Note 10 -- Fast-Route commands (*CW,9/59):
Routes are performed quickly, by disabling the volume-tapering that is normally applied.
Note 11 – Change-State command (*CW,90):
The switchers are usually in State-0, which is initialized to all-zones-off when the switchers power-on. If you never use any
of the state features, you simply stay in this Normal mode – in this mode, routes and other changes all occur in State-0. 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.
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. The Change-State command is used
for programming states (for use as preset or page states), or is used for Dynamic-State mode operation (which is only used
in special cases).
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.
When this command is used to program page-states or preset-states, you change to the desired page/preset state, apply the
appropriate routes and volume adjustments, and then return back to the previous working state (which is usually state-0). To
make a subsequent adjustment to a page/preset state (eg: change a zone volume), you simply change to the state again, make
the adjustment, and return.
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.
If there are multiple switchers daisy-chained together for a large number of zones, you may direct the *CW,90 command to a
specific switcher by providing the Switcher-Base-Zone parameter bzn (and, optionally, enable zone-route messages with the
msg parameter). 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, but no zone-route messages are returned (if you set msg=1). However,
all switchers in the chain will reply with their state-change messages.
Note 12 – Page-State command (*CW,91):
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.
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.
Note also that when the page is terminated, the original state is restored. 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). Error messages are return in these cases.
A page 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 page state (eg: change a zone volume), you simply change to the state again, make the
adjustment, and return.
