AMR OVERVIEW
Chapter Two
Automated Meter Reading Overview
The TRACE system uses radio frequency (RF) signals to allow utility
personnel to read meters from a distance while the reader is in motion.
This technology is called automated meter reading (AMR). This
technology greatly increases the speed at which routes can be covered
with a high degree of accuracy.
Basic AMR Components
An automated meter reading system requires the following basic
components:
Transponder—The transponder Interfaces with meter index
mechanics, translates index reading into digital signals to capture
data from meter, receives commands from an interrogator and
transmits meter data.
Interrogator—At its simplest, the interrogator remotely reads meter
data transmitted by transponders. At more sophisticated levels an
interrogator may also program transponders, store route data,
selectively “wake up” transponders, verify transponder conditions
and data and set meter coordinates, among other functions.
Antennas—Both the transponder and the interrogator use antennas
to broadcast and receive RF signals. The transponder’s antenna is
typically located on the circuit board inside the transponder case.
Some interrogators use external antennas (as shown in the
illustration below), one for transmitting and one for receiving. Many
handheld interrogators use a single antenna for both transmitting and
receiving (antenna may be internal or external).

TRACE AMR OVERVIEW
The TRACE AMR System Overview
In addition to standard automated meter reading functions, AMCO
Automated Systems’ TRACE portfolio of products permits the remote
recording of tamper conditions and linking of meter latitude and longitude
data using a Global Positioning Satellite (GPS) system. With the optional
Vehicle Interactive Display, TRACE makes driver-to-meter orientation
more intuitive and efficient.
TRACE interrogators transmit at 451.35 MHz and receive transponder
messages at 415 MHz. (Transponders transmit at 415 MHz and receive
at 451.35 MHz.)
Trace transponders, normally asleep, “wake up” and listen for an
interrogation signal once every second. Only if a transponder hears its
unique serial number will it transmit data back to the interrogation device,
and then it goes back to sleep. Under normal circumstances
transponders only send one transmission per month.
How the TRACE System Works
Utility personnel no longer have to walk up to each meter, look at its
index and record its reading. Once transponders are installed on meters
and programmed, meter readers simply walk or drive down each street in
the route allowing the TRACE interrogator to request and record meter
data automatically.

The interrogator addresses each transponder in the interrogation window individually. When the transponder “hears” its serial number and proper authorization, it
transmits the current meter data. The TRACE system’s frequency band allows remote reading of transponders even through walls and fences.
Acquisition of meter information begins with the transponder where data
is stored continuously for later retrieval and moves to the interrogator
upon command. The acquired data from a given route can be transferred
to a host computer via floppy disk for processing.

AMCO Automated Systems • P/N 52845G120 Rev 1 FEB 2004
Page 5
TRACE AMR OVERVIEW
The information acquisition, storage and handling process includes
several basic elements:
Meter interface. Using a mechanical-to-digital interface, the TRACE
transponder senses the output from the index of a utility meter, translates
this into electronic form and stores it in the transponder’s memory.
Transponder data acquisition. The transponder is programmed with a
unique serial number at the time of manufacture. Upon installation on a
meter, the current (or baseline) meter index reading is also programmed
into the transponder’s memory. As the meter reading advances it
automatically updates transponder memory. The transponder also
records changes to the tamper detection sensor.
Compensation factor. For TRACE transponders using firmware
Version 9 or higher, a compensation factor can also be programmed into
the transponder memory ensuring the transponder readings match the
compensated mechanical index reading.
Route information loading. Route data includes meter account number,
address and latitude/longitude coordinates (when available), and
transponder serial number. This information, along with Guide and Start
files, is downloaded to the interrogator prior to commencing automated
meter reading. By also tracking the vehicle or interrogator’s coordinates,
a GPS-equipped system determines which transponders in the route
should lie within range at any given time and transmits those serial
numbers requesting meter data.
Interrogation. Once placed in an interrogation mode by the meter
reader, the TRACE interrogator transmits serial number(s) of the desired
transponder(s) along with a command requesting the contents of each
transponder’s memory. Transponders are selected for reading on the
basis of route and meter location information stored in the interrogator
and presence of the transponder within range of the interrogator.
Route data processing. Meter data from transponders is stored in the
interrogator’s memory and can be transferred to the utility’s host
computer for processing.

URFI OVERVIEW
Chapter Three
Universal RF Interrogator Overview
The TRACE Universal RF Interrogator is a plug-in adapter that allows
any current DOS-compatible handheld data terminal to transmit and
receive data from TRACE transponders.
With the URFI, your existing investment in handheld terminals can
accommodate manual reads as well as TRACE automated meter reads.
URFI Components
The URFI consists of the following components that effectively turn your
existing DOS-based handheld terminal into TRACE interrogator:
Universal RF Interrogator unit
URFI carrying pouch
Transmitting antenna and coaxial cable
Receiving antenna and coaxial cable
Antenna bracket
Battery pack with cigarette lighter adapter and cable
Battery pack carrying pouch
RS232 communications cable
A/C power adapter
How the URFI Works
When the URFI is properly interfaced to a handheld data terminal, it
becomes an interrogator that stores route information in the terminal and
automatically acquires meter data remotely as the meter reader walks or
drives along the specified routes.
When interrogating, the URFI sends out a radio frequency (RF) signal
containing the IDs of transponders in the particular route. When a
transponder receives the signal containing proper authorization and its
unique serial number, the transponder replies by transmitting stored
meter data including index reading, tamper status and an error detection
code to ensure accuracy.
Meter reads can be captured in any order by simply pressing one key on
the handheld terminal’s keypad as designated by your host
programming.

URFI OVERVIEW
Power
Battery pack. A detachable battery pack allows the user to keep a spare
battery pack in the vehicle for extended service time.
A/C adapter. The battery may also be recharged by connecting the
battery back via its A/C adapter to a normal 120 VAC outlet.
On/Off control. On/Off control of the URFI is done by the handheld
terminal to maximize battery performance.
Communications
The URFI’s belt-mount design interfaces via RS232 serial link to a
handheld computer or, where required, a laptop PC.
NOTE: For the purposes of this document, from this point forward the
handheld/laptop computing device will be referred to as simply the
handheld terminal.
Data Processing
No route data is stored at the URFI level. All field processing and storage
of route data is managed by the handheld terminal.
Software. TRACE ReadIt™ is the software used in the selected
handheld or laptop computer to provide for both manual and automated
meter reading functions. This dual-mode functionality allows a utility the
convenience of automating any route in stages.
Route data. Routes are loaded into the handheld terminal or laptop
memory using your own route management system or via Pantheon
Route Manager, AMCO Automated Systems’ host software package.
Stored route data includes customer name, address, account number,
meter number, unique transponder ID, hi/lo warning limits, time and date
of read, utility-definable trouble codes and alphanumeric messages,
along with the meter reading itself.
Data transfer from handheld. At the end of a shift, stored meter reading
information is transferred from the handheld terminal to the host package
for ultimate use in billing systems for processing.
Transmission Accuracy
Data accuracy is assured by a three-part process:
1.
Patented TRACE technology ensures that a transponder is triggered
to respond only when it receives a properly authorized transmission
of its unique serial number from the URFI (or any other AMCO
Automated Systems interrogator).
Universal RF Interrogator ? Installation Guide
AMCO Automated Systems • P/N 52845G120 Rev 1 FEB 2004
Page 8
URFI OVERVIEW
2.
The transponder then calculates an error-detection code which must
be verified by the handheld terminal before the transponder data can
be acquired and stored.
3.
The ReadIt software compares the current meter reading with hi/low
audit values (established by the billing department and entered into
the route file prior to reading meters) and it looks for readings that fall
outside those limits. The handheld terminal can be programmed to
issue audible or visual warnings when a read value exceeds preset
limits, regardless whether the read was acquired manually or
automatically via RF.
RF Signals and Conditions
URFI Range. As a rule, transponders within approximately 300 feet of
the URFI (with no obstructions between URFI and transponder) should
receive interrogation signals and respond appropriately. Indoor meters
can be read through most walls from a distance of up to 100 feet.
Obstructions. Line-of-sight provides the optimum transaction range.
Although the URFI can read transponders through walls and fences, any
obstacles between the URFI and transponder may reduce the range at
which successful transactions may be conducted. Metallic obstacles
(vehicles, trash cans, metal sheds, etc.) in the path will severely impede
or block the transmission of RF signals.
Transaction Capacity. The URFI can interrogate and acquire
transponder data in less than two seconds per transponder.

AMR OVERVIEW
Chapter Two
Automated Meter Reading Overview
The TRACE system uses radio frequency (RF) signals to allow utility
personnel to read meters from a distance while the reader is in motion.
This technology is called automated meter reading (AMR). This
technology greatly increases the speed at which routes can be covered
with a high degree of accuracy.
Basic AMR Components
An automated meter reading system requires the following basic
components:
Transponder—The transponder Interfaces with meter index
mechanics, translates index reading into digital signals to capture
data from meter, receives commands from an interrogator and
transmits meter data.
Interrogator—At its simplest, the interrogator remotely reads meter
data transmitted by transponders. At more sophisticated levels an
interrogator may also program transponders, store route data,
selectively “wake up” transponders, verify transponder conditions
and data and set meter coordinates, among other functions.
Antennas—Both the transponder and the interrogator use antennas
to broadcast and receive RF signals. The transponder’s antenna is
typically located on the circuit board inside the transponder case.
Some interrogators use external antennas (as shown in the
illustration below), one for transmitting and one for receiving. Many
handheld interrogators use a single antenna for both transmitting and
receiving (antenna may be internal or external).

TRACE AMR OVERVIEW
The TRACE AMR System Overview
In addition to standard automated meter reading functions, AMCO
Automated Systems’ TRACE portfolio of products permits the remote
recording of tamper conditions and linking of meter latitude and longitude
data using a Global Positioning Satellite (GPS) system. With the optional
Vehicle Interactive Display, TRACE makes driver-to-meter orientation
more intuitive and efficient.
TRACE interrogators transmit at 451.35 MHz and receive transponder
messages at 415 MHz. (Transponders transmit at 415 MHz and receive
at 451.35 MHz.)
Trace transponders, normally asleep, “wake up” and listen for an
interrogation signal once every second. Only if a transponder hears its
unique serial number will it transmit data back to the interrogation device,
and then it goes back to sleep. Under normal circumstances
transponders only send one transmission per month.
How the TRACE System Works
Utility personnel no longer have to walk up to each meter, look at its
index and record its reading. Once transponders are installed on meters
and programmed, meter readers simply walk or drive down each street in
the route allowing the TRACE interrogator to request and record meter
data automatically.

The interrogator addresses each transponder in the interrogation window individually. When the transponder “hears” its serial number and proper authorization, it
transmits the current meter data. The TRACE system’s frequency band allows remote reading of transponders even through walls and fences.
Acquisition of meter information begins with the transponder where data
is stored continuously for later retrieval and moves to the interrogator
upon command. The acquired data from a given route can be transferred
to a host computer via floppy disk for processing.
The information acquisition, storage and handling process includes
several basic elements:

AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004
Page 5
TRACE AMR OVERVIEW
Meter interface. Using a mechanical-to-digital interface, the TRACE
transponder senses the output from the index of a utility meter, translates
this into electronic form and stores it in the transponder’s memory.
Transponder data acquisition. The transponder is programmed with a
unique serial number at the time of manufacture. Upon installation on a
meter, the current (or baseline) meter index reading is also programmed
into the transponder’s memory. As the meter reading advances it
automatically updates transponder memory. The transponder also
records changes to the tamper detection sensor.
Compensation factor. For TRACE transponders using firmware
Version 9 or higher, a compensation factor can also be programmed into
the transponder memory ensuring the transponder readings match the
compensated mechanical index reading.
Route information loading. Route data includes meter account number,
address and latitude/longitude coordinates (when available), and
transponder serial number. This information, along with Guide and Start
files, is downloaded to the interrogator prior to commencing automated
meter reading. By also tracking the vehicle or interrogator’s coordinates,
a GPS-equipped system determines which transponders in the route
should lie within range at any given time and transmits those serial
numbers requesting meter data.
Interrogation. Once placed in an interrogation mode by the meter
reader, the TRACE interrogator transmits serial number(s) of the desired
transponder(s) along with a command requesting the contents of each
transponder’s memory. Transponders are selected for reading on the
basis of route and meter location information stored in the interrogator
and presence of the transponder within range of the interrogator.
Route data processing. Meter data from transponders is stored in the
interrogator’s memory and can be transferred to the utility’s host
computer for processing.

URFI OVERVIEW
Chapter Three
Universal RF Interrogator Overview
The TRACE Universal RF Interrogator is a plug-in adapter that allows
any current DOS-compatible handheld data terminal to transmit and
receive data from TRACE transponders.
With the URFI, your existing investment in handheld terminals can
accommodate manual reads as well as TRACE automated meter reads.
URFI Components
The URFI consists of the following components that effectively turn your
existing DOS-based handheld terminal into TRACE interrogator:
Universal RF Interrogator unit
URFI carrying pouch
Transmitting antenna and coaxial cable
Receiving antenna and coaxial cable
Antenna bracket
Battery pack with cigarette lighter adapter and cable
Battery pack carrying pouch
RS232 communications cable
A/C power adapter
How the URFI Works
When the URFI is properly interfaced to a handheld data terminal, it
becomes an interrogator that stores route information in the terminal and
automatically acquires meter data remotely as the meter reader walks or
drives along the specified routes.
When interrogating, the URFI sends out a radio frequency (RF) signal
containing the IDs of transponders in the particular route. When a
transponder receives the signal containing proper authorization and its
unique serial number, the transponder replies by transmitting stored
meter data including index reading, tamper status and an error detection
code to ensure accuracy.
Meter reads can be captured in any order by simply pressing one key on
the handheld terminal’s keypad as designated by your host
programming.

URFI OVERVIEW
Power
Battery pack. A detachable battery pack allows the user to keep a spare
battery pack in the vehicle for extended service time.
A/C adapter. The battery may also be recharged by connecting the
battery back via its A/C adapter to a normal 120 VAC outlet.
On/Off control. On/Off control of the URFI is done by the handheld
terminal to maximize battery performance.
Communications
The URFI’s belt-mount design interfaces via RS232 serial link to a
handheld computer or, where required, a laptop PC.
NOTE: For the purposes of this document, from this point forward the
handheld/laptop computing device will be referred to as simply the
handheld terminal.
Data Processing
No route data is stored at the URFI level. All field processing and storage
of route data is managed by the handheld terminal.
Software. TRACE ReadIt™ is the software used in the selected
handheld or laptop computer to provide for both manual and automated
meter reading functions. This dual-mode functionality allows a utility the
convenience of automating any route in stages.
Route data. Routes are loaded into the handheld terminal or laptop
memory using your own route management system or via Pantheon
Route Manager, AMCO Automated Systems’ host software package.
Stored route data includes customer name, address, account number,
meter number, unique transponder ID, hi/low warning limits, time and
date of read, utility-definable trouble codes and alphanumeric messages,
along with the meter reading itself.
Data transfer from handheld. At the end of a shift, stored meter reading
information is transferred from the handheld terminal to the host package
for ultimate use in billing systems for processing.
Transmission Accuracy
Data accuracy is assured by a four-part process:
1.
Patented TRACE technology ensures that a transponder is triggered
to respond only when it receives a properly authorized transmission
of its unique serial number from the URFI (or any other AMCO
Automated Systems interrogator).
Universal RF Interrogator ? Host Programming Guide
AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004
Page 8
URFI OVERVIEW
2.
The transponder then calculates an error-detection code which must
be verified by the handheld terminal before the transponder data can
be acquired and stored.
3.
The ReadIt software compares the current meter reading with hi/low
audit values (established by the billing department and entered into
the route file prior to reading meters) and it looks for readings that fall
outside those limits. The handheld terminal can be programmed to
issue audible or visual warnings when a read value exceeds preset
limits, regardless whether the read was acquired manually or
automatically via RF.
4.
Upon rec eipt of a response, the URFI checks the transmission
frequency of incoming data to verify it is a valid frequency range for
TRACE transponders.
RF Signals and Conditions
URFI Range. As a rule, transponders within approximately 300 feet of
the URFI (with no obstructions between URFI and transponder) should
receive interrogation signals and respond appropriately. Indoor meters
can be read through most walls from a distance of up to 100 feet.
Obstructions. Line-of-sight provides the optimum transaction range.
Although the URFI can read transponders through walls and fences, any
obstacles between the URFI and transponder may reduce the range at
which successful transactions may be conducted. Metallic obstacles
(vehicles, trash cans, metal sheds, etc.) in the path will severely impede
or block the transmission of RF signals.
Transaction Capacity. The URFI can interrogate and acquire
transponder data in less than two seconds per transponder.

URFI Host Programming
Customer Serial Interface
This chapter provides host programming information for the TRACE
Universal RF Interrogator.
Changes
The following changes have been implemented since Beta model:
Pressure Compensation
New Command for V9 support of Pressure Compensation Factors (see
PC and RC)
Power On/Off
Change Power On/Off from RTS (pin 7) to DTR (pin 4) and other small
corrections.
URFI Attributes and Performance Characteristics
1.
Communications. The URFI uses a 9-pin RS232C cable
connection, with a Baud rate of 19200, 8 bits, and no parity.
2.
Protocol. The basic protocol between the Customer Application S/W
(S/W) and the URFI is as Master to Slave. The S/W will originate all
commands and the URFI will provide an acknowledgment within a
maximum time interval (different for each command).
3.
Power-on. The first “command” is turning on power to the URFI.
This is controlled by the DTR line (pin 4) in the serial port. This will
produce a cursor “URF>” when the URFI has initialized and is ready
for a command ( < 300 msec).
4.
Power-off. Power-Down can be controlled the same way, the DTR
line, or with the Stand By (SB) command but the DTR uses much
less power (<0.5ma vs 100ma). SB can also be used as a
sleep/cradle mode, in which all commands would be ignored except
the Wake-Up command. This will allow the URFI to share the same
serial port with other devices or multiple URFIs.

URFI H OST PROGRAMMING
5.
Throughput enhancement. In between a command and its reply
the URFI will ignore the serial port, to reduce overhead and improve
throughput. If the URFI fails to respond in the maximum time for that
command the S/W can reset the URFI by toggling the serial port
DTR line.
6.
URFI response. After all replies, the URFI will resend the “URF>”
cursor to acknowledge it is ready for another command. Except after
the Stand-By or Power-Down commands, because it will not be
ready then. Invalid command strings will return “INVALID” at the
point where the error is found, and the rest of the command line is
ignored.
7.
Set-up. Setup parameters will all be saved in non-volatile memory
(EEPROM) so they can be set once, at the factory or with a PC. The
S/W will not be required to perform any special setup commands
each time the URFI is powered up. Use the “UE” command to save
the current setup to EEPROM as the new defaults.

[GA]
Where: G- = Normal Interrogation mode, 1.5 seconds of Dummies before each command.
G+ = run the transmitter continuously , sending Dummy Ints. between commands. About 15 times faster, when
conditions permit. (60 dummies before first Int. only)
nn = G+ mode Time-out (in seconds), reverts back to G- mode (default=30 sec.)
GA= Group mode Aborted, if Vbat<9V or Vcc<5V or TxPwr>~3W, and stops the Tx.
The G+ command will wait for 5 Dummies before returning. During this time it monitors the battery, Vcc and TxPwr and
returns GA if they are out of range. These items are also tested once a second when G+ is active, but no message is
sent if the Tx is aborted, but the next G+ will repeat these tests and will return GA if the condition still exits.
WARNING: “G+,00” will leave the transmitter on forever, but can overheat the URFI if it is not well ventilated, and will
drain a battery in about 30 minutes, so use with care.
The G+ command would be sent before the first SN in a group of meters known to be close together (such as in an
apartment building or a new shipment of meters on the loading dock). Then the transmitter will be left on between
commands, to keep all of the transponders awake, until the G- command is sent after the last SN in the group. This will
allow the whole group to be read in a fraction of the normal time. In applications where battery life is not a concern the
Group interrogate mode could be used all the time, to achieve near Van-like reading rates, but a G+ should still be sent
again periodically to verify proper operation.
Group mode is only possible when the URF is using antennas more than 3 feet apart or all transponders in the group are
within 10 feet, with the supplied antennas.
