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.
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.
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.
1.3.4 Health, Safety and Electromagnetic Compatibility in Europe In the European Community, radio and telecommunications equipment is regulated by Directive 1999/5/EC, also known as the Radio and Telecommunications Terminal Equipment (R&TTE) directive. The requirements of this directive include protection of health and safety of users, as well as electromagnetic compatibility. Intended Purpose of Product This product is an FM radio transceiver.
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).
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 1.7.1 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.
Figure 1.2 Typical cabinet ventilation requirements top view b 20cm (8in) side view front view 2U c c e d ≥17.
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.
1.8 Installing the Base Station System Caution 1.8.1 Unpacking the Equipment Unpacking the TB8100 BSS Figure 1.3 A TB8100 subrack complete with modules can weigh up to 28kg (62lb), or up to 30kg (66lb) complete with packaging. We recommend that, once the equipment is out of the carton, you remove the modules from the subrack before moving the equipment again. Otherwise, have another person help you with the lifting. In all cases follow safe lifting practices.
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 g so that the BSS is the right way up with the cushion on top h. Remove the cushion from the top of the BSS i. If you do not need to keep the packaging, we recommend that you recycle it according to your local recycling methods.
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 1.8.
1.8.4 Optional Slide Mounting Rails You can also use TBA2141 slide mounting rails b when 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. Figure 1.6 Optional slide mounting rail - rear view c b Important 1.8.
Figure 1.7 below shows two recommended methods of securing these cables to prevent straining either set of terminals. Figure 1.
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 b on the rear panel.
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.
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.
the rear of the PA. Connect the other end to the auxiliary DC input connector d at the rear of the reciter. Note Method 2 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 e on the reciter, link digital out 1 to +AUX_V. 1. Connect one end of the Power Saving control cable b to the Power Saving control connector c at the rear of the PA. 2. Cut the socket off the other end of the cable.
2.3 System Connections The standard system interface board is fitted to reciters bearing the product code TBA4xxx-0A0x. If purchased separately, it has the product code TBA10A0. It provides the following: Standard ■ non-isolated 600Ω balanced audio I/O ■ Tx key ■ high impedance unbalanced audio I/O ■ Tx relay ■ digital I/O (2 outputs, 6 inputs, 4 bi-directional) ■ Rx gate ■ RSSI It is fitted with a 25-way female D-range connector and a 4-way auxiliary DC input connector.

TaitNet RS-232 This system interface board is fitted to reciters bearing the product code TBA4xxx-0L0x or TBA5xxx-0L0x. If purchased separately, it has the product code TBA10L0. It is designed for use with MPT trunking systems, and also for use with multiple base station systems.
port switch) and modem or radio modem. Refer to TN-906 for more details on using an APS with TB8100 base stations. 2.4 Service Kit Connections The TB8100 Service Kit is connected to the BSS via the RS-232 serial port on the control panel. This port is a 9-way female D-range connector. Use a straight through cable, as supplied with the Service Kit, to connect your programming computer to the BSS. The pin allocations for the serial port are given in the following table.
2.5 RF Connections 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.
