Introduction Central control equipment
Chapter 4. Central Control
Equipment
4.1 Introduction Central control equipment
The Central Control Unit (CCU) is at the heart of the DCN system, and has control facilities for up
to 240 contribution units, such as delegate and chairman units, interpreter desks, as well as audio and
multipurpose interface units. The CCU can function with or without a central operator using a PC.
Stand-alone systems
For use in smaller systems where an operator is not essential, the Central Control Unit type
LBB 3500/05 is used as a ‘stand-alone’ unit providing basic microphone operational modes, basic
parliamentary voting procedures, and facilities for organizing interpretation channels and basic
intercom functions. A dedicated RS 232 port is used for automatic camera control (default) and can
also be set for ‘test and diagnostic’ purposes.
PC control
For use in larger systems requiring a central operator, Central Control Units type LBB 3500/15 and
LBB 3500/35 are used allowing a PC to be used as the interface between an operator and the DCN
system. A wide range of Windows based DCN application software modules are available to run on
the PC to provide comprehensive facilities for conference control and management. Each CCU has a
dedicated built-in RS232 port for ‘DIRECT’ connection to a PC ( the PC does NOT require a PC-
Network card LBB 3510/00). See Chapter 5. DCN Control using Personal Computers.
IMPORTANT: (D) versions are intended for the North American market only.
All controls and indicators described for DCN Control equipment (i.e. LBB 3500/05,
LBB 3500/15, LBB 3500/35, LBB 4106/00 and LBB 3508/00) are also valid (unless
mentioned) for (D) type versions with the exception of the ‘power supply’.
See Chapter 4.4.1.
