Euroscreen® AutoLink Trigger -ER is a RF (radio) based trigger that is connected to the projectors mains power cable.
The Autolink detects when the projector switches on and starts to draw current. It then sends a wireless RF-signal to the control box that is connected to the projector screen. (2327473 -ER Control Box)
The same happens when the projector is shut of and stops to draw current.
This results in that the projector screen goes down/up when the projector is tured on/off automatically, without any need for a separate remote control or any other manual input.
-A very elegant, easy and wireless control solution!
