Overview

This chapter details the particular commands used to program Daq device applications. The first section of this

chapter describes briefly the layout of the API Command entries, and is followed by two useful reference

sections—first, a table describing the naming conventions of the predefined parameter values, and second, a

section breifly describing the use of mask and flag values. After this, two tables of contents are offered: an

alphabetical listing of the API commands, and a listing of API commands grouped into catagories of similar

function. The API command entries begin after the table of contents, and are themselves arranged in

alphabetical order. Following the commands, the API Error Code table is included, detailing the meaning of

possible error return messages.

Note: The term “DaqBoard/2000 Series” refers to both the PCI and compact PCI (cPCI) versions of the boards, unless

otherwise stated. For example: The use of “DaqBoard/2001” refers to both the DaqBoard/2001 and to the

cPCI DaqBoard/2001c.
