We are using handsets with a BrightSign HD1010 that have a magnetically activated reed switch. When the handset is hung up the switch is closed.
The BrightSign is controlled by a touch screen to select specific video to play. We want the video to stop when the handset is hung up. How do we set the BrightSign to respond to a contact OPEN rather than contact CLOSE?
Can this feature be added to the Presentation Properties with a check box to select NO/NC inputs (and outputs). We frequently use standard security system IR sensors for interactive applications and they usually have normally closed contacts. We can work around the problem with a relay but its a bit clunky!
