Chapter 1: System Overview
This document covers the setup and operation of the FIREFLY Radio Frequency
Automatic Meter Reading (AMR) system, used in conjunction with the RouteSTAR
Meter Reading System (RouteSTAR MVP).
All information presented herein assumes the installation and understanding of the
RouteSTAR MVP software and associated ROADRUNNER ruggedized, handheld
computers. Refer to the ROADRUNNER system manual and Training Guides for
additional information.
The RouteSTAR MVP system is designed to provide a fast, efficient method of
collecting meter reading data from a variety of sources. This includes FIREFLY AMR
meter readings as well as ProfilePLUS™historical usage data.
More specifically, utility meters are outfitted with FIREFLY Meter Interface Units
(MIUs) that transmit meter readings and associated information. Field personnel collect
these radio frequency readings via ROADRUNNERs equipped with an integrated Radio
Frequency Receiving Unit (RFRU) or ROADRUNNER Mobile.
Likewise, the MIUs provide a feature called ProfilePLUS to keep track of historical
usage data. This data helps solve billing disputes, and enable variable rate billing and
load management studies. ROADRUNNERs are used in conjunction with
Programming/Profiling Units (PPUs) for water FIREFLYs to extract this data on
demand.

FIREFLY Optical Sensor
The FIREFLY MIU uses a unique and
highly sophisticated optical sensor unit
to track meter activity. An infrared
strobe is integrated into the sensor and
generates its own light, regardless of
ambient conditions. The sensor is
oriented so that the register needle
approaches the sensor from the cable
side and perpendicular to the cable.
The indicators on the top side of the
sensor need to be aligned with the
passing sweep hand. As the needle
sweeps past the sensor, it changes the
light reflected back from the meter
face, and an incremental count is
registered.
The Optical Sensor is affixed to the
meter face using a high-bond adhesive
tape. Specifications for the tape follow.

Installation Preparation
Installation Considerations
1. Signal distance varies depending on the location of the MIU. FIREFLYsinstalled
above-ground generally transmit the greatest distance.
2. The material of a pit or vault lid affects the transmission range. For example, a
transmitter has a greater range sending from a pit with a plastic lid than a cast iron
lid.
3. Lids with holes of a diameter of roughly 1 3/4 inches make it possible to mount the
FIREFLY MIU through the lid. This can increase transmission range significantly.
4. Complete field installation of an MIU takes 5-10 minutes, depending on the meter
location and mounting application.
5. If the lid has a hole for the unit, use the
cap and wing nut assembly (“lid lock”
pictured at right). Ensure that enough
space exists between the box lid and
the ground for the unit to sit. If not,
remove some of the dirt from the
bottom of the box. Do not over-
tighten lid locks.
Water FIREFLY Installation
Installing the Optical Sensor-End FIREFLY
Meter Preparation
1. Remove meter box lid.
2. Survey the meter, checking lid, hole depth, and overall cleanliness.
3. Check for meter disqualifications and enter the corresponding skip code.
4. Clean excess dirt from meter lid, exposing meter number and verify it with the
account on the ROADRUNNER.
5. Flip lid back and pre-clean meter face/lens using Fast Orangenon-pumice cleaner
and a cloth or cotton swab to remove residue.
6. Clean meter face/lens with 99% isopropyl alcohol and a NEW lint-free cotton swab.
Note: Use Isopropyl rubbing alcohol, 99% by volume. Lower
concentrations do not clean or evaporate as well and adversely affect the
sensor-to-meter bond.

DRAFT
16 FIREFLY AMR REFERENCE MANUAL
DRAFT
©Datamatic.com, Ltd. 2000 - 2005
7. Re-wipe the surface of the meter lens with a clean, new cotton swab each time until
the swab comes up clean, and the clean lens squeaks when wiped.
8. After cleaning, ensure that the lens is completely dry; allow time for the alcohol to
evaporate
Background Check for Firmware Version 0210 and Prior
Sensor Firmware Versions Only
1. Connect the ROADRUNNER to the FIREFLY via the PPU.
2. On the ROADRUNNER 860 Press SHIFT I to display the FIREFLY main menu
and on the ROADRUNNER X7 press F5 .
3. For 0210 and prior sensor firmware versions, Press A to begin testing the FIREFLY
optics. For 0211 and future sensor firmware versions go to the Sensor Placement
section below.
Verifying
Sensor Placement
Background: 181
Status: [Success]
Test Again?
Y/N
The values shown are in decimal and the test keys on Power Level 2 (P2). A successful
test and sensor target placement is achieved when the P2 value is 60 or greater.
*After completing the sensor background test, determine if another alcohol cleaning is
needed on the register face prior to installation of the sensor.
Sensor Flap
Within each case of FIREFLYs, 24 rubber Sensor Flaps are included for every
installation. Utilizing these Sensor Flaps insures a stable environment during the
calibration process.
Sensor Placement
1. Insert sensor cable through sensor flap.
2. Remove the adhesive backing from the high-bond tape on the Optic Sensor face.
3. Install sensor to the location of the best background according to the background
check (for 0210 and prior sensor firmware version FIREFLYs).

DRAFT Chapter 1: System Overview 17
DRAFT
©Datamatic, Ltd. 2000 - 2005
4. Orient the sensor so the water meter needle approaches the sensor from the cable side
and perpendicular to the cable. There are indents on each side of the sensor base that
are to be in line with the needle when it passes.
5. Attach the sensor to the water meter lens
surface.
6. Since the 3M tape provides a pressure
sensitive seal, the installer must apply
16 lbs. of pressure to the MIU sensor
immediately after attaching to the lens
surface. The next step is to maintain
constant pressure for a minimum of 60
seconds.
Tip: Palm the sensor and lean
onto it to apply the
appropriate pressure.
7. A full cure on the seal is achieved in 24 - 96 hours. Do not touch, pull, move, or
handle the sensor in any way during this period.
8. Apply approved adhesive around the sensor to seal it completely in case the pit fills
with water prior to the 24 - 96 hour cure time, or if the meter face is curved and not
flat.
Note: If the sensor is initially misplaced, do not attempt to remove the
sensor by twisting the sensor body. A fully cured sensor requires
breaking the seal at the adhesive tape joint with a flat tool such as a
screwdriver. Insert the screwdriver between the aluminum base and
meter lens and twist.
9. Mount the FIREFLY MIU to an appropriate wall, stake or through hole in meter
box/vault lid with the threaded neck pointing up.
If using a stake, bury the stake in the ground adjacent to the meter register at least 6
inches. The platform area of the pole needs to face inward.
Position the MIU on the pole platform.
Attach the MIU to the pole with the binding material, such as a zip tie (14”).
If utilizing a lid lock, make certain NOT to over tighten the FIREFLY within the
lock. Also be sure to never rest the weight of the lid on the FIREFLY.
10. Place sensor flap over sensor, insuring a snug fit.
11. Program the MIU and set to "AutoCAL".
12. Prior to leaving, take an RF read.
Installing the Wire-end FIREFLY
1. Connect FIREFLY wire-end to meter contacts using Posi-lock connector or Gel caps.

2. Use approved method specified in the Training Guide for wire connections.
3. Mount the FIREFLY to an appropriate wall, stake, or through hole in the meter box /
vault lid.
4. If using a stake, bury the stake in the ground adjacent to the meter register at least 6
inches. The platform area of the pole needs to face inward.
5. Position the MIU on the pole platform.
6. Position the FIREFLY MIU with the threaded neck pointing up.
7. Attach the MIU to the pole with the binding material.
Note: Do not connect a multi-meter, probe or other interrogating device
to the FIREFLY wires. Doing so may cause the unit to globally reset,
erasing all programmed data!
Installing the Wire-end FIREFLY with a Logical Switch
The FIREFLY Logical Switch MUST be handled with care at all times. A drop or shock
of any kind could affect the performance of the Logical Switch.
Use the following instructions to install FIREFLYs:
1. Set Reading Mode to RV Mode.
Clean the Register
2. Clean the register with a rag to make sure there is no mud or dirt that would get
caught between the collar and glass.
Attach the Logical Switch to the Register
3. Place the Logical Switch on the register and secure with the two screws attached on
the switch.
Profile Data Extraction with Water FIREFLYs
When extracting profile data for an account loaded on the ROADRUNNER, always
enter the meter reading prior to profile extraction. With an RF-enabled
ROADRUNNER, utilize the Read and Verify function. With non-RF
ROADRUNNERs, enter the read manually.
Note: If extracting profile data for an account not loaded on the
ROADRUNNER, collecting the meter reading is not necessary.
Attach the 9-pin end of the Datamatic-supplied cable to the PPU and the other end to the
top port of the ROADRUNNER 860 or the side port of the ROADRUNNER X7.
Remove the rubber plug from the side of the MIU, uncovering the infrared port.
Make sure the optical windows for both the PPU and MIU are clean and unobstructed.
Snap the PPU onto the MIU and turn the PPU power on.
