Just found a video on PreSonus site that says you can mulitrack record over AVB ethernet.
Here is the YouTube video -
Go to 1:00 in the video where he talks about all the way of recording; SD stereo recording, USB multitrack, and Record via AVB.
I would assume AVB works similarly to how Dante protocol works, but I would recommend using StudioOne or the Capture software that comes with the unit, as it is more likely to be compatible with the unit.
