Hi,
I am using the NI USB-4431. I would like to generate a signal and make a data acquisition but during the task "daqmx write" it appears an error (error code 200077).
I also have the NI PXIe-1082 with the acquisition card NI PXI-4461 and it works correctly... so I do not understand why the same code works with this card and not with the USB-4431 (I have naturaly changed the physical channel...)
You can see the printscreen and the code in attachment
Thank you
Cedric
