Voting Control - Shure DCS 6000 User Manual

Command Structure (from DIS-CCU to
External Control)
Command lines out of the DIS-CCU are just as simple:
<command><SP><data><CR><LF>
<SP> Space - 0x20 = 32
<CR> Carriage return - 0x0D = 13
<LF> Line Feed - 0x0A = 10
Again, to satisfy most systems, the CCU terminates
command lines by including both <CR> and <LF>.
Seat Numbering
Microphone units are identified by means of a seat
numbers. Each unit is assigned a seat number. This is
done automatically for all conference units, when they
are connected to the DIS-CCU. The DIS-CCU Browser
interface is used to change seat numbering.
Seat numbers must be in the range from 1 to 65535.
DIS-CCU Reply to Commands
Generally, a command from an external application is
replied to by the CCU. But, reply to a command is produced
only if actions are taken by the CCU due to the command.

Voting Control

The external control interface features control of voting
sessions and attendance check sessions in the Central
Unit. And only if the feature license 'Voting' is uploaded in
the DIS-CCU.
Voting configurations
Two different configurations must be considered:
• DIS-CCU controlled by SW 6000
• DIS-CCU not controlled by SW 6000 (standalone)
Retrieve voting sessions
No matter which configuration applies, it is possible for
an external controller to request a list of voting sessions
- using the command 'voting_status'. The CCU will reply
by returning the list of voting sessions currently applicable
(either SW 6000 defined voting sessions or build-in voting
sessions).
SW 6000 controlled
SW 6000 supports a number of voting sessions. Via
the external control protocol, it is possible to make two
requests:
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' command,
the CCU responds by sending the microphone system
status. The same applies to 'audio status'. Therefore, it is
possible for an External Control to synchronize with the
CCU status.
• Start one of the SW 6000 defined voting sessions
• Start SW 6000 default voting session
Standalone The CCU features
4 build-in voting sessions in standalone mode:
• 3-button voting
• 3-button secret voting
• 5-button voting
• 5-button secret voting
