Q: Can I Interface my 5-12V Trigger with an AC Power Switch?

There’s a couple of suggestions.

1. If controlling your screen’s drop and rise with a light switch, we offer our (ZIW) integrated wall switch that will work just fine with your electric projection screen.
2. To operate the projection screen using the 12-Volt trigger,  We recommend connecting the trigger’s RJ45 connection to your projector since it was designed solely for that purpose. Running the 12-Volt trigger through an AC/DC converter will likely not work and may even prove harmful to your product or the projector screen’s main board, so we strongly advise against experimentation with mismatched accessories doing what they were not designed to do.
