How can I use the National Instruments PCI- and PXI-623x series devices with the Data Acquisition Toolbox 2.8.1 (R2006a)?

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

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:
