DAQmx AI.Coupling property

[BowenM]

So, I've spent the last hour trying to find why I can't programmatically set the AI coupling property on my channels.  For me, the option just isn't listed.  No searching has pointed me in the right direction yet.

I'm sure I'm missing something simple, but I can't seem to figure out what.  Any suggestions?

I use the following DAQmx Channel node set the coupling, bias, etc, for my channels. I set it dynamically before the task starts.

EDIT: misread your question. Are you sure your device supports it? There is also a way to show all options when browsing.

Right click the top of the property node and select filter, Show All Attributes.

Kudos for that!  I never knew about that filter!   (Similarly, there's one for DAQmx terminal nodes that often requires right-clicking in order to "show advanced terminals".)

mcduff,

Thanks for the reply!  It was that filter... didn't even know it existed 🙂

And yes, the hardware supports it.  I just didn't have the hardware configured on my development PC - just the deploy, so that filter masked the option to change coupling.
