A problem testing input channels on 6527 card, they won't turn on via studio

[darmoux]

Hi.
I have installed the card correctly (it passes the test) and wrote an application catching events in case of output/input changes.
I wanted to test the application via the measurment studio, but I can not turn the input channels on, i.e. nothing happens when I press the "Make input button". The output channels testing works great.
Thanks 4 your time.

Hello;

You can do two tests at this point to make sure the digital lines are working properly. The first one is to run Test Panel in MAX, go to the digital tab, configure the same digital line you are having problems on Measurement Studio, and see if that works fine in MAX. If it doesn't the board is probably defected.

If that works out fine, you can now run one of the shipping examples that shows how to do digital lines, for Measurement Studio. You can find those examples at C:\Program Files\National Instruments\NI-DAQ\examples\Visual Basic. If that works out fine too, the problem is most likely on your Software.

Hope this helps.

Hi Filipe,thank you for your prompt response.
The channels do not work in MAX, however before I send the board back as defected, I would like to find out whether the problem is one of definition. The 6527 card has dedicated input and output channels. I am not supposed to be able to change the status of the input channel via standart API, but only through hardware, and maybe the problem is that MAX uses this API.
Please tell me if so and instruct me what to do.

Once again, thanks for your time
