Microphone Control - Shure DDS 5900 Manual

DDS 5900 Digital Discussion System
Example: When a 'mic_on' command results in a microphone being turned on, the CCU replies with a 'mic_on'
command. On the other hand, if a 'mic_on' command does not lead to turning on a microphone, the CCU does not
produce any reply.
There can be several reasons for the CCU to reject turning on a microphone:
• The microphone is already on
• The microphone is no longer connected to the system
• Speak list is already full ('max_speakers') and delegate interrupt is not 'on'
Retrieving System Status
The CCU supports streaming of status. When an External Control issues a 'mic_status' or 'audio_status' com-
mand, the CCU responds by sending the microphone system status. The same applies to 'audio status'. There-
fore, it is possible for an External Control to synchronize with the CCU status.

Microphone Control

Commands from External Control to DIS-CCU
Turn on microphone
mic_on <seat no><CR>
Instruct the CCU to turn on the microphone at seat_no.
If the CCU turns on the microphone, it replies with the 'mic_on' command. If the microphone also appeared in the
request list, it is taken out of the request list and the CCU issues the 'mic_request_off' command.
Turn off microphone
mic_off <seat no><CR>
Instruct the CCU to turn off the microphone at seat_no.
If the CCU turns off the microphone, it issues a 'mic_off' command.
Turn off all the delegate microphones
mic_all_delegates_off<CR>
Instruct the CCU to turn off all delegate microphones.
A Chairman is not turned off.
The CCU responds to the command by issuing the 'mic_off' command for each microphone that is turned off.
