12 Introduction TB7100 Installation and Operation Manual© Tait Electronics Limited December 20051.1 Frequency BandsThe base station is available in the following frequency bands:■66 to 88MHz (A4)■136 to 174MHz (B1)■216 to 266 MHz (D1)■400 to 470MHz (H5)■450 to 530MHz (H6)■450 to 520MHz (H7)The RF band of the base station is implemented by the frequency band of the transmitter and receiver modules. 1.2 RF Output PowerThe base station is available with 25W and 50W/40W RF output power. The RF output power options are implemented by different transmitter and receiver modules.The 25W base station is available in the following frequency bands:■A4■B1■D1■H5■H6The 50W/40W base station is available in the following frequency bands:■B1 (50W)■H5 (40W)■H7 (40W)
TB7100 Installation and Operation Manual Introduction 13© Tait Electronics Limited December 20051.3 Power Supply OptionsThe base station is available with or without an internal AC power supply.All base stations have an external DC input power connector which is used as main power supply when no internal AC power supply is fitted.When the internal AC power supply is fitted, the DC input can be used as a DC backup power option. In case of AC mains failure the base station will automatically and seamlessly switch to DC power input.If no internal AC power supply is fitted, an external Tait T809-10-87xx power supply can be used to supply the DC voltage required.Warning!! The internal AC power supply unit contains voltages that may be lethal. Refer to the ratings label on the rear of the base station.

22 Functional Description TB7100 Installation and Operation Manual© Tait Electronics Limited December 2005The block diagram illustrates the main inputs and outputs for power, RF and control signals, as well as the interconnection between modules:■program data and audio from the PROG/MIC socket on the UI board to and from the transmitter and receiver modules■audio and signalling from the SYSTEM connector to and from the transmitter and receiver modules■RS-232 data from the serial data connector (IOIOI) to and from the transmitter and receiver modules■fan power and control from the SI board■power distribution from the AC and DC power input connectors to the transmitter and receiver modules, and from the receiver module to the UI board.The circuitry of the individual modules that make up the base station is described in more detail in the following sections.Frequency Bands and Sub-bands The circuitry of the transmitter and receiver modules is similar for all frequency bands and is therefore covered by a single description in this manual. Where the circuitry differs between bands, separate descriptions are provided for each frequency band. For more information on frequency bands, refer to the specifications manual.RS-232 Signals External data communications all occur directly between the connected computer (or other electrical equipment) and the transmitter and receiver modules over the RS-232 serial lines.Fan Signals The power and ground signals for the fans are routed from the SI board to the fans behind the front panel. These signals are electrically isolated from all other system signals to ensure fan noise is not transferred to other sensitive system components.If there is a fault in the fan circuitry, the transmitter module is protected from overheating by its internal foldback circuitry.Speaker Signal Received audio is sent from the receiver module to the UI board. The volume is controlled by the volume potentiometer on the UI board. The audio signal is routed through the UI board to the speaker for monitoring purposes.Power and Ground The SI board provides power to the transmitter and receiver modules. The receiver modules provides power to the UI board.

When describing the operation of the radio the software must be included with the above. This is considered further below.These functional parts are described in detail below.3.1.1 RF HardwareFront End Circuitryand First IF The front-end hardware amplifies and image filters the received RF spectrum, then down-converts the desired channel frequency to a first intermediate frequency IF1 of 45.1MHz (UHF) or 21.4MHz (VHF) where coarse channel filtering is performed. The first LO (local oscillator) signal is obtained from the frequency synthesizer and is injected on the low side of the desired channel frequency for all bands except A4. When receiving the modulation to the frequency synthesizer is muted. The output of the first IF (intermediate frequency) stage is then down-converted using an image-reject mixer to a low IF of 64kHz.Figure 3.2 Receiver high-level block diagramIF:UHF: 45.1 MHzVHF: 21.4 MHzDigitaldown-converterSquelchFrontend1stIFChannelLPFChannelLPFRSSISecond LOUHF: 90.328 MHzVHF: 42.928 MHzFMDemodQuadDemodRXAGCAnalogue-to-digital conversion2nd IF:64 kHzAudiofilteringDe-emphasisOptionalprocessingData and signallingdecodersSidetonesSystem Interfaceor User InterfacePhaselocked toTCXOLPFANTMag.PLLLoopfilterLoopfilterFrequencycontrolTriple-pointEqualisationTCXO:13.000 MHzVCOVCXOCUSTOM-LOGICBLOCKHARDWARE BLOCKDigital-to-analogue conversionKEYNOTES(1) Noise blanker not shownDSPBLOCK
24 Functional Description TB7100 Installation and Operation Manual© Tait Electronics Limited December 2005Quadrature Demodulator The LO for the image-reject mixer (quadrature demodulator) is synthesized and uses the TCXO (temperature-compensated crystal oscillator) as a reference. This ensures good centring of the IF filters and more consistent group-delay performance. The quadrature demodulator device has an internal frequency division of 2 so the second LO operates at 2x(IF1 + 64kHz). The quadrature output from this mixer is fed to a pair of ADCs (analog-to-digital converters) with high dynamic range where it is oversampled at 256kHz and fed to the custom logic device.Automatic Gain Control The AGC (automatic gain control) is used to limit the maximum signal level applied to the image-reject mixer and ADCs in order to meet the requirements for intermodulation and selectivity performance. Hardware gain control is performed by a variable-gain amplifier within the quadrature demodulator device driven by a 10-bit DAC (digital-to-analog converter). Information about the signal level is obtained from the IQ (in-phase and quadrature) data output stream from the ADCs. The control loop is completed within custom logic. The AGC will begin to reduce gain when the combined signal power of the wanted signal and first adjacent channels is greater than about –70dBm. In the presence of a strong adjacent-channel signal it is therefore possible that the AGC may start acting when the wanted signal is well below –70dBm.3.1.2 Digital Baseband ProcessingCustom Logic The remainder of the receiver processing up to demodulation is performed by custom logic. The digitised quadrature signal from the RF hardware is digitally down-converted to a zero IF, and channel filtering is performed at base-band. Different filter shapes are possible to accommodate the various channel spacings and data requirements. These filters provide the bulk of adjacent channel selectivity for narrow-band operation. The filters have linear phase response so that good group-delay performance for data is achieved. The filters also decimate the sample rate down to 48kHz. Custom logic also performs demodulation, which is multiplexed along with AGC and amplitude data, and fed via a single synchronous serial port to the DSP. The stream is demultiplexed and the demodulation data used as an input for further audio processing.Noise Squelch The noise squelch process resides in the DSP. The noise content above and adjacent to the voice band is measured and compared with a preset threshold. When a wanted signal is present, out-of-band noise content is reduced and, if below the preset threshold, is indicated as a valid wanted signal.Received SignalStrength Indication Received signal strength is measured by a process resident in the DSP. This process obtains its input from the demodulator (value of RF signal magnitude) and from the AGC (value of present gain). With these two inputs and a calibration factor, the RF signal strength at the antenna can be accurately calculated.
TB7100 Installation and Operation Manual Functional Description 25© Tait Electronics Limited December 2005Calibration The following items within the receiver path are calibrated in the Factory:■front-end tuning■AGC■noise squelch■RSSI (received signal strength indication)Information on the calibration of these items is given in the on-line help facility of the calibration application.3.1.3 Audio Processing and SignallingAudio Processing Raw demodulated data from the receiver is processed within the DSP. The sample rate at this point is 48kHz with signal bandwidth limited only by the IF filtering. Scaling (dependent on the bandwidth of the RF channel) is then applied to normalise the signal level for the remaining audio processing. The sample rate is decimated to 8kHz and bandpass audio filtering (0.3 to 3kHz) is applied. The base station takes the audio from the receiver mode at Tap R4 by default; this point has no de-emphasis. This tap point can be changed if required, for example, for trunking applications.Data and Signalling Decoders The data and signalling decoders obtain their signals from various points within the audio processing chain. The point used depends on the bandwidth of the decoders and whether de-emphasis is required. Several decoders may be active simultaneously.Side Tones Side tones are summed in at the end of the audio-processing chain. These are tones that provide some form of alert or give the user confidence an action has been performed. The confidence tones may be generated in the receiver. The side-tone level is a fixed proportion (in the order of –10dB) relative to full scale in the receive path. By default, all audible indicators are turned off.CODEC The combined audio and side-tone signal is converted to analog form by a 16-bit DAC with integral anti-alias filtering. This is followed by a programmable-gain amplifier with a range of 45dB in 1.5dB steps. The amplifier performs muting. The DAC is part of the same CODEC device (AD6521).Output to Speakers The output of the CODEC is fed to an audio power amplifier and to the UI board via a buffer amplifier. The output configuration of the audio power amplifier is balanced and drives an internal speaker. The power delivered to the speaker is limited by its impedance. The speaker has 16Ω impedance.
26 Functional Description TB7100 Installation and Operation Manual© Tait Electronics Limited December 20053.2 Transmitter OperationParts of Transmitter Board The main circuit parts of the transmitter board are:■transmitter■frequency synthesizer■CODEC (coder-decoder) and audio circuitry■power supply■interface circuitrySoftware plays a prominent role in the functioning of the board. When describing the operation of the radio the software must be included with the above. This is considered further below.These functional parts are described in detail below.3.2.1 Audio Processing and SignallingMicrophone Input The input to the transmitter path begins at either the SI board or the PROG/MIC connector of the UI board. Only electret-type microphones are supported. The audio input is then applied to tap point T8 on the transmitter board (the tap point is user-selectable).Analog Processingof Microphone SignalThe CODEC (AD6521) performs microphone selection and amplification. The microphone amplifier consists of an amplifier with a fixed gain of 16dB followed by a programmable-gain amplifier with 0dB to 22dB gain. The amplified microphone signal is converted to a digital stream by a 16-bit ADC with integral anti-alias filtering (0.1 to 3.2kHz). The digital stream is transported to the DSP for further audio processing.Figure 3.3 Transmitter high-level block diagramAnalog-to-digital conversionLPFANTPLLLoopfilterLoopfilterFrequencycontrolTriple-pointEqualisationAudiofilteringPre-emphasisOptionalprocessingData and signallingencodersALC MicPGADir.Coup.

TB7100 Installation and Operation Manual Functional Description 27© Tait Electronics Limited December 2005Automatic Level Control The ALC (automatic level control) follows, and is used to effectively increase dynamic range by boosting the gain of the microphone pre-amplifier under quiet conditions and reducing the gain under noisy acoustic conditions. The ALC function resides in the DSP and controls the microphone programmable-gain amplifier in the CODEC. The ALC has a fast-attack (about 10ms) and slow-decay (up to 2s) characteristic. This characteristic ensures that the peak signal level is regulated near full scale to maximise dynamic range.DSP Audio Processing The output of the automatic level control provides the input to the DSP audio-processing chain at a sample rate of 8kHz. Optional processing such as encryption or companding is done first if applicable. Pre-emphasis, if required, is then applied. The pre-emphasised signal is hard limited to prevent over deviation, and filtered to remove high-frequency components. The sample rate is then interpolated up to 48kHz and scaled to be suitable for the frequency synthesizer.Data and Signalling Encoders The data and signalling encoders inject their signals into various points within the audio-processing chain. The injection point depends on the bandwidth of the encoders and whether pre-emphasis is required.3.2.2 Frequency SynthesizerMain Parts of Synthesizer The frequency synthesizer consists of two main parts:■FCL (frequency control loop)■RF PLL (phase-locked loop)The FCL and RF PLL are described briefly below. Note that patents are pending for several aspects of the synthesizer design.Frequency Control Loop The FCL consists of the following:■TCXO■mixer■loop filter■VCXO (voltage-controlled crystal oscillator)■frequency control blockThe FCL provides the reference frequency for the RF PLL. It generates a high-stability reference frequency that can be both modulated and offset in fine resolution steps.
28 Functional Description TB7100 Installation and Operation Manual© Tait Electronics Limited December 2005RF PLL The RF PLL consists of the following:■RF PLL device■loop filter■VCO (voltage-controlled oscillator)■VCO output switchThe RF PLL has fast-locking capability but coarse frequency resolution. The above combination of control loops creates improved frequency generation and acquisition capabilities.Operation ofControl Loop The RF PLL is a conventional integer-N design with frequency resolution of 25kHz. In transmit mode the loop locks to the transmit frequency.Initially, the VCO generates an unregulated frequency in the required range. This is fed to the PLL device (ADF4111) and divided down by a programmed ratio to approximately 25kHz. The reference frequency input from the FCL is also divided down to approximately 25kHz. The phase of the two signals is compared and the error translated into a DC voltage by a programmable charge pump and dual-bandwidth loop filter. This DC signal is used to control the VCO frequency and reduce the initial error. The loop eventually settles to a point that minimises the phase error between divided-down reference and VCO frequencies. The net result is that the loop locks to a programmed multiple of the reference frequency.The FCL generates an output of 13.012±0.004MHz. Initially a VCXO produces a quasi-regulated frequency in the required range. The VCXO output is fed to a mixer where it is mixed with the 13.000MHz TCXO frequency. The mixer, after low-pass filtering to remove unwanted products, produces a nominal frequency of 12kHz. This is converted to digital form and transported to the frequency-control block in custom logic.The frequency-control block compares the mixer output frequency with a reference generated by the digital clock and creates a DC error signal. A programmed offset is also added. This error signal is converted to analog form and used to control the VCXO frequency and reduce the initial error. Once settled, the loop locks to the TCXO frequency with a programmed offset frequency. The FCL output therefore acquires the TCXO’s frequency stability.Modulation The full bandwidth modulation signal is obtained from the DSP in digital form at a sample rate of 48kHz. In traditional dual-point modulation systems the modulation is applied, in analog form, to both the frequency reference and the VCO in the RF PLL, combining to produce a flat modulation response down to DC. Reference modulation is usually applied directly to the TCXO.
TB7100 Installation and Operation Manual Functional Description 29© Tait Electronics Limited December 2005In the system employed in the transmitter board, the frequency reference is generated by the FCL, which itself requires dual-point modulation injection to allow modulation down to DC. With another modulation point required in the RF PLL, this system therefore requires triple-point modulation. The modulation signals applied to the FCL are in digital form, whereas for the RF PLL (VCO) the modulation signal is applied in analog form. The modulation cross-over points occur at approximately 30 and 300Hz as determined by the closed loop bandwidths of the FCL and RF PLL respectively.Frequency Generation The RF PLL has a frequency resolution of 25kHz. Higher resolution cannot be achieved owing to acquisition-time requirements and so for any given frequency the error could be as high as ±12.5kHz. This error is corrected by altering the reference frequency to the RF PLL. The FCL supplies the reference frequency and is able to adjust it up to ±300ppm with better than 0.1ppm resolution (equivalent to better than 50Hz resolution at the RF frequency). Fast Frequency Settling Both the FCL and RF PLL employ frequency-acquisition speed-up techniques to achieve fast frequency settling. The frequency-acquisition process of the FCL and RF PLL is able to occur concurrently with minimal loop interaction owing to the very large difference in frequency step size between the loops.Frequency Acquisitionof RF PLLIn the RF PLL the loop bandwidth is initially set high by increasing the charge pump current and reducing time constants in the loop filter. As a result settling to within 1kHz of the final value occurs in under 4ms. In order to meet noise performance requirements the loop parameters are then switched to reduce the loop bandwidth. There is a small frequency kick as the loop bandwidth is reduced. Total settling time is under 4.5ms.Frequency Acquisitionof FCLThe FCL utilises self-calibration techniques that enable it to rapidly settle close to the final value while the loop is open. The loop is then closed and settling to the final value occurs with an associated reduction in noise. The total settling time is typically less than 4 ms.Calibration The following items are calibrated in the frequency synthesizer:■nominal frequency■KVCO■KVCXO■VCO deviationCalibration of the nominal frequency is achieved by adding a fixed offset to the FCL nominal frequency; the TCXO frequency itself is not adjusted. The items KVCO and KVCXO are the control sensitivities of the RF VCO (in MHz/V) and VCXO (in kHz/V) respectively. The latter has temperature compensation.
30 Functional Description TB7100 Installation and Operation Manual© Tait Electronics Limited December 20053.2.3 RF Power AmplifierRF Power Amplifierand Switching (50W/40W Version)The RF power amplifier and exciter of the 50W/40W radio is a five-stage line-up with approximately 40dB of power gain. The output of the frequency synthesizer is first buffered to reduce kick during power ramping. The buffer output goes to a discrete exciter that produces approximately 300 to 400mW output. This is followed by an LDMOS driver producing up to 8W output that is power-controlled. The final stage consists of two parallel LDMOS devices producing enough power to provide 40 to 50W at the RF connector.RF Power Amplifierand Switching (25W Version)The RF power amplifier of the 25W version is a four-stage line-up with approximately 37dB of power gain. The output of the frequency synthesizer is first buffered to reduce kick during power ramping. The buffer output goes to a broad-band exciter IC that produces approximately 200mW output. This is followed by an LDMOS driver producing up to 2W output that is power-controlled. The final stage consists of two parallel LDMOS devices producing enough power to provide 25W at the RF connector.Output of RFPower Amplifier The output of the RF PA passes through a dual-directional coupler, used for power control and monitoring. Finally, the output is low-pass-filtered to bring harmonic levels within specification.Power Control The steady-state power output of the transmitter is regulated using a hardware control loop. The forward power output from the RF PA is sensed by the directional coupler and fed back to the power control loop. The PA output power is controlled by varying the driver gate bias voltage that has a calibrated maximum limit to prevent overdrive. The power control signal is supplied by a 13-bit DAC driven by custom logic.Ramping Power ramp-up consists of two stages:■bias■power rampingThe timing between these two stages is critical to achieving the correct overall wave shape in order to meet the specification for transient ACP (adjacent channel power). A typical ramping waveform is shown in Figure 3.4.
TB7100 Installation and Operation Manual Functional Description 31© Tait Electronics Limited December 2005Bias Ramp-up The steady-state final-stage bias level is supplied by an 8-bit DAC programmed prior to ramp-up but held to zero by a switch on the DAC output under the control of a TX INHIBIT signal. Bias ramp-up begins upon release by the TX INHIBIT signal with the ramping shape being determined by a low-pass filter. Owing to power leakage through the PA chain, ramping the bias takes the PA output power from less than –20dBm for the 50W/40W version or –10dBm for the 25W version to approximately 25dB below steady-state power.Power Ramp-up The power ramp signal is supplied by a 13-bit DAC that is controlled by custom logic. The ramp is generated using a look-up table in custom logic memory that is played back at the correct rate to the DAC to produce the desired waveform. The ramp-up and ramp-down waveforms are produced by playing back the look-up table in forward and reverse order respectively. For a given power level the look-up table values are scaled by a steady-state power constant so that the ramp waveform shape remains the same for all power levels.Figure 3.4 Typical ramping waveformsPowerrampHigh powerpowerLowPowerTimeBiasrampBiasramp Powerramp

By default, the base station is programmed not to generate any audible indicators.UI Board The UI board is connected to the receiver and transmitter modules via separate 18-way ribbon cables. The internal speaker is connected to the UI board via a cable with a mating connector for easy disconnection. If an internal AC Power supply is fitted, a fan power signal is routed from the fan power board to the fan via the UI board. For more information on the connectors and their signals, refer to “UI Board Connectors” on page 75.Figure 3.6 on page 34 shows a block diagram of the UI board.The UI board does not include a microprocessor. A synchronous bi-directional serial interface provides communication of key status, LCD and LED-indicator data between the transmitter/receiver modules and the UI board. The serial data is converted to or from a parallel form by a number of shift registers for the function keys and indicators. For the LCD, the serial data is fed to a driver IC that converts the serial data to a form suitable for the LCD. The keys are scanned and the LCD and LED indicators updated approximately every 50ms. The TX/RX switch controls what is displayed on the LCD and also whether the transmitter module or the receiver module will be programmed.

46 Installation TB7100 Installation and Operation Manual© Tait Electronics Limited December 20054.6 Recommended ToolsIt 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 base station:■Philips #2 tip screwdriver used to connect the DC power cables to the DC power terminals■Pozidriv PZ3 screwdriver for the M6 screws used to secure the tray to the cabinet in Tait factory-assembled systems■Torx T10 screwdriver for the M3 pan head screws with captured shake-proof washer and flat washer used to secure the modules in the tray■Torx T10 screwdriver for the M3 countersunk screws used to secure the cover and the heatsink channels to the tray■Pozidriv PZ1 screwdriver for the M3 pan head self-tapping screws used to secure the fans.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 base station.4.7 VentilationAlways ensure there is adequate ventilation around the base station. Do not operate at high duty cycles in a sealed cabinet. You must keep the ambient temperature within the specified range, and we strongly recommend you ensure that the cooling airflow is not restricted.Important The cooling fans are mounted behind the front panel. To ensure adequate airflow through the base station, do not operate it for more than a few minutes with the fans discon-nected (e.g. for servicing purposes). 4.7.1 Cabinet and Rack VentilationRefer to Figure 4.2 on page 47.Adequate cooling airflow is critical to the performance of the base station. The cooling airflow for the base station enters through the front panel and exits at the rear of the tray. For optimum thermal performance, the heated air that has passed through a base station must not be allowed to re-enter the air intakes on the front panel. Each base station requires an unobstructed airflow of 18m3/h (11cfm).To allow enough cooling airflow through a cabinet mounted base station we recommend the following:

TB7100 Installation and Operation Manual Preparation for Operation 77© Tait Electronics Limited December 20057 Preparation for Operation7.1 IntroductionThe base station operation can be modified by the use of links and programmable settings.The base station can be configured for operation in the following basic modes of operation:■Line-controlled base: The base station transmit audio and key is derived via the system interface. Audio response is link-selectable.■Talk through repeater (voice): The receiver audio is directly connected to the transmitter and the transmitter is keyed by the receiver gate. Audio response in this mode is software-selectable.■Data repeater: The received data line is connected to the transmit data line. receiver gate and transmitter key signals are not used.■RF modem: Data on the serial interface is connected to the transmitter and the receiver.■TaitNet trunking.7.2 Mode of OperationThis section shows how to set up the base station for various modes of operation.Examples are:■line-controlled base■talk through repeater■RF modem■data repeater■TaitNet trunking.Where applicable, the procedure for setting any of the audio levels or other adjustment points will be described, along with the procedure for measuring a variety of parameters commonly monitored. To verify the operation of the base station it is best to configure it as a line-controlled base first. In this mode of operation the receiver and transmitter modules can be independently tested because all the audio inputs and outputs are accessible via the system interface connector. When the base station has been tested as a line-controlled base, it is then a simple process to change the links to the required mode of operation and perform any additional functional testing required for that mode of operation.
78 Preparation for Operation TB7100 Installation and Operation Manual© Tait Electronics Limited December 20057.3 Line-controlled BaseIn the line-controlled base mode the audio and control signals are routed from the external 25-way D-range connector through the system interface to the receiver and transmitter modules. External equipment is used to control the operation of the base station.7.3.1 Test Equipment RequiredThe following test equipment is used to setup the base station for line-controlled base operation: ■TBA0STU calibration test unit (CTU) which includes the CTU adaptor and CTU cable, or■TBA0ST1 calibration test unit (CTU), TBB0STU-TBB CTU adaptor (220-02068-xx) and CTU cable (219-02888-xx)■PC, programming cables and the TB7100 programming application■digital voltmeter■DC power supply (not necessary with internal AC power supply unit option)■RF test set with:■RF power meter■modulation analyser■RF signal generator■sinad meter■audio distortion meterFigure 7.1 Line-controlled baseSystem InterfaceReceiver TransmitterRF In RF OutRx AudioRx GateTx AudioTx Key

TB7100 Installation and Operation Manual Preparation for Operation 105© Tait Electronics Limited December 20057.8 Programmable FeaturesThe programmable features are applied to the transmitter and receiver modules by using the TB7100 programming application. 7.8.1 Connecting to the PC1. Plug the TPA-SV-006 or T2000-A19 programming lead into the RS-232 serial port on a PC. Note A USB-to-RS-232 adaptor can be used if the PC does not have a built in serial port.2. Connect the TMAA20-04 adaptor cable (RJ12 socket to RJ45 plug) to the RJ12 plug on the TPA-SV-006 or T2000-A19 programming lead.3. Plug the RJ45 plug on the TMAA20-04 adaptor cable into the PROG/MIC connector located on the front panel of the base station. Select whether the TB7100 programming application communicates with the transmitter or receiver module by using the receiver/transmitter programming switch located on the user interface next to the PROG/MIC connector.7.8.2 TB7100 Programming Application The TB7100 programming application allows the configuration parameters of receiver or transmitter to be read out of a module, edited and written back into the module. It is also possible the save the data files, so if a module ever needs to be replaced, the previously saved data file can be programmed into the new module. The model toolbar, indicates whether the data file is for a receiver or transmitter module.Appearance The TB7100 programming application has been optimised for mouse navigation. Most features can be easily enabled and configured using a check box or drop down list and the frequencies for each channel are simply typed into a table.
106 Preparation for Operation TB7100 Installation and Operation Manual© Tait Electronics Limited December 2005Separate Data Files The base station has separate transmitter and receiver modules, which are independently programmed with their required settings. This means that the base station will have two data files, one for the transmitter and one for the receiver.New Data Files The reset to defaults feature in the TB7100 programming application makes it easy to create a new data file. The required module type (receiver or transmitter) is selected by pressing the appropriate button on the radio model toolbar. The reset to defaults feature under the file menu is used to reset all the settings to their default states. This ensures all the mandatory and recommended settings are correct before starting to create a new data file. The customer-specific settings for the current application are entered. reset to defaults only affects the currently active radio model, so the correct radio model must be selected first. If “reset to defaults” is greyed out, then the settings are already in their default states.Existing Data Files An existing data file can be read out of a transmitter or receiver module or loaded from file. The radio model toolbar in the TB7100 programming application will automatically update when a data file is loaded or read out of a module to indicate whether the file is for a receiver or transmitter module. The file can then be edited and saved or programmed back into the module.Note It is possible to read the receiver module and then the transmitter module and have both data files loaded at the same time. The radio model toolbar can then be used to toggle between the two data files.When editing is complete, it is important to ensure the receiver/transmitter programming switch position matches the currently active data file before programming the module.Feature FunctionMenus Located along the top of the screen, these allow the user to perform functions such as opening or saving data files, and reading or programming the modules.Toolbar Located just below the menu bar, the toolbar allows easy access to the most commonly used menu items.Radio Model Toolbar Located just below the toolbar, this indicates whether a newly loaded file type is for a receiver or transmitter module. It also allows the required module type to be selected when a new data file is being created.Forms Tree Located on the left side of the screen, the Forms Tree lists all the forms that are available for editing.Forms Displayed beside the Forms Tree is the Active Form. The TB7100 programming application is made up of several Forms (a page of parameters). All the configuration parameters related to a particular feature are grouped together in one form. Each form is intuitively labelled and easily accessible from a Forms Tree
TB7100 Installation and Operation Manual Preparation for Operation 107© Tait Electronics Limited December 20057.8.3 Mandatory SettingsThe mandatory settings must not be changed from their default states or the base station will not operate correctly. The mandatory settings in the receiver module are not the same as those in the transmitter module. The reset to defaults feature in the TB7100 programming application will ensure all mandatory settings are correct for the selected module type. The mandatory settings are not locked out.

112 Preparation for Operation TB7100 Installation and Operation Manual© Tait Electronics Limited December 2005Transmitter Audio The user-defined settings for the transmitter audio IO are shown below. The cells in grey denote mandatory settings.7.8.5 Recommended SettingsRecommended settings provide system designers with an extra level of flexibility to meet a specific operational requirement. In general, recommended settings should not be changed from the recommended default value. However unlike mandatory settings, the user is permitted to make changes, providing they verify the correct operation of the enabled or modified feature.No guarantee is given that a feature will work if the recommended settings disable the feature, or if a recommended value is changed.Although the individual modules are capable of these features, they cannot be fully supported by the base station because of its two-module configuration. A few examples of features that are not fully supported by the base station are:■selcall ■two tone ■emergency mode ■scanning■encryption (voice inversion).The reset to defaults feature in the TB7100 programming application will ensure all recommended settings are in their recommended default state. Recommended Settings Examples To explain recommended settings more clearly, two Selcall examples are given below. The first example shows that, although Selcall is not a supported feature of the base station, systems designers have much more flexibility to meet a customer’s requirement.Example One A customer has a requirement to remotely turn on external lighting at the base station site.Although Selcall is not a supported feature of the base station, it is likely that enabling Selcall in the receiver could meet this customer’s requirement. With Selcall enabled, a control status could be programmed to turn on a Rx/PTT Type Tap In Tap In Type Tap In Unmute Tap Out Tap Out Type Tap Out UnmuteRx None A-Bypass In On PTT None D-Split On PTTMic PTT None A-Bypass In On PTT None C-Bypass Out On PTTEPTT1 T8 A-Bypass In On PTT None C-Bypass Out On PTTEPTT2 None A-Bypass In On PTT None C-Bypass Out On PTT
TB7100 Installation and Operation Manual Preparation for Operation 113© Tait Electronics Limited December 2005Programmable I/O line. This line could be connected to the lighting control circuit at the site via the system interface connector.Example Two The customer also wants an acknowledgement sent back to confirm that the command to turn on the lights was received.At first the solution would appear to be to enable Selcall auto acknowledgments. However this would not work, because the base station has separate receiver and transmitter modules. The receiver module will decode the selcall and enable the I/O line, but has no method of informing the transmitter to send back an acknowledgment. In fact the receiver module would attempt to transmit the acknowledgment itself, but would be inhibited by other mandatory settings.7.8.6 Function KeysThe base station also has four user-defined function keys on the user interface, and programmable digital input and output lines on the system connector.The tables below list the options that can be assigned to the function keys and the digital input and output lines. The grey cells can be programmed but are not recommended (see “Recommended Settings” on page 112).Function Key OptionsNone Monitor / Squelch OverrideAudible Indicators Volume Network Preset Calls Action Digital Output Line Nuisance DeleteBacklighting Timer Phone Patch Call Request / ReleaseBacklighting Toggle Preset ChannelBacklighting Timer / Toggle Public AddressCall Cleardown Quiet Operation Channel Preset Call Repeater Access Tone Tx Emergency Mode Repeater Talkaround Encryption Reset Monitor Group Scanning Activity Reset Monitor / Call CleardownIgnore Two-Tone Silent Operation Keypress Tones Toggle Single In-Band ToneKeypress Tones Volume Squelch Override Low Power Transmit Scanning / Nuisance DeleteMonitor

It can also generate one CTCSS or DCS tone per channel. The generated tone can be the same as the received tone or can be a different tone. 7.10.1 Enabling Subaudible SignallingTransmitter Module 1. Read the data file out of the transmitter module. Figure 7.11 System interface link positionsJ206RV200J207W401RV401W402J401W302W300W301RV400 J222
116 Preparation for Operation TB7100 Installation and Operation Manual© Tait Electronics Limited December 20052. Open the channels form and select the required tone in the Tx Sig column.3. Open the Networks > Basic Settings > Subaudible Signalling tab and configure the subaudible signalling settings (the defaults are suitable for most applications).4. Program the new settings into the transmitter.Receiver Module 1. Read the data file out of the receiver module. 2. Open the channels table and select the required tone in the Rx Sig column.3. Open the Networks > Basic Settings > Subaudible Signalling tab and configure the subaudible signalling settings (the defaults are suitable for most applications).4. The Rx tap out point in the receiver (Programmable I/O audio tab) must be changed to R5. This means that a incoming tone/code is filtered out by the receiver. 5. Program the new settings into the receiver.7.10.2 Testing Subaudible SignallingBefore carrying out these tests, the base station must be configured as a line-controlled base. It must also be connected to the test equipment as described in “Test Equipment Setup” on page 79.Tx Subaudible Signalling Deviation 1. Set up the test set to measure the modulation level and frequency.2. Ensure the test set audio output is turned off, or disconnect the CTU audio input from the test set.3. Activate the Tx Key switch on the CTU.4. Verify that the measured frequency and deviation of the CTCSS match the programmed settings.Note If the measured value does not agree with the programmed set-tings, the transmitter module is either faulty or needs recalibrating.Rx Subaudible Signalling Decode 1. Connect the balanced audio output from the CTU to the audio input port on the test set.2. Set up the test set to measure the audio level and distortion.3. Set the RF signal generator to the correct RF frequency, modulated with a 1kHz audio tone at 60% of full system deviation.
TB7100 Installation and Operation Manual Preparation for Operation 117© Tait Electronics Limited December 20054. Set the RF output level to -70dBm.5. Verify that the busy LED on the front panel of the base station turns on but the Rx gate LED on the CTU does not turn on, and no audio output is detected from the balanced line output.6. Modulate the carrier with the required subaudible signalling.7. Verify that the Rx gate LED on the CTU turns on, and that the 1kHz audio tone is detected by the test set, and that the measured distortion level is within the receiver specifications.8. Turn off the subaudible signal and check that the audio output mutes again.Note If high distortion is measured, it is likely that the subaudible signal is not being filtered out. Verify that the receiver is programmed with the correct audio tap out point.7.10.3 Multiple Subaudible TonesThe base station cannot decode multiple subaudible tones on a single channel. This can be overcome by two methods:Method 1 1. Third-party equipment is available that can be connected to the base station to perform the decoding and regeneration of multiple tones.2. The base station repeater can be configured to simply pass through any subaudible tone. Method 2 1. The receiver must not be programmed with any subaudible tones in the channel table.2. The Rx tap out point in the receiver (Programmable I/O audio tab) must be left as the default value of R4. This means that a incoming tone/code is not filtered out by the receiver. 3. The transmitter must be programmed not to generate any subaudible tones. 4. The Tx Tap In point in the transmitter (Programmable I/O audio tab) must be left as the default value of T8. This means that a incoming tone/code is not filtered out by the transmitter and will be re-transmitted.Potential Problems 1. The Rx gate may close before end of reverse tone burst (RTB). This means the re-transmitted RTB may be shorter than incoming RTB. A Tx tail (soft off) should be added to overcome this. 2. There is no security for repeaters, as any on-frequency transmission will be repeated, even if it has no subaudible tone.
118 Preparation for Operation TB7100 Installation and Operation Manual© Tait Electronics Limited December 20057.11 Soft Off (Tx Tail Time)If subaudible signalling is used, a Tx tail time can be added using the Networks > Basic Settings > Subaudible Signalling tab. A lead out delay can be entered in the appropriate field. 7.11.1 Link Settings Remove the cover as detailed in “Removing the Base Station and Opening the Tray” on page 54 and set the jumper positions on the system interface to match the table below. Replace the cover as detailed in “Final Reassembly” on page 63. Refer to Figure 7.11 on page 115 for the link location.Note When link W302 is fitted, resistor R300 must be fitted.However, if subaudible signalling is not used, adding a lead out delay will have no effect. If soft off operation is still required, a Tx tail time can be created by:1. Linking AUX_GPIO6 and AUX_GPIO7 of the transmitter with link W302 on the system interface as above.2. Adding the following to the default Tx configuration:■AUX_GPIO6 >Direction = input■AUX_GPIO6 >Action = External PTT 2■AUX_GPIO6 >Active = High■AUX_GPIO6 >Debounce = 200 (or smaller if desired)■External PTT (2) > Transmission Type = None.Note A maximum of 200 ms tail time can be achieved using this method.7.12 Tone On Idle (TOI)The tone on idle provides a tone that can be used for indicating when the base station is not transmitting or receiving. The links to enable or disable the tone on idle are shown in the table below. Both links must be in for the TOI to work.Table 7.9 Soft off—link settingsLINK Name Pins Position Function CommentsW302 TX_Key to TX_GPIO6 link 2 FittedNot fitted When fitted this allows two external PTT to control the transmitter; used for soft off modeDefault is fitted

The potentiometer and test point to adjust the temperature threshold can be found on the system interface module. Refer to Figure 7.11 on page 115 for the location.When adjusting the temperature threshold the fans must be off. The temperature threshold to voltage relationship is shown in Figure 7.13 on page 121.Important When using THSD and the user interface PTT, the fan set-ting should be temperature controlled or always on. This is because the user interface PTT line does not toggle the TX-key line on the system interface and the THSD is only on for short burst of time never allowing the fan time to spin up.Designator FunctionRV200 temperature threshold adjustJ222 test point for temperature thresholdFigure 7.13 temperature threshold to voltage relationship0.92 0.98 1.04 1.10 1.16 1.22 1.28 1.34 1.40 1.46 1.520102030405060708090VoltageTemperature50688610412214015817619432FahrenheitCelsius

124 Preparation for Operation TB7100 Installation and Operation Manual© Tait Electronics Limited December 20057.17 Carrier Wave Identification (CWID)CWID is a morse identification feature that can be setup using the TB7100 programming application.7.17.1 Station IDCan contain a preprogrammed station ID of up to 16 characters in length. The user may wish to prefix the letters DE before the message, meaning “from”.7.17.2 Station ID 2/MessageCan contain a second preprogrammed station ID or a message of up to 130 characters.7.17.3 Tone FrequencyThe Morse tone frequency is programmable from 1Hz to 3000Hz in one cycle increments. FCC rules state that the frequency shall be 800Hz to 1200Hz.7.17.4 ID Repeat TimeA programmable repeat time from 1 to 99 minutes. This allows the user to program how often the ID or message is sent. Setting the output control to “After PTT” will cause the ID message to be sent following the last activation of the COR/COS/CTCSS, Inhibit or PTT inputs, provided the time is met that is programmed in this register.7.17.5 Speed (Words per Minute)The speed is programmable from 1 to 99 words per minute (WPM).7.17.6 Wait Period after Loss of COR/COS/CTCSS Input Before IDingThis register allows from 1 to 99 seconds of delay before the Morse ID will transmit after COR/COS/CTCSS loss assuming the repeat interval in ID Repeat Time has expired.7.17.7 Transmit Key-Up DelayProgrammable key-up delay from 0.0 to 9.9 seconds. This allows for a front porch delay time before the ID or message is sent. This gives receiving units
TB7100 Installation and Operation Manual Preparation for Operation 125© Tait Electronics Limited December 2005with CTCSS decoders time to un-squelch before any Morse code is transmitted.7.17.8 Transmit Time Out TimeIf programmed to 0 this function is off. Programming from 1 to 999 seconds will set the repeater to drop out after the number of seconds programmed in this register. The time out timer is designed to limit conversation length.7.17.9 Transmit PTT Drop Out TimeThis register programs how many seconds the repeater’s transmitter will stay keyed after loss of COR/COS/CTCSS input. Normally this is programmed for 2 to 7 seconds. After PTT In is detected, the ID-1 will turn on its PTT out, as long as the PTT In remains active. After loss of the PTT In, the PTT out will remain active for the programmed period of time before dropping, thus allowing another unit to answer before the repeater drops. The ID-1 must be installed in series with the PTT line (i.e. ID-1 installed at break in station PTT line) for this function to operate.7.17.10 Output ControlSetting the output Control to “After PTT” will cause the ID message to be sent following the last activation of the COR/COS/CTCSS, inhibit or PTT inputs, provided the time is met that is programmed in the register ID repeat time. setting the output control to “continuous” will cause the ID or message to be sent at the expiration of a period equal to the delay time. For example, if register ID repeat time is programmed as 10, the ID or message will be sent every 10 minutes. This will occur during a conversation if one is in progress when the timer goes off.

TB7100 Installation and Operation Manual Glossary 131© Tait Electronics Limited December 2005city squelch When a radio’s noise mute threshold is programmed for city squelch, the radio is less sensitive to interference than if programmed for country squelch and so stronger signals are required for the radio’s speaker to unmute.City squelch is also known as local squelch.CODEC An IC which combines analog-to-digital conversion (coding) and digital-to-analog conversion (decoding).configuration file A configuration file consists of all the configuration settings needed for a base station, stored as a file in the configurations folder. Configuration files have the extension *.t7p. The TB7100 uses two files, one for the receiver and one for the transmitter.country squelch When a radio’s squelch threshold is programmed for country squelch, the radio is more sensitive than if programmed for city squelch and so the radio’s speaker unmutes more readily. When programmed for country squelch, the radio can be used in areas where the signal may be weak and where maximum range is desirable.Country squelch is also known as distant squelch.CTCSS CTCSS (continuous tone controlled squelch system), also known as PL (private line), is a type of signalling that uses subaudible tones to segregate groups of users.CTCSS/DCS filter The CTCSS/DCS filter removes any CTCSS or DCS tones that may be present on the received audio. The filter limits the range of frequencies the radio passes from the incoming signal to the speaker and so in some situations affects signal quality. Filtering can be automatically switched off for channels that do not have CTCSS or DCS.CTU A Calibration Test Unit (CTU) is a device used to assist in making testing and calibration of the TB7100 easier.CWID CWID (Continuous Wave IDentification) is a method of automatically identifying the base station using a Morse code.DDAC Digital-to-Analog Converter. A device for converting a digital signal to an analog signal that represents the same information.data call A data call is a call or part of a call between two radio units that carries data rather than speech communications. A data call can be a status message, short data message or non-prescribed data (NPD) call.DCS DCS (digital coded squelch), also known as DPL (digital private line), is a type of subaudible signalling used for segregating groups of users. DCS codes are identified by a three-digit octal number, which forms part of the
132 Glossary TB7100 Installation and Operation Manual© Tait Electronics Limited December 2005continuously repeating code word. When assigning DCS signalling for a channel, you specify the three-digit code.de-emphasis De-emphasis is a filtering process in the receiver that attenuates higher frequency audio. It restores pre-emphasised audio to its original relative proportions. digital signal processor The device in a radio that analyses and processes signals in the digital domain. Also known as DSP.Duplexer A duplexer is a device for connecting one antenna to a transmitter and receiver at the same time.duty cycle Duty cycle is used in relation to the transmitter. It is the proportion of time (expressed as a percentage) during which the transmitter is keyed. The transmitter can be operated continuously. Eeconomy cycling Economy cycling is the switching between states that occurs when economy mode is active and after there is no valid activity on a channel for a preprogrammed time (the economy mode timer). Economy cycling consists of two states, the receive state and the standby state. The amount of time the radio spends in each state is determined by the economy duty cycle.economy duty cycle The economy duty cycle is the amount of time the radio spends in the receive and standby states during economy cycling.economy mode Economy mode reduces the radio’s power consumption when it is idle. When economy mode is active, and there has been no valid activity on a channel for the duration of the economy mode timer, the radio begins economy cycling.economy mode timer The economy mode timer sets the time between when valid activity was last detected on a channel and the start of economy cycling.

TB7100 Installation and Operation Manual Glossary 133© Tait Electronics Limited December 2005FFFSK FFSK (fast frequency shift keying). In Trunking applications this is the method by which code words are sent over the control channel. In 1200 baud FFSK, a 1200 Hz tone represents a zero and an 1800 Hz tone represents a one.frequency band The range of frequencies that the equipment is capable of operating on.front panel The part of the chassis that has the user interface on it.Full Duplex Full duplex is the action of receiving and transmitting at the same time.function key A function key is a key on a radio or radio accessory that can have functions assigned to it. Ggating Gating is the process of opening and closing the receiver audio path. When a valid signal is received, the receiver audio path opens. GPIO General Purpose Input Output (GPIO) lines are used on the TB7100 to configure it for different modes. Hhysteresis Hysteresis is the difference between the upper and lower trigger points. For example, the receiver gate opens when the upper trigger point is reached, but will not close until the level falls to the lower trigger point. An adequate hysteresis prevents the receiver gate from repeatedly opening and closing when the level is about that of the trigger point. Iinactive Digital outputs are inactive if the base station is doing nothing to them. They are floating, open collector outputs. Digital inputs are inactive when they are open circuit. indicator Indicators provide feedback to the radio user on how the current operation is proceeding and on the operating state of the radio. For example, keypress confidence tones are the tones heard when a keypad key or a function key is pressed and tell the user that an action is permitted. Tait radios use combinations of audible indicators and visual indicators.inhibit Prevents the radio state changing.
134 Glossary TB7100 Installation and Operation Manual© Tait Electronics Limited December 2005isolator An isolator is a passive two-port device which transmits power in one direction, and absorbs power in the other direction. It is used in a PA to prevent damage to the RF circuitry from high reverse power, and reduces the generation of spurious product due to the ingress of signals from other transmitters.Kkerchunking Kerchunking is transmitting for a second or less without saying anything in order to test the base station. This results in a ‘kerchunk’ sound.keypress confidence tone A keypress confidence tone is a type of audible indicators given each time the user presses a key to confirm that the action selected is valid.LLCD A Liquid Crystal Display (LCD) is used on the TB7100 user interface to display channel number.line-controlled base station A TB7100 is a line-controlled base station when it receives audio (sending it out via its systems interface), transmits audio received over its systems interface, and its transmitter is keyed via the Tx Key line.local squelch See city squelch.MMandatory Settings The mandatory settings are settings in the programming application that must not be changed from their default states or the TB7100 will not operate correctly. The Mandatory Settings in the receiver module are not the same as those in the transmitter module.mute A mute controls the circumstances under which a received signal is passed to the radio’s audio output. When a mute is active, the radio’s speaker audio path opens under certain conditions, determined by the type of signalling operating on a channel and the noise mute threshold.Nnoise mute The noise mute feature ensures that the radio’s speaker only unmutes when an intelligible signal is received. A signal is considered intelligible when it is strong enough to exceed a predetermined noise mute threshold.noise mute threshold The noise mute threshold is the level the signal must reach before it is regarded as intelligible and the radio’s mute is opened.

The programming application can read files from the base station or load new files onto the base station.programming database The programming database is the information that is altered using the radio programming application. For trunked radios, each programming database consists of separate network, fleet and radio information.programming mode The mode of operation of the radio in which computer equipment can read from and write to the radio database.Qquiet operation When quiet operation is active, all audible indicators except incoming call alerts, sidetones and warning tones are disabled. Contrast with silent operation.quiet state The quiet state is the state the radio is in when monitor is inactive the radio user does not have to listen to traffic that is not intended for them.RRecommended Settings Recommended settings are settings in the programming application that should not be changed from the recommended default value, but unlike mandatory settings, the user is permitted to make changes; providing they verify the correct operation of the enabled or modified feature. No guarantee is given that a feature will work if the recommended settings disable the feature or if a recommended value is changed.
136 Glossary TB7100 Installation and Operation Manual© Tait Electronics Limited December 2005repeater A repeater receives a radio signal and re-transmits it. Use of a repeater increases the coverage area of a two-way radio system and ensures more reliable performance in areas where signals are reflected or attenuated by buildings or terrain.In a repeater-based system, the radio’s transmit frequency is the frequency the repeater is listening on, and the radio’s receive frequency is the frequency the repeater re-broadcasts signals on.receive (Rx) frequency The receive frequency is the frequency that a radio is currently tuned to.reverse tone burst Reverse tone bursts (RTB) can be used with CTCSS. When reverse tone bursts are enabled, the phase of the generated tones is reversed for a number of cycles just before transmission ceases. If the receiver is configured for reverse tone burst, it responds by closing its gate faster than if the RTB were not transmitted.RF RF stands for radio frequency and refers to the part of the electromagnetic spectrum used to transmit radio and television signals.RSSI RSSI (Received Signal Strength Indicator) feature that indicates the strength of the received signal. Rx Rx is an abbreviation for receive or receiver.Ssensitivity The sensitivity of a radio receiver is the minimum input signal strength required to provide a useable output.SINAD SINAD (Signal plus Noise and Distortion) is a measure of signal quality. It is the ratio of (signal + noise + distortion) to (noise + distortion). A SINAD of 12dB corresponds to a signal to noise voltage ratio of 4:1.subaudible signalling Subaudible signalling is signalling that is at the bottom end of the range of audible frequencies. The base station supports CTCSS and DCS subaudible signalling. subtone A subtone (subaudible signalling tone) is a CTCSS tone or a DCS code. switching range The switching range is the range of frequencies that the equipment is tuned to operate on.system interface The system interface is the set of inputs to and outputs from the base station (excluding RF), provided by a module inside the tray.

It is typically used for short connections, for example, between a base station and a repeater on the same site. The system interface identifies the wires of unbalanced lines with Rx audio output, Tx audio input, and Ground.User Defined Settings The User Defined Settings are settings in the programming application that are specific to the customers application. These are the only settings that need to be changed when configuring a TB7100 for operation.user interface The user interface panel is an area at the front of the base station with buttons, LEDs and other controls that let you interact with the base station.Vvalid signal A valid signal is a signal that the receiver responds to by opening the receiver gate. A signal is valid for example when it is stronger than a minimum level and when it has the specified subtone.visual indicator The term “visual indicator” refers to a visual cue the radio gives to provide feedback to the user. Visual indicators are used in combination with audible indicators. Visual indicators include LEDs and LCD display text.VSWR Voltage Standing Wave Ratio (VSWR) is the ratio of the maximum peak voltage anywhere on the line to the minimum value anywhere on the line. A perfectly matched line has a VSWR of 1:1. A high ratio indicates that the antenna subsystem is poorly matched.WWatchdog A watchdog circuit checks that the system is still responding. If the system does not respond (because the firmware has locked up), the circuit resets the system.
