This manual describes the electrical and mechanical aspects of the
PCI-4451/4452/4453/4454 (PCI-445X) devices and contains information
concerning their operation. Unless otherwise noted, the text applies to all
devices.
The PCI-445X are high-performance, high-accuracy analog input devices
for the PCI bus, and all support external trigger functions. In addition, the
PCI-4451 and PCI-4453 are analog output devices, and the PCI-4451 and
PCI-4452 devices support digital I/O (DIO) and counter/timer functions.
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.
The following conventions are used in this manual:
Angle brackets containing numbers separated by an ellipsis represent a
range of values associated with a bit or signal name—for example,
+ACH<0..3>.
The ♦ symbol indicates that the text following it applies only to a specific
product, a specific operating system, or a specific software version.
