HDX with Dante Via

[freakhouse]

I've got a HD I/O and HDX card on Mac Pro. I've also got a Presonus Mixer RM16AI with a Dante card in it in a room about 50 feet away. Ethernet cable is running from Dante to the Mac. My goal is to use the Presonus to mic drums and bring up those inputs in Pro Tools. I want to monitor in the control room and have the drummer be able to monitor from the Presonus outputs. So far, I've been able to get the inputs to come up in Pro Tools and get audio but despite many experiments have yet to be able to get my main stereo bus to come up on the HD I/O. Seemingly I've connected the right elements to each other in Via, but obviously there is some piece of the puzzle I'm missing.
