Fleetwood Group Inc. FCC ID: FBR-TX216SYN-2 Operational Description Page 1 of 3 File Name: TXDESC.DOC Date: 11/15/99 Reply® Transmitter Model TX216SYN FCC ID: FBR-TX216SYN-2 Operational Description Introduction The Fleetwood Model TX216SYN is a low power transmitter designed for operating in the frequency range from 216 to 220 MHz to be type accepted for operation under Part 90.259. The transmitter is manufactured as a printed circuit module approximately 2 inches by 3 9/16 inches using surface mount components. This module replaces an earlier design originally approved in 1989 (FCC ID: FBR-5FKRSPTX-1) which was enclosed in a larger case, crystal controlled on a single frequency, and used more costly through hole technology for manufacture. The new design utilizes surface mount technology and state of the art synthesizer design providing cost reduction in addition to allowing operation on frequencies in the 216-220 MHz range. General System Description The Fleetwood Model TX216SYN transmitter is used as a part of a base system which communicates with a number of response keypads (approved under separate applications) to allow feedback from participants in a meeting or classroom situation to be collected and displayed on a personal computer running a controlling application. The base unit composes and sends via the Model TX216SYN transmitter an addressing signal to the keypads which determines when they will transmit their entry back to the base unit. The keypad entries are typically one of ten keys on a membrane switch panel on the keypad. Transmitter Theory of Operation The Model TX216SYN transmitter is designed using a National LMX2313 Frequency Synthesizer IC. A crystal controlled oscillator Q4, Y2 and associated components serves as its frequency reference at 10.2 MHz. The precise frequency is adjusted by trimmer capacitor C37. The reference frequency is divided by 1020 in the LMX1601 to generate an internal reference of 10 KHz. The programmable dividers in the LMX1601 are set by a serial bit stream sent from the Atmel microcontroller on power up to set the synthesizer to the appropriate values for the selected channel. The Atmel microcontroller receives the channel assignment by reading the settings of a 4 position dip switch on the interface board. The only function of the Atmel microcontroller is to program up the LMX1601 frequency synthesizer. The VCO consists of Q1, L2, and D2 and associated components. A portion of the VCO output is provided to the RF input of the LMX1601 synthesizer. Inside the LMX1601 the divided down frequency of the VCO is compared with the 10.2 MHz derived reference frequency and the voltage on the output of the phase detector reflects the relationship between these two signals. The phase detector voltage is conditioned by a low pass filter consisting of C3, C4 and R3 to provide the controlling signal for the VCO. The VCO is thereby locked to one of the channels shown in the frequency table for operation within the 216-220 MHz range. Fleetwood Group Inc. FCC ID: FBR-TX216SYN-2 Operational Description Page 2 of 3 File Name: TXDESC.DOC Date: 11/15/99 The output of the VCO is buffered by transistor Q3 which is then fed to amplifier U2 to increase the power level to the 50 mw level. Suppression of harmonics and spurious radiation is accomplished by a bandpass filter consisting of components L7-L10 and C2, C22, C25, C28, and C44. The output is fed to a BNC connector for attachment of an external antenna, typically a quarter wavelength whip. Frequency modulation is accomplished by applying the rail to rail (0 to 5V) signal TXDATA through an appropriate network of components to the VCO resulting in FSK modulation of the VCO. Transmitter Modulation Characteristics The Model TX216SYN transmitter operates with Frequency Shift Keyed (FSK) binary data with +/- 10 KHz nominal deviation. It is modulated from a signal provided by a crystal controlled microprocessor part of Model CRS920, separately compliance tested for its digital circuits. This signal has a 0 to 5 volt range and therefore cannot be driven above that level. The occupied bandwidth tests were performed by D.L.S. Electronics at modulation levels of 0, 1/3, 2/3 and full levels and the appropriate plots are included in the D.L.S. test report. The signal is composed of repeating addressing intervals of 10 ms which are made up of 9 subintervals of .8ms each. Each of these subintervals forms either a 0 or a 1 bit by varying the ratio of on to off time. For a 1 bit, the signal is high for .6ms and low for .2 ms and for a 0 bit the signal is high for .2ms and low for .6ms. After the 9 subintervals a sync interval of 2.8ms is provided before the next addressing interval begins. The following diagram shows the makeup of the modulating signal: Fleetwood Group Inc.

FCC ID: FBR-TX216SYN-2 Test Procedure Page 3 of 3 File Name: TXTEST.DOC Date: 11/15/99 3.2 Description The test fixture uses a 36 pin edge connector for all electrical connections to the UUT: Power is supplied at 9 Volts (dropped through a 20 Ohm resistor). Current is measured with a front panel in-line meter. The channel may be selected simultaneously on both the UUT and the internal receiver through the integral processor on the modified Reply CRS1200 Keypad. The UUT interfaces using ‘CHSEL’. The keypad will have special test fixture code that: a) Maintains the receiver active upon any key press (aside from clear). b) Never activates its own transmitter. c) Cycles through the receive channels as the ‘#’ key is pressed. d) Selects the (same) channel on the UUT through a 3-wire bus. e) Activates and de-activates a transmitter data test waveform (called “MODULATION”) upon command. f) Allows a reset function when “Clear” is pressed. The fixture has two means of setting the UUT TX channel: a) The synthesizer three-wire bus is available through a 25 pin jack (suitable for a computer parallel interface connection). This means has no specific purpose other that providing future access to the three wire bus for diagnostic purposes. b) The ‘CHSEL’ lines (AVRSEL, AVRCLK, and AVRDATA). This connection normally operates as general purpose serial data interface. However, if four lines are held high simultaneously (TXPWR, F4, F5, and SYNPWR as controlled by SW4) then the serial bus changes modes to accommodate a channel selection (AVRSEL=LSB, AVRDATA=MSB). The Reply CRS1200 Keypad is used to output the demodulated FM signal as required to check the transmitter fidelity. It uses an antenna that is integral to the test set. The UUT receives a modulation signal as provided The modulation signal simulates the true transmitter data stream; it is activated and deactivated with SW1. The UUT has an internal processor that is programmed through U6. The control of the programming function is accomplished through an external computer connected with a 25 pin RS-232 jack. The UUT processor may be reset by toggling SW3 to ground.

Fleetwood Group Inc. FCC ID: FBR-TX216SYN-2 Fleetwood Test Report Page 1 of 3 File Name: FWTEST.DOC Date: 11/15/99 Test Report Introduction The Fleetwood Model TX216SYN Transmitter was designed to operate under Part 90.259. Because of its low output power (less than 120 milliwatts) it is exempt from some of the Part 90 requirements according to 90.217. However, the full testing is still required to document its performance. The majority of the tests were performed by D.L.S. Electronic Systems. The D.L.S. Test Report consists of 70 pages and identifies at the appropriate locations the tests that were not performed by D.L.S. They are as follows: Section 7.0 Modulation Characteristics Part 2.1047 The modulation characteristics are discussed in more complete detail in the operational description. The Model TX216SYN transmitter operates with Frequency Shift Keyed (FSK) binary data with +/- 10 KHz nominal deviation. It is modulated from a signal provided by a crystal controlled microprocessor part of Model CRS920, separately compliance tested for its digital circuits. Because there are no audio circuits, there is no audio response characteristic because the modulating signal can only vary between 0 and 5 volts. However, to demonstrate the modulation characteristics of the transmitter, tests at modulation levels of 0, 1/3, 2/3 and full levels were made and the appropriate plots are included in the D.L.S. test report and modulation waveforms are shown in the section “Operational Description.” Section 12.0 Frequency Stability (Temperature) Part 2.1055a Included in this section are the results of the tests performed at Fleetwood Group Inc. demonstrating the performance of the transmitter with variation in temperature. Section 13.0 Frequency Stability (Supply) Part 2.1055d Included in this section are the results of the tests performed at Fleetwood Group Inc. demonstrating the performance of the transmitter with variation in supply voltage. Conclusion: The results of the Fleetwood Group Inc. tests and the D.L.S. Electronics show that the Model TX216SYN transmitter meets the interference emission requirements of the FCC Part 90.

The tests were performed according to the procedures of FCC as stated in Part 2 Subpart J, Equipment Authorization Procedures of the Code of Federal Regulations 47, by personnel of D.L.S. Electronic Systems, Inc. who are responsible to Donald L. Sweeney, Senior EMC Engineer. 3.0OBJECT The purpose of this series of tests was to determine if the test sample could meet the radio frequency emission requirements of the FCC "Rules and Regulations", Part 90, Subpart I, Sections 90.205 to 90.209, 90.217 & 90.259 for Private Land Mobile Services operating in the 216 MHz to 220 MHz Frequency Band. 4.0TEST SET-UP All radiated emission tests were performed at D.L.S. Electronic Systems, Inc. The radiated tests were made with the test item placed on a wooden turntable located in the Test Room with the receive antenna placed one meter from the device under test. EMC Test ServicesReport No. 7686 1250 Peterson Drive, Wheeling, Illinois 60090, USA11/09/99 Page 9 5.0TEST EQUIPMENT (Bandwidths and Detector Function) All data was automatically plotted using peak detector function. This information was then used to determine the frequencies of maximum emissions. Manual measurements were performed on these frequencies using a peak detector function of the Analyzer with the bandwidths specified by the FCC. From 200 MHz to 1000 MHz a bandwidth of 100 kHz was used (except for Occupied Bandwidth), and above 1000 MHz, wide enough bandwidths were used, depending upon the test being made, to ensure proper measurement of the narrowband signal. A list of the equipment used can be found in Table 1. All equipment was calibrated per the instruction manuals supplied by the manufacturer. 6.0RF POWER OUTPUT - PART 2.1046 As stated in PART 90.205 (c), the output power should not exceed the rated output power of the Transmitter 216-220 MHz transmitter by 20%. The RF output power was measured at the RF output terminal of the transmitter with the transmitter tuned according to the tune-up procedures specified in Part 2.1033 (c-9), and adjusted for its maximum output power. The RF output power was measured in the open field, using the following test method: The radiated signal from the EUT was measured. The EUT was then substituted with a signal generator and a tuned dipole antenna. The output of the signal generator was increased until the level received by the tuned dipole equaled that of the previous measured from the EUT. Actual Measurements Taken: 120.50 dBuV Measured output of the transmitter +2.95dBuV Total system losses (Antenna, Pads & Cable) 123.45 dBuV which equals 0.0443 mW LIMIT: Manufacturer's rated output power = 0.05 mW MARGIN: 0.05 mW - 0.043 mW = 0.0057 mW NOTE: See the following pages for th…
