PCI-69222 Analog Input
Channels 0~15. Each channel
pair, AI<i, i+8> (I=0..7), can be
configured as either two single-
ended inputs or one differential
input pair (marked as AIH<0..7>
and AIL<0..7>).
PCI-69223 Analog Input
Channels 0~31. Each channel
pair, AI<i, i+16> (I=0..15) can
be configured as either two
single-ended inputs or one
differential input pair (marked
as AIH<0..15> and AIL<0..15>).
AISENSE AIGND Input Analog Input Sense. This pin
serves as reference for any
channels AI<0..63> in NRSE
input configuration.
