4.2. Power Connections
For permanently connected equipment, a readily
accessible disconnect device shall be incorporated in
the fixed wiring; For pluggable equipment, the
socket-outlet shall be installed near the equipment
and shall be easily accessible.
This label may appear on the bottom of the
apparatus due to space limitations.
The lightning flash with an
arrowhead symbol, with an
equilateral triangle, is intended to
alert the user to the presence of
un-insulated ‘dangerous voltage’
within the products enclosure that may be of
sufficient magnitude to constitute a risk of electric
shock to persons.
The exclamation mark within an
equilateral triangle is intended to
alert the user to the presence of
important operating and
maintenance (servicing)
instructions in the literature accompanying the
appliance.
Attention:
Equipment with or without ON/OFF
switches have power supplied to the
equipment whenever the power cord is
inserted into the power source;
however, the equipment is operational
only when the ON/OFF switch is in the
ON position. The power cord is the
main power disconnect for all
equipment.
Attention:
Installation should be performed by
qualified service personnel only in
accordance with the National Electrical
Code or applicable local codes.
Warning:
To prevent electric shock, do not use
this (polarized) plug with an extension
cord receptacle or other outlet unless
the blades can be fully inserted to
prevent blade exposure.
Warning:
To reduce the risk of fire or electric
shock, do not expose this appliance to
rain or moisture. Do not open the
cabinet; refer servicing to qualified
personnel only.

Information
5.1. General
System Architecture
5.1.1. Components
Central units
D-Cerno CU : basic central unit for D-Cerno system
D-Cerno CU-R : The D-Cerno CU-R is the exclusive
central unit for the D-Cerno system and comes with
an integrated USB recording module and web server.
The D-Cerno CU(-R) is the heart of the system
meant to control small to mid-sized meetings.
It controls 50 delegate units and can be expanded up
to 150 units by a master-slave configuration with
multiple central units. (*)
Control of the system is easy and intuitive via
the touch sensor buttons and a large LCD menu.
Next to this the D-Cerno CU-R offers also the
possibility to control and configure the system via
the integrated webserver and USB recordingmodule.
At the front of the D-Cerno CU-R units there are two
USB connections to connect a USB storage device for
direct recording of the meeting.
To guide the meeting several conference modes
are implemented. Direct access, Request, Push
to talk, FIFO and Vox control (*).
Delegate units are connected in daisy chain
over the 4 bus connections ( 4 branches or 2
closed loops). When cabled in loop, a patent
pending redundancy mechanism garantees
that the system continues to work, should a
cable break or be disconnected for some
reason.
Figure 5.1.1: D-Cerno Chairman Unit
The delegate units
D-Cerno delegate units make use of touch sensor
buttons .
The system is designed to work out-of-the box,
Wiring is easy, shielded Cat5 cables from
unit to unit. While connecting there is no
need to worry about the IN and OUT port as
the unit detects the direction of the signal
flow automatically.
There is no initialization procedure
required. After wiring the system, it is ready
for operation.

7. Central Control unit
7.1. Introduction
The D-Cerno CU is the heart of the system. It controls
all delegate units and can interconnect to other
systems either via the external audio connections
The system has a built in power supply to drive up to
50 units and can operate in a standalone mode.
Initialization and configuration can be done via the
integrated menu.
Figure 6.1: D-Cerno connectivity
7.2. Controls and
indicators
All controls are done via touch panel by means of an
intuitive user interface menu (see chapter 6.4)
A user can activate or select a control or menu item
by touching one of the symbols beneath the display ,
with his finger , without the need to push.
7.3. External Connections
1. +48V DC power connector

7.3.1. Power Supply
The power supply can operate on an inputvoltage
range of 100-240Vac , 47-63Hz.
The output voltage is 48V dc –3.15A max
8. System cables
The system cables used as connection between the
central unit and the contribution equipment, and
from unit to unit is Cat5e AWG 24 FTP shielded
cables with shielded RJ45 plugs.
Televic has standard pre-made cables available in
different lengths:
2m ICC5/2 71.60.4002
5m ICC5/5 71.60.4005
10m ICC5/10 71.60.4010
20m ICC5/20 71.60.4020
The voltage level at the output of the central unit is
48 V. Every meter of cable and conference unit in a
branch causes a voltage drop. Every unit in a branch
should receive at least 30V ??.
Delegate units will automatically shut down if the
supplied voltage is too low.
