How To Use the Manual Set
The PCI-4451/4452/4453/4454 User Manual is one piece of the
documentation set for your DAQ system. You could have any of several
types of manuals depending on the hardware and software in your system.
Use the manuals you have as follows:
•
Software documentation—You may have both application software
and NI-DAQ software documentation. National Instruments
application software includes LabVIEW, LabWindows/CVI,
ComponentWorks, Measure, and VirtualBench. After you set up your
hardware system, use either your application software documentation
or the NI-DAQ documentation to help you write your application.
•
Accessory installation guides or manuals—If you are using accessory
products, read the terminal block and cable assembly installation
guides. They explain how to physically connect the relevant pieces
of the system. Consult these guides when you are making your
connections.
