National Instruments Documentation

The

DAQCard E Series 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:

•

Getting Started with SCXI

—If you are using SCXI, this is the first

manual you should read. It gives an overview of the SCXI system

and contains the most commonly needed information for the

modules, chassis, and software.

• Your SCXI hardware user manuals—If you are using SCXI, read

these manuals next for detailed information about signal

connections and module configuration. They also explain in greater

detail how the module works and contain application hints.

• Your DAQ hardware user manuals—These manuals have detailed

information about the DAQ hardware that plugs into or is

connected to your computer. Use these manuals for hardware

installation and configuration instructions, specification

information about your DAQ hardware, and application hints.

• Software documentation—You might have several sets of software

documentation, including LabVIEW, LabWindows



/CVI, and

NI-DAQ. After you have set up your hardware system, use either

the application software (LabVIEW or LabWindows/CVI) or the

NI-DAQ documentation to help you write your application. If you

have a large and complicated system, it is worthwhile to look

through the software documentation before you configure your

hardware.
