Tuning and Configuration
If your TB8100 BSS has not been tuned to your requirements at the factory, you will need to tune
the reciter modules before operating them in your radio system. To do this you will need to use
the Calibration Kit software included on the Product CD, plus the TB8100 calibration test unit.
The TB8100 BSS has been programmed with a default software configuration and default
passwords at the factory. You will need to use the Service Kit software to configure your BSS to
suit the requirements of your radio system. Refer to the Calibration Kit and Service Kit
documentation for full details on these procedures.

1 Installation
This chapter describes how to install the TB8100 BSS in a standard 19 inch
rack or cabinet. It also provides some general information on safety
precautions and site requirements. We recommend that you read the entire
chapter before beginning the installation.
1.1 Personal Safety
1.1.1 Lethal Voltages
Warning!! The PMU contains voltages that may be lethal.
Refer to the ratings label on the rear of the
module.
The TB8100 BSS must be installed so that the rear of the PMU is located
in a service access area. The PMU must be connected to the mains supply
source by trained personnel in accordance with local and national
regulations.
Disconnect the mains IEC connector and wait for five minutes for
the internal voltages to self-discharge before dismantling. The AC
power on/off switch does not isolate the PMU from the mains. It
breaks only the phase circuit, not the neutral.
The PMU should be serviced only by qualified technicians. There are no
user-replaceable parts inside. If the PMU is damaged and does not function
properly, stop the module safely and contact your nearest Tait Dealer or
Customer Service Organisation immediately.
All servicing should be carried out only when the PMU is powered through
a mains isolating transformer of sufficient rating. We strongly
recommend that the mains power to the whole of the repair and test area
is supplied via an earth leakage circuit breaker.
1.1.2 Explosive Environments
Warning!! Do not operate TB8100 BSS equipment near
electrical blasting caps or in an explosive atmos-
phere. Operating the equipment in these envi-
ronments is a definite safety hazard.

1.1.3 Proximity to RF Transmissions
Do not operate the transmitter when someone is standing within 90cm (3ft)
of the antenna. Do not operate the transmitter unless you have checked that
all RF connectors are secure.
1.1.4 High Temperatures
Take care when handling a PMU or PA which has been operating recently.
Under extreme operating conditions (+60°C [+140°F] ambient air
temperature) or high duty cycles the external surfaces of the PMU and PA
can reach temperatures of up to +80°C (+176°F).
1.2 Equipment Safety
1.2.1 ESD Precautions
Important This equipment contains devices which are susceptible to
damage from static charges. You must handle these devices
carefully and according to the procedures described in the
manufacturers’ data books.
We recommend you purchase an antistatic bench kit from a reputable
manufacturer and install and test it according to the manufacturer’s
instructions. Figure 1.1 shows a typical antistatic bench set-up.
You can obtain further information on antistatic precautions and the dangers
of electrostatic discharge (ESD) from standards such as ANSI/ESD
S20.20-1999 or BS EN 100015-4 1994.

1.2.2 Antenna Load
Important The PA may be damaged if the load is removed or switched
while the PA is transmitting.
To protect the PA output stage from load transients (i.e. switching or
removing the load), we recommend that you fit an isolator between the PA
and the load. Fit the isolator as close as possible to the RF output connector
on the PA. Do not connect any switching or combining equipment
between the isolator and the PA.
1.2.3 Equipment Grounding
To ensure safe operation the TB8100 BSS equipment must be correctly
grounded as described in these installation instructions.
1.2.4 Installation and Servicing Personnel
The TB8100 BSS should be installed and serviced only by qualified
personnel.
1.3 Regulatory Information

1.5 Grounding and Lightning Protection
1.5.1 Electrical Ground
The TB8100 BSS modules are grounded by physical contact between the
module case and the subrack. To ensure a good ground connection you
must tighten each module retaining clamp securely (refer to “Replacing
Modules” in the Installation and Operation Manual for the correct torque).
A threaded grounding connector is provided on the rear of the subrack for
connection to the site ground point (refer to “Connection” in the
Installation and Operation Manual for more details).
1.5.2 Lightning Ground
It is extremely important for the security of the site and its equipment that
you take adequate precautions against lightning strike. Because it is outside
the scope of this manual to provide comprehensive information on this
subject, we recommend that you conform to your country’s standards
organisation or regulatory body.
1.6 Recommended Tools
It is beyond the scope of this manual to list every tool that an installation
technician should carry. However, the following tools are specifically
required for installing the TB8100 BSS:
■Pozidriv PZ3 screwdriver for the M6 screws used in the DC input
terminals on the PMU; M6 screws are also used to secure the subrack to
the cabinet in Tait factory-assembled systems
■Pozidriv PZ2 screwdriver for the M4 screws used to secure the module
retaining clamps
■0.25in or 6mm flat blade screwdriver for the fasteners used to secure the
front panel to the subrack
■8mm AF spanner for the SMA connectors.
You can also obtain the TBA0ST2 tool kit from your nearest Tait Dealer or
Customer Service Organisation. It contains the basic tools needed to install,
tune and service the TB8100 BSS.

8 Installation TB8100 Installation Guide

1.7 Ventilation
Always ensure there is adequate ventilation around the TB8100 BSS. Do
not operate it in a sealed cabinet. You must keep the ambient temperature
within the specified range, and we strongly recommended that you ensure
that the cooling airflow is not restricted.
Important The cooling fans are mounted on the front panel and will
only operate when the panel is fitted correctly to the front
of the subrack. To ensure adequate airflow through the
BSS, do not operate it for more than a few minutes with the
front panel removed (e.g. for servicing purposes).
1.7.1 Ambient Air Temperature Sensor
The ambient air temperature reading
for the TB8100 BSS is provided by
the ambient air temperature sensor
board bfitted to the PA control
board.
The sensor board is inserted through
slots in the control board and heatsink
to be positioned between the heatsink
fins.
Important If the sensor board is to provide accurate ambient tempera-
ture readings, it must have forced airflow and must not
come into contact with the metal of the heatsink fins. Do
not stack PAs with the fins together. It is possible for
the fins on one heatsink to slide between the fins on the
other heatsink. This can damage the sensor board, and pos-
sibly result in the heatsink fins becoming locked together.
1.7.2 Cabinet and Rack Ventilation
Refer to Figure 1.2 on page 9.
The cooling airflow for the TB8100 BSS enters through the front panel and
exits at the rear of the subrack. For optimum thermal performance, the
heated air that has passed through a BSS must not be allowed to re-enter the
air intakes on the front panel. Any space at the front of the cabinet not
occupied by equipment should be covered by a blanking panel.

To allow enough cooling airflow through a cabinet-mounted BSS, we
recommend the following:
■an area of at least 150cm2(23in2) of unrestricted ventilation slots or holes
in front of the air intakes for the fans for each subrack; for example,
thirty 6x85mm (0.25x3.3in) slots will allow the recommended airflow
■a vent in the top of the cabinet with an area of approximately 150cm2
(23in2) per subrack, or a similar area of ventilation per subrack at the rear
of the cabinet behind each subrack
■a 2U gap at the top of the cabinet.
Note The ventilation opening must be unrestricted. If the slots or holes
are covered with a filter, mesh or grille, the open area must be
increased to allow the same airflow as an unrestricted opening.
The maximum ambient temperature entering the cabinet must not exceed
+60°C (+140°F).
If the TB8100 BSS is installed in a rack or cabinet with other equipment
with different ventilation requirements, we recommend that the TB8100 be
positioned below this equipment.
Auxiliary Extractor
Fans The TB8100 BSS does not require auxiliary extractor fans mounted in the
top of the cabinet. If your cabinet is already fitted with fans, the following
procedures apply:
■if there are six or more 120mm (4.75in) fans, each capable of extracting
160m3per hour (94.2CFM), they must run continuously
■if there are fewer than six fans, you must remove them and ensure the
vent in the top of the cabinet has an area of approximately 150cm2
(23in2) per subrack.
If you have any other configuration, the performance of your system will
depend on how closely you comply with the TB8100 BSS airflow
requirements described above.

1.8 Installing the Base Station System
Caution A TB8100 subrack complete with modules can
weigh up to 28kg (62lb), or up to 30kg (66lb) com-
plete with packaging. We recommend that, once
the equipment is out of the carton, you remove the
modules from the subrack before moving the equip-
ment again. Otherwise, have another person help
you with the lifting. In all cases follow safe lifting
practices.
1.8.1 Unpacking the Equipment
Unpacking the
TB8100 BSS The TB8100 BSS is packed in a strong corrugated cardboard carton with
top and bottom foam cushions. To prevent personal injury and damage to
the equipment, we recommend that two people unpack the BSS.
1. Cut the tape securing the flaps at the top of the carton and fold them
flat against the sides b.
2. Rotate the carton carefully onto its side cand then onto its top d,
ensuring that none of the flaps is trapped underneath.

3. Slide the carton upwards over the foam cushions and lift it away e.
Remove the cushion from the bottom of the BSS f.
4. Rotate the BSS and cushion carefully over the rear of the BSS gso
that the BSS is the right way up with the cushion on top h. Remove
the cushion from the top of the BSS i.
Disposal of
Packaging If you do not need to keep the packaging, we recommend that you recycle
it according to your local recycling methods. The foam cushions are CFC-
and HCFC-free and may be burnt in a suitable waste-to-energy combustion
facility, or compacted in landfill.
1.8.2 Mounting the Subrack
Caution We recommend that you remove the modules from
the subrack before lifting it (refer to “Replacing
Modules” in the Installation and Operation Manual),
or have another person help you with the lifting.

1. Remove the front panel by undoing the fasteners with a quarter turn
anti-clockwise, as described in “Replacing Modules” in the
Installation and Operation Manual.
2. Fit the subrack into the cabinet or rack and secure it firmly with an
M6 (or 0.25in if you are using imperial fittings) screw, flat and spring
washer in each of the four main mounting holes b, as shown in
Figure 1.4 on page 12.
Note If you need extra mounting security, there are additional mount-
ing holes cprovided at the rear of the subrack for auxiliary sup-
port brackets.
1.8.3 Auxiliary Support Bracket
TBA2140 auxiliary support brackets can be fitted to the rear of the TB8100
subrack to provide additional mounting security. Figure 1.5 below shows a
standard TBA2140 bracket bfitted in a typical Tait Electronics cabinet c.
If you are not using a Tait cabinet, you may have to make your own brackets
to suit your installation.
Important You must fit the auxiliary support brackets if you intend to
transport a cabinet fitted with a fully built-up TB8100 BSS.
We also recommend that you fit the brackets under the following
conditions:
■when the installation is in an area prone to earthquakes
■when third party equipment is installed hard up underneath the TB8100
BSS subrack.
Figure 1.5 Auxiliary support bracket

1.8.4 Optional Slide Mounting Rails
You can also use TBA2141 slide mounting rails bwhen mounting the
TB8100 BSS in a cabinet, as shown in Figure 1.6 below. These rails will
support the BSS while you slide it into the cabinet.
However, you must still secure the BSS to the cabinet with four M6 (0.25in)
screws through the main mounting holes on the front of the subrack, as
shown in Figure 1.4 on page 12.
Important The slide mounting rails are not suitable for transporting a
cabinet fitted with a fully built-up TB8100 BSS. In this
case, you must also fit the TBA2140 auxiliary support
brackets to the upper set of rear mounting holes c.
1.8.5 Cabling
General We recommend that you try to route all cables to and from the TB8100 BSS
along the side of the cabinet so the cooling airflow is not restricted.
DC Power Cabling DC power cables should be well supported so that the terminals on the
PMU and on the ends of the cables do not have to support the full weight
of the cables.

2 Connection
2.1 Auxiliary Power Supply Connections
PMU Auxiliary DC
Output The PMU can provide an auxiliary DC output when it is fitted with the
optional auxiliary power supply board. This board is available with an
output of 13.65VDC, 27.3VDC, or 54.6VDC (depending on the model),
and is current limited to 3A, 1.5A or 750mA respectively. This optional
power supply is available on the auxiliary DC output connector bon the
rear panel. DC from this output can be supplied to the +AUX_V pin on
the system interface connector con the reciter via the auxiliary DC input
connector don the system interface board (see “Reciter Auxiliary DC
Input from PMU” on page 18). The auxiliary DC power cables eare
described in “Power Supply Connections” in the Installation and Operation
Manual.
The auxiliary power supply is configured with the Service Kit (Configure >
Base Station > Miscellaneous > Power configuration > Auxiliary power
control). Its operation can be controlled by Task Manager statements, for
example:
IF Digital input 01 active THEN Enable auxiliary supply.
Refer to the Service Kit documentation for more details.
We do not recommend connecting two or more auxiliary power supply
boards in parallel to increase the current supply to external equipment. In
this situation, the auxiliary board with the highest voltage will try to supply
all the current required, until it goes into current limit and the voltage
reduces to the level where another board will begin to supply power.
Running an auxiliary board continuously in current limit will reduce its life
span and reliability. Also, if one auxiliary board fails or is switched off when
a base station is powered down for some reason, the remaining auxiliary
boards will be unable to supply the required current and will go into current
limit, possibly causing the external equipment to shut down.
Figure 2.1 Auxiliary DC power supply connections
b
c
de

TB8100 Installation Guide Connection 17

It is, however, acceptable to connect two or more auxiliary power supply
boards in parallel (e.g. for redundancy), as long as the current consumption
of the external equipment is less than the rating of one board. This means
that, even if only one auxiliary board is functioning, it will still be able to
supply the current requirements of the external equipment.
Two different types of auxiliary DC output connector have been fitted to
the PMU. The pin allocations for the 8-way connector fitted to PMUs
manufactured before August 2004 are given in the following table. Note
that pins 1 to 4 and pins 5 to 8 on this connector are linked.

Reciter Auxiliary DC
Input from PMU The system interface board in the reciter has an auxiliary DC input
connector. DC from the auxiliary DC output on the PMU can be supplied
to the +AUX_V pin on the system interface connector via this input (see
“PMU Auxiliary DC Output” on page 16).
The pin allocations for the auxiliary DC input on the system interface board
are given in the following table. Older boards use the 4-way connector,
while the TaitNet RS-232 board and all other boards manufactured after
March 2005 use the 2-way connector. Note that pins 1 & 3 and pins 2 & 4
on the 4-way connector are linked. Refer to “System Connections” on
page 20 for the pin allocations for +AUX_V on each system interface board.
The DC output from the PMU is 13.65VDC, 27.3VDC, or 54.6VDC
(depending on the model). Although this power output is isolated, the
negative side of the supply is grounded on the system interface board to give
a +V output.
2.2 12V PA Power Saving Control Connection
To enable Power Saving in the 12V PA, you must connect digital out 1 on
the reciter’s system interface connector to pin 1 of the Power Saving control
connector on the rear panel of the PA. Once this connection is made, the
PA will shut down whenever the reciter goes into Deep Sleep mode. For
more information on the operation and configuration of Power Saving, refer
to “Power Saving” in the Installation and Operation Manual.
Note When a base station with a 12V PA is configured for Deep Sleep,
digital out 1 is dedicated to Power Saving control and should not
be used for any other Task Manager function.
Two ways of making the Power Saving control connection between the 12V
PA and reciter are described below. The circled numbers in the following
instructions refer to Figure 2.2 on page 19.
Method 1 1. Connect one end of the Power Saving control cable b(Tait part
number 219-02971-00) to the Power Saving control connector cat

the rear of the PA. Connect the other end to the auxiliary DC input
connector dat the rear of the reciter.
Note If you are using an older reciter with a 4-way connector, you will
need to use Method 2.
2. On the D-range plug that is fitted to the system interface connector
eon the reciter, link digital out 1 to +AUX_V.
Method 2 1. Connect one end of the Power Saving control cable bto the Power
Saving control connector cat the rear of the PA.
2. Cut the socket off the other end of the cable. Connect the wires
directly to the D-range plug fitted to the system interface connector
eas follows:
■red - digital out 1
■black - ground.
The pin allocations for the Power Saving control connector on the PA are
given in the following table.
If you wish to make up your own cable, use the following connector for
both the PA and reciter connections:
