Conventions

The following conventions are used in this guide:

<>

Angle brackets that contain numbers separated by an ellipsis represent 
a range of values associated with a bit or signal name—for example, 
AI <0..7>.

»

The 

»

 symbol leads you through nested menu items and dialog box options 

to a final action. The sequence 

File»Page Setup»Options

 directs you to

This icon denotes a note, which alerts you to important information.

This icon denotes a caution, which advises you of precautions to take to 
avoid injury, data loss, or a system crash.

 

When this symbol is marked on 

the product, refer to the 

Read Me First: Safety and Radio-Frequency 

Interference

 document, shipped with the product, for precautions to take.

When symbol is marked on a product, it denotes a warning advising you to 
take precautions to avoid electrical shock.

When symbol is marked on a product, it denotes a component that may be 
hot. Touching this component may result in bodily injury.

bold

Bold text denotes items that you must select in the software, such as menu 
items and dialog box options. Bold text also denotes parameter names.

italic

Italic text denotes variables, emphasis, a cross-reference, or an introduction 
to a key concept. Italic text also denotes text that is a placeholder for a word 
or value that you must supply.

monospace

Text in this font denotes text or characters that you should enter from the 
keyboard, sections of code, programming examples, and syntax examples. 
This font is also used for the proper names of disk drives, paths, directories, 
programs, subprograms, subroutines, device names, functions, operations, 
variables, filenames, and extensions.

SC-2345

SC-2345 refers to both the SC-2345 connector block and the SC-2345 
configurable connector.

SCC

SCC refers to any SCC series signal conditioning module.

SCC-AI

SCC-AI refers to any isolated analog input module in the SCC-AI Series 
unless otherwise noted.
