GPIO In (NV-32-H)
The NV-32-H includes two General Purpose Input pins for extension of Q-SYS Control to third-party devices. In the Q-SYS Designer component properties, you can configure the input signal type for each pin – contact closure, digital, analog, potentiometer, or raw.
![Closed](../../Skins/Default/Stylesheets/Images/transparent.gif)
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.

Core Properties
Name
The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.
Note: This name must match the Hostname for the Core as defined in Core Manager. If you use Telnet or third-party external control, you must enter the Name exactly as it is entered here.
Location
User-defined name that groups the component with other components in the same physical location – for example, "Rack 1" – or in the same organizational scheme.+
Is Required
When enabled, and the device is not found on the network, the device is reported as 'Missing', which is an error condition. This is the default behavior. When disabled, and the device is not found on the network, the device is reported as 'Not Present', which is not an error condition. This option only appears when NV-32-H is set to Encoder or Decoder; it does not appear when set to Core Mode.
Dynamically Paired
Indicates that this virtual component can be paired with the same type of hardware without changing the network ID of the hardware or the name of this component. Refer to the Q-SYS Core Manager Dynamic Pairing topic for more information. The default is 'No'. This option only appears when NV-32-H is set to Encoder or Decoder; it does not appear when set to Core Mode.
Model
Select your Q-SYS Core processor model. See GPIO In (NV-32-H) for a list of selectable Core models. This option only shows when NV-32-H is set to Core Mode; it does not appear when set as Encoder or Decoder.
External USB Audio
When enabled, you can connect an external audio device to the USB input and route audio to and from that device. See External USB Audio Device In and External USB Audio Device Out.
Network Receive Buffer
Adds extra buffer time to the default maximum of 1 ms.
Additional Network Receive Buffer time is useful in (rare) cases where the network latency through the network exceeds the default maximum. Additional network latency my be introduced by sub-optimal QoS functionality, some layer-3 routing implementations, long distances or large networks.
Because the specified additional latency is added both to transfers from IO Frames to the Core and from the Core to IO Frames, the additional system latency is twice the amount of additional receive buffer selected. Total system latency based on this setting is calculated and displayed immediately below the Network Receive Buffer property.
This option only shows when NV-32-H is set to Core Mode; it does not appear when set as Encoder or Decoder.
HDMI / Shift AV
Device Type
Can set the NV-32-H as Core Mode, Decoder, or Encoder.
Note: When deploying a design to an NV-32-H (Core Mode) that changes the operational mode from either Core Mode to Encoder, Encoder to Core Mode, or Encoder to Decoder, or Decoder to Encoder, the device will automatically be rebooted.

HDMI Output Mode
This property determines the functionality of the NV-32-H HDMI outputs.
- HDMI 1: (Default) Video and audio output is enabled for the HDMI 1 output connector.
- HDMI 1 + HDMI 2: Video and audio output is enabled for both the HDMI 1 and HDMI 2 output connectors. Each output can be assigned an independent source.
Note: When HDMI 1 + HDMI 2 mode is selected, source EDID files are forced to a maximum resolution of 1080p60.
HDMI 1 Audio Pins
If enabled in the component Properties (HDMI Output Mode is set to "HDMI 1 + HDMI 2"), select the number of audio pins to expose – from 0 to 8 – for routing to other Q-SYS audio components, such as a network amplifier. This audio corresponds to the HDMI Output 1 or 2 source you select in the HDMI I/O control panel.
Tip: These pins automatically send audio for whatever HDMI video source is selected for display. No additional programming is required to align audio and video signals.
Source Index
Select how control indexes are determined for each NV-32-H streaming component in your design, including HDMI I/O (NV-32-H), Status (NV-32-H), and System Link. This affects how controls are referenced in scripting components, including Named Controls in Block Controller and Text Controller.
- Auto: (Default) Components in existing designs upgraded to Q-SYS v9.2.0 and later will continue to use a 0-based index. New components use a 1-based index, which matches the functionality of other Q-SYS components.
- 0-Based: The component will use a 0-based index, meaning that control indexing starts at 0. This is useful for maintaining consistency with other components and for re-using control scripts.
- 1-Based: The component will use a 1-based index, meaning that control indexing starts at 1. This matches the functionality of other Q-SYS components.
![Closed](../../Skins/Default/Stylesheets/Images/transparent.gif)
For a control called "Select AV 1" in the control panel:
- 0-Based: The control would have an index value of 0. As in, hdmi.out.0.select.avh.0.

USB Bridging
These properties appear based on the USB bridging capabilities of the Q-SYS device. Refer to the USB Video Bridge and USB Audio Bridge topics to see what Q-SYS Core processors and peripherals support USB bridging.
USB Bridge Name
User-defined name given to the USB Bridge, from 1 to 24 characters. The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted. This option only appears when the NV-32-H is set to Core Mode; it does not appear when set as an Encoder or Decoder.
Zoom Compatibility
If you are using the HID Conferencing component to control a remote computer running Zoom, set this property to 'Enabled.' Otherwise, when controlling another conferencing app such as Skype for Business, set to 'Disabled' (default). When this property is enabled, the USB Bridge Name property is disabled, and the USB Bridge automatically uses the name of the device for compatibility with Zoom's allowed device list – for example, "Q-SYS Core 110f" or "Q-SYS NV-32-H".
Tip: Enabling Zoom Compatibility may improve the user experience with macOS conferencing solutions.
USB Video Bridge
Enable the USB Video Bridge to bridge Q-SYS Mediacast streams to USB, enabling you to view Mediacast video on a connected computer. This exposes the USB Video Bridge component in the I/O-USB Bridge Inventory tree. To see what Properties are available when the USB Video Bridge is enabled, see USB Video Bridge.
UVC Camera Control
When this is enabled (disabled by default), the camera can be controlled by far-end third party applications which support Relative Movement Commands. When disabled, the cameras cannot be controlled by the applications.
Video Formats
See Video Formats for more information.
USB Audio Bridge
Provides the capability of passing audio via USB. When this is set to anything except 'Disabled', you can drag the Speakerphone and/or Sound Card components from the device's Inventory tree into your design. To see what Properties are available when the USB Audio Bridge is enabled, see USB Audio Bridge.
- Disabled: (Default)

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:
- Turn the physical potentiometer to its minimum position.
- Click the Calibrate Min button. A value displays in the Min Position field.
- Turn the physical potentiometer to its maximum position.
- 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.
