Connecting passenger flow registration Ш2
sensors
The tracker supports connection of up to 4 Ш2 sensors through 2 discrete-analog inputs
(DAI) IN0, IN1 (
).
Connection order of one Ш2 sensor through resistor to one of DAI of the tracker.
To connect 2 Ш2 sensors to one of DAI use divisor on two resistors. Calculation principle is
realized on voltage level change by sensors triggering.
V – Power supply (battery/ vehicle power supply);
R1, R2 – resistors;
Ш2_1, Ш2_2 – Ш2 passenger flow registration sensors.
Connection order of 2 Ш2 sensors through resistors to one of DAI of the Tracker.
To set an input to count pulses from two sensors one may in the Configurator or by incfg0
3,2,X,X,Y,Y command (where Y – one sensor triggered; X – two sensors triggered).
Parameter X and Y depending on supply voltage and R1, R2 resistors resistance assumes
different values, for example:
U(v)=12, R1=10k, R2=10k, then X=3500, Y=7921
U(v)=12, R1=14k, R2=14k, then X=3000, Y=7000
U(v)=24, R1=10k, R2=10k, then X=7000, Y=15842
