Software

Install NI-DAQmx 9.3 or later on the calibration computer. NI-DAQmx includes high-level function 
calls to simplify the task of writing software to calibrate modules. You must have the proper module 
driver installed on the calibration system before calibrating the module.

Note

NI recommends that you install the NI-DAQmx driver software before physically installing 

the NI PXIe-4353. NI-DAQmx, available at 

ni.com/downloads

, configures and controls the 

NI PXIe-4353.

NI-DAQmx supports a number of programming languages, including LabVIEW, LabWindows

/CVI

C/C++, C#, and Visual Basic .NET.

You can access the NI-DAQmx header file, 

NIDAQmx.h

, like any standard library. You can find 

examples of how to use the NI-DAQmx driver by entering the Info Code 

NIDAQmxExLoc

 at 

ni.com/info

 there you will find the topic
