Chapter 1 Introduction 1.1 Purpose and Use The Miltel Transmitter (FCC ID: MLLSPEEDTXP45-47) 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.
Chapter 2 Theory of Operation 2.1 General Description The Miltel TxP 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).

2.2 Block Diagram Description 2.2.1 General Figure 2-2 describes the block diagram of the Miltel Transmitter 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).
2.2.2 Description of Operation The digital section of the Miltel Transmitter performs the following functions: Samples analog sensors OR communicates with digital sensors Accumulates data for each sensor separately Stores data (including alarms) in internal memory Interfaces the data to the RF section The controller gathers the data for 1-240 minutes before initiating a transmission.
Chapter 3 Technical Characteristics 3.1 Technical Specification 3.1.1 Electrical Max Effective Radiated Power (ERP) 116 mW Output frequency 450-470 MHz Carrier wave modulation 2 Level FSK Power supply Lithium battery, 3.0-3.6 Volt Input Channels Pulse / Analog / Digital Duration between automatic transmissions At least 10 Min. 3.1.
Chapter 4 Installation Instructions 4.1 General The Miltel 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 TxP Transmitter device, proceed as follows: 1) Loosen the four screws fastening the unit's box and open the box cover.
6) Close the unit's box cover. 7) Perform a functional radio transmission test by touching the side of the transmitter enclosure with a strong magnet (trigger transmission). Verify the correct reception of the data at the base station (concentrator). Update water actual readings for the respective meter. 8) Close the four screws fastening the cover. 9) Insert plastic protection plugs.
Chapter 5 Regulatory Compliance 5.1 FCC Statement The Speed TxP transmitter has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. 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.
