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-2)
• Hand Held Transceiver - Low Power (HHTR-LP)
• Electronic Metering Transponder (EMT-3C-MP)
N
OTE
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-2 (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 7
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
N
OTE
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-LP 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-2 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-2, the previously loaded data (for the removed ORION
transmitter) is automatically deleted.

8TWACS® - ORION® for CENTRON® Meter User Guide
Theory of Operation
Electric Meter Transceiver (EMTR-2)
The EMTR-2 is an electronic module assembly (EMA) that is installed in a
TWACS-enabled CENTRON meter. The EMTR-2 is connected to the
EMT-3C-MP transponder during meter/transponder integration. The
EMTR-2 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-2 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-2 listens (for 12.5 seconds) for
communication from an ORION transmitter. Then, for 8.5 seconds the
EMTR-2 listens for an HHTR-LP. 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.

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-2.
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-2 when performing the
field survey, such as:
• Metal objects
• Thick walls or foliage
• Local radio interference
• Position of the ORION and/or EMTR-2
Factor in all environmental conditions when planning the location of the
meter/EMTR-2 assembly.
N
OTE
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-2.
Environmental Conditions
Optimal RF communication between the ORION and the EMTR-2 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.
N
OTE
Sites that continue to experience persistent loss of communication may
require a wired solution to ensure reliable operation.
DRAFT
14 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-2 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-2. The
straight-line path between both units should be as unobstructed as
possible.
N
OTE
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.
N
OTE
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-2
These are important factors in RF deployment. The ORION antenna
is omni-directional. The signal radiates 360 degrees. The EMTR-2
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-2 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.

Troubleshooting and Error Messages
Troubleshooting and Error Messages
The following troubleshooting information can be used to determine the
cause of improper operation of the TWACS-ORION system.
TNS Troubleshooting
The TNS system can be used to check module and meter communication.
The TNS system includes error flags in returned messages that aid in issue
identification.
For error codes, refer to the Troubleshooting chapter in the TNS End User
Guide.
For information about TNS Trouble Server Applications, refer to the
Trouble Server Applications in the TNS End User Guide.
Field Troubleshooting
Distribution Control Systems, Inc. has developed various software and
hardware products for testing TWACS-enabled devices in the field and the
meter shop. See the Meter Shop Test System section of this chapter for
information regarding use of this system.
The EMTR-2 has no field serviceable parts. It can only install, delete, or
query installed ORION transmitters.
When necessary, the HHTR can be used to -
• Install the Orion transmitter (HHTR can not communicate with
Orion)
• Query the EMTR for a remote installed list
• Delete Orion from the EMTR installed list
• Check EMTR status (Hardware & Firmware version, and RCE Type
& Model)
A remote list query by the HHTR gives port-specific information for each
installed Orion transmitter as follows:
• Serial Number
• Present Total Consumption (not current total consumption, but rather
last RF communication total consumption, usually < 1 hr old)
• Leak Detect (tripped by water meter, will reset on its own, or can be
manually reset in the field; see the meter manufacturer
documentation for trip and reset conditions)
• Tamper Detect (must be field reset at water meter)
• RSSI (snapshot-from last check in)
• Acquisition Failures
