6 Zone Monoprice home automation

I searched but couldnt find here or on monoprice's site.  I wanted to see if anyone had any pictures of the back of the keypads?  I wanted to see if there were 2 RJ45 connectors so I could add a volume control to another room on the same zone?
 
Thanks!

Did you check/ask in this thread? http://cocoontech.com/forums/topic/25893-monoprice-multi-zone-audio/
 
I'd guess that's probably the best place on this forum.
