23.5.12 GP (General Purpose) Inputs
These inputs are configured by the GDU (refer to
32.4.25 for GDU 45X/46X systems) and are capable of reading any voltage up to 40 Vdc. The GEA 24
has 7 position inputs, labeled POS 1 through 7, and 7 general purpose inputs, GP 1 through 7 (to limit the
length of pin names, "GPX" is not used on all pins), each of these are paired together.
Potentiometer based sensors can be used by connecting the potentiometer across a +5 V supply and ground
and reading back the center tap voltage on GP1-G7/POS1-7. Some General Purpose inputs have multiple
functions.
