DIS Digital Conference Systems
CU 6105 Central Unit
Description
The CU 6105 is a system controller in the DCS 6000 Digital
Conference System. The CU controls everything from small systems with only a few conference units to large systems with many
conference units, channel selectors, interpretation and voting
facilities.
It supplies power to the conference units and interpreter units. It
operates up to 500 conference units and 150 interpreter units in a
single bus cable structure known as the DCS-LAN; a proprietary
high-speed digital audio, data and power bus. All units are daisy
chained using CAT 5e (or higher) F/UTP or U/FTP cables.
The CU 6105 features fully digital audio transmission of the floor
channel and up to 16 interpretation channels. Up to 8 conference
microphones can be open at the same time. The units can be divided into four groups using a built-in group matrix.
The CU 6105 features two analog audio inputs and four analog
audio outputs. The four analog audio outputs are used for distribution of audio from four groups of units, the floor channel or the
interpreter channels. This is used either for connection to external
PA systems, for recording purposes or for connection to a language distribution systems like the DIS Digital Wireless Infrared
System.
The audio from the built-in loudspeakers in the conference
units is routed from Group A and/or from the ‘Audio In 1 or 2’.
Connections for Emergency Evacuation Message (EEM) is available using ‘Audio In 2’ and a contact closure switch.
The OLED display on the front of the unit enables the user to
setup basic system configurations in terms of maximum number of
speakers/requests, microphone operation mode etc.
The CU 6105 provides TCP/IP communication over Ethernet. All
system settings from a web browser interface, which also features
simple microphone control. For more advanced controls, SW 6000
Conference Management Software is available. The CU 6105
also provides a simple to use protocol for external control over
Ethernet.
The DCS-LAN chain can be branched using repeater RP 6004 or
extension unit EX 6010. Additional units can be powered using
power supply PS CU with power inserter PI 6000 or extension
unit EX 6010. Inserting JB 6104 junction boxes in the DCS-LAN
chain enables hot plug of single units. Each JB 6104 junction box
features connection of a single unit to each of the four outputs on
the junction box.
Features
The CU 6105 has the following 'out-of-the-box' features:
• Digital audio transmission
• Daisy chain topology with loop-through connections or star topology using
junction boxes or repeaters
• DCS-LAN connection uses shielded CAT 5e (or higher) F/UTP or U/FTP
cabling
• Control of up to 50 conference/128 interpreter units (expandable - see below)
• Up to eight open microphones/up to four interpretation channels
• Support for three microphone modes; Automatic, FIFO and Manual and three
interrupt modes
• 'Auto off' option for microphones
• Scrambled audio to avoid eavesdropping
• Powers up to 60 units without an extra power supply (depending on unit type)
• Four analog audio outputs (group out or interpretation channels out)
• TCP/IP Ethernet connection for browser control, SW 6000 and third party
external control (AMX, Crestron etc.)
• Multi-language web browser for system configuration, microphone/request list
control and basic operational parameters
• Built-in table for attaching seat numbers/names to units using a browser
By installing a feature license for the CU 6105, additional features are available:
• Control of up to 500 conference units
• Up to 16 interpretation channels
• Voting (One to five buttons in combination with DC 6990P or CUA) and
Attendance Check
• Microphone operation mode VOX (voice activation)
Using the SW 6000 Conference Management Software, even more features can
be made available like the following:
• Additional voting functionality (passed/not passed and quorum formulas,
delegated votes, manual results)
• Conference facilities including agenda handling, delegate details and reports
• Mimic operation
• Message handling
• Chip card registration
• Multi-language user interface
• Mix of microphone operation modes in one system
