Software

Calibrating the NI 9230/9232 requires the installation of NI-DAQmx on the calibration system. 
Table 1 shows the necessary versions for each connector variation. 

You can download NI-DAQmx from 

ni.com/downloads

. NI-DAQmx supports LabVIEW, 

LabWindows

/CVI

, C/C++, C#, and Visual Basic .NET. When you install NI-DAQmx you 

only need to install support for the application software that you intend to use.
