Solved!

I have not needed to load any drivers other than VISA when communicating with the instrument via SCPI.

Right...

 

I was just having difficulty with the most basic SCPI commands like *IDN?\n in NI MAX even when I verified the VISA session to the device.

 

My solution was to get .NET 3.5 turned on and made sure I had IVI configured correctly as the DAQ970 drivers I pointed to are indeed IVI.

The DAQ970A driver on the NI site has a bug with the measurement setup VIs.

Specifically, the voltage configuration commands are wrong - The DAQ970A doesn't support all the options that the VI sends. See page 106 of the DAQ970 programming guide. The attached VI fixes these issues.
