NIDisk User Guide
The NIDisk User Guide (this document) is installed as a PDF (Portable Document Format)
file in the \docs directory under the SIGNAL root directory (normally c:\Program
Files\Engineering Design\Signal 4.0). PDF files require the Acrobat Reader program from
Adobe Corporation for viewing. If not already installed, this program is available for free
download at
http://www.adobe.com/products/acrobat/readstep.html. Acrobat Reader is also
required by Help | User Guide on the NIDisk menu.
Acrobat Reader provides full text search capability, which can be used like an index, to find
occurrences of a particular word or phrase in the document. To perform a text search, select
Edit | Find in the Acrobat menu.
This guide can be accessed from the NIDisk menu at Help | User Guide.
3. Getting Started
Connecting Signals to the I/O board
See Appendix D, "I/O Hardware Connections" in the SIGNAL Reference Guide for
important notes on connecting signals to the I/O board.
NOTE: if you are running the version of NIDisk which supports high-resolution output
synchronization, you must make certain digital connections in order to perform analog
I/O. See "Triggering an External System from NIDisk" below for details.
NOTE: this capability is not supported in NIDisk 3.0.
