The DIS-CCU Central Control Unit is the centerpiece of the
DDS 5900 Digital Discussion System and the DCS 6000 Digital
Conference System. It distributes digital audio, control data, and
power to chairman, delegate, and interpreter units over a standard
shielded CAT 5e (or higher) cable in serial ‘daisy-chain’ topology
using the proprietary DCS-LAN protocol.
The DIS-CCU includes 2 analog audio inputs for external
audio sources, and 8 analog audio outputs for connection
to a videoconferencing system, audio/video recorder, sound
reinforcement system, or wireless language distribution system.
The DIS-CCU distributes the ‘floor’ audio mix plus interpretation
channels to each discussion or conference unit. Up to 8
microphones may be active simultaneously. Four different
microphone operating modes are supported: Automatic, First-In/
First-On (FIFO), VOX (voice activated), and Manual.
A web browser interface allows microphone control and system
configuration using a computer or tablet. Separate web addresses
are provided for Administrator, Chairman, and Display functions.
A TCP/IP connection is provided for connection to a third-party
media control system.

Description
DCS 6000 Operating Mode
As shipped, the DIS-CCU can control up to 250 DDS 5900-series discussion units and 32 interpreter units. When
Feature License FL6000 has been installed, the DIS-CCU can be used with either DDS 5900 discussion units or
DCS 6000 conference units (but not both at the same time). Additional Feature Licenses are available to expand
the system:
•FL6000-3800
Allows control of conference units for up to 3,800 participants and 200 interpreters (with optional hardware)
• FL6000-INT-8, FL6000-INT-16, FL6000-INT-31
Allows expansion to 8, 16, or 31 languages
The DCS-LAN connection can be branched using the RP 6004 Repeater or EX 6010 Extension Unit. Additional
conference units can be powered using the PI-6000-XX DCS-LAN Power Kit or by the EX 6010. Inserting JB 6104
Junction Boxes in the DCS-LAN chain enables hot-plugging up to 4 discussion or conference units.
