This document describes how the units operates as a system and does not detail the specified limits or the performance. 5.1 Basic Components of Itron’s Submetering Network Itron, Inc. (“Itron”) is the manufacturer of remote utility meter reading products. Itron’s meter end point RF devices or PET modules encode consumption and tamper information, then transmit this data and other information via RF to the network PETRC units and/or the PET Repeater units. 5.1.1 PET Module The PET modules for water meters are self-contained low-power units, powered by long-life batteries. PET modules can be installed by the meter manufacturer during the manufacturing process or easily retrofitted into most existing meters. 5.1.2 Network PETRC and PET Repeater Units The network PETRC unit receives water usage data via RF from the PET modules, and transmits the data to the head-end MV-RS meter reading software via telephone or cellular telephone. Two types of units are utilized in the network: the PETRC unit and PET Repeater units. The base PETRC unit is similar to the PET Repeater unit except that it is equipped with a telephone connection. The telephone connection can be either a standard line or a cellular type. An optional cellular phone interconnect can be utilized on either a temporary or permanent basis depending on the application. As a temporary option, the varying lead time of telephone installation can be circumvented by utilizing the cellular phone interconnect option until a cost-
Installation Guide: PETNET System Components effective solution can be installed. In large scale roll-outs, often in areas large enough to span multiple telephone companies’ service territories, a single contact within one telephone company is often not available, which inevitably results in delays. With the cellular telephone option, these delays can be eliminated. Additionally, the cellular telephone option can be migrated from new installation to new installation as hard-wired telephone services are eventually installed at each site. The base PETRC unit is mounted at a central point in an apartment complex where ease of interconnection to power and telephone lines are available. This base unit can monitor and retain data on up to 1000 Water PET modules. Water usage data is gathered from the PET modules via a Frequency Hopping Spread Spectrum RF technology. Having the PET modules utilize a very slow “bubble up” rate minimizes the power consumption of the PET module, thus providing a much longer field life. The slow bubble up rate also minimizes unnecessary RF interference to other users in the RF band. The PET Repeater unit provides a store-and-forward functionality in the network. This unit receives PET module RF transmissions from surrounding PET modules, adds a time stamp, and upon a predetermined time, forwards the stored PET module data to other PETRC units (either through additional PET Repeater units or the base PETRC unit). Up to 7 levels can be configured in a string of PET Repeater units. Each level can communicate with all of the units at lower levels. Thus, the system can be configured to provide universal coverage in typical multi-dwelling or highrise environments. The ruggedized PETRC and PET Repeater units are capable of being mounted outside and is impervious to weather and potential vandalism. Water usage data transmitted by the network PETRC unit via telephone or cellular telephone is processed by the head-end MV-RS Meter Reading Software. The MV-RS system runs on a standard PC. MV-RS not only processes data received from network PETRC units, it provides an interactive, graphical user interface to allow users to extract and report key information. Itron’s MV-RS Meter Reading Software has been deployed throughout the world at over hundreds of locations. Originating within the utility market, this Multi-Vendor Reading Software has years of reliable service with millions of meters read. Itron has chosen the MV-RS Meter Reading Software, along with the network PETRC units and the PET modules, as key components in Itron’s PETNET Submetering Network because of their substantial history of reliable operations in the utility meter reading environment around the world.

PET Repeater Unit – Itron’s Network PET Repeater unit receives water, usage data via RF from the PET module, and sends the data to the PETRC unit. The PET Repeater unit operates similar to the PET in that it utilizes Frequency Hopping Spread Spectrum on a timed basis. The transmission are relatively short < 400ms and communicate up to 45 PET message per transmission. The PETRC unit synchronizes its receiver to the PET Repeater’s transmission following acquisition. The PET Repeater unit also provides an identification number with each transmission. The identification numbers of all PET Repeaters in the PETNET system are entered into the PETRC unit to allow reception into the system database. MV-RS Meter Reading Software - Water, Electric and Gas usage data sent by the network PETRC unit via telephone or cellular telephone is processed by the head-end MV-RS Meter Reading Software.

Installation Guide: PETNET System Components Figure 4 – Typical Mounting Location for the PET Repeater antenna
Installation Guide: PETNET System Components The PET Repeater antenna is typically mounted in an elevated unobstructed location in order to provide the maximum coverage between the PET modules as well as other repeaters and PETRC units. The antenna must be grounded utilizing a # 10 gauge solid core wire and suitable ground. In some cases a 6 foot grounding rod must be installed and connected to the #10 ground cable. This connection must be install such that it is weather resistant. Proper material is available at most electrical supply outlets. 7.0 Installation and Diagnostic Setup Once the PET modules and PETRC is installed, configuration and coverage testing can begin. The following paragraph desribe the set up procedure and configuration options. The data cable is connected to a PC running a copy of Procomm. This software communications package provides a number of features for displaying and capturing data for review. Identify which COM port is available on the PC and attach the Itron Inc. data cable. Tell Procomm which port is being used by assigning a direct connection to it and setting the communications parameters to 19200/N/8/1. Enter (lower case) ‘c’<enter> on the computer keyboard and observe the test computer’s display. An ‘R>’ should appear. Repeat the previous step if the ‘R>’ did not appear. Note: Occasionally the PETRC will ignore the communications port while it completes higher level tasks internally that are related to collecting and managing incoming PET data. It may be necessary to repeat the (lower case)’c’<enter> several times. Once the R> has appeared on the screen enter the following command: debug=y cexit<enter> Note: All of the console commands, with the exception of a few diagnostic commands are entered as lower case characters – be sure the CAPS Lock is ‘OFF’. At this time the display should be filling with information related to the tracking and processing of PET data. The PETRC uses several different colors for different kinds of information displayed. The reverse video lines of information relate to the ‘Large Block’ forwarding process. If the equipment does not respond to keyboard requests check the following: CAPS Lock (must be ‘OFF’, entries are in lower case) Data cable from PETRC to test computer Computer COM ports and COM port setup in Procomm 8.0 Console Commands This section describes the commands available from the console mode. These commands are readily available to the operator that has connected a remote computer, normally running
Installation Guide: PETNET System Components ProComm software, to the PETRC’s serial port. The method of connection can be either via modem or directly coupled with the appropriate data cable supplied by Itron Inc.. Note: All console commands are entered in lower case, be sure CAPS LOCK is off. The following commands are listed in alphabetically order: blist Lists all of the active PETs in the PETRC database at once. The data is intended to be captured by a remote computer program like the data capture feature in Procomm. cexit The correct way to exit ‘console’ mode is to enter cexit. This allows information to be saved in memory properly and begin the unattended application mode. clear This clears the PET database without clearing the arrivals list. This allows the operator to quickly collect new PET readings since the PETRC does not have to reacquire the PET timing and channel again. clearp This command clears the PET database and the arrivals list. All PET information must now be re-acquired again. chclr Chclr will clear the channel count data. To view the data before clearing enter ‘cview’. clbat Clbat clears the low battery flag on all of the PETs stored in the PETRC database. clist Clist counts all of the active PETs in the database and reports the number. commd Commd allows the operator to turn off port diagnostic information that appears on the screen. commd=1, eliminates extra characters commd=0, allows extra characters cview Cview displays the number of successful packets received on each of the 25 receiver channels. dbtim Dbtim sets the amount of time that the PET will reside in the database without being refreshed. debug Debug is a mode of operation that will send additional messages to the screen while the system is tracking and acquiring data. This mode is used for test. delay Delay allows the operator to increase the delay time before a packet is retransmitted. displ Displ limits the amount of debug data that is presented on the display. displ=1 for terse messages displ=0 for verbose or traditional messages
Installation Guide: PETNET System Components dlist Dlist will list the PETs that are active in the database along with associated packet information. elist Elist will list the PETs that are active in the database – 3 column format, screen at a time. gohop Gohop allows the operator to override the random number generator for the first large block transmission frequency. The local transmitting Class 1 PETRC will initiate its hopping sequence with the gohop value entered. The hopping sequence is tied to the serial number, however, the starting hop is redirected. gohop=24 for causing the first transmission to utilize frequency 926.1Mhz lbint Lbint sets the repeat interval for sending pre-emptive large block transmissions. lwbat Lwbat will reset all of the PETs low battery flag that reside in the PETRC’s database. pchnl Pchnl sets the acquisition channel that the receiver will utilize when in acquisition mode. pdump Pdump will display the PET tracking information on the screen and then return the system immediately to automatic unattended operation. plist Plist displays the operating parameters that deal with PET tracking and database management. Optional commands for shorter lists are: plist1, plist2 and plist3. ptime Ptime sets the PET receive interval time, normally set to 600 seconds which equals 10 minutes. rptcl Rptcl allows the operator to set the repeater class of operation. rptcl=0 would establish the local PETRC as a base unit rptcl=1 would establish the local PETRC as a repeater rxtim Rxtim sets the amount of time that the PET will remain active in the database without being updated by a more recent transmission. rdiag Rdiag allows the operator to select the low level diagnostic mode of operation. This mode is used for testing the PETRC on the test bench. rxwin Rxwin sets the window size for tracking PET transmissions. modem Modem allows the operator to edit the modem initialization string. slist Slist Allows the operator to request information on a single PET in the local PETRC’s database. snchg Snchg is used to enter the local PETRC’s serial number into protected memory. snchg=1202354 sets serial number 1202354 into protected memory
Installation Guide: PETNET System Components snrp1 Snrp1 sets the first serial number in the allowable large block repeater ID list. snrp2 Snrp2 sets the second serial number in the allowable large block repeater ID list. snrp3 Snrp3 sets the third serial number in the allowable large block repeater ID list. snrp4 Snrp4 sets the fourth serial number in the allowable large block repeater ID list. track Track displays tracking statistics for (maximum 4 Ea.) large block repeaters. Note: All commands are 5 characters in length and are lower case. 9.0 Troubleshooting the PETNET Submetering Components If you have difficulties with overall system operation this generally indicates a PETRC unit problem.
