Okay, to begin I will list the equipment that I have questions about the setup:

Epson 5010e Home Cinema Projector
Visual Apex 106" Tensioned electric screen
Onkyo 818 AVR

I am just setting up everything now - only the screen and projector are installed and I am planning on finishing wiring/installing the speakers this weekend along with installing AVR.

Before we start, I want to mention that the visual apex screen came with a wireless 12v trigger. In theory, the 12v trigger is plugged into the trigger port on the Epson (it has one) and when the screen is powered on, the screen drops / powered off, screen raises. I have not installed this because I am trying to figure out another piece of this puzzle. How do I program the Onkyo 818 to power on the projector when a certain activity is selected? I will be using a Harmony 1100 remote (needs to be programmed still).

Basically, the screen is mounted above my TV and when I choose to "Watch Theater" activity (or whatever I end up calling it), the AVR will change HDMI outputs, the correct devices will be powered on/off and the correct inputs selected. But because the Projector is not in my AV closet, how does the AVR tell the projector to turn on? The Onkyo appears to have 2 12v trigger outs (labelled zone 2 and zone 3).

Thoughts? Thanks!

The Epson can't be controlled from the Onkyo. You'll have to use the Harmony. The 12V trigger out on epson would lower the screen when the projector is turned on and the screen wil go up when the projector is powered off. You could connect the screen to the Onkyo but the 12V triggers on receivers are more commony used to turn on amplifiers when the receiver powers on. The Epson does not have a 12V trigger input so it can't be controlled by a 12V trigger device, it can only trigger other devices.
