Figure 2-2 shows the relationship between LabVIEW, NI-DAQ, and
DAQ hardware.
Figure 2-2.
How NI-DAQ Relates to Your System and DAQ Devices
(NI-DAQ 4.8.
x
for Macintosh)
NI-DAQ 4.8.
x
for the Macintosh device drivers
are bundled in a single file that determines which drivers to load. When you
restart your computer, this control panel driver, called
NI-DAQ
, determines
which devices are installed in the system and loads their corresponding
drivers. NI-DAQ uses its control panel settings to determine what
SCXI hardware is configured and what the default device settings are for
devices in the computer. If you use DMA, NI-DAQ also communicates
with the NI-DMA/DSP for DMA services. When you install LabVIEW,
the installer places both of these files on your hard drive.
(NI-DAQ 6.0 for Macintosh)
The NI-DAQ Driver, called
NI-DAQ
is installed
in the
National Instruments
folder in your Macintosh
Extensions
folder.
(NI-DAQ 5.
x
, 6.0 for Windows)
The NI-DAQ Driver, called
NIDAQ.DLL
in
Windows 3.
x
and
NIDAQ32.DLL
in Windows 95/NT, is installed in your
Windows system directory.
