We were hired to just do control. I wound never have specked this gear. Finally figured out the issue. Vanco tech support gave the wrong info to the installers. They have piss poor documentation. Everything was reversed. Now have RTI controlling it, and Crestron controlling RTI. Do yourselves a favor and stay away from it.
