Manufacturer Overview
This radio RFR box and STR will give you the ability to lower and retract every time you power up or shut down your projector. You just need to wire the RFR box to your projector screen that has 4 core cable.
It also comes with an up and down switch located on the side of the box and is RS232 and Contact closure capable which covers most control options.
How does this work?
You plug the STR “kettle” lead into the projector and then plug the projector “kettle” lead into the STR, so the STR sits in-between the projector and the projectors power lead.
The then senses when the projector is turned on or off, and sends a wireless signal to the RFR box which has been wired to your projection screen. Which in turn triggers the screen to lower and retract. The means you can control your screen and projector using only your projector remote control.
