Position Sensors
Different position sensors/potentiometers can be connected to Daqu in order
to provide control position information for one of the following functions:
pitch trim,
roll trim,
flap position,
throttle position,
and some others.
These sensors are usually potentiometers (variable resistors) with different
ranges. Daqu supports ranges of 400 Ω, 5 kΩ and 10 kΩ.
Potentiometer can be connected as variable resistor or variable voltage. Refer
to the potentiometer datasheet for pin identification.
Connection schematics for both cases are given in section 3.7 starting on page
20. Here, configurations are shown for both cases.
4.11.1
Variable Resistance
Figure 11 shows typical schematics for the variable resistance. The corre-
sponding channel is configured something like shown by Table 15.

Table 15:
An example configuration for pitch trim resistive sensors.
Similar configuration can be used for flaps, various positions and other trim
functions.
