Zone Status
Whenever a Zone Status query is issued or if the Zone Activity Auto Update function is
enabled and something about the zone changes, a Zone Status Report will be sent. The
automatic Zone Status Report will be sent one second after zone activity stops. The
metadata is also sent whenever it changes. The Zone Status Report is a string of characters
that conforms to the various RS-232 Commands above. The format of the string is as
follows:
#{z#}ZS VO{v#} PO{0 / 1} MU{0 / 1} IS{0 / 1}+
Following is an example of a Zone Status Report string:
#6ZS VO8 PO1 MU0 IS0+
This is interpreted as Zone 6 (#6ZS) is powered on (PO1), has the volume level set to 8
(VO8), audio muting off (MU0), and with the BUS as the audio input (IS0).
