AOGND is the ground referencesignal for both analog output channels and
the external reference signal. Figure 4-9 shows how to make analog output
connections to your device.
Figure 4-9. Analog Output Connections
Digital I/O Signal Connections
All Devices
All devices have digital I/O signals 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 as inputs or
outputs. Figure 4-10 shows signal connections for three typical digital I/O
applications.
Caution
Exceeding the maximum input voltage ratings, which are listed in Table 4-2, can
damage the DAQ device and the computer. National Instruments is not liable for any
damages resulting from such signal connections.
