How To | Latching the Virtual Page Station Talk button from the control pin via GPIO
Learn how to control a Virtual Page Station Talk button from a control pin using GPIO.
Procedure
Some system design specifications may require GPIO to trigger a Virtual Page Station Talk button with the desired function to latch after a button press. Because the VPS component Talk button control pin is unable to latch like the button within the component, some additional configuration is required in Q-SYS Designer.
Use the steps below to latch the Virtual Page Station talk button from a control pin:
- Add a Flip-Flop component and expose the Toggle and State control pins .
- Add Virtual Page Station component and expose the Talk control pin.
- Connect the desired GPIO input to the Flip-Flop Toggle input pin.
- Connect the Flip-Flop Toggle output pin to the Talk pin of the VPS.
- Connect the VPS control to the PA Router as normal.
Note
This setup is only required if the GPIO input device is a momentary trigger. A latching/toggle switch will not require the Flip-Flop.
