Cables
ES100 systems use CAT5E cabling or higher. Connect-
ed straight from an OUT port to an IN port - under ideal
conditions - the cable can be up to 100 meters long.
However in real life conditions are never ideal. Also
when ES100 devices are used in a touring environment
the RJ45 connectors will wear out at some moment in
time. To prevent this from happening in the middle of a
large scale pop concert it is good practise to use a patch
fi eld - e.g. with EtherCon connectors - and replace the
cables and connectors in a managed time interval.
In real life applications cables will be used-ones,
connected through Ethercon patch panels, with dim-
merpacks and high power ampracks nearby. In these
cases we advice to restrict copper cable lengths to cover
on-stage distances only, and move to fi ber connections
for longer distances such as the FOH-stagerack connec-
tions.
Connectors
For direct connection most ES100 devices have touring
grade Ethercon connectors. With patch fi elds also EtherCon
connectors and cables can be used.
A connection can be converted to multimode or singlemode
fi ber using a media converter. In the audio markets Neutrik
OpticalCon and Connex Fiberfox are the most commonly
used connectivity systems.
Frequent inspection of the connector and cable quality is
recommended - replacing them in a managed time interval
to prevent intermittent problems in the network’s connectors
from which the redundancy protocols can not recover.
With analogue audio cabling a system of male and fe-
male connectors is adopted - male for output and female
for input. Ethernet is bi-directional, so the arrangement is
different: male for cables, female for chassis connectors.
Hence, labelling cable connectors and chassis connectors is
very important, as is the training of the users of the system
to use the labelled information when connecting the system
locations.
Multiple access points & large systems
ES100 is designed for use in small and medium scale
redundant ring topology live systems. In a fi xed
installed system with many access points - such as
live systems for theatre, cultural venues and concert
halls - the ring topology is not suited as unused ac-
cess points have to be passively connected resulting
in ring segments with many passive connections. This
results in a much higher amount of failure sources
(every cable and connector is one), but also in dete-
riation of the Ethernet signal quality caused by the
many mechanical connectors in ring segments. For
multiple access point systems and for fi xed installed
systems with more than 5 active locations and/or 64
channels a double star topology using Cobranet can
be considered as an alternative.
