HDA800(V2) Serial Protocol, Version 1.3, 9/12/13 33
Basic Control
Basic Command Definitions
‘P’ Power Control
Turn on / off, or toggle the power state of the HDA800(V2):
^P 0$ Turn off power if power is not locked on.
^P 1$ Turn on power.
^P 2$ Turn off power regardless of “locked” state.
^P 3$ Turn on power and lock it on -- only a “P 2” command can turn off power.
^P +$ Toggle power
^P ?$ Query for current setting
Response String:
^=P n$
Where:
n = Current power status, 0=Off, 1=On, 3=Locked On. (A value of ‘2’ is never returned.)
The power lock and unlock can be used to keep a controller from turning off the HDA800(V2).
Drivers should be written to only use the “P 0” and “P 1” commands to turn on and off the
HDA800(V2). This allows users to override the driver’s logic by manually issuing the “P 2” and “P 3”
commands.
By issuing a “P 3” command (lock power on), the HDA800(V2) will be turned on, and locked. Only a
subsequent “P 2” command will turn off the HDA800(V2), The “P 0” and “P 1” commands will be
ignored.
‘SZ’ Set Zone(s) -- Audio Switch
This is the command used to map sources to any number of zones on the audio switch.
Its different forms are:
^SZ @ zone,@zone,in$ Map all channels of an source, to a zone or zones.
^SZ. ch @zone,in$ Map only the selected channels of sources to zones.
^SZ. ch @zone,+$ Sequence zones forward through sources.
^SZ. ch @zone,-$ Sequence zones in reverse through sources.
^SZ ?$ In polled mode, reads current settings of all logged changes.
^SZ @ zone,?$ Read current settings of given zones.
^SZ. ch @zone,?$ Read current settings of the selected channels of zones.
Response Strings:
^=SZ @ zone,in$ or,

@ zone = One (or more) zones to be mapped.
in = Source to map to given zone(s).
ch = Channel bitmap.
