A problem about DAQ assistant and 6259

[过客wasd]

I want to use DAQ assistant to control the USB-6259 to generate signals

But there are no output in any channels

However, if i use DAQmx VIs programmed in labview, i can generate signals.

Can you help me with this？

Hi wasd,

why do you want to use the DAQAssistent when you are familiar with "plain" DAQmx functions?

Recommandation: use the simple DAQmx functions. They are easy to use, simple to implement and will support you better when your DAQmx tasks become more complicated!

Please read and apply the article that GerdW referenced.  I've discussed "The Dreaded DAQ Assistant and its Evil Twin, the Dynamic Data Wire" with some of my students, who usually get the point and develop VIs that they (and I) can understand and (more to the point) accomplish what they want.
