AMR OVERVIEW Universal RF Interrogator ? Installation Guide Page 4 AMCO Automated Systems • P/N 52845G120 Rev 1 FEB 2004 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). Transponder METERThe interrogator sends out an RF signal to the desired transponders. Upon receiving an authorized command the transponder transmits its stored meter data. 1234 ABC 864 234 Maple DriveInterrogatorInterrogator transmits commands & queries to transponder(s) Transponder transmits meter data to the interrogator’s receiver
TRACE AMR OVERVIEW Universal RF Interrogator ? Installation Guide Page 5 AMCO Automated Systems • P/N 52845G120 Rev 1 FEB 2004 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. 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. SN 1111 Read 208… SN 2222 Read 943… MMI Equipped SN 3333 Read 510… SN 4444 Read 1031… TRANSMIT RECEIVE 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.
TRACE AMR OVERVIEW Universal RF Interrogator ? Installation Guide Page 6 AMCO Automated Systems • P/N 52845G120 Rev 1 FEB 2004 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 Universal RF Interrogator ? Installation Guide Page 7 AMCO Automated Systems • P/N 52845G120 Rev 1 FEB 2004 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 Universal RF Interrogator ? Installation Guide Page 8 AMCO Automated Systems • P/N 52845G120 Rev 1 FEB 2004 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).
URFI OVERVIEW Universal RF Interrogator ? Installation Guide Page 9 AMCO Automated Systems • P/N 52845G120 Rev 1 FEB 2004 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.

TRACE AMR OVERVIEW Universal RF Interrogator ? Host Programming Guide Page 6 AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004 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 Universal RF Interrogator ? Host Programming Guide Page 7 AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004 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 Universal RF Interrogator ? Host Programming Guide Page 8 AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004 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).
URFI OVERVIEW Universal RF Interrogator ? Host Programming Guide Page 9 AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004 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 Universal RF Interrogator ? Host Programming Guide Page 11 AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004 Chapter Four 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 HOST PROGRAMMING Universal RF Interrogator ? Host Programming Guide Page 12 AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004 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.
URFI HOST PROGRAMMING Universal RF Interrogator ? Host Programming Guide Page 13 AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004 URFI Command Conventions 1. Command termination. All commands end with a Carriage Return and Line Feed (not shown below). 2. Checkum On. When Check-Summing is on (CS+), commands and replies will be followed by a 2 digit ASCII-Hex sum as the last two characters, except for CheckSumOff (“CS -”) and Help (“?”). 3. Valid serial number characters. <sn> = a 1 to 8 digit Serial Number, with wild card digits as “?”. (H, E, L, and P are also valid). NOTE: SN digits not supplied will be assumed to be leading 0s. 4. Comments. Text in { } are comments, not data. 5. Text in Brackets. Text in [ ] will only appear as needed. (exceptions) 6. Option lists. Option lists are shown as: < x | y > = x or y.

If none is supplied any unit will respond. Check-Summing CS<+|-> {no reply, enable or disable checksums} Update EEPROM UE {no reply, save current options as defaults} The nn last used in SPnn, SOnn, and G+,nn and F1 and F2become the power-up defaults. Read Meter RM[<sn>][,T][,F<1|2>] <Reading>[,T<S|O|B>][,C<S|R|B>],<ss>,<bat> or R<N|B|C<ch>|A|J> Where: T = Send Clear Tamper with command. (if no <sn> use previous <sn>) F1 or F2 = use Frequency 1 or 2 (if no F use F1 at power on then last one sent) T = Tamper followed by either S = Short, O = Open or B = Both. C = Corrupted followed by S = Serial Number, R = Reading, or B = Both. <ss> = The received Signal Strength (>1.0v is usually good but 2.5 is a glitch) <bat> = Battery voltage during the Interrogation. ( 9 Volts =to low to transmitt) Or if no valid reading could be found, one of the following error messages will be sent: R = Reply: N = None (no data lock), B = Bad (bad BCH), A = Aborted (batt<9V or Tx>4W) RC<ch> =Data lock found on Channel <ch> (but not on the current channel), where: <ch> =-25 to +15 (0=415 MHz in 100KHz steps) (see LC command) (NOTE: only time to scan the current RcvCh+/-10 Channels) RJ = Receiver Jammed, data lock found before interrogation started, read aborted.

On Transponders with V9 code or later the Num/Denom is the Pressure Compensation Factor (P.C.F.) (default: 1/1, see PC). R = Reply: N= None, B = Bad, C<ch>= Try Channel <ch>, A= Aborted, J= Jammed. Note: This command is not valid for Gen2 (<sn> < 2,500,000). Program Compensation Factor PC[<sn>][,F<1|2>],<Num>[,|/]<Denom> [RA] {use RC command to verify} Where: RA = Programming Aborted. NOTE: Valid only for units with V9 code or later. Use RC or RS command to verify type and programming. PC can be any fraction where Num and Denom are integers from 1 to 255. By default it is 1/1 and on units before V9 the RC command will not show any factors. Program Reading PR[<sn>][,F<1|2>][, <count>] [RA] {use RM command to verify} Where: RA = Programming Aborted. Note1: If <sn> is Gen2 the S/W must prompt the user to use and remove the Programming Stick, before verifying the reading with an RM command. (RM won’t work if the Stick is still on) Note2: wild cards are not allowed when programming. If no <count>, 00000000 is assumed. Load Channel LC<ch> {none, URF>} Where <ch>=-25 to +15 (+ and leading 0 optional) Sets the Rcv frequency to that Channel Channel 0 = 415MHz and the channel spacing is 100KHz. At Power-on the default is Channel -5 (414.5MHz). When an RM, RS or RC command replies with “RC<ch>” send “LC<ch>” if you want to use this channel on the next interrogation (or to set it back to the default afterward) or record this channel in a data base for use on this SN next month.

Note: More information is displayed when the Expanded mode, “X+”, is active. (see COM2 spec.)
URFI HOST PROGRAMMING Universal RF Interrogator ? Host Programming Guide Page 16 AMCO Automated Systems • P/N 52845G125 Rev 1 FEB 2004 Purpose Command Response Group Mode G<+|->[,nn] [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. Antenna-switch A<E|I> Set the Antenna switch to External or Internal. (old MURFI only)
