Parts List 1.1 INTRODUCTION The KLT radio, which is also referred to as FMR (Fleet Management Radio), is designed for alarm purposes, vehicle location (and tracking) and fleet management. In contrast to “normal” mobile units KLT is not intended for speech processing. Data is transmitted by analogue tone FM modulation. Its compact size makes it ideal for the above applications. The unit may be operated on either standard MPT1327 system or on a Kavicomm proprietary system. 1.2 SPECIFICATIONS General Power Supply Operating Voltage : 10,8 to 15,6V DC. Antenna Impedance : 50Ω, unbalanced.

INSTALLATION 2.1 General Radio placement in a vehicle is not critical to its performance. Because of its small size the radio could practically be installed almost anywhere. Do not install the unit where ambient temperatures could rise above +60°C. Choose a place where the main power cable will be as short as possible. 2.2 Power Source The radio operates from a 13.6V DC (6 Amp) source such as a standard automotive “12v” negative Gnd electrical system. In case a vehicle uses “24V” system it is recommended to use a proper DC to DC converter preferably a linear type (if possible) in order to avoid radio interference. The installer is advised to make sure that the vehicle’s battery is “healthy” and that it is not lower than 10,8V DC. A low battery or defective regulator can severely impair the unit’s operation. A power cable is supplied with the radio. The red wire must always be connected to the (+) terminal of the battery and the black to the (-) terminal. CAUTION Do not ever apply more than 16V to the radio. Check the voltage source before connecting the power leads to it. Do not connect the power leads to the cigarette lighter socket or to any other points where high spike voltages might develop. Do not install the unit in a positive GND vehicle. 2.3 Antenna The antenna and its coaxial cable are supplied by Kavicomm. The installer may install other antennae provided they are of equivalent quality or better. Bear in mind that the radio is designed to operate with a 50Ω antenna. 3. FEATURES AND OPERATING INSTRUCTIONS 3.1 Features The unit is a multipurpose one. The main purpose is raising alarm signals once activated by input at the Micro-Controller connector. The alarm data is transmitted using FFSK signals, which are decoded at the central control room or other similar means. In addition the unit could be used as a radio link repeating signals which are received by its receiver. Both of the above-described functions utilize either a standard MPT1327 network or Kavicomm’s proprietary network. The receiver is equipped with Relative Signal Strength Indication (RSSI) in order to facilitate locking on strongest (RF) signal available on the network. 3.2 Operating Instructions Once the radio is installed as per installation instructions (see section 2) the radio is turned on (no switch for turning the radio on is available). If a RF signal is available on the air to which the radio is programmed to receive, he unit locks on. The RSSI indication led will flash periodically. The more times the led flashes the stronger signal is being received. 5 flashes in a row indicate that the signal strength is stronger than – 80dMm. No more than 5 flashes are available even if the signal is very strong. When the led flashes only once the signal strength is around – 110dBm. If no signal is available the led flashes at a very low rate. As the unit has no other indications and/or knobs to operate the operation becomes very simplified. 4. THEORY OF OPERATION 4.1 Receiver The receiver is double heterodyne type having the 1 st I.F at 45MHz and 2 nd I.F at 455KHz. The receiver outputs two signals: (a) A DC voltage level which is relative to received signal strength and (b) FFSK signal which is composed of two tones 1200 and 1800Hz. Both of the above signals are fed to the Micro-controller circuitry for analysis and detection. The received signal, which comes from the antenna connector and flows via the Tx L.P.F. (harmonic trap), is applied via C 95 , C 97 , C 98 , C 100 , C 101 and C 103 to the base of the RF Front End Amplifier Q 25 . C 96 and L 25 form the first Front-End filter. So do the other components which follow with a similar arrangement. This amplifier provides some 15-dB ga…

Receiver Block Diagram Receiver Block Diagram Description The received signal which comes via the L.P.F. in the Transmitter (Tx) goes via the Front End (F/E) Band pass filter to the RF F/E Amplifier. The total gain of the F/E filter and the F/E Amplifier is in the order of 12dB. The Amplifier’s signal is fed to the Mixer which is also fed the L.O. signal, the Mixer provides some 15dB gain as well as the difference between the incoming signal and the L.O. signal which is 45MHz. The x-tal Filter and IF amplifier filter the 45MHz signal and feed it to the IF chip which together with the quadrature tank circuit demodulate (recover) the audio tone signal. The difference of 455KHz is achieved by mixing inside the IF chip between the 45MHz incoming signal and the 45,455MHz x-tal oscillator which is also part of the IF chip. The demodulated tone signals pass through a Tchebeshef L.P.F circuit and is fed into a Modem circuit which is part of the Micro-controller. The I.F. chip produces also an RSSI (DC) signal which is also fed to the Micro-controller. received signal Front End Band Pass Filter F/E AMP Mixer L.O. signal (45MHz below Rx-d signal) X-tal Filter and IF Amp 45,455MHz I.F.

(2,5KHz) Demodulated signal to Modem in Micro-controller ~ ~ ~ Transmitter Block Diagram Transmitter Block Diagram Description The transmitter consists of 3 RF amplifiers. The 1 st RF Amplifier amplifies the +6dBm incoming drive signal to a level of approx. +16dBm. The amplified signal passes through the RF Attenuator diode and feeds the RF Module (type M67749HR). This in turn produces a level of 5 to 7W of RF output. This signal is fed to the RF Power Amplifier via a matching line (Micro-strip). The RF power amplifier, which is capable of transmitting up to 20W, amplifies the signal to the desired level. As the radio is specified as a 15watts device, it is set so at the factory by the set ref. voltage/level potentiometer (top right-hand side of diagram). The current at the 50Ω line is sampled (sensed) by the RF sampling diode which produces a DC voltage relative to the O/P power this DC is compared to the Set Ref. Voltage by the ALC Opamp which in turn biases the RF attenuator diode, thus setting the O/P to 15W.

The radio could work in one of the following modes: a) On a fixed channel. b) On a group of channels, choosing the strongest one (by using its RSSI facility) and locking on it. Depending on the way it is programmed the radio can operate on either mode a or b but not both. The Micro-controller may be connected to an external device to receive a command or to deliver a command to that external device. The commands are DC signals of either high (5V) or low (0V) voltages. The same I/O port serves also for programming the KLT. The Freq. Synthesizer receives a command from the Micro-Controller as to what frequencies (for L.O. Injection and Tx Drive) it should produce. The Micro-Controller circuitry also produces the Modulating (tone) signal which is responsible for the modulation of the Tx VCO. This modulation is of Analogue Frequency type. The modulating signal can be either 1200Hz tone or 1800Hz. No other tone frequency is used. The frequency deviation is always fixed at 1,5KHz ± 1dB. In addition the Micro-controller receives a demodulated tone of the above freq. (i.e. 1200Hz or 1800Hz) and outputs a command at the I/O port. The transmitter is driven by the L.O. Tx drive signal which is of the order of 6-8dBm. The Tx produces a signal of 15W maximum, this signal passes through the low pass filter (LPF) which acts as a harmonic suppressor (trap). Thus delivering a “clean” signal with harmonic content of less than –70dBC. The receiver signal passes through the Tx LPF and arrives at the its Front End. The receiver outputs the demodulated signal which goes to the Micro-Controller. Frequency Synthesiser Receiver LPF Antenna 0dB Micro-Controller Transmitter I/O to/from External Device L.O. Injec.

The Micro-Processor IC receives the commands as to when to transmit an alarm signal and to what frequency the synthesiser must be locked on. The Processor can also raise an alarm DC level at the I/O port depending on the mode that the programming was done for. The Micro-Processor also receives the RSSI (DC) signal via an A/D device (U3) this allows it to choose a better off-the-air signal if available. The FFSK Tone Modem outputs the tones-modulating signal-to directly (analog) modulate the Tx VCO in Synthesiser. In order to save energy the radio can be “put to sleep” by using the Radio Disable (DC) command which is sent to IC U23 via the LATCH U5 in the Micro-Controller part of the KLT.

5. MAINTENANCE 5.1 RF Circuitry main Test Points and Alignment Locations. The RF circuitry contains many test points in order to facilitate troubleshooting and repair of circuitry when needed. The following Voltage Chart gives the main test points and the expected limits of levels. Also the conditions under which the measurements should take place are listed. Voltage Chart for Main Test Points – RF Circuitry Test Point Mode/Remarks Level TP33 Tx and Rx depending on VCO setting* 3V - 7VDC TP29 Tx 1,8V – 2,6VDC TP28 Rx 1,8V – 2,6VDC TP25 Tx 1,2V – 1,7V DC TP22 Tx +6dBm - +10dBm TP20 Tx 4,5V – 5,1VDC TP21 Rx +2dBm - +5dBm TP30 Tx and Rx 150mvrms – 270mvrms TP45 Tx (Without drive at C145) 1,50V – 1,70V DC TP46 Tx (Without drive at C145) 3,9V – 4,5VDC TP48 Tx (Without drive at C145) 1,5V – 1,8VDC TP47 Rx 5,6V – 6,2VDC TP37 Rx 3,7V – 4,1VDC TP41 Rx 4,8V – 5,2VDC TP40 Rx (depends on signal strength received 1,5V – 5,0VDC either at antenna terminal or at TP35) * VCO setting (voltage at TP33) depends on the band of frequencies that radio has to cover. The lower the frequency the lower the voltage. If only a few channels close in frequency are used adjust VCO coils for voltage to be approx. 5V. 5.2 Controller Circuitry Test Points Various Test Points are provided in order to ensure the correct function of the Controller. The following chart lists them: Test Point Mode/Remarks Level TP16 Rx. Checks the demodulated received 650mV p-p FFSK level for correct decoding under received signal (1,5KHz deviation) TP13 Rx. No RF present at antenna terminal 4,1V – 4,9V DC TP15 Tx. FFSK output to modulate the VCO 2V – 2,5V p-p TP7 Rx. Checks the sequence of “0” and “1” 0 – 5V p-p This sequence depends on the DC level received from the RSSI circuitry (U25 pin 1). TP1 Rx. Checks the analogue DC voltage to 1,5V – 5,0V DC the A/D converter (U2). This voltage depends on received signal strength. 5.3 Alignment Procedures 5.3.1 Synthesiser Alignment Procedure In the Synthesiser circuitry there are only 4 adjust / tuning points: R 136 , U 21 , L 14 and L 12 . In order to align the Synthesiser, power the radio with its test jig and program the radio to the desired channels (frequencies). a) Adjusting the Lock-Line voltage at TP 32 . The lowest limit for the Lock-Line voltage is 3,0VDC and the highest 7,0VDC. The lower the frequency the lower the voltage. If there are desired frequencies that are spread over a few MHz. choose first the lowest one and adjust L 12 so that the voltage at TP 32 is 3,0VDC. Switch to the other channels and make sure that the voltage does not exceed 7,0VDC. Note: In case there is only one channel or a group of channels close in frequency adjust the voltage approx. 5,0VDC. Connect a 50Ω dummy load to antenna terminal and switch to Tx mode using the P.T.T. switch and repeat the above alignment procedure. This time adjust L 14 . b) Adjusting the RF Frequency Error. Connect a 50Ω dummy load to the attenuator / antenna terminal. Connect the output of the attenuator to a calibrated frequency counter. Switch the radio to Tx mode and measure the frequency. Adjust the adjustment point on U 21 to get the correct frequency i.e. zero error. c) Adjust the Modulation (Frequency Deviation). Repeat the connection procedure as in b) above but instead of measuring frequency measure FM modulation. Switch the test jig so that the radio produces modulation. Measure at the upper part of R 135 that there is approximately 2V p-p of FFSK signal. Adjust R 136 to get 1,5KHz deviation ± 0,5dB. Repeat the modulation measurement at another desired RF channel (frequency) and make sure that it is again 1,5KHz ±0,5dB. 5.3.2 Receiver Alignment Procedure Connect the radio as described in 5.2.1 above. With the radio on Rx mode monitor the SINAD at TP 38 while injecting approx. –70dBm RF signal modulated by 1,0KHz tone, 1,5KHz deviation. Adjust L 30 , L 31 and L 33 for best SINAD. Reduce received signal gradually and keep monitoring the SINAD. Tune Front-End coils for maximum SINAD when signal is –110dBm. If necessary readjust coils L 30 , L 31 and L 29 . Reduce further the incoming signal until the SINAD meter reads 12dB the incoming level should be between –113 and –116dBm. Switch to another desired frequency and make sure that you get again 12dB SINAD or better for –113dBm of incoming RF signal. Adjust potentiometer R 162 to get approx. 70mV rms at TP 138 . Inject at antenna terminal –100dBm and adjust R 171 to get 2,5VDC at TP 40 . 5.3.3. Transmitter Alignment Procedure The transmitter is a wideband type; as such it does not have any tuning trimmer components. The RF output power is determined by potentiometer R 215 . In order to set the output power, switch the radio into Tx mode and turn R 215 until the power meter connected to the antenna terminal displays the desired power at the frequency of interest.
