Adjusting Parameters - Polycom SoundStructure C16 Design Manual

This acknowledgement uses the same syntax as the vcgdef command, but with the vcglist action. The
<label> argument is a user-defined text argument indicating the name of the virtual channel group, and zero
or more <vcmember> arguments will indicate the virtual channel members of the virtual channel group.
The acknowledgement will only be sent to the control interface on which the command was received.
As an example, consider a system where we have defined a virtual channel group as follows:
vcgdef "all zones" "zone 1" "program audio" "zone 2"
vcgremove "all zones" "program audio"
vcgadd "all zones" "zone 3"
If we now send the following vcglist command,
vcglist "all zones"
Then SoundStructure will send the following acknowledgement to the interface on which the vcglist
command was received.
vcglist "all zones" "zone 1" "zone 2" "zone 3"

Adjusting Parameters

Parameters are adjusted by executing commands on a SoundStructure device. There are three types of
commands: system parameter commands, virtual channel commands, and matrix commands. These
commands adjust the corresponding parameter type as described previously. The general syntax for all
parameter commands is given in this section.
Parameter Command Syntax
All parameter commands have the following syntax.
<action> <param> [<limit>] [<chan> [<chan>]] [<index> [<index> ...]] [<arg>]<term>
Some examples of parameter commands are given below.
get sys_sw_ver 1
set mic_in_gain "DVD Audio" 10
set fader max "DVD Audio" 10
inc fader "DVD Audio" 2
tog aec_en "Mic 1"
set eq_en "Speaker 1" 1
set peq_gain "Speaker 2" 1 -2.5
set matrix_gain "DVD Audio" "Codec Output" 0
authenticate "admin" "456"
run "Power-On"
The fields in the command are described below.
