TWACS System Overview
TWACS System Overview
The TWACS system is a fixed network, utility communication system. Running at
a centralized location, the TWACS operating software communicates with end
points, such as meters, by way of existing power lines. The TWACS system allows
full two-way access to and from the consumer’s meter, providing communication
and control features for the Utility.
The TWACS system consists of three levels of components (see Figure 1.1):
• Master Station (MS)
The Master Station TWACS operating software, either TWACS Net Server
(TNS) or TWACS® Network Gateway (TWACS NG), is the chief
component of the entire Two-Way Automatic Communication System
(TWACS). The Master Station software manages all collected metering and
interval data as well as the connection between the utility and the consumer’s
premises. TNS is DCSI’s standard solution while TWACS NG is available
for very large deployments requiring a high volume of readings for
time-of-use or critical peak pricing programs.
The primary functions of TNS and TWACS NG are:
•Managing the TWACS system communication network.
•Supporting applications such as metering, troubleshooting, outage
detection, and load control.
•Collecting remote meter data for the database server, which forwards the
data to a third-party utility software application.
TNS and TWACS NG are part of the corporate enterprise network. The
system is based on the Oracle® database, which is an open system, meaning
it can interact and inter-operate with other applications on local and remote
systems, on a variety of hardware platforms, and in a number of software
environments. The system provides the user interfaces for configuring the
necessary parameters to retrieve and send data.
• Substation Communications Equipment (SCE)
• Remote Communications Equipment (RCE)
This is the level at which the meter transponder resides within the electric
meter.
As shown in Figure 1.1, outbound messages originate in the Master Station and
pass through the substation to the transponder (RCE). Inbound meter data is sent
from the transponder to the SCE, where it is decoded and then sent to the Master
Station for analysis or bill file creation.

ESCRIPTION
This chapter provides a brief overview of the TWACS® - ORION® system,
explains how the TWACS® - ORION® system interfaces with the TWACS
system, and describes the functions of the EMTR-3, HHTR-3, and ORION®
transmitter.
System Overview
The TWACS® - ORION® system utilizes radio frequency (RF) transmission
communication between an RF-enabled auxiliary meter and an RF-enabled meter.
Data relative to energy usage from auxiliary gas, water, propane, or other
Intelligent End Device (IED) can be gathered and retrieved in this manner.
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-3; throughout this document EMTR-3
refers to both the EMTR-3 and EMTR-3-KV)
• Hand Held Transceiver (HHTR-3)
• Universal Metering Transponder (UMT; throughout this document UMT
refers to both the UMT-R-F MP and UMT-C-KV MP)
N
OTES
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.
Changes not expressly authorized by DCSI, Inc. could void the user’s authority
to operate the equipment.
10 TWACS®-ORION® for UMT Products User Guide
System Overview
RF communication links the ORION (located at the auxiliary meter) to the
EMTR-3 (located inside a nearby electric meter.) This communication enables
successful operation of the Automatic Meter Reading (AMR) system.
Figure 2.1
ORION transmitter and EMTR-3 transceiver
The TWACS® - ORION®system operates in the 902 - 928 MHz Industrial/
Scientific/Medical frequency band. The Badger ORION devices periodically
transmit bursts of digital data containing meter reading information on a frequency
of 916.45 MHz. These are one way transmissions, sent as a two millisecond burst
every four to five seconds, and are field strength limited under section 15.249 of
FCC regulations. The EMTR-3 devices are manufactured by DCSI and receive
transmissions from any ORION devices within range that have been assigned to
that EMTR-3. The EMTR-3 then passes the data to the UMT-R-F MP or
UMT-C-KV MP TWACS transponder. When requested by the utility, the meter
data is returned using the TWACS power line communications system.
The HHTR-3 is a tool used by an installer to set up and configure the EMTR-3 to
listen for transmissions from specific ORION devices. It also maintains a record of
installation activities which may be downloaded to a PC via hardware link at the
end of the day.
The following block diagram summarizes the interfaces and communications
between the system components.

System Overview
During the installation and configuration process, the HHTR-3 and EMTR-3 use
one or more of 51 channels spaced 322 kHz apart in the 902-928 MHz band to
intercommunicate with each other. Control commands and data are input to the
HHTR-3 via the keypad by the installation operator and passed to the EMTR-3
over the RF link. The EMTR-3 acknowledges transmissions from the HHTR-3 and
can read back internally stored data for confirmation of receipt. EMTR-3
transmission occurs only when data is sent or requested by the HHTR-3.
Frequency channel selection is controlled by the HHTR software and is not
operator selectable. Both the HHTR-3 and EMTR-3 operate as intentional
radiators under Section 15.249 of FCC regulations, with transmitted field strengths
limited to less than 94 dBuV/meter. These units use frequency shift-keyed digital
data at 9600 bps to communicate, and no subcarriers are used. The occupied
bandwidth of the EMTR-3 or HHTR-3 transmissions is 200 kHz. Both the
HHTR-3 and the EMTR-3 devices have permanently attached integral antennas
and use single integrated circuit RF transceivers.
Electric Meter Transceiver (EMTR-3)
The EMTR-3 is an electronic module assembly (EMA) that is installed in a
TWACS-enabled meter. The EMTR-3 is connected to the UMT transponder
during meter/transponder integration. The EMTR-3 adds functionality to the host
UMT. It does not communicate over the power line but provides data on-command
to the UMT when queried.
The EMTR-3 can communicate with up to seven ORION® transmitters. Data from
the ORION® transmitter is relayed to the EMTR-3 at each communication session.
This data is relayed upon request to the UMT via I2C communication and is
accessed by the TNS across the TWACS network.
The EMTR-3 listens (for 2.5 seconds) for communication from an ORION®
transmitter. Then, for 2.5 seconds the EMTR-3 listens for an HHTR-3. This pattern
cycles continuously.

RF Hardware Installation
This section provides instructions for installing the RF hardware on-site. 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-3 when performing the field
survey, such as:
• Metal objects
• Thick walls or foliage
• Local radio interference
• Position of the ORION and/or EMTR-3
Factor in all environmental conditions when planning the location of the
meter/EMTR-3 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-3.
16 TWACS®-ORION® for UMT Products User Guide
RF Hardware Installation
Environmental Conditions
Optimal RF communication between the ORION and the EMTR-3 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 Badger Meter, Inc. repeater or wired solution to ensure reliable
operation.
The following environmental factors or conditions may affect RF transmission
between the ORION® unit and the EMTR-3 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-3. 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 objects of interference are present.
TWACS®-ORION® for UMT Products User Guide 17
Chapter 2 • Functional Description
• Position of the ORION® and/or EMTR-3
These are important factors in RF deployment. The ORION® antenna is
omni-directional. The signal radiates 360 degrees. The EMTR-3 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-3 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.

The Electric Meter Transceiver 3 (EMTR-3) contains the equivalent of network
routing tables that must be maintained. The EMTR-3 maintains a routing table that
is built upon its port list, which reserves a given port for a given Intelligent End
Device (IED). The HHTR-3 can be used to manually create, modify, or remove
these port list assignments.
There are two options for inserting an IED into the EMTR-3’s port list: Listen
Mode and direct access to the Port List. Both options provide the same installation
with different aspects of the process being automated. Whether automated or
manual, the process gathers the IED serial number, service type, and desired port
location for installation.
The user must know the serial number of the EMTR-3 and manually enter it into
the HHTR-3 to establish a communication link with the EMTR-3.

Deployment Procedure
Deployment Procedure
The following procedure lists the steps required to deploy mulitport meters.
1. Install the electric meter epuipped with a TWACS module and an EMTR-3.
2. Install the ORION intelligent end device (IED).
3. Use the Listen List from the HHTR-3 to determine which ORION IEDs are
being heard by the selected EMTR-3.
4. Since the installer knows the ORION IED serial number, install the ORION
IED using the Listen List. If you hear nothing or obtain Error Code #33 (see
Error code descriptions and solutions on page 62) repeat this step.
5. If the ORION IED serial number is not in the Listen List, then program the
IED serial number into the ORION Connect ™ software in the Radix
handheld device. Listen for that particular serial number from a distance of
4-5 feet from the TWACS-equipped electric meter.
6. If you still cannot detect it, walk closer to the ORION IED to check if the
device is communicating.
7. If the ORION IED is heard within 4-5 feet of the EMTR-3 by the Radix
handheld device, but is not in the Listen List, check for another EMTR-3
within a clear line of sight and repeat the process.
N
OTES
This procedure is a recommendation, but it is not a requirement. Exact
installation procedures will be determined by the utility company and the
installers.
Multiple IEDs such as water, gas, or propane, do not need to be installed in any
particular order.
ORION water meters begin broadcasting when they detect a certain flow rate,
but ORION gas meters require installers to manually turn on the radio.
TWACS®-ORION® for UMT Products User Guide 57
CHAPTER
3
T
ROUBLESHOOTING
This chapter explains how to test and manage typical TWACS® ORION® system
problems. It is useful for installers and meter shop personnel. Foremost, it provides
diagnostic information through the TNS and TWACS NG systems which give you
a better assessment of problem conditions before field personnel are dispatched.
There are three essential sources of diagnostic information:
• The Intelligent End Device (IED) status, including leak detection, tamper
detection, and port assignment.
• Among the four bytes of total consumption readings are specific bits of data
for port-specific status information.
• The EMTR-3 diagnostic indicators.
Performing Remote Analysis (TNS)
Complete the following steps to determine if a field visit is required for an
unresponsive meter. You can end the procedure at any step and correct the problem
when a cause of failure is determined.
1. Check the AMRCOMMFAIL table for TWACS serial numbers that have
excessive AMR Communication Failure counts. This enables you to
identify meters that are consistently failing AMR.
If the meter fail count in the AMRCOMMFAIL table is equal to or greater
than the MaxFailCnt in the TNSDEFAULTS table, the Quality Code (QC)
will be set to RO (Retry Override). When the quality code is RO, the meter
unit map will have changed in the AMRCMDLST2WAY table. The meter
will be attempted the first time, but will not be issued subsequent retries and
must be read manually.
2. Determine if any error messages have occurred during AMR by checking
the SCE Notification log for any associated hardware issues for the meters
that are not communicating.
N
OTE
The Notification log contains important information about the status of
equipment and is automatically updated by TNS and the SCE. For detailed
information about the Notification log and error messages, see the
Notification Log section of the SCE Logs chapter in the TNS Operational
Process Guide and the Notification Log section in the SCE Maintenance chapter
of the TNS End User Guide.
58 TWACS®-ORION® for UMT Products User Guide
Performing Remote Analysis (TNS)
3. Check for TNS errors that may have occurred because of commands
time-out, or any software related issues in TNS that may have prevented
AMR commands processing.
For more information on time-out issues, see the Encode Command
Parameters section in the TNS System Maintenance chapter of the TNS End
User Guide.
4. Perform an On-Request AMR command to determine if the unit
communicates. (This command communicates to the unit by serial number
to eliminate a two-way addressing issue.)
For more information about On-Request meter reads, refer to the
appropriate sections in the TNS End User Guide and the TNS Operational
Process Guide.
A site visit is not required, and you may stop this procedure if the meter
communicates. If the meter communicates, check two-way addressing.
(For more information on two-way addressing, see the Function-Group
Addressing chapter of the TNS Operational Process Guide and the
Two-Way Addressing section in the TNS Generic Applications chapter of
the TNS End User Guide.)
5. Check for other TWACS meters that are reading on the same distribution
transformer, or a nearby meter to narrow the communication problem area.
6. Check the Customer Information System for a disconnected status that may
not have updated in the TNS database. If the meter was disconnected, no
action in TNS is required, but you may want to change the cycle number.
The TNS Operator must have some process for dealing with a meter that no
longer provides a read. The TNS Operator might consider setting up a
special cycle (e.g. cycle 99) for disconnects and continue reading the
meters. Having the disconnected meters in a special cycle allows the TNS
Operator to isolate meters to scan for usage. If a Customer Service
Representative re-activates the service and the notification fails to reach the
TNS Operator, or if a customer tampers with the meter and reconnects the
service, the TNS Operator can quickly identify a successful read in a group
of meters where reads should normally fail. Using this configuration, the
TNS Operator can quickly investigate the reason for the successful read of a
supposedly disconnected meter.
7. Check for switching events which may have occurred in the system that
possibly changed the communication path of the meter. (A communication
path may have changed due to a physical move or a temporary switch to a
different substation, phase, or other path component.) If the communication
path has changed, you can use Pathmaps to update the TNS database.
For more information on communication paths, see the Adding Meters
Interactively section in the Searching Meters chapter of the TNS
Operational Process Guide. For more information on Pathmaps, see the
Alternate Pathmaps Search chapter in the TNS End User Guide and the
Building and Searching Alternate Paths chapter in the TNS Operational
Process Guide.
TWACS®-ORION® for UMT Products User Guide 59
Chapter 3 • Troubleshooting
8. Check the Alternate Substation tables for up-to-date information on
Alternate Substations that can feed the primary sub.
For more information on Alternate Substation tables, see the Adding
Alternate Substation Information section in the SCE Maintenance chapter
of the TNS End User Guide. Also see the Alternate Substation Mapping and
Creating and Using Alternate Path Tables sections in the Building and
Searching Alternate Paths chapter of the TNS Operational Process Guide.
Port Specific Status Information
There is one byte within the Total Consumption reading (present or frozen) which
contains data that may be invaluable for diagnosing and troubleshooting issues
prior to rolling a truck.
Total Consumption (TC) registers (Present and Frozen Daily) on the EMTR-3
contain a three byte TC value and a one byte TC status. The Hour of Reading and
Configuration field in the TC status is used to establish a desired level of validity
for the TC reading. This five bit field also serves as a quick alternate method for
time stamping the data.
The Master Station (MS) has the capability to decide the quality of a TC reading
based on the Hour of Reading and Configuration field in the status byte of the
Total Consumption registers. TNS reflects the status of the TC reading in the TNS
field of the MIT On Request window.
Use the following procedure to access the MIT On Request window.
1. Follow the menu path Start > All Programs > TNS Metering Maintenance

Performing Remote Analysis (TWACS NG)
Complete the following steps to determine if a field visit is required for an
unresponsive meter. You can end the procedure at any step and correct the problem
when a cause of failure is determined.
1. If communication fails to the transponder, check the path and search state of
the transponder by following the path System Monitoring > Edit Path >
Search States.
2. Type in the serial number of the transponder and click Lookup.
If the transponder is currently in the New, Lost or Tentative path state, the
the TWACS NG will need to search the transponder. The TWACS NG
Operator will need to be sure that it is in a search state of Ready. The search
batch job should automatically pick up the transponder for search when the
next job runs.
3. If the transponder is in a Good/Done state, the TWACS NG Operator may
issue a ping to the transponder by following the path System Monitoring >
Test Transponder.
4. Type in the serial number or Meter/End Device ID and click Ping.
If the ping is successful, communication to the transponder is successful and
has been verified. If the transponder is still not functioning as expected, a
field visit will most likely be necessary.
5. The TWACS NG Operator may also want to check the notifications to
verify if any have been received for the transponder in question. For more
information regarding notifications, refer to the Notifications section of the
TWACS® Network Gateway Operational Process Guide.
6. If the previous steps determine that the meter has “Failed”, see Product
Returns on page 3 to return the meter.

Chapter 3 • Troubleshooting
Addressing Common Field Problems
Three problems often encountered in the field are: an EMTR-3 that doesn’t
communicate, an EMTR-3 that doesn’t knit, and an HHTR-3 unit that displays a
“time out” message. The following sections focus on these errors.
EMTR-3 Does Not Communicate
You must first determine whether or not the ORION® Intelligent End Device
(IED) is communicating. Verify this using the ORION Connect™ software in the
Radix handheld device or the drive-by device.
N
OTE
ORION water meters begin broadcasting when they detect a certain flow rate,
but ORION gas meters do not.
If the ORION is communicating, then you must determine if the EMTR-3 is
communicating. You can do this by taking a visual reading from the ORION
Intelligent End Device (IED) and comparing it to the EMTR-3 reading obtained
with the HHTR-3. If the readings are the same, the EMTR-3 is communicating. If
the readings are not the same, verify the serial number of the EMTR-3 is correct. If
it is, then place the HHTR-3 directly in front of the EMTR-3 to insure a clear radio
frequency (RF) link. If the EMTR-3 reading still does not match the reading on the
ORION, then check TNS. If the reading in TNS does not match the visual reading
taken from the ORION IED, you may need to make an adjustment in the Meter
Conversion table of TNS.
If the EMTR-3 reading does not match the reading on the ORION IED after these
steps, the EMTR-3 is not communicating. Call DCSI Customer Care.
EMTR-3 Does Not “Knit”
Knitting is the association of an EMTR-3 with an Intelligent End Device (IED).
This can be achieved using the Manage Listen Mode or the Manage Port List on
the HHTR-3. If you can access the Manage Listen Mode or the Manage Port List,
then the radio link between the EMTR-3 and the IED is good.
If you use the Listen List to associate an EMTR-3 with an IED and you get the
message “Install Unsuccessful” or “Install Unknown”, wait awhile and try again.
The EMTR-3 may not be able to hear the ORION at that moment.
If you use the Manage Port List to associate an EMTR-3 with an IED and you get
the message “Install Failed”, verify the serial number is correct. If you get the
message “Install Unknown” the EMTR-3 may not be able to hear the ORION at
that moment. Wait awhile and try again.

HHTR-3 Times Out
If the HHTR-3 times out, verify the EMTR-3 serial number is correct. If the
number is correct, place the HHTR-3 directly in front of the EMTR-3 to guarantee
a clear communication path, and try again. If the HHTR-3 continues to time out
after trying this, RF traffic may be exceptionally heavy, and the density is
preventing good communication. Wait awhile and try again. If the HHTR-3
continues to time out, there may be a problem with the HHTR-3 or EMTR-3
firmware. Call DCSI Customer Care.
Meter Shop Test System
Use the Meter Shop Test System to test TWACS signaling, read select transponder
registers, zero select transponder registers, and perform various other transponder
functions on a TWACS-enabled FOCUS meter. For complete details on the Meter
Shop Test System, see the Meter Shop Test System Help (accessed by clicking the
Help button on the Meter Shop Test Tool main menu) or contact your Program
Manager or DCSI Customer Care at care@twacs.com or 1-800-892-9008.
