I'm a bit miffed at elite right now. The literature appears to indicate that the 12v trigger is included as part of the basic system, however Elite says that there is a special "adapter" for the trigger function - at the low, low price of $40 (including shipping). Seems a bit steep for a $250 screen, if you ask me (and $15 of that is shipping...somebody needs to tell them they don't have to send it in a 10lb box).
Anyway - does anyone know what the pinout is on the RJ45? My screen location is wired with a bare cat5 on both ends anyway, so if I knew the 12v and ground pinouts I could hook it up...unless there's some current limiting or voltage modifying hardare involved in the adapter.
Edit - got my answer...maybe it will save somebody else $40. The CS rep at elite said that you could use a cat5 cable and just connect the orange and green wires as spec'd, but you can't. The proper pinout for a v1.4 screen is to use pin 7 as +12v and pin 8 as ground. For a standard cat5, that means the brown/white-brown pair is the proper pinout. Note that the ground, in combination with several other pins (no, I didn't write them down) has a voltage from 1.4 to 3.7, and shorting across the pins provided up, down, and trigger-like (up=closed, down=open) functions.
In Elite's defense, the $25 might not be out of bounds for a rarely used item that clearly was hand-crimped with a custom color order, then trimmed, heat-shrinked, and pre-cut for stripping, then boxed and and packed (in a HUGE shipping box). Still, with a simple diagram I could have crimped one up with my own tool for about $0.75 and been done a week ago.
