Chapter 1: System Overview 1 1 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 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). 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) to extract this data on demand. System Features FIREFLY AMR System Features

Data keys are the letter and number keys, A - Z and 0 - 9 . They are used to insert data into the ROADRUNNER. Function keys are labeled on the keyboard or the template. They are used to perform a special procedure or function. The SHIFT key shifts between the numeric and alphabetic keyboard on the Telxon 860ES and activates some of the function keys. Datamatic, Ltd. 2000 - 2003 Chapter 1: System Overview 3 Note: Under the column for the ROADRUNNER X7, the following keys: , ,

Telxon 860ES ROADRUNNER X7 Datamatic, Ltd. 2000 - 2003 Radio Frequency Receiving Unit (RFRU) Chapter 1: System Overview 7 The ROADRUNNER Radio Frequency Receiving Unit (RFRU) receives and buffers radio readings, then downloads them to the ROADRUNNER handheld unit when interrogated ("I" key). The ROADRUNNER RFRU is an integrated, internal unit, powered by a rechargeable NiCad battery pack. FCC ID: ODYD740 Datamatic, Ltd. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. WARNING: These devices operate under Part 15 of the FCC rules. Modifications to these devices not expressly authorized by Datamatic, Ltd. May affect your ability to legally operate these devices. Programming/Profiling Unit (PPU) The Programming/Profiling Unit
(PPU) is used to configure the MIUs, and to extract ProfilePlus historical reading information. The PPU creates a "positive snap"
interface with the MIU for hands-free operation, and when cabled to the ROADRUNNER handheld, enables communication. The PPU is powered with one 9-volt battery. Datamatic, Ltd. 2000 - 2003 8 FIREFLY AMR System Reference Manual Programming/Profiling Unit (PPU) Cable A cable is used to connect the PPU to a ROADRUNNER for programming and extraction of profile data. Config Tester (CT) The Config Tester (CT) is similar to the PPU. It is a stand-alone device for resetting the FIREFLY to dormant and factory configurations. Once coupled with the MIU and activated, there are three lights to display the status:
Yellow = Updating Green = Successful Red = Unsuccessful FIREFLY Meter Interface Unit (MIU) Water The FIREFLY Meter Interface Unit
(MIU) tracks and transmits reading data. Each MIU includes ProfilePlus that tracks and stores over 1,700 of the most recent readings. For example, the MIU can be configured to record 72+ days of hourly consumption readings, enabling the resolution of billing complaints. The FIREFLY signal includes the meter number, meter reading, battery voltage, tamper flag, and a leak indicator. The FIREFLY MIU is powered with a 3.6-volt lithium chloride D-cell battery. Material:

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.

Datamatic, Ltd. 2000 - 2003 10 FIREFLY AMR System Reference Manual Temperature Tolerance 300 degrees Electric FIREFLY MIU Meter Reading The Electric FIREFLY MIU unit counts disc rotations, which are typically 7.2 watt-
hours per rotation. The meter reading is stored in a 32-bit register in units of 0.1 watt-hours with a rollover at 99,999,999.9 watt-hours. The sensor constant, watt-hours per rotation, is set in the configuration data, and is typically initialized to 72 decimal (48 hexadecimal). The meter reading tracks the electric meter mechanical registers, this includes both forward and reverse rotations. That is, when the meter rotates forward, the meter reading goes up, and if the meter rotates in reverse direction, the electronics reading decreases just as the mechanical register decreases. The reverse rotation reading is also stored in a 32-bit register, which cumulates the reverse rotations in units of 0.1 watt-hours. This reverse rotation register increases only with reverse rotations; it never decreases. Demand Data Demand data is based on the change in the meter reading register over a demand interval. The demand interval is fixed to 15 minutes. The demand is recorded in units of kilowatts. Demand is only calculated on the net forward power for the interval. If there is net reverse consumption for the interval, then that interval is discarded. The peak demand of the current 30-day cycle that is in process and the peak demand of the previously completed 30-day cycle are stored. Profile Data The unit gathers and stores consumption profile data. The individual profile data elements are calculated from the change in the meter reading over the interval time, and then divided by the scale factor. The profile data is gathered according to configurable parameters, interval length, and scale factor. Valid values gathered range from + 32768 to 32767; positive and negative consumption is monitored. The data is stored in non-
volatile memory in a LIFO (Last In, First Out) manner. A total of 3,968 intervals are saved in the LIFO. The profile data is extracted from the optical port using the optical interface and handheld computer. Datamatic, Ltd. 2000 - 2003 Chapter 1: System Overview 11 Powering The unit is powered from the 240VAC line or through the battery connector with five to12-volts or both simultaneously. The current from the AC line has been limited to about 4 milliamps for safety considerations. Beware that the unit is not grounded, but is floating at the AC line potential. DO NOT TOUCH the electronics when connected to 240VAC. Also be aware that the resistors that connect to the AC line do heat up. Typically, a 1/4 to 1/2 watt is being dissipated continuously.
