Setting up a Motion Sensor on XT2145

Hi!

I've browsed through previous topics but was still unable to get this to work.

I want to set up my player so that:

1) It plays a video (video1) on loop.
2) A motion sensor detects a person nearby and another video (video2) starts to play.
3) Video2 plays until the end and then switches to video1 that starts to loop until the motion sensor is triggered again.

Now, parts 1 and 3 are easy to produce, but I just cannot get the second part working.

I've got a PIR-8 Motion sensor with an output and an input of 12/24V. I've set up the bright sign player so that GPIO ports 0 and 1 should accept an input signal (the rest I just configured as output ports) from the motion sensor's output signal.

When I wave my hand in front of the sensor, nothing happens. However, if I unplug the cable from the sensor and insert it back in, the Brightsign detects the electric current and changes from video1 to video2. To me this seems to indicate that the Brightsign player detects the motion sensor and when it's plugged in, it gets the signal of a button being pressed down. However, for some reason, it only works when the motion sensor is unplugged and plugged in again.

I am completely new to Brightsign players and the use of GPIO ports and thats why any help is appreciated.

I will add a few pics and screenshots for more detailed info:

Here's the wiring on the motion sensor.

 

And here's the wiring on the Brightsign player.


Here's the Playlist setup with all the signals I've set up.

And finally the way I've set up the GPIO inputs and outputs.

One thing that game to my mind is: do i need to send an output signal from the Brightsign player to the motion sensor for this to work? And if I do, how would I do that?

Any other ideas or thoughts?

    It sounds like the PIR-8 sensor isn’t delivering a clean digital signal the BrightSign GPIO can detect reliably. Try using a relay or transistor circuit to convert the 12/24V output to a proper 3.3V or 5V GPIO pulse. Also confirm your GPIO input is set to “active low” or “active high” depending on your wiring. That should fix the trigger issue. myAARPMedicare

    It seems like the PIR-8 sensor isn't providing a clean digital signal that the BrightSign GPIO can reliably detect. Try using a relay or transistor circuit to convert the 12V or 24V output to a stable 3.3V or 5V GPIO pulse. Additionally, make sure your GPIO input is configured for the correct mode—either "active low" or "active high"—based on your wiring setup. This should resolve the trigger issue. myaarpmedicare

    I ran into something similar with a BrightSign player—it turned out the GPIO was expecting a clean low/high trigger, while my PIR sensor was holding the line high instead of pulsing it, so it only reacted on reconnect. You might need a relay or proper voltage/interface setup so the signal behaves like a momentary trigger. It’s a bit like fnf  —you need the timing and input signals just right, or the system won’t respond the way you expect.
