The Activate-Page-State command (*CW,91,bzn,0,0,pst) changes the Current-State to paging state pst (1 to 7). Paging
always routes fast (no volume tapering), for immediate activation. 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. To terminate the page, you issue the Deactivate-
Page-State command (*CW,91,bzn,0,0,0).
A Page-State message (!S,91,bzn,swt,0,pst) is returned when paging, with state pst (1 to 7) indicating the current paging state.
When paging terminates, a Change-State message (!S,90,bzn,swt,0,mst) is returned, with machine state mst (0 to 7) indicating
the restored state.
If there are multiple switchers daisy-chained together for a large number of zones, you may direct the *CW,91 command to a
specific switcher by providing the Switcher-Base-Zone parameter bzn. If there are both audio and video switchers set to this
base zone, they both change to the new state. If bzn is set to 0, all switchers in the daisy chain change state, and all switchers
in the chain will reply with their state-change messages.
A configuration command related to paging, is *PW,230,1,3,1 – this will enable the PAGE_PB_IN contact-closure input to be
used to activate (when closed) and terminate (when open) the paging function FOR STATE-1 ONLY. This is useful for
telephone systems that provide relay contact closure during paging.
Note 13 – Preset-State-Recall command (*CW,92):
Any of the states 1 through 7 may be programmed as a Preset for a specific use, and then recalled when needed. When a
Preset (state 1 to 7) is recalled, it is copied to Normal state-0. Since state-0 it is cleared at power-up, and changed when a
new Preset is recalled, it is volatile. States 1 to 7 are stored in non-volatile memory and remain when the switcher is powered
off – they are not changed unless you explicitly alter or clear them. Each State stores the a/v route information for each zone,
left and right volumes for each zone, zone a/v status (on/off/muted), and unmute volumes for each zone.
Each of these Presets store a completely different configuration of the machine, and since they are recalled (copied) into state-
0, the presets are not changed if you subsequently change routes, volumes, etc. However, previous routes on all zones in
state-0 are lost (unlike a page, where the previous state is restored).
A preset state is programmed by using the Change-State command (*CW,90) to change to the state, apply the desired routes
and volume adjustments for the page state, and then return back to the previous working state (which is usually state-0). To
make a subsequent adjustment to a preset state (eg: change a zone volume), you simply change to the state again, make the
adjustment, and return.
The Preset-Recall command (*CW,92,bzn,0,0,pst,msg,tpr) copies the preset-state pst (1 to 7) to state-0. 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 Preset-Recalled message (!S,92,bzn,swt,0,pst) is returned, and individual zone route
messages (!S,1/2/3) may also be returned.
Note: If this command is issued when you are NOT currently in state-0 (dynamic-mode), the switcher will be placed in
state-0, and the preset then recalled. This command will also terminate any paging command in progress.
If there are multiple switchers daisy-chained together for a large number of zones, you may direct the *CW,92 command to a
specific switcher by providing the Switcher-Base-Zone parameter bzn. If there are both audio and video switchers set to this
base zone, they both change to the new state. If bzn is set to 0, all switchers in the daisy chain change state, and all switchers
in the chain will reply with their state-change messages.
