1 Installation This section describes how to install the base station 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 section before beginning the installation. 1.1 Personal Safety 1.1.1 Lethal Voltages The base station may be fitted with an internal AC power supply unit.
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 base station 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 base station can reach temperatures of up to +80°C (+176°F). 1.1.
Figure 1.1 Typical antistatic bench set-up conductive wrist strap dissipative rubber bench mat common point ground (building ground or mains ground via 1MΩ series resistor) 1.2.2 Antenna Load The base station has been designed to operate safely under a wide range of antenna loading conditions. However, we strongly recommend that the transmitter should always be operated with a suitable load to prevent damage to the transmitter output power stage. 1.2.
1.3.2 FCC Compliance1 This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. 1.3.3 Unauthorised Modifications Any modifications you make to this equipment which are not authorised by Tait Electronics Ltd. may invalidate your compliance authority’s approval to operate the equipment. 1.3.
1.4 Environmental Conditions 1.4.1 Operating Temperature Range The operating temperature range is –30°C to +60°C (–22°F to +140°F) ambient temperature for the 25W base station and –30°C to +50°C (–22°F to +122°F) ambient temperature for the 50W and 40W base stations. Ambient temperature is defined as the temperature of the air at the intake to the cooling fans. 1.4.2 Humidity The humidity should not exceed 95% relative humidity through the specified operating temperature range. 1.4.
1.6 Recommended Tools It is beyond the scope of this manual to list every tool that an installation technician should carry.

■ ■ ■ ■ ■ a distance of 5cm minimum clearance to any obstruction to the front of the tray. an open area of at least 50cm2 (8sq.in.) per tray of ventilation slots or louvres in front of the air intakes for the fans for each tray; for example ten 6×85mm (0.25×3.3in.) slots will allow the recommended airflow. a distance of 10cm minimum clearance to any obstruction to the rear of the tray. an open area of at least 50cm2 (8sq.in.
Disposal of Packaging 1.8.2 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 CFCand HCFC-free and may be burnt in a suitable waste-to-energy combustion facility, or compacted in landfill. Power Supply Options The base station is available with or without an internal AC power supply unit.
1.8.3 Mounting the Base Station Figure 1.3 1. Fit the base station 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 1.3 on page 14. 2. The base station can be wall-mounted by rotating the front mounting brackets and fitting the optional rear brackets (TBBA03-01).
1.8.4 Cabling We recommend that you route all cables to and from the base station along the side of the cabinet so the cooling airflow is not restricted. Cables should be well supported so that the connectors or terminals on the base station and on the ends of the cables do not have to support the full weight of the cables. Cables must be routed so that they do not restrict the air outlets at the rear of the base station. 1.8.

2 Connections This section gives an overview of looms and cables, and describes the specifications and pinouts of the external and internal connectors. Overview Figure 2.1 provides an overview of the connections.
2.1 External Connectors Figure 2.2 shows the external connectors: Figure 2.2 External connectors (configuration with internal AC Power supply unit shown) programming/microphone connector (PROG/MIC) AC power connector AC Power Connection serial data connector (IOIOI) system connector (SYSTEM) DC power connector (13.8VDC 13A MAX) ground receiver transmitter point antenna antenna connector connector (TX/ANT)* *Tx/ANT is Tx and Rx, if the duplexer is fitted.
DC Power Connection The base station is designed to accept a nominal 13.8V DC, with negative ground. Note The base station will not charge the battery via the DC power connector when an internal AC power supply unit is fitted. The DC power connector (J105) at the rear of the base station is a heavyduty M4 screw terminal connector suitable for many forms of connection. Pin Signal Name Signal Type 1 13.
The RF input to the base station is via the RX connector (N-type) on the rear panel of the base station. The RF output is via the TX/ANT connector (N-type) on the rear panel of the base station. RF Connections (RX and TX/ANT) The RF connector is an N-type connector with an impedance of 50Ω. Important Pin B Signal Name Signal Type 1 RF RF analog 2 GND RF ground Notes C rear view 20 The maximum RF input level is +27dBm. Higher levels may damage the radio.
System Connector (SYSTEM) The system connector (J106) at the rear of the base station is a 25-way standard-density D-range socket. Pin 1 2 B C D E F G H I J 1) 1! 1@ 1# 1$ 1% 1^ 1& 1* 1( 2) 2! 2@ 2# 2$ 2% 3 4 5 6 7 Signal Name Rx line output + Tx/Rx digital input 1 (AUX_GPI1) Tx/Rx digital input 2 (AUX_GPI2) Rx line output – Tx line input + Tx/Rx digital input 3 (AUX_GPI3) Tx/Rx digital input 4 (AUX_GPIO4) Signal Type audio output input transformer isolated line <6dBm high ≥1.7 V, low ≤0.
Serial Data Connector (IOIOI) The serial data connector (J1054) labelled IOIOI is a 9-way female D-range connector, which provides a data connection to the base station.
2.2 Internal Connectors 2.2.1 Transmitter and Receiver Connectors The internal connectors of the transmitter and receiver are the same for both modules. Note Whilst the internal connectors may be physically similar, the signals on the user interface connectors are different for the transmitter and the receiver. RF Connectors The RF connectors of the transmitter and the receiver are N-type connectors with an impedance of 50 Ω.
The auxiliary connectors of the transmitter and receiver are 15-way standard-density D-range sockets.

2.2.2 SI Board Connectors The two DC power connectors (J102 and J103) on the SI board are heavyduty M4 screw terminals. J102 (if fitted) accepts power from the internal AC power supply unit. J103 distributes the DC power to the transmitter and the receiver. DC Power Connectors Pin Signal Name Signal Type 1 Tx and Rx 13.
The system interface connector (J100) to the receiver is a 16-way surfacemounted connector.
