Plug and Play Instrument Driver Installation Instructions

Most Plug and Play instrument drivers are compressed with a .zip extension. Files with a .zip extension are compressed archive files for Windows, Linux, Sun, HP-UX, and Macintosh users. These files can be unzipped into appropriate directory on a system using WinZip. WinZip makes it easy for users to work with archives. For more information about WinZip, please visit the WinZip Web site. UNIX users should download the Windows version and then use the UNIX unzip utility to extract the files.

LabVIEW

In general, the LabVIEW Plug and Play instrument driver will consist of one or two VI library files and one or more menu files (*.mnu). These should all be saved in a unique directory within your <LabVIEW>\instr.lib directory. For example, the HP34401A instrument driver files and their relative directory structure is shown below:

<LabVIEW>\instr.lib\hp34401a\

  • actstat.mnu
  • applic.mnu
  • config.mnu
  • data.mnu
  • dir.mnu
  • hp34401a.llb
  • hp34401au.llb
  • util.mnu

Note: Most instrument driver .zip files already contain relative path information. The .zip file should be extracted directly to the <LabVIEW>\instr.lib directory.

LabVIEW Plug and Play (project-style)

Although the LabVIEW Plug and Play (project-style) instrument drivers have a different file structure than LabVIEW Plug and Play instrument drivers, the project-style driver also needs to be saved in a unique directory within your <LabVIEW>\instr.lib directory. For example, the Agilent 34401 project-style instrument driver files and their relative directory structure is shown below:

<LabVIEW>\instr.lib\Agilent 34401\

  • Examples
  • Private
  • Public
  • Agilent 34401 Readme.html
  • Agilent 34401.lvlib
  • Agilent 34401.lvproj

Note: Most instrument driver .zip files already contain relative path information. The .zip file should be extracted directly to the <LabVIEW>\instr.lib directory.

LabWindows/CVI

LabWindows/CVI users can unzip the files into any directory, although the cvi/instr directory provides a convenient location for all your instrument driver files.

Required Software

Many of the instrument drivers require NI-VISA to be installed. You can download the latest version of VISA. In addition to VISA, the appropriate device driver(s) (NI-488.2, NI-VXI, etc) also need to be installed along with the appropriate hardware. The latest versions of these drivers can be found at the NI Hardware Drivers page.
