Digital I/O Signal Connections
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.
Warning:
Exceeding the maximum input voltage ratings, which are listed in
Tables 4-1 and 4-2, can damage the VXI-MIO Series module. National
Instruments is
NOT
liable for any damages resulting from such incorrect
signal connections.
Figure 4-9 shows signal connections for three typical digital I/O
applications.
