Matlab can't find NI PCI 6723 Analog Output Card

Dear All, I am having a problem with a analog output card PCI 6723 on Matlab R2009a. After installing NI-DAQmx (9.0.x) drivers and typing

daqhwinfo('nidaq')

I get

??? {Error using ==> daqhwinfo at 115
No nidaq adaptors are installed.

Please Help

Hi Michal,

Are you on a Windows Vista or a Windows 7 machine? If that's the case then you might need to start MATLAB with admin priv to allow MATLAB to access these drivers.

Just right click on the Matlab short cut and choose start/Run in Admin mode and try the daqhwinfo nidaq

command

Thanks a lot, it was very helpful. Everything work just fine.

Hi Michal

This is sangwoo from Texas. I have a question.

Did you register the driver into Matlab before you run??

This is because I have difficulty registering Daq adaptor for matlab.

Hi Sangwoo,

I installed NI-DAQmx 9.0.x and I checked if the card works under MAX. I did not register any drivers in Matlab. Is the card visible in MAX or Hardware Manager? If it is, Matlab should see it. Try to run Matlab in Admin mode.
