Matlab throw this error with U2300A/U2500A "??? Error using ==> daqhwinfo at 115
"??? Error using ==> daqhwinfo at 115
Failure to find requested data acquisition device: agilentu2500."
Please check whether your Matlab adaptor is installed at the following path:
C:\Program Files\Agilent\DAQMATLABAdaptor\U2300 Series\AgilentU2300.dll
C:\Program Files\Agilent\DAQMATLABAdaptor\U2500 Series\AgilentU2500.dll
If the *.dll files are not located in those directories, this may be because there is no Matlab Adaptor installed or you've installed an older version of Matlab Adaptor which resides typically at the path C:\Program Files\IVI\Drivers\AgU2300MATLAB\. If you've determined that you've installed the older version of Matlab Adaptor, please install the latest Matlab Adaptor from www.agilent.com.
If you're certain that you've installed the latest Matlab Adaptor and still sees the same error message, do take note that whenever you install a new Matlab, you have to re-register your Matlab Adaptor everytime after the Matlab installation.
To do the registration, simply type in
For U2300A :
daqregister('C:\Program Files\Agilent\DAQMATLABAdaptor\U2300 Series\AgilentU2300.dll')
For U2500A :
daqregister('C:\Program Files\Agilent\DAQMATLABAdaptor\U2500 Series\AgilentU2500.dll')
This is only a one time registration per each Matlab installation. You can start using Matlab to communicate with your instruments now.
