M2 Utility Radio Transceiver Operations Manual OVERVIEW 1 INSTALLATION & WIRING 2 OPERATION 3 BATTERY 4 APPENDIX 5
1 OVERVIEW M2 Utility Radio Transmitter Basic Specifications Univeral The M1 radio is a universal AMR device designed for every utility. Encoder and digital inputs for all major water meter registers. Transmission: One-Way DTS Two-Way DTS (unregulated) Regulatory: FCC 15.247 Simple The M1 operates in an unlicensed mode in the 900-Mhz range which requires no utility regulation. The radio is easily configured and interfaced with an off-the-shelf PDA.
1 M2 Packaging The M2 is housed in a polycarbonate shell with multiple levels of waterproofing. The housing is available in either a clear or smoke tint. The housing is assembled with a UV-cure adhesive which provides the first level of environmental protection. The radio electronics are 100% encapsulated in a dielectric gel for 100% moisture protection. Finally, all cable entry/exit points are sealed with gel grommets to protect against longterm moisture penetration.
2 INSTALLATION & WIRING Installation The M2 is designed for all environments and can be installed either in indoor or outdoor environments. Mounting Orientation The most important consideration is to keep the M2 radio unit UPRIGHT when it is installed. The antenna is located on the top of the radio board and the RF transmission pattern is optimized with an upright orientation.
2 Pit & Vault Installations For best transmission, the unit should not be mounted directly on any metal surfaces, such as pipes or valves, or mounted below know water levels. The M1B has multiple mounting options, including a slot for wire ties which can be used to hang the M1A, attach on a plastic stake or screw directly onto a wall. An effective mounting technique for commercial meter vaults is to hang the M1A unit from a fixture (such as a ladder rung or the lid itself) near the top of the vault.
2 Indoor & Wall Installations For best transmission, the unit should not be mounted backing on metal surfaces, reinforced concrete or other dense surfaces. In indoor mounting situations, a higher mounting site will improve RF performance. In below grade sites (e.g. basements), the installer should experiment with the best location before the final mounting. In these instances, the direction/bearing of the receiver should be considered.
2 Wiring Encoders As a default communication The M2 utilizes the ECR-II communications defacto-standard wiring conventions for encoder interfaces: Red: Green: Black: Clock/PWR Data Ground This wiring convention should be consistent with all Metron-Farnier, ECR-II and ECR-III registers. The unit can be ordered with a prewired cable in 5-ft increments. In this case, the cable with leads will exit on the side or bottom of the unit.
2 Pulse Wiring For standard pulse wiring, the red and black wires should be connected to the pulse output of the register. Check the T2 wiring guide for color coding for most registers. Wire Connections The wiring connections are critical for reliable radio-to-register communications. T2 recommends the use of 3m gelcap type terminations. These connectors and the crimping tools are available at many hardware stores and online distributors.
2 Dual Enconder / Pulse Metron-Farnier offers a unique register that supplies a encoderoutput for meter reading purposes and a pulse output for datalogging purposes. This special-order unit will have multiple wiring connections: one for the encoder output and one for the switch closure output. Wire Connections The wiring connections are critical for reliable radio-to-register communications. T2 recommends the use of 3m gelcap type terminations.
3 OPERATION Operation The M2 radio operation is covered in five topics: • • • • • ON/OFF Control Configuration Meter Reading Datalogging RF Operations Refer to the FPDA, H2 and G2 Manuals for additional instructions on the operation of the M2 radio. This manual only provides an overview on these topics. ON/OFF Control If the M2 radio has been purchased as a separate unit, it will be shipped in the default setting. This will be in the OFF mode.
3 Configuration The M2 radio is a flexible unit with configuration options available for tailoring the unit for a specific utility’s needs. M2 Configuration Parameters Meter Settings Field PDA The configuration is performed by the T2 Field PDA (FPDA). Refer to the FPDA Manual for detailed instructions on the configuration process.
3 Meter Reading Local Data Access The M2 radio can be read locally via the FPDA or the H2 handheld.
3 Datalogging The M2 radio logs data as an enhanced data function. The basic data functions of the M2 radio – leak detection, backflow, high usage – are all detectable through the normal remote AMR operations (via the reading system). Data Logging PDA Screen The datalogging function offers a first-hand customer-service tool to examine the consumption pattern of a specific meter.
3 RF Operations - Normal AMR Reading The M2 radio transmits its RF signal on a regular interval (set by the transmit interval). The data is received by the R1 or R2 mobile AMR receiver. The R2 is a transceiver which provides the twoway capability for the G2 software.
4 BATTERY The M2 radio has a replaceable battery. Battery Specifications Mfg: Tekcell Type: Thionyl Lithium Chloride Size: D-cell Capacity: 19.5 A-hr Battery Life All battery calculations include a environmental impact factor and use a baseline of regular function usage (PDA reads, datalogging, etc.) The M2’s transmit period is directly related to the battery life of the M1 radio. The RF transmission is the largest power consumer and thus drives battery life.
4 Battery Replacement Transparent Technologies can provide replacement batteries for M2 radios. The battery is replaced by first removing the battery cover and then removing the battery cell. The battery is connected to the board with a quick disconnect plug. Some versions do not have a connector. In these cases, the battery wires can be cut and spliced with standard gecap connectors. The replacement battery will come with the identical plug.
6 APPENDIX FCC Information Information to user. - The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Special accessories. (a) Equipment marketed to a consumer must be capable of complying with the necessary regulations in the configuration in which the equipment is marketed.
6 FCC Definitions Class A digital device. A digital device that is marketed for use in a commercial, industrial or business environment, exclusive of a device which is marketed for use by the general public or is intended to be used in the home. Class B digital device. A digital device that is marketed for use in a residential environment notwithstanding use in commercial, business and industrial environments.
