RS232 Queries
Zone Activity and Zone Status
ZA – Zone Activity Auto Update Enable Command. Format - !ZA{0/1}+
ZS – Zone Status Query. Format - ?(z#}ZS+
Zone Activity Auto Update Enable Command
The Activity Update will cause the system to send out the complete Zone State whenever something in
the zone changes. The State string will be sent out one second after activity in the zone stops. Also, the
Metadata will be sent out whenever it changes.
Zone Status Query
The Zone Status Query will cause the system to send out the full Zone State string along with the Zone
Metadata string(s), for the specified zone.
IMPORTANT NOTE: Also, use the highest baud rate that the receiving system can support.
When the Amplifier sends out complete Zone Status, (either due to an explicit query or due to an Auto
Update, the data is formatted a bit differently than the standard responses to a Command or Query.
All of the Zone Info / Zone Status output lines will begin with the character ‘#’ (the sharp, or number
sign).
The format of the Zone State is:
#{z#}ZS VO{v#} PO{0/1} MU{0/1} IS{0/1}+
An example:
#6ZS VO8 PO1 MU0 IS0+
This line tells us the following info about Zone 6:
Zone Volume – 8
Power – On
Mute – Off
Input Select – Bus
