These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-Consult the dealer or an experienced radio/TV technician for help. Chapter 1 Introduction 1.1 Purpose and Use The Speed HPTx (FCC ID: MLLSPEEDHPTX15-17) is a data link transmitter that is used for data acquisition in Miltels water consumption readings collection system. 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. 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 consumption. The Speed HPTx transmits the data acquired from water meters to a regional. 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 water readings 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 water meter/s and is connected to several adjacent meters. Figure 2-1 (see next page) shows a typical installation of a Speed HPTx unit, connected to several 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). 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. Transmitter

(Speed Clamp 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 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). M e t e r 1 M e t e r n Battery Antenna Sensing and Support Circuitry Micro-

Controller RF Transmitter Magnetic Switch Tamper Switch Device Enclosure Figure 2-2: Speed HPTx Block Diagram 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. These are the only inputs of the controller which are connected to the external source. b. Magnetic switch input is utilized only for test. 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 performed only by the central computer, ensuring excellent data security at the sites). The controller gathers the data for several hours before initiating a transmission. If any of the counters has advanced by more than a preset value, or any alarm (tamper or low voltage) has been received, the controller generates a single message immediately. Any further message will include alarm information along with counter data, if alarm condition still exists. Note: The duration interval between two transmissions is always greater than 1 Hr. a. The messages generated by the controller are 16 bytes each, and are outputed from the digital section to the RF section as serial data (RS-232 standard protocol) via the DATA OUT output of the controller. b. The Tx control output of the controller is used for activating the TX switch for the duration of the message, to enable power supply to the RF section thus enabling the transmission of the message (transmit mode). 2.2.3 RF Section The RF section consists of a phased-locked loop (PLL) and a low-power amplifier connected to an integral antenna. The PLL reference is driven by a 20.0 MHz. crystal oscillator. This reference is phase-compared by the Phase Detector with the divided output frequency. The phase detection signal from the detector is filtered by the PLL Loop Filter and then summed with the shaped signal received from the digital section by the Sum Network block. The output of the Sum Network is the control signal that modulates and locks the Voltage Control Oscillator (VCO).

The Speed HPTx installation is performed using a stainless steel clamp that enables connection to pipelines of different diameters (0.75", 1.00", 1.50" or 2.00"). The Speed HPTx unit is protected so that it is impossible to open or dismantle the box without breaking the four one-time screw locks. 4.2 Installation For on-site installation of the Speed HPTx device, proceed as follows:

1) 2) Loosen the four screws fastening the unit's box and open the box cover. Install the unit's box base as required:

a. For pipeline installations (as in Figure 2-1), first attach the stainless steel clamp (see Figure 4-1) to the pipeline, close it around the pipeline and fasten the screw in the middle of the device. Place the unit's box base on top of the screw and install it using two steel screws. b. For wall mounting of the unit, install the base directly onto the wall or surface using the two steel screws. 3) Connect the wire pairs from the water meters to the terminal blocks on the PCB. Up to four such pairs can be connected, with unused connections left open (i.e., no termination is required). Note Connect each pair of wires to the respective terminals; note the connections for future reference. 4) 5) Close the unit's box cover. Perform functional radio test by touching box corner with strong magnet

(trigger transmission). Verify correct reception of data at base station

(concentrator). Update water actual readings for the respective meter. 6) Close the four screws fastening the cover. 7) Insert plastic protection plugs. Figure 4-1: Speed HPTx - Pipeline Installation
