Knox Video RSIII - Manual (Page 24)

Where x is a letter in the range A to H. This corresponds to Zone Groups A through Zone Group
H, and aa,bb, etc. are a list of two-digit output numbers in square brackets, separated by commas
(no spaces) for that Zone Group. The list can include any number of outputs from 01-16. Any
output may be included in any Zone Group.
To see a list of the outputs assigned to any group, send the command
$Zx$D [ENTER]
Where x=A to H.
To clear all the Zone Groups send the command
$Z$C [ENTER]
This command will clear ALL outputs associated with ALL zones and not the settings of the
outputs.
Once a Zone Group has been established, VTB commands may be sent in common to all the
outputs in the group. To send a Zone Group VTB command, send $Z followed by the command
stripped of its output number. For example, a three-step volume increment command would
normally be $Vxx3+, where xx is the output number. To send the command to all the outputs in
Zone Group A, omit the output number and precede the command with a $ZA. So the full
command for the above example is $ZA$V3+. The different zone commands are summarized:
$Za [xx,xx,...,xx] Create Audio Zone a (A-H) xx=output number
$Za$V00 Set Full Volume in Zone a (A-H)
$Za$Vuu Set Absolute Volume (uu) in Zone a (A-H)
$Za$V+ Increment Volume in Zone a (A-H) by 1
$Za$V- Decrement Volume in Zone a (A-H) by 1
$Z$D Dump Audio Zone configuration
$Z$C Clear All Audio Zones
3.4.4 AUDIO STATUS AND CONFIGURATION COMMANDS
3.4.4.1 DISPLAY OR DUMP COMMAND
To determine the condition of the VTB setting use the $D of the form:
$D [ENTER] Dump all outputs
$Dx [ENTER] Dump individual output channel
$Dxx [ENTER]
$Dxxx [ENTER]
Where x is the output channel to be displayed.
3.4.4.2 CLEAR COMMAND
To set the VTB channels to their default values use the $C command of the form:
$C [ENTER] Clear ALL VTB output channels
$Cx [ENTER] Clear VTB channel x output
$Cxx [ENTER]
$Cxxx [ENTER]
$Cvuu [ENTER] Sets ALL VTB output channels to uu
Where x is the output channel and u is an absolute volume level.
