GPIO In (NV-32-H)

The GPIO In component represents the GPIO IN connection pins on the rear of the NV-32-H. Use one of the included 5-pin Euro connectors.

Note: The RS-232 and GPIO IN pins share a 5-pin Euro connector. You can use both connection types simultaneously.

1, 2

Two inputs, 0-24 V analog input or contact closure. Pins 1-2 are the equivalent of pins 1-2 in the Q-SYS Designer GPIO In component.

Ground

Earth ground reference for GPIO input and RS-232 connections.

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

GPIO-1, 2 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.
