Not seeing all my channels for the USB-6009

[2B]

I am writing a VI to communicate to my USB-6009. I what to use the counter option which is channel PFIO. When I wrote the VI, I used the physical channel VI to select the channel that I need to accomplish this. But it only lets me select ai0-ai7. How do I get it to see the PFIO channel and all the other channels that the USB-6009 has to offer?

When you use the DAQmx Create Channel, you have to select the polymorphic type. That's the little box below the function. Click on the arrow and change the type to Counter Input>Count Edges. Then the physical channel control/constant you create will list Dev1/Ctr1. You might have to right click on the physical channel control/constant and select I/O Name Filtering to change if from the analog input type you had originally created.
