The external reference signal can be either a DC or an AC signal. The
board multiplies this reference signal by the DAC code (divided by the
full-scale DAC code) to generate the output voltage.
The digital I/O signals are DIO<0..7> and DGND. DIO<0..7> are the
signals making up the DIO port, and DGND is the ground reference
signal for the DIO port. You can program all lines individually to be
inputs or outputs.
Exceeding the maximum input voltage ratings, which are listed in
Tables 4-1, 4-2, and 4-3 can damage the PCI E Series board and the
computer. National Instruments is
from such signal connections.
