WIRING THE ANTENNAS AND SPLITTERS
To wire antennas and splitters:
1. Run 4-pair CAT-5 cable from the Eclipse base to the antenna or
splitter, and determine that the antenna or splitter is showing both
power (green LED lit) and signal (yellow LED lit when the matrix is
on).
Note: To meet FCC emissions requirements, you must fit a ferrite
on any CAT-5 cable plugged into either of the two ports
labeled “tranceivers.” The ferrite should be fitted at the
E-Que card end of the CAT-5 cable. Position the ferrite as
close to the E-Que card as possible.
The manufacturer of the ferrite is Wurth Elektronix. The part
number is 742 711 32.
2. Run 4-pair CAT-5 cable from the splitter to each of the
transceiver/antennas.
3. Make sure that the local power supplies are plugged into the
antennas, unless they are close enough to the matrix to draw power
from the attached CAT-5 cable.
You will know that a transceiver/antenna has sufficient power from the
cable if the green power LED and the yellow data LED light up. If you
have several longer runs and are attempting to power the
transceiver/antennas from the base / splitter connection, check each
one again when the are all connected. The local powering for the
transceiver/antenna is recommended in most cases to provide the
most reliable long-term Eclipse installation.
Note that 4-pair CAT-5 cable with RJ-45 connectors on each end is
specified for connection between the E-Que card and the
transceiver/antennas. Use of other cable can result in markedly shorter
distances of cable runs and other possibly other performance
problems.
During the initial system setup, before walking through the system with
a beltpack to check for gaps in coverage, it is wise to avoid
“permanently” installing the transceiver/antennas. Hold them in place
in some temporary way until their optimal position is determined.
DETERMINING COVERAGE AREAS
After you have initially set up the transceiver/antennas and splitters,
you can proceed to test the coverage areas and re-locate antennas
and splitters, if necessary, for optimal coverage.
To determine coverage areas:
1. Once the base, splitter(s), and transceiver/antennas have been
placed and wired, turn on a beltpack (assuming that it has been
registered with ECS) and walk the coverage area – ideally speaking
