System Overview
System Overview
The 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)
NOTE
Also 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)

Installation and Operation
Theory of Operation
The 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
NOTE
Frequency 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.
TWACS® - ORION® for CENTRON® Meter User Guide
Theory of Operation
Electric 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.

Installation and Operation
RF TWACS and Badger Meter, Inc. ORION® Transmitter
The 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.

Installation and Operation
RF Hardware Installation
This 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 Survey
The 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 EMTR
Factor in all environmental conditions when planning the location of the
meter/EMTR assembly.
NOTE
A 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 Conditions
Optimal 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.
NOTE
Sites that continue to experience persistent loss of communication may
require a wired solution to ensure reliable operation.
TWACS® - ORION® for CENTRON® Meter User Guide
RF Hardware Installation
The following environmental factors or conditions may affect RF
transmission between the ORION unit and the EMTR located at the electric
meter.
• Metal Objects
Metal 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.
NOTE
A 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 foliage
Thick 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.
NOTE
Radio signals can pass more easily through plasterboard walls,
fiberglass, and wood paneling than the previously listed materials.
• Local radio interference
The 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 EMTR
These 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.

Two important conditions apply to this procedure:
1.
NOTE
The existing EMTR must be able to communicate with the ORION for
the Remt List to be downloaded to the HHTR, to simplify reinstalling
applicable ORIONs.
If communication is not possible, this procedure can not be performed.
Replace the existing meter according to your utility procedures, and
perform Install the ORION (Linking the ORION and EMTR) on page 13 to
install the individual ORIONs.
2.
This procedure requires the physical removal of the existing installed
meter and installation of a replacement meter/EMTR combination.
Perform the following procedure to replace an EMTR.
If you pressed the HHTR On/Off button at the end of any previous procedure,
begin with step 1.

Field Troubleshooting
The most likely field troubleshooting scenario is a failure of the power up
LED to flash. If the LED on theTWACS-ORION system is not flashing,
ensure that the TWACS-enabled meter is receiving the appropriate power
according to its specific form and voltage (refer to Installation on page 21).
You may use a Remote Test Set (RTS) for further testing or return the meter
to the Meter Shop for further diagnostics.
