Introduction

1.1 Purpose and Use

The Miltel Transmitter (FCC ID: MLLCPTX450A) 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 CPTx transmits the data acquired from various sensors such as water

meters, electric meters, temperature or moisture sensors or any other analog or digital

sensor 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 CPTx 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, three ground moisture sensors at different depths, etc).

Pictures 2-1 through 2-3 (see next page) show typical installations of a Miltel CPTx

unit, connected various sensors. 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 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.
