I am using a National Instruments PCI-6602 digital I/O board with NIDAQ version 6.9.1 and MATLAB 6.0 (R12) with the Data Acquisition Toolbox 2.0 (R12).
I receive the following errors:
   dio=digitalio('nidaq',1);
 ??? Error using ==> digitalio/digitalio

 NI-DAQ: The specified attribute is not relevant.

NI Digital IO boards were not supported with Data Acquisition Toolbox 2.0 (R12), but these are supported as of Data Acquisition Toolbox 2.1 (R12.1).
