Querying number of channels on a device

[Ken_Brooks]

How can I ask programmatically, "Dev0, how many analog output channels do you support?"

[Mark_Yedinak]

It would depend on the device. I would look at the manual for the device you are using and see what what it's API is. As written no one can give you an answer since it all depends on what you are talking to.

I stand corrected. Will this work for all devices?

Forget to mention the path to this property node :

Functions palette >> Measurement I/O >> NI-DAQmx >> Advanced >> System Setup >> Device Node

or easier and faster (LV8.6 and later) : Ctrl+Space to show Quick Drop >> type Device Node >> select DAQmx Device Property Node

I expect it to work with all DAQmx devices but (obviously) I haven't tested it for all of them...
