System Setup
General guidelines
Connect the CU 6005/6010/6011 to the various
DCS 6000 units using Cat5 or Cat5e FTP or STP
screened cables.
The operation of the DCS 6000 units is found in the
User Manual for the specific units.
Please observe the following guidelines:
• Maximum cable length in one chain is 200
m (before repeating). This includes
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.
• Although the DCS-LAN Network Output
connectors (CU 6005: A1 plus A2, CU
6010/6011: A1, A2, B1 or B2) have a
125W supply, this 125W power is not all
available with long cables, as there will be
a power drop in the feeding cable from the
CU 6005/6010/6011 to the units connected.
If the feeding cables are short and the
cables between the units are short, more
units can be connected than if the feeding
cable is long and/or the cables are long
between the units. Please consult the next
section ‘Maximum number of units to be
connected’.
• The maximum number of languages
configured on chain A (A1 or A2) or B (B1
or B2) is 16. If more languages are
required, Interpreter sets for those
languages have to be divided between both
chains (A and B) – this is only applicable
for the CU 6010/6011. Normally the
languages are supposed to be divided
equally on chains A (A1 or A2) and B (B1
or B2).
• 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
automatic termination.
It is desirable that the square of the feeding cables
especially but also the interconnection cables are as
big as possible to minimize the voltage drop in the
cables. Cat 5/Cat5E cables are delivered in various
gauges:
The following table is showing the Diameter/square
for various AWG types:
Type Diameter Square
AWG22 0.64 mm 0.32 mm2
AWG23/1 0.57 mm 0.25 mm2
AWG24 0.53 mm 0.22 mm2
AWG26 0.42 mm 0.14 mm2
Built into 19” Racks
The unit has a built-in fan taking air in at the right
side of the unit and blowing the hot air out at the
right side. That allows units in 19” racks to be
stacked close with other units without extra room
for cooling air between them. Please check that the
other units will allow this.
