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.

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.

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.

Whenever possible, the repeater should be installed indoors. If outdoor installation is
required, the repeater should be installed within a weatherized enclosure.
