Hardware Setup Changes After
Removing a Card
In this case, the Hardware Setup dialog will re-
flect the change to the installed I/O cards. The
remaining inputs and outputs will function nor-
mally.
For example, if you remove the Analog Input
card, the Analog Input tab will disappear from
the Hardware Setup dialog.
You will lose the configuration of any pairs of
inputs or outputs that were assigned to the card
being removed.
