Dynamic-State Mode

In Preset-Recall mode (described above), you are simply copying the preset information to volatile state-0 memory, and then remaining

in the normal mode. You do not change states 1 to 7 when using preset mode.

In Dynamic-State mode, you can change your Current-State to any of the machine states, 0 to 7. When you in are a state other than 0,

changes you make (routes, volume adjusts...) are immediately saved to the non-volatile state memory.

For example, you may use states for different family members, should they desire the dynamic aspect of the configuration, as opposed

to them loading a fixed preset. Changed routes and volumes will remain when they return to the state next time.

Caution: in Dynamic-State mode, any changes to the Current-State are immediately saved, so you do not want to allow a user to

change to a state that is storing a preset or paging configuration – you are relying on preset and page states to be static after they are

programmed.

The Change-State command (*CW,90,bzn,0,0,mst,msg,tpr) changes the Current-State to mst (0 to 7). The msg parameter allows you

to enable individual zone-route messages if desired, and tpr selects either normal routing (with volume tapering), or fast routing (no

tapering). Using the bzn parameter, you may direct the command to a switcher at a specific Base-Zone, or to all switchers on the daisy

chain. A State-Change message (!S,90,bzn,swt,0,mst) is returned, and individual zone route messages (!S,1/2/3) may also be returned.

A Change-State command will also terminate any paging command in progress.

Paging/Doorchime/Camera Interrupt Mode

Any of the states 1 through 7 may be programmed for use in Interrupt-mode, for example, to page from a telephone-system (or

microphone), sound a doorchime, or route security cameras and annunciators. Interrupt-mode only uses a state temporarily – it may be

activated when needed, and, when it is deactivated, the previous state is restored. While paging is only one application of Interrupt-

mode, we also refer to this as Paging-mode, since this is the most common use.

In a typical paging/doorchime application, the page state will define, for each zone that is to receive the page, the volume levels as well

as the routes to those zones. The page/chime audio source is typically connected to the highest source on the switcher (eg: 8 or 16),

although any source may be used. The page state is programmed to route this paging source to the desired zones, at the desired paging

volume levels.

Flexibility: You may wish to have different paging states for upstairs, downstairs, outside, etc.

An important distinction: Unlike the Dynamic-State mode, which changes the entire machine's current state and affects all zones,

during paging/doorchime use you do not want to turn off zones that are not getting the page/chime, but instead leave those zones as

they are (on, off, or muted). Therefore, zones that are programmed off in the page state will be unaffected by the page operation.

Zones that are not to receive the page remain as they are, whether off or listening to music, etc. This would not be the case if you

simply changed state in Dynamic-State mode, since the off zones would actually turn off.

Another important distinction: Note also that when the page is terminated, the original state is restored – there is no additional

programming required to implement this powerful function.

Yet another important distinction: To prevent any undesired changes to the page state, when paging, any routes, volume, or other

commands are disabled for the duration of the page. Also, only one page may be active at a time (you may not page from a page).
