3 Chapter 1 Introduction 1.1 Purpose and Use The Speed HPRx450 (FCC ID: MLLSPEEDHPRX450) is a data link transceiver that is used for data transfer in Miltel’s utility 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 that has not been trained and authorized. 1.2 System General Description The Speed HPRx450 system is a computerized fully automatic radio device. It requires no human intervention after initial installation. The device acts as a store-and-forward radio relay. The Speed HPRx450 captures any transmission from a Speed HPTx transmitter and, after validating the message, transmits the message again. The Speed HPRx450 relays information from meter reading transmitters to regional concentrators (which are equipped with a radio receiver). The concentrator transfers the data to the central computer for data collection and for further analysis and reporting.
4 1.3 Theory of Operation The Speed HPRx450 is the intermediate link in the meter readings data collection system. It is an independent unit that operates as a repeater (radio relay). Figure 2-1 (see below) shows a typical installation of a Speed HPRx450 unit. The device is powered by a 12 volt power supply or by a solar powered battery. The Speed HPRx450 operates its radio receiver on a continuous basis until it receives a message from a nearby transmitter. After capturing the transmitted data message, it sends out an identical message which is forwarded to the regional concentrator.

7 Chapter 3 Installation Instructions 3.1 General The Speed HPRx450 is installed by a professional technician. 3.2 Installation For on-site installation of the Speed HPRx450 device, proceed as follows: 1) Loosen the four screws fastening the unit's box and open the box cover. 2) Connect the 12 volt DC power supply (use only U/L approved power supply) 3) Install screws and mount to wall or to mast 4) Close case 5) Install antenna on a mast using the clamp provided Please Note: FCC RF exposure: Antenna Installation: The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20cm from all persons and must not exceed an antenna gain of 3 dBi. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 6) Connect the Coax cable at both ends – to the repeater and to the antenna 7) Perform functional radio test by using a Speed HPTx transmitter. Verify that the message is relayed by the repeater to the concentrator.
8 Whenever possible, the repeater should be installed indoors. If outdoor installation is required, the repeater should be installed within a weatherized enclosure.
