Does the Data Acquisition Toolbox 2.12 (R2007a) support the SCXI-1112 and SCXI -1122 devices from National Instruments?

I would like to use National Instruments boards SCXI-1112 and SCXI-1122 with Data Acquisition Toolbox.

This enhancement has been incorporated in Release 2008b (R2008b). For previous product releases, read below for any possible workarounds:

The Data Acquisition Toolbox software does not support National Instruments SCXI-1112 and SCXI-1122.

From version 2.10 (R2007a) onwards of the Data Acquisition Toolbox software, you can manually add support for these devices as follows:

1. Exit the MATLAB environment.

2. Find the following file:

$MATLABROOT\toolbox\daq\daq\private\mwnidaqmx.ini

where $MATLABROOT 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:

 [SCXI-1112]

 hasAnalogInput = true

 numAIChannels = 8

 inputRangeTestVoltage = 0.0050

 hasAnalogOutput = false

 hasDigitalIO = false

 [SCXI-1122]

 hasAnalogInput = true

 numAIChannels = 16

 hasAnalogOutput = false

 hasDigitalIO = false

5. Save the file mwnidaqmx.ini and restart MATLAB.

You cannot work around this issue if you are using versions earlier than 2.10 (R2007a) of the Data Acquisition Toolbox.
