This enhancement has been incorporated in Release 2007b (R2007b). For previous product releases, read below for any possible workarounds:
The National Instruments PCI-6255 and PXI-6255 M series devices are not supported by 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 :
 $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:
 [PCI-6255] 
 hasAnalogInput   = true 
 numAIChannels    = 80 
 hasAnalogOutput  = true 
 numAOChannels    = 2 
 maxAOSampleRate  = 2860000,2000000 
 hasDigitalIO     = true 
 digitalPortSize  = 8,8,8 
 digitalPortCap   = 4,4,4 
 [PXI-6255] 
 hasAnalogInput   = true 
 numAIChannels    = 80 
 hasAnalogOutput  = true 
 numAOChannels    = 2 
 maxAOSampleRate  = 2860000,2000000 
 hasDigitalIO     = true 
 digitalPortSize  = 8,8,8 
 digitalPortCap   = 4,4,4
5. Save the file mwnidaqmx.ini and restart MATLAB.
