Introduction
1.1 Purpose and Use
The Miltel Galaxy Remote 2 Transmitter (FCC ID: MLLGLXR2-TX450) 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 Remote2 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.

Theory of Operation
2.1 General Description
The Miltel Galaxy Remote 2 Transmitter is 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 Remote 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 Remote 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.

2.2 Block Diagram Description
2.2.1 General
Figure 2-2 describes the block diagram of the Miltel Galaxy Remote2 Transmitter.
This device consists of two major sections, all using a common power source:
Ø Digital section (Micro Controller)
Ø 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).

2.2.2 Description of Operation
The digital section of the Miltel Galaxy Remote 2 Transmitter performs the following
functions:
Ø Samples analog sensors OR communicates with digital sensors
Ø Accumulates data for each sensor separately
Ø Stores data (including alarms) in internal memory
Ø 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.

Installation Instructions
4.1 General
The Miltel Galaxy Remote 2 Transmitter is installed by a professional technician.
Several possibilities for installation have been programmed into the system in order to
provide solutions for installation of various types of sensors including water, gas or
electric meters.
4.2 Installation
For on-site installation of the Miltel Galaxy Remote 2 Transmitter device, proceed as
follows:
1) Mark the 4 locality of the screws on the wall.
2) Splice the wires coming from the transmitter with the wires coming from the
meter (Important: Keep the color coding consistent).
3) Close the box cover & screw the screws to the 4 place with screw driver, see
