Note 6 -- Routing audio using Route-Muted commands (*CW,14/61):
1) Routing a source when zone is currently off:
- Routes and places zone in muted state, and sets unmute volume to:.
a) Normal (factory setting) unmute level uses programmed "Zone-Initial-Volume."
b) Optionally, may configure unmute level to be "Previous" volume.
(this was level when zone was last turned off)
(the implementation actually updates Zone-Initial-Volume at every zone turn-off,
then this route-muted command loads unmute levels from initial).
2) Routing a source when zone is currently on (skipped if source is the same):
- Routes at current zone volume.
NOTE: DOES NOT MUTE IF ZONE IS ON
3) Routing a source when zone is currently muted:
- Routes and leaves zone in muted state.
- Unmute level will be previous volume (level when zone was muted).
Note 7 -- Routing audio using Route-At-Volume commands (*CW,15):
1) Routing a source when zone is currently off:
- Routes and sets zone volume to specified volume level.
2) Routing a source when zone is currently on:
- Routes at specified volume level (if source is the same, just updates volume).
3) Routing a source when zone is currently muted:
- Routes and unmutes to specified volume level.
Note 8 -- Routing audio using Route-At-Volume-Muted commands (*CW,16/61):
1) Routing a source when zone is currently off:
- Routes and places zone in muted state, and unmute level will be specified volume level.
2) Routing a source when zone is currently on (NOTE: DOES NOT MUTE IF ZONE IS ON):
- Routes at specified volume level (if source is the same, just updates volume).
3) Routing a source when zone is currently muted:
- Routes and leaves zone in muted state, and unmute level will be specified volume level.
Note 9 -- Routing using Group commands (*CW,59/60/61):
Group commands apply to a group of eight consecutive zones, as defined in the command by gbz and gzd. Parameter gbz is
group-base-zone, and gzd is group-zone-definition, which define a group of up to eight zones. If the group is defined such
that the zones are on different switchers, the returned messages will collide and be garbled – therefore, gbz should be
restricted to 8-zone increments (1, 9, 17…). 4-zone switchers can be used if they are installed on 8-zone increments.
Routes are reported for each zone defined in the group.
Each bit in gzd corresponds to one of eight zones, with bit-0 (LSB) being the lowest zone, and the bit-7 (MSB)
being the highest zone. If the bit is 1, the zone is included in the group, and if the bit is 0, it is excluded.
The first zone (selected by bit-0) is defined as group-base-zone gbz. The next seven bits in gzd correspond to the
next seven zones above gbz. For example, if gbz = 9 and gzd = 155, the group includes zones 9, 10, 12, 13, and 16.
First, choose gbz, then to select the appropriate gzd, you need to set the gzd bits corresponding to the desired zones.
Zone gzd-bit bit-value 1=included add bit-values
9 = gbz bit-0 1 1 (lsb) 1
10 bit-1 2 1 2
11 bit-2 4 0 0
12 bit-3 8 1 8
13 bit-4 16 1 16
14 bit-5 32 0 0
15 bit-6 64 0 0
16 bit-7 128 1 (msb) 128
= 10011011 = 155 = gzd
Therefore, when we choose gbz = 9, and set the appropriate bits in gzd to include zones 9, 10, 12, 13, and 16 in
the group, we need gzd = 155. You can get this gzd either by converting the binary value 10011011 to decimal,
or by adding the bit-values that correspond to the included zones (128+16+8+2+1 = 155).
For testing clusters, use the group commands but set gbz to cluster 1 to 8, and gzd to 0.
