System Setup
General guidelines
Connect the PS 6000 to the various DCS 6000 units
using Cat5 or Cat5e FTP or STP screened cables.
Please observe the following guidelines:
•
Maximum cable length in one chain is 200
m
without repeater. 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 output on the PS 6000 have a
125W supply, this 125W power is not all
usable with long cables, as there will be a
voltage drop in the feeding cable from the
PS 6000 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 (Max.
Number of units to be connected)
•
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.
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
