Q-LAN Receiver

• Each Core must be set to the same PTPv2 Domain in the Design Properties. If the domains are not set to Custom, and you attempt to run the design, an error message is displayed indicating that the clock is not set correctly.

• The Q-LAN TX and RX components support unicast streams only: one transmitter can stream to one receiver. For a multicast option, see System Link.

Note: The number of signal pins is variable and set in the component's Channel CountProperty.

Input Pins

This component does not have any input pins.

Output Pins

Output 1 - n

Audio signal pins are represented by a () circle, and traditional wiring is represented by a thin black line.

By default, the Q-LAN Receiver component is set to 8 outputs. You can choose between 1 and 16.

Q-LAN Receiver Properties

Name

User-defined name given to the Receiver. This must be the same name as the Q-LAN Transmitter from which the Receiver gets the audio transmission. You cannot have duplicate Q-LAN Receiver Names on the same network.

The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', the hyphen, and the underscore. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.

Location

User-defined name that groups the receiver with other components in the same physical location, or in the same organizational scheme.

Dynamic Stream Name

When enabled, the Stream Name field in the Control Panel can be edited.

Channel Count

Number of channels for the Receiver. This count must match that of the Transmitter.

Is Redundant

Enable this property if the Q-SYS Core is connected to both LAN A and LAN B for network redundancy.

Note: For the Q-SYS Core 110f and 110c, each Q-LAN Receiver with this property enabled consumes two streams instead of one. Use File > Check Design to see your design's Network Audio Input count.

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.

Stream Tab

Q-LAN

Peak Input Level (dBFS)

Meters for each channel indicating the peak input level.

Digital

Invert

Toggle button to invert the digital output of the Q-LAN Receiver.

Mute

Mutes the output signal.

Gain (dB)

Controls the Gain of the digital output signal.

Status

OK LED

LED indicating the status of the Receiver network link for both LAN A and LAN B (If network redundant).

Status

Component status is conveyed with the Status LED and Status box, which uses both color and text to indicate the current condition:

• OK: The device is functioning normally.
• Initializing: The device is in the process of a firmware or configuration update, or the design is starting.
• Compromised: The device is functioning, but a non-fatal problem exists. Refer to the Status box for details.
• Missing: The device cannot be discovered.
• Fault: The device is malfunctioning or is not properly configured. Refer to the Status box for details.
• Unknown: This status appears during a Core reboot (for example, during a firmware update), or when a design is being uploaded to the Core and before it has started running.
• Not Present: If applicable to the device, this status appears when the device is not connected to the network and its Is Required component property is set to 'No'. This status also appears if the device component's Dynamically Paired property is set to 'Yes', pairing has not been assigned in Core Manager, and the device component's Is Required property is set to 'Yes'. See Dynamic Pairing.

Connection

Stream Name

The Stream Name identifies the connection between a Q‑LAN Transmitter, and a Q‑LAN Receiver. They must have the same Stream Name.

You can leave the Q‑LAN Receiver or Transmitter at the default setting, but at least one must be set to Dynamic Stream Name = yes in the Properties then rename the stream to match the other.

Primary OK 

This LED indicates if the Primary Stream is OK or not.

Backup OK 

If your Core is redundant, you can choose to have your Q‑LAN receiver / transmitter redundant.

This LED indicates if the Backup Stream is OK or not.

Network Rx 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.

Details Tab

LAN A / LAN B

Details

Text indicating the Details of the receiver stream. The information in this field is updated regularly and is cumulative. The information is displayed as running totals. Below is an example of some of the possible data.

• connected

Q-LAN Bandwidth Compile Error

You cannot achieve both max stream and channels at the same time. The max stream count needs to be 256 to allow 256 single-channel streams. Configurations of 256x2 thru 256x16 all exceed line bandwidth.
