This device is installed on-site by a professional field technician, thus it includes technical terms. The equipment is not to be installed by a non-professional individual that has not been trained and authorized. 1.2 System General Description The Speed HPTx system is a computerized fully automatic radio device. It requires no human intervention after initial installation. The system enables remote, continuous and accurate reading of water or gas consumption. The Speed HPTx transmits the data acquired from water meters to a receiver connected to a regional concentrator. The concentrator transfers the data to the central computer for data collection and for further analysis and reporting. Chapter 2 Theory of Operation 2.1 General Description The Speed HPTx is the first link in the meter readings data collection system. It is an independent unit that does not require an external power source, wiring, or the preparation of an infrastructure. The unit is installed in proximity to the meters and can be connected to several adjacent meters. Figure 2-1 (see next page) shows a typical installation of a Speed HPTx unit, connected to several water meters (of various types) at a single location. The unit can be connected to any type of meter which has a pulsed output (a passive magnetic open/short reed relay), an active pulse or an encoded output. The Speed HPTx acquires the consumption data from the water meters and stores this data in its memory. The unit includes a miniature RF transmitter which transmits data on a periodic basis to a regional concentrator. Figure 2-1: Speed HPTx Typical Installation 2.2 Block Diagram Description 2.2.1 General Figure 2-2 describes the block diagram of the Speed HPTx unit. This device consists of two major sections, all using a common power source: ! Digital section (Micro Controller) ! RF section Transmitter (Speed Clamp A 3.6 volts Lithium battery provides power to all parts of the device. The power supply for the RF section is controlled via the Tx switch (not shown), thus cutting of power to the transmitter unless necessary for actual data transmission (standby mode). Figure 2-2: Speed HPTx Block Diagram Meter 1 Meter n Sensing and Support Circuitry Micro- Controller RF Transmitter Antenna Battery Device Enclosure Magnetic Switch Tamper Switch 2.2.2 Digital Section The digital section of the Speed HPTx performs the following functions: ! Samples reed switches to detect short/open from each meter. ! Accumulates number of pulses for each meter separately ! Stores data (including battery and tamper alarms) and stores information internal memory ! Interfaces the data to the RF section The digital section is based on a central controller which accepts the following inputs: a. Analog inputs (from reed-relay contacts) designated INPUT1 through INPUTn, each indicating the advance of a single water meter. Alternatively, the Speed HPTx interfaces to an encoded meter. These are the only inputs of the controller. b. Magnetic switch input is utilized only for testing. c. The TAMPER SWITCH input is connected to a micro- switch that senses an opening of the unit's box. This enables the Speed HPTx to generate and transmit an alarm signal in the event of unauthorized opening of the unit casing. d. The LOW VOLTAGE input of the controller is connected to battery via a Low Voltage Detector in order to sense and generate a low battery alarm. Each of the external analog inputs to the controller advances a separate counter in singular steps. The counters in the controller are not pre-settable or resettable to avoid unauthorized tampering (counter matching is thus perform…

Tune-Up Information The transmitter device has only one trimmer (see C7 in RF section of transmitter schematics) for adjusting and tuning the output frequency. All the other parameters (power, modulation bandwidth and timing) are pre-set to a fixed value and are not changeable or adjustable. The alignment procedure involves a setup that includes a synthesized spectrum analyzer. The output signal is monitored on the spectrum analyzer with a scan-width of 20 KHz. The center of the modulated output waveform is adjusted to within +/- 2 KHz. of the center frequency. This adjustment procedure is performed on the finished and complete unit as a final test before cover closure (after cover closure the transmitter parameters are verified again). This testing procedure is done while the transmitter antenna is brought to the proximity of a wire antenna connected to the spectrum analyzer.

FCC ID:MLLSPEEDHPTX450 Transmitter, model Speed HPTx Exposure limit according to part 1, §1.1310 Limit for power density for general population/uncontrolled exposure is 1 mW/cm 2 . The power density P (mW/cm 2 ) = f/1500 (mW/cm 2 ) = 0.3 mW/cm 2 = P T / 4π r 2 , where P T - the transmitted power, which is equal to the transmitter output. Maximal P T = 17.78 dBm ≈ 60 mW . 0.3 (mW/cm 2 ) = 60 mW / 4π r 2 The minimum allowed distance “r”, where RF exposure limits may not be exceeded, is 4 cm. r = sqrt ( P T / 4π) = sqrt(60/ 0.3 x 4 x 3.14) = 4 (cm). The public cannot be exposed to dangerous RF level.

Test Report Date: April, 2002 FCC ID:MLLSPEEDHPTX450 4.6 Transient Frequency Behavior according to FCC part 90 Paragraph 214 4.6.1 General This test was performed to determine the maximum frequency difference limits during the time intervals as defined in part 90 paragraph 214. 4.6.2 Test Procedure The transmitter was tested for transient frequency behavior using the test methodology defined in TIA/EIA-603-A (2.2.19.3). The test set up is depicted below in Figure 4.6.1. The functions of the RF power meter and the test receiver were performed by a Marconi FM Detector (HL793). The scope (HL 670) was triggered by a signal from the transmitter.
