<strong>DCN</strong> Data Brochure | Introduction |5contribution equipment at any desired point in the systemcabling. These easy-to-connect accessories are usedfor both fixed and portable installations, making <strong>DCN</strong>a versatile system that can be installed quickly and efficientlyin any conference situation.1.2 Contribution equipmentContribution equipment is the term used to describethe units via which participants can contribute to aconference. Depending on the type of contribution unit,participants can access facilities to listen, speak, registera request-to-speak, receive screen messages, hold conversationswith other participants via an intercom, takepart in electronic voting sessions and receive simultaneousinterpretation of the floor language.<strong>DCN</strong> Discussion units are specially tailored for smallergatherings and meetings, and offer a high level of functionalityand digital convenience, as well as their owndistinctive styling.The twin-coaxial cable and 6-pole connectorsSimplified wiringGone are the days of complex wiring through bulkytrunking. The diagram above shows the cable used for<strong>DCN</strong> signal transmission, and the specially moulded6-pole connectors (configured according to the 6-pinDIN standard).The same cable is used to transport signals to allcontribution units throughout the system, and canbe ‘tapped’ at any desired point to connect extracontribution units or other <strong>DCN</strong> equipment, thusgiving rise to a ‘branched-tree’ topology.In this way, future extensions to the system capacity,such as adding extra microphone units or increasingthe number of language channels, do not require alterationsto the existing system cabling. The power is alsosupplied to all units via two wires in the same cable.Installation is further simplified and speeded up by theuse of splitters and ready-made cables with sturdy,moulded connectors, thus allowing easy insertion ofTable-top Concentus unitsfor portable and flexible installationsThe most basic Concentus Contribution unit isequipped with a microphone with an on/off button,loudspeaker, voting keys and LED status indicators.More advanced units incorporate features such asgraphic LCD screens, language channel selectors,softkeys and chip-card readers. Chairman units havea microphone priority system that temporarily mutesall active delegate microphones.
