IOtech LabVIEW Substitution VIs 10-03-02 3-1
Using IOtech LabVIEW Substitution VIs 3
Overview
The IOtech Data Acquisition sub-directory contains folders for the various types of Virtual Instruments.
Each folder contains pertinent sample programs. The folders are designated:
• Analog Input
• Analog Output
• Counter
• Digital IO
In addition to these four VI folders, the sub-directory also contains a Documentation folder. The folders
can be accessed from the Windows Start Menu, under the LabVIEW directory (located under
DaqXSoftware).
IOtech LabVIEW Substitution VIs were designed to emulate National Instruments VIs. The substitutions
can be made in applications where an IOtech DaqBoard/2000 Series board is being used to replace a
NI-DAQ “E” Series device, a PC-LPM-16, or an AT-MIO-16 “H” or “L” Series board; however, for the
AT-MIO-16 L, the x500 gain-setting will not be supported. NI devices can typically be replaced with little
effort. An example follows shortly.
