General guidelines

DIS-LAN connectors to the various units using Cat
5 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 60xx 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. The last unit in each chain
must have a DCS LAN Network Termination Plug
inserted in one of the two DCS LAN Network
connectors (RJ45 connectors).
If the network is not terminated properly
communication errors on the network may occur
resulting in malfunction or degradation of the
system performance.
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 60xx 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˚.
