Serial Port (NV-32-H)
The NV-32-H includes an RS-232 connection for extension of Q-SYS Control to third-party devices, such as projectors, TVs, and A/V receivers. You can control and read from these devices using Lua script from a Q-SYS scripting component.
Tip: To learn about scripting in Q-SYS, see Control Scripting.
The Serial Port component represents the RS-232 serial connection pins on the rear of the NV-32-H.
Note: On the NV-32-H, the RS-232 and GPIO IN pins share a 5-pin Euro connector. You can use both connection types simultaneously.
Pin | Description |
---|---|
TX |
Transmit pin. Connect this pin to the RX (receive) pin on the other device. |
RX |
Receive pin. Connect this pin to the TX (transmit) pin on the other device. |
Ground |
Earth ground reference for GPIO input and RS-232 connections. |
The Serial Port component represents the RS 232 connector on the rear of the NV-32-H.
Input Pins
This component has no input pins.
Output Pins
Serial Port
Connect this pin to the Serial Input pin of a Q-SYS scripting component, such as Block Controller, Text Controller, or Control Script. You must configure these components for serial communication.
Core Properties
See the HDMI I/O (NV-32-H) topic for a list of available Network Video Endpoint Properties.
USB Bridging – Common Properties
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.
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.
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)
- Speakerphone (1 x 1): Provides a speakerphone with an input and output component, each having 1 audio connection.
- Sound Card (2 x 2): Provides a sound card with an input and output component, each having two (stereo) audio connections.
- Speakerphone and Sound Card: Provides one speakerphone and one sound card with the same capabilities as described above.
- Advanced – If supported, allows up to any combination of four speakerphone / sound cards.
Speakerphone Mode
This selection is available only when Speakerphone or Speakerphone and Sound Card is selected in the USB Audio Bridge property. Indicates if the Q-SYS design has Echo Canceling (EC) or Non-Echo Canceling (NEC). This information is provided to the PC or Mac operating system so it can determine whether or not to use its own echo canceling.
Graphic Properties
Label
Use the Label property to change the name of the component in the schematic. The Label property defaults to the component name. To learn more about renaming schematic elements, see Organizing Your Design.
Position
The coordinates reference a specific place in the schematic - for example,"100,100" (horizontal, vertical). 0,0 is the upper left corner of the schematic.
Fill
Sets the fill color of the component in the schematic.
Script Access Properties
Code Name
Displays the currently assign name for control access. You can use the auto-assigned name or customize it. Q-SYS will automatically check all Code Names in the design to ensure name is unique.
Script Access
Defines whether the component will be accessible by script and/or externally, or not at all. Choices include All, External, None (default), and Script.
- None (default) - Not accessible by any script, plugin, or by Q-SYS Remote Control Protocol (QRC).
- Script - Can be accessed by scripts, such as Text Controller, Block Controllers, and plugins only.
- External - Can only be accessed by 3rd party controls systems using component commands from the Q-SYS Remote Control Protocol (QRC).
- All - No restrictions, can be accessed by 3rd party control systems via Q-SYS Remote Control Protocol (QRC), or script objects or plugin objects.
Tip: Use Script Programmer Mode to quickly view the Script Access setting directly on the component in the design schematic without the need to disconnect from the Q-SYS Core processor.
TX Bytes
Displays a running total of the number of transmitted bytes of data.
RX Bytes
Displays a running total of the number of received bytes of data.
Reset

Output |
Check the pinout of any equipment, including the cable, to be connected to a Q-SYS serial port for input or output. In many cases, you can solve serial communication problems by inserting a null modem adapter or cable to swap the TX and RX pin positions. The TX pin on one end must be connected to an RX pin on the other end (and vice versa) for data to flow properly.
