connected to the system and their displays will show labels and other
information.
Using both transceiver ports, a basestation may be connected with up
to two transceiver/antennas via a direct connection with the
basestation. For the best, most reliable coverage, it is advisable to use
a minimum of two transceiver/antennas in any installation, positioned
in different locations in the coverage area. When more FS-TA’s are
required to support a larger coverage area or more wireless beltpacks,
an antenna splitter will need to be introduced between the basestation
and the transceiver/antennas.
Note: In some situations, particularly in outdoor venues,
interference from non-DECT sources can severely reduce
the range of the system. In these cases we recommend a
site survey as described in Chapter 8, “Installing a System”.
CONNECTING TRANSCEIVER/ANTENNAS WITH A
SPLITTER (PD2203)
A splitter (PD2203) will connect up to five transceiver/antennas to one
of the transceiver ports on the FreeSpeak basestation, creating up to
five coverage zones that can be overlapped to make large areas
where FS-BP wireless beltpacks can have continuous coverage. The
use of the splitter also extends the distance that the FS-TA transceiver
antennas can be located from the basestation to 2,000 metres (6,400
feet) if 24AWG cable is used or 1.000 metres (3,200 feet) if 26AWG
cable is used (assuming the same type of cable to used to connect the
antenna to the splitter and the splitter to the basestation).
Note: It is recommended that shielded CAT-5 cable is used.
For example, a splitter can be used to connect to a FreeSpeak
basestation that is located in a production truck outside an arena or
stadium, with a single CAT-5 cable going to the splitter which is then
located just inside the stadium. From that splitter, up to five FS-TA
transceiver/antennas are distributed throughout the stadium to create
wide coverage – each with a run of CAT-5 cable back to the splitter. A
similar arrangement may be used in a large theatre or performing arts
facility.
The connection between a transceiver port on the FreeSpeak
basestation and a PD2203 splitter is accomplished with standard
4-pair CAT-5 data cable with RJ-45 connectors. It is connected to the
port labeled MATRIX on the splitter. This cable can be as long as
1,000 metres (3,200 feet) if 24AWG cable is used or 500 metres (1,600
feet) if 26AWG cable is used. The splitter must be locally powered via
its DC IN connector, using the in-line external universal power supply.
The RJ-45 ports on the splitter labeled “1” through “5” are the
connections to the FS-TA transceiver/antennas. Transceiver/antennas
connected to the splitter can be powered at a distance of up to 300
