4.1.1 CU Interface Description
① Menu display
A 2x20 character OLED-display enables system
configuration without a computer.
② Navigation Buttons
5-button keypad for configuring the system without a
computer.
③ Power Button
The power button turns on or off the central unit. All
connected discussion units and power supplies will
automatically power on.
• Green = powered on
• Red = powered off but connected to power supply
• Off = no power supply is connected to the unit
④ Power Supply Connector
Threaded connector secures to the PS CU power supply.
⑤ Chain outputs
Two RJ45 jacks are available for connecting the discussion
units, forming the DCS-LAN. The DCS-LAN chain safely
carries digital audio, control data, and power over the
same cable. The CU operates a single mix from the two
separate discussion unit chains, enabling more flexible
installations and system connections.
Important: Only connect DDS 5900 discussion units to this output.

⑥ Control Connector (TCP/IP)

system like AMX
⑦ Audio Outputs
Four balanced, male XLR connectors for connection to
PA systems, audio mixers, audio recorders, or a language
distribution system.
⑧ Audio Inputs
Two balanced, female XLR connectors for connecting
wireless microphones, processed audio signals, an
emergency broadcast message (EEM), or music during
meeting breaks.
• Input 1: Connect an additional audio source; gain is adjustable.
• Input 2: Connect an Emergency Evacuation Message (EEM)
audio signal.
⑨ Emergency switch connector
A terminal block connector for a 'normally open' switch.
When the switch is closed, the audio signal on the 'In 2'
connector is distributed to all output channels, overriding
all other audio inputs.
Note: There is no volume control available for setting the volume on 'In 2'. The
volume has to be set at the equipment generating the "Emergency Evacuation
Message (EEM)" audio signal.
