About This Manual

The National Instruments Documentation Set

The SCXI-1162HV User Manual is one piece of the documentation set for your DAQ or SCXI

system. You could have any of several types of manuals, depending on the hardware and

software in your system. Use these different types of manuals 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 manuals–Examples of software manuals you may have are the LabVIEW and

LabWindows®manual sets and the NI-DAQ manuals. After you have set up your hardware

system, use either the application software (LabVIEW or LabWindows) manuals or the

NI-DAQ manuals to help you write your application. If you have a large and complicated

system, it is worthwhile to look through the software manuals 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 or accessory board user manuals. They

explain how to physically connect the relevant pieces of the system. Consult these guides

when you are making your connections.

• SCXI chassis manuals–If you are using SCXI, read these manuals for maintenance

information on the chassis and installation instructions.
