.6 V. As you use the
RHT-Air, the power of the battery will gradually decrease. It is
recommended that you check the value of this register regularly so that
when it reaches below 3.3 V, the battery can be replaced.
The verification of the capacity of the battery can be done through the
DigiConfig Software Diagnosis tab, which will display an icon. The evaluation
of battery capacity can be done according to the criteria presented below:

3500 to 3700 Great
3400 to 3500 Very Good
3300 to 3400 Good
3200 to 3300
Average – Get ready
to replace your
battery
Lower than 3200
Bad – Replace the
battery as soon as
possible
NOTE 1: Even when the power is below 1100, the equipment will operate
normally.
NOTE 2: The gradual failure of the battery’s power is not linear, therefore,
though the equipment is able to continue working under tensions below 3.0V,
when it reaches this level, there is little left for its life, since the power will fail
more quickly.
NOTE 3: When the equipment is being supplied by an external power source,
the value presented represents the power supply of the circuit after the power
regulator reaches 3.6 V. This value may vary according to the setting’s
conditions, but should not be lower than 3.3V.
NOTE 4: The machine’s operating temperature has a significant impact on
the battery’s capacity. Temperatures below 0 °C will typically shorten the
battery’s life.
NOTE 5: The update time, as well as the operating power, have a significant
impact on the battery’s capacity. If the equipment is configured for the lowest
update interval, the battery will typically last less. The same happens when
the equipment is far from the AirGate-Modbus with which it should be
matched, needing a higher transmission power to operate.
REGISTER 30 – LAST POLL’S DURATION
Every time the RHT-Air publishes something on AirGate-Modbus, this
register gets a zero value. Every 100 ms, this register is increased in one
unit in order to indicate how long it has been since the last publication.
REGISTER 31 – MODBUS
It sets the address of the equipment on the Modbus network. This address
identifies the equipment on the Modbus network. Its configuration may range
from 1 and 247, and it should be stressed that there cannot be more than
one piece of equipment with the same address on the same network. RHT-
Air is originally manufactured with the address 246. When connected to a
USB interface, it always responds to Modbus functions through the address
246 to a BaudRate 115200 that has no parity and with 2 Stop Bits. When it is
in operation, it always responds through the address it was configured for in
this register according to the communication parameters of the Modbus
network on which it was installed.
REGISTER 32 – UPDATE TIME
It sets the configuration for how often the equipment wakes to publish
information on the AirGate-Modbus with which it is matched and update the
IHM screen.
The shorter the update time, the more recent the data available to the
master of the Modbus network will be, but the higher the energy
consumption spent and the battery's life will be proportionately shorter. On
the other hand, the higher the update time set, the lower the energy
consumption spent will be, thus providing a longer life for the battery.
REGISTER 33 – INDICATION MODE
It sets the mode of indication of the values read on the display. The
equipment is originally manufactured with the indication of temperature and
relative humidity.
CODE DESCRIPTION
0 Indicates the temperature and relative humidity.
1 Indicates the temperature and dew point.
2 Indicates relative humidity and dew point.
3 Indicates the temperature only.
It has the value of the measurement in an engineering unit. The decimal
point is fixed in one place, the value has no point and must be expected for
the reading software.
REGISTER 34 – CONFIGURATION OF THE MEASUREMENT UNIT
It sets the measurement unit for both temperature and dew point. The
equipment is originally configured in (ºC).
CODE UNIT
0 ºC
1 ºF
REGISTER 35 – DISABLES CONFIGURATION THROUGH A BUTTON
It sets the alteration of configuration through a button.
CODE DESCRIPTION
0 Original standard value.
1
Disables the alteration of configuration of communication
parameters through a button.
REGISTER 36 – USER OFFSET DE FOR TEMPERATURE
It sets the user’s offset value in engineering units for temperature. The
equipment’s offset value is originally zero.
REGISTER 37 – USER OFFSET DE FOR HUMIDITY
It sets the user’s offset value in engineering units for relative humidity. The
equipment’s offset value is originally zero.
REGISTER 38 – ERROR VALUE
It contains the error value that is transmitted when the sensor has a problem.
The equipment's original value is -9999.
