Unfortunately, as the other two posts have referred to, most people on this forum don't have a lot of knowledge of Crestron or specific Crestron equipment.

You might want to look on a more 'generic' forum, like RemoteCentral, where more Crestron installers may hang out.  They don't hang out here.

Good luck with your project.
