Polycom SoundStructure C16 Design Manual page 513

all commands that are sent to SoundStructure start with the Null character which will not be interpreted as
a valid command.
To resolve this issue, select the CR-LF transmission termination option within the Tera Term user interface
when using telnet connections. When using Tera Term in serial mode, either CR or CR-LF line terminations
operate properly.
What Does The Error "invalid action specified" Message Mean?
Typical actions for a command include the values of set, get, inc, dec, tog to respectively set, get, increment,
decrement, or toggle the value of a parameter. If the action is not typed properly or is not in lower case, this
error message may occur. Correct the syntax or case and try again.
What Does The Error "device ID not specified" Message Mean?
For commands that require a device ID to be specified, not including the device ID will cause this error
message. As an example, sending the command:
get ser_baud
will generate this error message. The proper syntax for this command is
get ser_baud 1
where 1 is the device ID of the SoundStructure system.
To resolve this issue, adjust the syntax of the command to include the device ID.
What Does The Error "virtual channel or virtual channel group label not quoted" Message
Mean?
When a virtual channel name is used in a command, it must be surrounded with double quotes. If the virtual
channel name or virtual channel group name is not in double quotes, then this error message will occur. For
example, the command
set mute Table Mic 1 1
will cause this error message. Fix this syntax by putting double quotes around the virtual channel name such
as with the command
set mute "Table Mic 1" 1
and the system will work properly.
What Does The Error "no virtual channel or virtual channel group with that label exists"
Message Mean?
If an API command references a virtual channel name that doesn't exist then this message will be received.
Correct the spelling of the virtual channel name, or create the virtual channel if it doesn't exist, and try again.
What Does The Error "invalid parameter name" Message Mean?
If the API command sent to the SoundStructure device is not correct, perhaps due to a typo on the command
or the improper syntax used, the SoundStructure device will return with an error 38.
What Does The Error "parameter argument not specified" Mean?
If the command syntax of the command is not followed such as specifying too many parameters or not
enough parameters, this error message may occur. As an example, setting the baud rate of a
SoundStructure device requires specifying the device ID as in the following example.
