Kat Walk Mini Treadmill, Anyone got it to work?

I am a noob, but I’m hoping to learn. I have a Kat Walk Mini treadmill that I want to use with a VR Architectural model walk through. I got the SDK from KatVR and tried a very basic demo and I can’t get the treadmill to operate the Motion Controller Pawn in the simulation play. Has anyone had any success?

So it seems that you have to buy a dongle to use with the sdk to produce a game that natively supports the treadmill. This seems a little strange as the sdk doesn’t throw up any errors when I package the software using their template but it has been ordered and we shall see what happens.
