To install NI-DAQ for LabWindows/CVI, run the 

SETUPWIN

 program on Disk 1.  One way to

do this is to select the File menu from the Program Manager Window, then select Run... and
type in 

a:\setupwin

, assuming a: is the floppy disk drive containing Disk 1.  When

prompted, select the Install NI-DAQ for LabWindows/CVI option.

The NI-DAQ example programs for LabWindows/CVI are installed in the 

CVI\SAMPLES\DAQ

directory.

For LabWindows/CVI, the defined constants that several NI-DAQ functions use are in the
include file 

DATAACQ.H

.

After installing NI-DAQ, continue by reading the Software Configuration section later in this
chapter to configure your PC-OPDIO-16.
