I/O-22 Status Component

The I/O-22, in the Q-SYS Designer Inventory list, represents a physical piece of equipment.

The physical I/O-22 is an Input/Output device. Analog input sources can be connected to the I/O-22 and the analog audio is converted to digital audio and sent over the Q-LAN network to the Core for Processing. Likewise, digital audio can be sent from the Core over the Q-LAN network to the I/O-22 which converts the digital signal to analog for local use.

The I/O-22 in the Inventory list has several components under it that are placed in the Schematic for use in your system.

This Topic covers the Status component of the I/O-22.

Controls

I/O-22 Status

Control

Function

Default / Range

When the ID/Identify button, in the Q-SYS Designer Status component, or the Configurator's Network Configuration for the hardware,or on the physical hardware is pressed, the ID buttons in the Configurator and Status component flash, and the LED on the physical Hardware flashes to indicate the association between the three.

The indicators will flash for 5 minutes unless you stop them by pressing any one of the buttons.

Off / On

Status LED

This LED changes color to indicate the current status of the I/O-22. See Status for the meanings of the various colors.

N / A

Status

Displays the current status of the I/O-22 both in text and color. The following is a list of possible status colors, and some example conditions.

NOTE: These conditions are examples, and may not be applicable to all components with a Status field.

OK – Green – (0) – Audio is good, hardware is good.

Compromised – Orange – (1) – Audio is good but a redundancy mechanism is active (one LAN down but the other is still up) or a non-fatal hardware problem exists (fans too slow, temperature higher than expected, etc.)

Fault – Red – (2) – Audio is not passing, or hardware is malfunctioning or mis-configured (amplifier power off, audio streams broken, wrong type of I/O Card installed, loudspeaker short circuit, etc.)

Missing – Red – (3) – A piece of hardware, defined in the design, has not been discovered. Audio is not passing through that piece of hardware.

Initializing – Blue – (5) – In the process of firmware, configuration update, and design start. Audio is obviously bad.

Not Present – Gray – A virtual component in the design, that is designated as Dynamically Paired, and Not Required ,has no hardware assigned to it.

Temperature

Text field indicating the current temperature inside the associated I/O-22, measured in Celsius. Typically about 60° C.

Power

These four LEDs indicate which power source is being used for the I/O-22.

Control	Function	Default / Range
POE A	PoE A (LAN A) is supplied by a POE switch, or an injector. Produces 2 - 3 W average power, 8-10 W peak power from the loudspeaker for ~ 10 seconds	N / A
POE B	PoE B (LAN B) is supplied by a POE switch, or an injector. Produces 2 - 3 W average power, 8-10 W peak power from the loudspeaker for ~ 10 seconds
POE A Plus	PoE A Plus (LAN A) is supplied by a POE Plus switch, or an injector. Produces 8-10 W Average output power from the loudspeaker.
POE B Plus	PoE B Plus (LAN B) is supplied by a POE Plus switch, or an injector. Produces 8-10 W Average output power from the loudspeaker.
Aux Power	Aux Power is 24 VDC, 30 W, 1.25 A, supplied by an external power supply. Produces 8-10 W Average output power from the loudspeaker.

Audio Streams

To see both input and output Audio Streams information, you must have cards installed in the slots giving both inputs and outputs. For example, a Line Input card gives you Input Audio Streams, a Line Out card gives you Output Audio Streams.

N / A

1. Notes:

In Input and Output Audio Streams, accept_count = (early + on_time). This is OK, everything else should be zero.

The units are 16 samples, so accept_count should go up by 3000 per second.

too_early, too_late, very_late indicate clock sync problems. If Clock Offset is larger than a single digit, check the QoS configuration on the switches for the clock traffic (the highest priority DSCP). If too_late or very_late are not zero but the Clock Offset is zero or very small, check the QoS configuration on the switches for the audio traffic (the second highest priority DSCP).

missing_count could mean network problems such as bad cables, check the CRC error counters on the switches.

Properties

I/O-22

The following properties are set when the I/O-22 in the Inventory list is selected. They are also available, with the exception of Verbose, when any of the I/O-22 components are in the Schematic and selected.

Property	Function	Choices
Name	Identifies the I/O-22 component in Q-SYS Designer, enabling the connection between the design and the physical I/O-22. This name should be the same as the I/O-22 Device Name (hostnameHostnames may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', the hyphen, and the underscore. Hostname labels cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.) in the Configurator. Click in the Name property and type the Name. The name must follow standard naming conventions. The Administrator restricts the name according to the following: ASCII characters a - z (case insensitive) Digits 0 - 9 Hyphen (cannot be at the beginning or end of the name) Underscore (acceptable with a Q-SYS implementation) No other characters, symbols, punctuation, or blank spaces.	User input
Location	User defined Location for the I/O-22.	User input
Is Network Redundant	Determines if the I/O-22 is using redundant networks or not.
Is Required	When Is Required is set to Yes, an error displays if the hardware does not exist on the network. This is the default behavior. When Is Required is set to No, the device is identified as not present, its status state is Not Present which is not considered an error. The color displayed for “Not Present” equipment is gray. If a device is dynamically assignable but has not been assigned, it is considered Not Present” even if it is required.	Yes / No
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 Dynamic Pairing for more information.	Yes / No
Verbose	Displays the Networking and Audio Stream details for LAN A and LAN B. You must have Is Network Redundant set to Yes to see LAN B details. The Verbose property is available only when you select the I/O-22 Component in the Schematic.
