2TWACS® - ORION® for CENTRON® Meter User GuideSystem OverviewSystem OverviewThe TWACS® - ORION® system utilizes radio frequency (RF) transmission communication between a RF-enabled auxiliary meter and a RF-enabled CENTRON® meter. Data relative to energy usage from auxiliary gas, water, or another electric meter can be gathered and retrieved in this manner. The system provides selectable Total Consumption data and Present Consumption data based on the hourly interval meter reading.Information is retrieved across the Two-Way Automatic Communication System (TWACS) network by the TWACS Net Server (TNS) located at the utility company. The TWACS® - ORION® system solution is comprised of the following RF devices:• Electric Meter Transceiver (EMTR)• Hand Held Transceiver (HHTR)• Electronic Metering Transponder (EMT-3C-MP)NOTEAlso part of the system, but not provided or installed by DCSI, is the Badger Meter, Inc. ORION transmitter that is installed at the auxiliary meter and converts the meter information into electronic signals.RF communication links the ORION (located at the auxiliary meter) to the EMTR (located inside a nearby electric meter.) This communication enables successful operation of the Automatic Meter Reading (AMR) system.

TWACS® - ORION® for CENTRON® Meter User Guide 3Installation and OperationTheory of OperationThe DCSI TWACS® - ORION® system operates within the 916.450 MHz UHF radio frequency range on channel 43A. This unlicensed frequency band is known as the ISM (Industrial, Science, and Medical) band. All components in the DCSI TWACS® - ORION®system comply with FCC (Federal Communications Commission) rules and regulations for radio devices operating in this frequency range.This band provides up to 79 channels; the TWACS® - ORION®system uses 51 of these channels. A channel is defined as a pair of adjacent frequencies used for transmission and for reception. Refer to the note below.Because the FCC limits the amount and duration of channel energy that can be emitted during RF transmission, the TWACS® - ORION® system employs transmission Frequency Shift Keying (FSK). This modulation and frequency hopping technology serves to: • Comply with FCC regulations• Reduce potential interference to and from other devices operating in the same band• Reduce the potential for eavesdropping• Minimize the effects of signal reduction NOTEFrequency hopping employs an algorithm that provides a half duplex (one transmission direction at a time [send or receive]), pseudo-random sequence of frequencies for the two-way radio link. Frequency Shift Keying modulation controls data transmission by “frequency shifting” between two frequencies (a channel). One frequency is used to represent the logical “1” and a different frequency represents the logical “0”.Five channels provide link acquisition with the HHTR while the remaining 45 channels are used for data transmission after a successful link is established. The one remaining channel is used for TWACS-ORION communication.The EMTR retains data until new data is uploaded during an ORION session. If an ORION transmitter is removed from the Remt List table stored in the EMTR, the previously loaded data (for the removed ORION transmitter) is automatically deleted.

4TWACS® - ORION® for CENTRON® Meter User GuideTheory of OperationElectric Meter Transceiver (EMTR)The EMTR is an electronic module assembly (EMA) that is installed in a TWACS-enabled CENTRON meter. The EMTR is connected to the EMT-3C-MP transponder during meter/transponder integration. The EMTR adds functionality to the host EMT-3C-MP. It does not communicate over the power line, but uploads the data to the EMT-3C-MP that has power line TWACS capabilities. The EMTR can communicate with up to four ORION transmitters. Data from the ORION transmitter is relayed to the EMA. This data is accessed by the TNS across the TWACS network.Near the top of the hour, the EMTR listens (for 12.5 seconds) for communication from an ORION transmitter. Then, for 8.5 seconds the EMTR listens for an HHTR. This pattern cycles 35 times. No further communication occurs until the next top of the hour. The top of the hour is set in TNS. Refer to Metering Maintenance in the TNS User Guide for instructions.Figure 1.1 Electric Meter Transceiver

TWACS® - ORION® for CENTRON® Meter User Guide 5Installation and OperationRF TWACS and Badger Meter, Inc. ORION® TransmitterThe DCSI RF TWACS System and the Badger Meter, Inc. ORION transmitter are capable of data communication. The ORION module uses the RF bubble-up broadcast mode to communicate (one way) from the auxiliary meter to the electric meter. The ORION transmitter sends customer usage data (at 100Kbps) every five seconds on the 916.450 MHz frequency channel. The RF TWACS system receives this data and transmits it to the EMTR. Then it is retrieved by the utility, across power distribution lines.Figure 1.2 ORION transmitters for water, gas, and remoteSpecifications:Table 1.1ORION transmitter specificationsREMOTEORIONGASORIONWATERORIONORIONSpecification DescriptionPower 3.6 VDC embedded batteryFunctional Life Expectancy Minimum: 10 yearsExpected: 15 yearsFrequency 916.450 MHzData Communications Burst mode fixed length packet, simplexData Format 3-of-6Data Rate 100 Kbps + 1 KbpsData Encryption NoneModulation Frequency Shift Keying (FSK)Packet Encoding Non Return to Zero (NRZ)Channels Single channel (43A)Range 400 ft. clear line of sight - affected by installation and conditions; less if pit installed

6TWACS® - ORION® for CENTRON® Meter User GuideTheory of OperationHand Held Transceiver (HHTR)The DCSI Hand Held Transceiver (HHTR) is used to configure and setup the EMTR (installed in the electric meter). The HHTR is also used to create the communication link between the EMTR and the ORION transmitter and can be used to test the radio link. Figure 1.3 Hand Held Transceiver keypad functions

TWACS® - ORION® for CENTRON® Meter User Guide 9Installation and OperationRF Hardware InstallationThis section provides instructions for installing the RF hardware onsite. A functioning network can be created and its functionality verified before leaving the site. Pre-Installation Field SurveyThe field survey is used to review the environmental conditions present at any particular location and lay out the system to maximize performance. DCSI recommends that you conduct a field survey before performing the actual hardware installation. As with all RF devices, certain environmental conditions must be present to optimize RF communications. Be aware of the factors that affect the radio transmission between the ORION and the EMTR when performing the field survey, such as:• Metal objects• Thick walls or foliage• Local radio interference• Position of the ORION and/or EMTRFactor in all environmental conditions when planning the location of the meter/EMTR assembly.NOTEA clear line of sight between the ORION transmitter and receiver is preferred, but is not always attainable.The following section discusses the environmental conditions that may affect RF transmissions between the ORION and EMTR. Environmental ConditionsOptimal RF communication between the ORION and the EMTR is affected by many environmental conditions. Vehicular traffic, parked vehicles in the signal path, weather conditions, construction, and even the growth of foliage may affect or degrade RF communication.Gradual loss of communication from the ORION (caused by an aging battery for example) can be detected through system checks by the TWACS Net Server (TNS) Master Station. Persistent loss of communication may indicate environmental interference and require a site visit to determine the cause. NOTESites that continue to experience persistent loss of communication may require a wired solution to ensure reliable operation.

10 TWACS® - ORION® for CENTRON® Meter User GuideRF Hardware InstallationThe following environmental factors or conditions may affect RF transmission between the ORION unit and the EMTR located at the electric meter. • Metal ObjectsMetal objects significantly reduce the strength of the signals reaching the receiver. Ensure that no metal cladding, cabling, mirrors, water tanks, refrigerators, pipes, etc. are near the ORION or EMTR. The straight-line path between both units should be as unobstructed as possible. NOTEA small, single item, such as a pipe situated half-way between the transmitter and receiver, is less likely to have any affect on the signal strength than a larger item(s). • Thick walls or foliageThick walls or foliage between the transmitter and receiver can reduce the signal strength. Brick, aluminum siding, thick stone walls, and concrete can impede signal reception.Avoid dense foliage between the RF units and, when possible, provide a reserve “growth” clearance to accommodate the growth of foliage on bushes and trees during spring and summer. NOTERadio signals can pass more easily through plasterboard walls, fiberglass, and wood paneling than the previously listed materials.• Local radio interferenceThe close proximity of a cell phone mast, a taxi operator's base station, or large electrical equipment may provide strong radio interference. The AMR radio devices should be relocated if these interferences are present.• Position of the ORION and/or EMTRThese are important factors in RF deployment. The ORION antenna is omni-directional. The signal radiates 360 degrees. The EMTR antenna alignment is parallel to the front cover of the electric meter, and is the most sensitive RF reception surface. Face the front of the meter/EMTR toward the ORION transmitter when possible; even on opposite sides of a building. This allows maximum communication surface and distance between the units. Allow for some additional power margin in the signal strength to accommodate seasonal or other changes in environmental conditions.In the future, after installation, the site owner should inform you of any alterations to the site that could affect radio performance.
