INPUT:POLARITY

The input polarity command selects the input polarity for one or more channels. When a channel is programmed for normal polarity, an interrupt will be generated when the input voltage is greater than the programmed input offset for the channel. The invert polarity will cause an interrupt when the input voltage is less than the programmed input offset for the channel.

INPut:POLarity <polarity>,<channel_list>	Where <polarity> is either NORMal or
	INVerted
	Where <channel_list> is the standard
	channel list format supporting channels 1
	through 16.

EXAMPLES
INPut:POLarity NORM,(@3:5)	Sets the input polarity for Channels 3
	through 5 to NORMal. This will generate
	an interrupt when the input signal on
	Channels 3, 4 or 5 is greater than the input
	offset.
INPut:POLarity? 5	Returns the input polarity for Channel 5 as
NORM	NORMal
INP:POL INV,(@6)	Sets input polarity for Channel 6 to invert.
