gbz is group-base-zone 1 to 249; on 8-zone increments (eg: 1, 9, 17... ) (see note 9)
gzd is group-zone-definition 0 to 255 (each bit specifies 1 of 8 zones, starting at gbz) (see note 9)
bzn is base-zone of switcher 1 to 249; on 4/8/16-zone increments (eg: 1, 5, 9, 13, 17, 21, 25, 29, 33,... )
or 0 (0=all-switchers on daisy-chain) (see note 11)
swt is switcher-type 1 = stereo-audio, 2 = composite-video,
3 = stereo-audio/composite-video, 4 = HD-component-video
mst is machine-state 0 = normal, 1 to 7 for preset, paging, or dynamic use (see note 11, 12, 13)
pst is preset/page-state 1 to 7 (see note 11, 12, 13)
msg is message-enable 0 = no messages, 1 = normal zone-route messages (see note 11, 13)
tpr is taper-enable 0 = fast-routing, 1 = normal routes with volume tapering (see note 11, 13)
Routing Notes:
Note 1 -- Audio-only route commands (may use Zone-0) (*CW,11):
- to audio-only switcher: route audio, update audio state, send audio mssg
- to video-only switcher: ignore
- to a/v switcher: route audio, update audio state, send audio mssg
Note 2 -- Video-only route commands (may use Zone-0) (*CW,12):
- to audio-only switcher: ignore
- to video-only switcher: route video, update video state, send video mssg
- to a/v switcher: route video, update video state, send video mssg
Note 3 -- Audio/Video route commands (may use Zone-0, as appropriate) (*CW,9/10/13/14/15/16/59/60/61):
(the audio unit tracks and reports video state, and video unit is silent – eg: LE-1600A and LE-1600V together)
- to audio-only switcher: route audio, update audio AND VIDEO state, send a/v mssg
- to video-only switcher: route video, update video state -- NO MSSG
- to a/v switcher: route a/v, update a/v state, send a/v mssg
Note 4 – Audio and/or Video route commands (may use Zone-0, as appropriate) (*CW,9/10/14/15/16/59/60/61):
- Source parameters ssa and ssv may both be defined, or either may be IGNORE (to only set one source)
For IGNORE, set the parameter to 255, or, optionally, insert the ‘X’ character.
Note 5 -- Routing audio using standard route commands (*CW,9/10/11/13/59/60):
1) Routing a source when zone is currently off:
- Routes and sets zone volume to:
a) Normal (factory setting) route volume uses programmed "Zone-Initial-Volume."
b) Optionally, may configure route volume 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).
2) Routing a source when zone is currently on (skipped if source is the same):
- Routes at current zone volume.
3) Routing a source when zone is currently muted:
- Routes and unmutes to previous volume (level when zone was muted).
