Analogue-to-
digital Gain
Analogue-to-
digital gain is very useful when
connecting a potentiometer externally. It may adjust
input or output channel gain. It looks like a rotary
encoder. The difference between them is that a
potentiometer is analogue
and adjusts voltage and
current while an encoder is digital and transmits
binary codes of 0 and 1.
Output GPIO Setting
Preset
Output types: High level / Low level
Preset: Corresponding GPIO port outputs high level
