6.1 Analogue inputs
The analog inputs IN0 and IN1 can be used to connect analog type sensors and voltage
measurement, and can also be interpreted as discrete.
Voltage measurement range: 0...58.8 V.
Discreteness (sensitivity): 57.4 mV.
Minimum input resistance: 200 kOhm.
It is forbidden to apply voltage exceeding the upper limit of the measuring voltage range
If it is necessary to record a certain voltage level, for example, in the ignition switching circuit,
activate discrete operation mode and set values of voltage level for the logical “1” with the
INTRUE
and for the logical “0” with
INFALSE
Description of the commands:
INFALSE IN, X0, Y0
IN - number of the analog input (always specify 0)
X0 - the lower limit of the logical "0" voltage range (fixed value 0mV)
Y0 – the upper limit of the logical "0" voltage range (variable value)
INTRUE IN, X1, Y1
IN - number of the analog input (always specify 0)
X1 - the lower limit of the logical "1" voltage range (variable value)
Y1 - the upper limit of the logical "1" voltage range (fixed value of 60000 mV). When entering
these commands, the voltage must be specified in millivolts.
If the voltage level is in the zone of indifference, the previous discrete state is maintained until
the level goes beyond the zone of indifference.
The measured voltage levels are registered by the tracker and transmitted to the server.
When changing the discrete state, an extraordinary packet is sent.
