Note: After installing a VI package containing an instrument driver FPGA extensions host example, before opening any of the host VIs, move the sub-directories installed under the example parent directory into c:\Program Files\National Instruments\NI VST\Custom Bitfiles\ (32-bit Windows) or c:\Program Files (x86)\National Instruments\NI VST\Custom Bitfiles\ (64-bit Windows). The Custom Bitfiles directory may require manual creation, and this process requires administrative privileges. After moving these files, c:\Program Files[ (x86)]\National Instruments\NI VST\Custom Bitfiles\[Sub-directory Name]\Open FPGA Session.vi" should be a valid file path.

The NI PXIe-5644R and PXIe-5645R Vector Signal Transceivers each feature 24 digital lines that can be used for either digital output or input. This VI Package installs example code and the necessary dependencies that provide the user with software-timed control over these lines. Example code is installed to National Instruments\LabVIEW 2012\examples\NI Static Digital Host Example for the NI PXIe-5644R-45R .
