GPIO In (QIO-GP8x8, QIO-FLEX4A)

Some Q-SYS QIO devices have General Purpose Input pins for extension of Q-SYS Control to third-party devices. In the Q-SYS Designer Software component properties, you can configure the input signal type for each pin – digital, contact closure, potentiometer, analog, or raw.

To see GPIO interface information, Example Applications, and Behavior During Boot-up and Redeploy for your device, visit General Purpose Input Output (GPIO) Application.

Tip: For additional properties not listed, refer to the Properties Panel help topic for more information.

GPIO-1 to 8 or 4 (depending on device)

Type

Select the type of GPIO input:

  • Digital Input (TTL 3.3V)
  • Contact Closure Input
  • Potentiometer (10k Ohm, 12V)
  • Potentiometer (2-wire)
  • Analog Input (0-24V, low z)
  • Raw

Digital Input

This LED illuminates when there is a digital input present on a GPIO pin. Supported Types:

  • Digital Input (+3.3VDC)
  • Contact Closure – When this Type is selected, the pin has approximately 9 to 10VDC present when the contact is open (or nothing is connected) and the LED is off. When the contact is closed (pin is shorted to ground), the LED is on.
  • Raw

Analog Input

The analog input knob appears for these Types:

  • Analog – allows a low impedance, 0 – 24VDC signal input
  • Raw

Both input voltages are displayed on a read-only knob control.

Potentiometer: Min Position, Calibrate Min, Max Position, Calibrate Max

The Potentiometer knob follows the position of the physical potentiometer connected to the GPIO pin. To calibrate Q-SYS to the potentiometer:

  1. Turn the physical potentiometer to its minimum position.
  2. Click the Calibrate Min button. A value displays in the Min Position field.
  3. Turn the physical potentiometer to its maximum position.
  4. Click the Calibrate Max button. A value displays in the Max Position field.

If you know the values for Min Position or Max Position, you can enter them manually.

Pullup Enable

When enabled, provides a 5.11K pull-up resistor to +12VDC on the input pin when the Type is Raw.
