System Setup
DCS-LAN connector
In addition to the connectors mentioned in the
previous section the following connectors are
available on all units:
Two RJ45 sockets are located at the back of the
units for connecting to the previous unit (an IS 6132
Interpreter set, CS 6032 Channel Selector, DM 6xxx
Delegate Unit, DC 6990 P Conference Unit, the CU
61xx Central Unit or any other unit with a DCS LAN
connector) and to the next unit.
Connect the units using Cat 5 FTP or STP cables.
Please observe the following guide lines:
General guidelines
Connect the DCS 6000 Conference Units at the DIS-
LAN connectors to the various units using Cat 5e
FTP or STP screened cables. Please observe the
following guidelines:
•
Maximum cable length in one chain when not
using repeaters is 200 m.
•
Maximum cable length in one chain when
using repeaters is 650 m
For more details about cabling and maximum
number of units to connect to the DCS 6000 system
please consult the CU 61xx User Manual.
Settings
There are no settings to be done on the DCS 6000
conference units. The units are automatically
recognized and receive a unique address in the
system, when connected to the unique DIS digital
communication bus - the DCS-LAN.
Electrical termination of DCS LAN Network
Before powering up your DCS 6000 system, you
must ensure that the DCS LAN Network has been
properly terminated. If the last unit in a chain is a
CS 6032F the unit must have a DCS LAN Network
Termination Plug inserted in one of the two DCS
LAN Network connectors (RJ45 connectors).
If
the
network
is
communication errors on the network may occur
resulting in malfunction or degradation of the
system performance.
not
terminated
properly
•
Maximum cable length in one chain is 200
m
without
interconnection cables between the units.
The max. usable cable length depends on
the units connected and length of feeding
cables etc.
•
Maximum cable length in one chain when
using repeaters is 650 m.
If the last unit in one chain is a CS 6032 Channel
Selector, this unit has to be terminated with an
external termination, as the CS 6032 does not
have an internal termination.
4 pcs. of DCS LAN Network Termination Plug
have been shipped with your DCS 6000 Central
Unit.

Starting up the system
When the DCS 6000 Conference Units are
connected to a CU 61xx Central Unit and the
proper termination are made, the CU can be
switched ON.
After powering up the system, the light-ring in
DCS 6000 Conference Units will flash until the CU
identifies the unit. As soon as this happens, the
light-ring stop to flash and the unit is operational.
If a unit 'looses' the connection to the CU, it will
start to flash until the connection is re-
established.
Adjusting LCD contrast on units with
channel selector
The contrast on the channel selector LCD display
has been factory preset to a viewing angle of
45˚. The contrast can be changed to a different
viewing angle through the procedure described
