set mute “Mics” 1
and
set mute “Mics” 0
to mute and unmute, respectively the microphones. This command should
generate a series of command status messages that report the mute state of the
individual virtual channels that are in the virtual channel group as well as an
overall status of the virtual channel groups mute status.
Remember that the API must be in lower case and that the virtual channel
names are case sensitive.
I Muted All The Members Of My Virtual Channel Group, Why Don’t I Get A
Group Acknowledgement That The Virtual Channel Group Is Muted?
The way that virtual channels and virtual channel groups work is that when a
virtual channel group is muted or the gain adjusted, for example, all the chan-
nels in the group get are set to the same value and all the virtual channels in
the group reply with command acknowledgements reflecting their new value.
If the members of the group are set to the same value, there is no command
acknowledgement that comes from the group. The only way to get a group
acknowledgement is to send a command to the group.
Where Do I Get More Info About The API?
Appendix A in this manual describes the command API syntax and the file
soundstructure-parameters.html on the CD-ROM includes the full list of
parameters that can be adjusted for the SoundStructure devices. The full API
can be found also by pointing your web browser at the IP address of the
SoundStructure device.
Do Commands Need To Be In Upper Or Lower Case?
All API commands must be in lower case. Sending upper case commands will
cause error messages to be returned by the SoundStructure device.
Virtual channel and virtual channel group names can be in mixed case.
Remember that virtual channel names are case-sensitive - “Table Mic 1” and
“table mic 1” are two different virtual channel names.
I’ve Tried Everything And I Still Can’t Connect To The SoundStructure Device
Reboot the SoundStructure device and see if it is possible to connect to the
device either via RS-232 or Ethernet. If so, check the Polycom website for a
newer version of firmware and release notes to see what issues may be been
resolved.
