The minimum input resistance: 110kOhm.
If the voltage level in a given circuit does not exceed 6,6 V or 13,3 V, it is recommended to
use IN0 or IN1to enhance readings transmission accuracy.
It is prohibited to supply voltage to the input if it exceeds the upper measurement range
threshold by more than 20%.
The current voltage value in the analogue input is displayed in response to the «
INPUT
»
command.
When it is necessary to smooth the measured voltage fluctuations, it is possible to set the
time of readings averaging by th
e «
IN
FILTER»
command.
When there is a need for recording the fact of a certain voltage presence, for example, in the
ignition activation circuit, it might be necessary to set for the selected analogue input voltage levels
for the logical “0” by the «
INFALSE
» command and for the logical “1” by the «
INTRUE
» command
Commands description:
INFALSE IN, X0, Y0
IN
– number of the analogue input
X0
– the lower logical 0 range threshold
Y0
– the upper logical 0 range threshold
INTRUE IN,X1,Y1
IN
– number of the analogue input (0 or 1)
X1
– the lower logical 1 range threshold
Y1
– the upper logical 0 range threshold

— Discrete states ranges
If the voltage level is in the indifference zone, the previous discrete state will be saved until
the level is beyond the indifference zone.
The measured voltage levels values are registered by the tracker and transmitted to the
server in the data block IN_A with a common periodicity.
