The PXIe-2461 User Manual, publication no. 981038, states that there is a LabWindows/CVI API (Getting Started page 2-4) but I am unable to find any C drivers on National Instruments or Astronics' websites. The link provided in the User Manual is to a LabVIEW driver. Astronics was contacted but they were not able to provide a C driver. Does anyone have a C driver for the PXIe-2461 for a Windows system?
