National Instruments Documentation

The AT-MIO/AI 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—Examples of software documentation

you may have are the LabVIEW and LabWindows/CVI

documentation sets and the NI-DAQ documentation. After you 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.

• 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
