Chapter 4. Central Control Equipment

4.1Introduction 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.
