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 SoundStruc-
ture 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 specify-
ing the device ID as in the following example.
set ser_baud 1 9600
If the device ID is not specified, such as with the following example:
set ser_baud 9600
then this error message will occur.
What Does The Error “invalid parameter argument” Message Mean?
If the argument for the command is not correct, for instance trying to set the
mute state of microphone to the value 3 when the only valid values are 0 or 1,
then this error message may occur.
Why Won’t The Control System Mute The Microphones?
Check that the command from the control system isn’t generating one of the
error message described above. Next ensure that the control system is con-
nected to the SoundStructure device over RS-232 or Ethernet and able to send
commands to the SoundStructure device.
If muting the microphones by using the default virtual channel group “Mics”,
the syntax of the command should be:
