Conference System
Figure 6.57: Circuit diagram
The first request to speak slowly activates parallel output D00 of the data distribution board.
The second request (from a different interpreter booth) activates parallel output D01, the
third request activates parallel output D02 etc. The maximum number of activated parallel
outputs is eight (D00 to D07).
Help signaling
The interpreter desks (DCN-IDESK) have a Help button. With this button, the interpreters can
activate an indicator that tells the operator or chairman that they need assistance. This
function of the interpreter desk must always be used along with the data distribution board.
Refer to the figure for the physical connections.
