MATLAB: How to use the National Instruments PCI- and PXI-623x series devices with the Data Acquisition Toolbox 2.8.1 (R2006a)

Data Acquisition Toolbox

I would like to use the following NI PCI- and PXI-623x series devices with the Data Acquisition Toolbox 2.8.1(R2006a):
PCI-6230
PXI-6230
PCI-6232
PXI-6232
PCI-6233
PXI-6233

Best Answer

This enhancement has been incorporated in Release 2007a (R2007a). For previous product releases, read below for any possible workarounds:
The National Instruments PCI-623x series devices are not supported by the Data Acquisition Toolbox 2.8.1 (R2006a).
To work around this issue, perform these steps to add support for these devices:
1. Quit MATLAB.
2. Find the following file:
 $MATLAB\toolbox\daq\daq\private\mwnidaqmx.ini
where $MATLAB is the MATLAB root installation directory obtained by issuing:
matlabroot
at the MATLAB Command Prompt.
3. Make a copy of this file and rename it to mwnidaqmx.ini.old.
4. Open the file mwnidaqmx.ini in a text editor, and add the following lines at the end of the file:
