Linear potentiometer has three wires; blue, yellow and brown.
Yellow wire is always connected to any of the eight analog inputs in RaceDAC.
Blue and brown wires; either of them to GND, and the other to +5V Power output in RaceDAC.
There is no polarity limitations with blue and brown wire.
The difference is (with default parameters):
If blue wire is connected to GND: Then numerical output value will be close to 5000 when potentiometer is almost fully compressed.
If brown wire is connected to GND: Then numerical output value will be close to zero when potentiometer is almost fully compressed.
Note: You can achieve the very same "graph vertical flip" -effect with user parameter configurations.
When installing/ calibrating the transducer, be careful to set the stroke so that the output does
not drop below 1% or rise beyond 99% of the supply voltage.
For example:
If your suspension travel is 120mm, then you have (150mm-120mm=) 30mm of "free play".
Divide it into two halves: 15mm and 15mm.
And install the potentiometer so that when suspension is fully compressed; potentiometer could be
compressed additional 15mm/ or when suspension is fully extended; potentiometer could be extended
additional 15mm.
Then potentiometer works in its "mid-range", and will not suffer any mechanical or electrical harm
when suspension bottoms out or tops out.
