【
Chairman platform
】
To get awider and farther coverage area within 5 meters
height, HCS-5300TW/80 digital infrared transceiver is
strongly recommended for the meeting place where the
height is lower than 5 meters, such as chairman platform.
Figure 3.18 Planning the transceiver (chairman platform)
【
Balcony venue
】
In a balcony venue, with a higher ceiling and the
shielding from the gallery, the transceiver planning must
depend on the height of the ceiling and the style of seating.
For example, HCS-5300TH/80 can be used to
communicate
with the units on the chairman platform and the ground
floor for the area not shaded by the balcony.
Figure 3.19 Planning the transceiver (balcony venue)
3.4.3 Planning the path from main unit to
transceiver
3.4.3.1 Cautions for cable connecting
The distances between main unit and every
transceiver must be equal
If the footprints of two transceivers overlap, the
conference unit can receive infrared signals from more
than one transceiver. As described in section
1.4.5
,
overlap effect or multipath effect will occur: the intensity of
the receiving signals is enhanced if the two signals have
the same phase; but the intensity of the receiving signals
will weaken if the two signals have the reverse phase.
To avoid multipath effect, the distance between the main
unit and all transceivers must be equal. As shown in the
following figure, all cables for "A" must be identical in
length when the transceivers are installed in the same
space.
Figure 3.20 Without distributors, all the cable lengths must
be equal
Cable length between main unit and transceiver
should not exceed 60 m
Cable length A should not exceed 60 meters in the
previous figure.
Avoid parallel cabling of high voltage (power)
cables and the cables between the infrared
transceivers and the main unit
Communication between infrared transceivers and the
main unit may be interfered by high voltage. To reduce
the risk of interference, avoid parallel cabling with high
voltage cables (includes mains voltage). If this cannot be
avoided, please shield the cable with iron pipe.
