Page 3 of 14 Miltel Galaxy Pit2 Transmitter Chapter 1 Introduction 1.1 Purpose and Use The Miltel Galaxy Pit 2 Transmitter (FCC ID: MLLGLXPT2) is a data link transmitter that is used for data acquisition in Miltel’s telemetric data 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 that has not been trained and authorized. 1.2 System General Description The Miltel data collection system is a computerized fully system incorporating one-way transmitters that automatically collect data from utility meters and/or other sensors. The system requires no human intervention after initial installation. The system enables remote, continuous and accurate reading of water or gas consumption. The Miltel Galaxy Pit2 transmits the data acquired from various sensors such as water meters, electric meters, to a receiver connected to a regional data concentrator. The concentrator transfers the data to the central computer for data collection and for further analysis and reporting.
Page 4 of 14 Miltel Galaxy Pit2 Transmitter Chapter 2 Theory of Operation 2.1 General Description The Miltel Galaxy Pit 2 Transmitters the first link in the data collection system. It is an independent unit that does not require an external power source, wiring, or the preparation of any special infrastructure. The unit is installed in proximity to the physical sensor and can be connected to several different sensors in parallel (for example four water meters of adjacent apartment, etc). Pictures 2-1 (see next page) show typical installations of a Miltel Galaxy Pit 2 Transmitter unit. The unit can be connected to any type of sensor which has a digital output, analog output, dry contact pulsed output (a passive magnetic open/short reed relay), or any active pulse or encoded output. The Miltel Galaxy Pit 2 Transmitter acquires the data from the sensor and stores this data in its internal memory. The unit includes a miniature RF transmitter which transmits the data on a periodic basis to a regional concentrator.

Page 6 of 14 Miltel Galaxy Pit2 Transmitter 2.2 Block Diagram Description 2.2.1 General Figure 2-2 describes the block diagram of the Miltel Galaxy Pit2 Transmitter. This device consists of two major sections, all using a common power source: ¾ Digital section (Micro Controller) ¾ 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).

Page 7 of 14 Miltel Galaxy Pit2 Transmitter 2.2.2 Description of Operation The digital section of the Miltel Galaxy Pit 2 Transmitter performs the following functions: ¾ Samples analog sensors OR communicates with digital sensors ¾ Accumulates data for each sensor separately ¾ Stores data (including alarms) in internal memory ¾ Interfaces the data to the RF section The controller gathers the data for 10-240 minutes before initiating a transmission. If any of the counters/sensors has exceeded a preset value, or any alarm (such as tamper) 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 60 minutes. The messages generated by the controller are 19 bytes each (depending on the number and type of sensors connected). The messages are exported from the digital section to the RF section as serial data (RS-232 standard protocol) via the DATA OUT output of the controller. 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). The RF section takes the message and transmits it through the RD circuitry.
