SquawkBox

User Manual

5 – Remote Override

The SquawkBox includes an override facility whereby the audio stream being monitored can be temporarily overridden and

switched remotely to an override audio stream. This allows the SquawkBox network to be used for pages or system

broadcasts and so on. When the override is active, a red LED will illuminate on the SquawkBox front panel, the name shown

will also switch to the name designated to the override stream, and the volume will alter to a value set specifically for the

override. Once the override is de-activated, the SquawkBox returns to the original audio stream and original volume level.

The override audio stream is configurable. Each SquawkBox has a set of default parameters for the override audio stream

(name, bundle and submap) just like the standard audio streams but with an additional volume setting that is used when the

override is activated, setting the volume for the override audio over the current volume even if the volume is muted! The

override system also facilitates use in systems where, rather than be a single override stream there are several depending on

the situation. The override audio stream can be dynamically configured by including the audio stream information in the

override activation message. This additional data supersedes any or all of the default settings stored in the unit. More

information on how to do this is in section 5.3.1.

Not only is the override audio configurable, so are which SquawkBoxes are overridden. Each SquawkBox can be configured

to be part of up to 16 different override groups. Each group may contain one or more SquawkBox devices and each

SquawkBox may be a member of multiple groups. The end result is a very flexible and powerful override system that can

target a single SquawkBox, a group of SquawkBoxes, multiple groups of SquawkBoxes or every SquawkBox on the network.

*Note: While the override is active, the volume can be changed as normal but the channel buttons have no affect.

5.1 – Override Settings

Figure 5 - Override configuration controls

Along with the default values for fields Name, Bundle and Submap, there are additional override settings and controls.

Override Volume

This volume level is automatically set when the override is activated and once the override is removed, the volume will

return to its original level.

Override Groups

The override group setting configures which of the sixteen different groups this particular SquawkBox belongs to. A

SquawkBox can be a member of multiple groups. If no groups are selected, only system wide overrides will activate the

override facility on this unit.

Override Test

The override has a test facility that can be used to activate or not activate, depending on the group settings, the device

being configured. Clicking the test button opens the override test page.
