IOtech LabVIEW Substitution VIs

Foreword

IOtech LabVIEW Substitution VIs can be used to replace NI-DAQTM VIs. The Substitution VIs provide a
means of using IOtech DaqBoard/2000 Series boards with LabVIEW programs, while maintaining the
NI-DAQ look and feel.

Note that this document serves as a supplement to both DaqBoard/2000 Series and LabVIEW
documentation.

This document is intended for use by individuals who:

• Want to convert LabVIEW VIs so they may be used with IOtech Daqboard/2000 Series

boards.

• Are familiar with LabVIEW VIs and would like to create new VIs for use with IOtech

Daqboard/2000 Series boards.

IOtech LabVIEW Substitution VIs do not support DBK signal conditioning options.

IOtech LabVIEW Substitution VIs are compatible with LabVIEW versions 5.1 and higher. There are no
special system requirements for using the substitution VIs, other than those specified for the version of
LabVIEW used.

LabVIEW support is provided for basic Analog Input, Analog Output, Digital IO, and Counter Functions.
Each includes program examples that can be modified, or used as is.
