INTRODUCTION
Thank you for your purchase of our Rivet Counter ET-44 locomotive. In this
booklet you will nd information in regards to maintenance, lubrication, body
removal, storage and basic DCC instructions. For additional information, part
numbers, and exploded drawings, please see our website: www.scaletrains.com.
If you have purchased a Sound and DCC Equipped model, then you will have
access to all the features of this outstanding locomotive. For those that have
purchased the DCC and Sound Ready version, the DCC information contianed
in this manual will not be applicable to your model. All of our models are
equipped with a 21 pin MTC receptacle should you decide to install DCC at a
later date. Our ET-44 should accept any 21 pin DCC decoder.
One new and exciting feature of your new Rivet Counter ET-44 is that it has
the latest version of ESU software installed which includes the “Full Throttle”
feature. This allows even more realistic locomotive operation. We recommend
that you download the “Full Throttle” Quick Start Guide and the full decoder
manual from the ESU webiste to learn all about this new feature and other
features of ESU decoders. Visit www.LokSound.com for more information.
Our DCC and Sound Equipped ET-44 locomotive model is tted with the ESU
LokSound™ V5 DCC decoder (ESU #58429) full-function decoder. For more
information and to download the decoder technical manual, visit the ESU
website listed above. The manual document number is 51989.
For those purchasing a DCC and Sound Ready locomomitve and wishing
to install sound at a later time, the same decoder may be used. If you wish
to install a non-sound decoder, ScaleTrains.com™ recommends the ESU
LokPilot™ # 59629. When choosing a decoder for a DCC and Sound Ready
unit it is important to remember that ONLY ESU decoders will have access to
all of the advanced lighting features of our Rivet Counter™ locomotives and
the Power Pack™ circuit. Please contact our sales department for assistance
in selecting the proper decoder and programming for your operation. The
manual for the non-sound, LokPilot decoder is document number 51986.
Either choice will allow you to get the most out of the sound or lighting
functions designed for your locomotive. Please see the section “Something
New” for more information on installing decoders.
Your state-of-the-art locomotive model is designed to utilize either two
sugar cube type speakers, 11mm x 15mm, in the included custom enclosure
and wired in parallel back to the main board or a 16 mm x 35 oval speaker
mounted directly into the die-cast frame in place of the enclosure for the
smaller speaker pair.
IMPORTANT NOTE: Other brand 21-pin decoders may t, however, they will
not have access to certain electronic components on the main board that
control some lighting functions and the Power Pack circuit.
THE PROTOTYPE
Designed by EMD with the help of General Motors’ Automotive Styling Center,
948 total ET-44 locomotives were built between 1961 and 1963. The 2250hp
turbocharged locomotives competed directly with General Electric’s U25
Series. They featured numerous upgrades including a centralized air system
with an inertial air intake and ltration system that provided clean pressurized
air to the locomotive. The taller electrical cabinet, combined with the styling
input from GM, created a “humpback” that was instantly recognizable. Later
in their careers, many ET-44s were rebuilt by their owners which extended the
lives of the remaining units for decades to come.

THE MODEL
Your ScaleTrains ET-44 model is a meticulously designed and crafted model
to match the prototype. DCC and Sound equipped ET-44 models include an
on-board sound system, featuring speakers designed to replicate the roar
of the prototype. Also included are sounds for the horn, bell, and various
auxillary systems.
HANDLING
Due to the delicate nature of the model, it is advised that care should be taken
when removing the model from its packaging and when placing it on the track
to operate or test.
REMOVAL FROM PACKAGING
To remove the locomotive, carefully slide off the outer sleeve from the
“clamshell”plastic holder cradling the model and set it aside.
Next, unsnap the plastic clamshell holder; note that one end is hinged and
designed to snap into the top half of the holder. Do this on a at surface to
reduce the risk of the calmshell, or the model, from slipping from your grip
and falling to the oor. Once the clamshell is fully open, carefullly remove the
model; reverse the proceedure for storing the locomotive.
STORING YOUR MODEL
If you choose to store your model in its box, pay close attention to the model’s
orientation as you place it in the clamshell container. The model will only t
correctly one way (the nose toward the clamshell hinge). Improper placement
may result in damage to small detail parts or railings on the model. Damage
due to improper storage is not covered under the manufacturer’s warranty.
When handling the model, it is recommended to grip the model rmly at its
mid-section and around the fuel tank while avoiding the ne details on the
model that may be present.
DISASSEMBLY
When disassembing the locomotive, it is recommended that it be placed
upside-down into a foam cradle to protect it from damage. In order to remove
the body, simply remove the coupler box screws, couplers and coupler boxes.
Once the screws and coupler boxes are removed, the body shell can now be
removed from the mechanism. Pay particular attention to the possibility of
wires or other connections between the body and chassis. Gently lifting up
on the body, while paying close attention to small details, should allow the
body to be easily removed as only friction is holding it in place. To install crew
gures in the cab, gently disconnect any handrails connected to the cab. There
is a tab at the top rear of the cab where it connects to the long hood. Once
the handrails are detached, the cab can lift up vertically. This will take a small
amount of force to pop the tab loose to allow the cab to come up. Reassemble
the model in the reverse order.
NOTE: If there are conduit pipes or other details that cross the separation
between the cab and engine hood, the cab may not be removed without
damage to these details.
CLEANING
If kept out of its protective packaging for extended periods, it is likely your ET-
44 may accumulate dust or other debris. While unsightly, it can also potentially
damage the nish of the model if allowed to accumulate. To remove light
dust, it is recommended that a ne paint brush be used to gently knock off
dust particles. For heavier accumulations, canned air dusters (commonly used
for cleaning electronics), or air from an airbrush, can be used. Use care with
compressed air so as to not dislodge small detail parts.

LUBRICATION
The ScaleTrains ES44 locomotive represents hours of careful research and
design work, and we are proud to present it to you. With the right care, it should
provide years and years of model railroading enjoyment. Out of the box, the
model should be ready for service, no lubrication should be necessary; it has
been carefully lubricated at the factory for optimum performance. If the need to
lubricate should arise, please follow these guidelines:
• Be sure to use a plastic-compatible lubricant! Most household
lubricants, such as “3-in-1” type oils, may damage the slippery
engineering plastic found in the driveline of the model. Wherever
possible, use lubricants designed specically for model railroad
or similar hobby uses, and if in doubt, check the label for any
compatibility warnings.
• Use the right type of lubricant in the right location! For metal-to-metal
bearing surfaces, the use of light or medium oils is recommended.
For plastic-to-plastic applications, such as gears, light greases are
recommended.
• Always use lubricant sparingly! As the saying goes, a little goes a long
way. When applying lubricant to bearing surfaces, a tiny drop or dab
applied with a ne point, such as a tootpick, should be more than
sufcient. Any excess lubricant oozing from a bearing surface should
be carefully wiped away with a paper towel. Excess lubricant that
migrates onto electrical pickups can impede power and DCC signal
pickup and lead to erratic operation.
Lubrication points will be the same as would be expected in most any model
locomotive. On the locomotive power trucks, the bearing is behind the wheel
so a small drop of light plastic compatible oil can be used behind each wheel
as necessary.
The interior of the model is lled with circuit boards and wiring for the
many features of your ES44 locomotive, so great care must be taken when
applying lubrication to areas that may require it inside the locomotive. Refer
to the disassembly instructions and exploded diagrams to understand how
to remove the body to access the inner workings of the locomoitve. This
information may be included with the model or available on our website.
Lubrication points inside the locomotive would be the motor bearings, where
a small drop of oil between the motor ends and brass ywheels, on the motor
shaft, will be sufcient. The other location would be at the worm shafts on
the top of the gearboxes. These too can use a small drop of oil at both ends
of the shaft. One end being where the driveshafts are attached to the metal
worm shaft and the other being the opposite end where the shaft slightly
protrudes out of the outermost bearing. Grease can be applied to the gear
box by removing the worm cover and then the worm and shaft. Once the
worm and shaft are removed, a small amount of grease can be applied to the
top gear box gear: the one that contacts the worm gear, then the worm and
worm cover can be reinstalled. As the locomotive runs, the grease will be
distributed inside the gearbox to all the gears.
Whenever possible, avoid contact of the lubricant to the model’s exterior
nish. Oils and greases can harm the factory paint and lettering. Any excess
that may make contact should be gently wiped away with a paper towel or
other ne cloth.
Due to the delicate nature of the interior components inside the locomotives,
if there is any concern, it may be best to contact your local dealer or contact
us directly to help guide you through the lubrication process. Our support
team is available by email at: [e-mail].

OPERATING ON DC
DCC & SOUND READY MODELS
DCC & Sound Ready models are equipped with a blind plug (dummy plug)
that allows the model to operate on a DC powered track right out of the box.
No modication is necessary.
When operating a DCC & Sound Ready model, you will have directional
headlights, White only classication lights (if equipped) and either number
board or front ditch lights, but not both. Rear ditch lights (if equipped) will not
operate on DC power unless the rear of the locomotive is designated as front
by railroad practice.
DCC & SOUND EQUIPPED MODELS
DCC & Sound Equipped models are equipped with an ESU LokSound V5
DCC decoder that will allow operation on a DC powered track once sufcient
electrical power is supplied. The Start Up Cycle will begin with the turnover of
the engine prime mover sound. Once the Start Up Cycle has completed, the
throttle may be advanced to move the locomotive.
DC OPERATION NOTE: Small train set power packs and some low output DC
power packs may be able to supply enough voltage/current to activate the
start up sound but lack the output capacity to cause the model to move. If this
condition occurs, there is no cause for alarm, however, a different, higher output
power supply should be used that does not exceed the input capacity of the
decoder. See ESU decoder manual for details on power requirements.
Sound equipped models operating on DC will only have the prime mover sound
that will increase through the notches as power is applied with the DC supply.
DCC functions that are autonomically controlled on DC and that will be on are
the front and rear headlights (directional), number boards, walkway lights (if
equipped) and front ditch lights. Rear ditch lights will not operate nor will other
sounds like the horn, bell, air compressor, etc. These sounds may only be user
controlled when operating on DCC.
OPERATING ON DCC
DCC & SOUND READY MODELS
DCC & Sound Ready models contain sensitive electronics and should not be
operated on a DCC controlled track even, if the DCC system is capable of
doing so. DCC isn’t A/C or DC, it is both! Confusing, to some degree, but it is
a bi-polar, square wave, DC signal or alternating DC. Operating a DCC Ready
model without a decoder install on DCC causes the motor to buzz because it
is alternating direction at the frequency of the DCC signal. This isn’t good for
the motor as it will heat up rapidly and could cause damage over time.
DCC & SOUND EQUIPPED MODELS
Operating your new model on DCC is the best way to get the most
enjoyment out of all the state-of-the-art features that are built into the model
whether yours is factory sound equipped or you have chosen to install a non-
sound decoder. The rst question in either case is:“How do I get started?”
In this manual, we will be providing DCC instructions for factory sound
equipped models.
GETTING STARTED
ScaleTrains.com models begin with the sound off when you rst put the
locomotive on the track and may be addressed initially using DCC address: 3.
On DCC, pressing F8 will initiate the Start Up cycle. The Start Up cycle for
your new ES44 locomotive is one of the most realistic in the hobby to date!
During Start Up, the locomotive may not be moved until the cycle completes
and the locomotive’s prime mover sound settles down to an idling state.
This can take from 40 seconds to one minute depending on the length of
the recorded start cycle. Start Delay can be disabled by setting CV124 = 0
(default = 4). If you wish for the Start-Up cycle to begin when track power is
applied, change the following CV settings in order:
CV31 = 16, CV32 = 3
-----------------------------
CV419 = 32
CV435 = 32
CV451 = 32
CV467 = 32
CV31 = 16, CV32 = 4
-----------------------------
CV307 = 32
CV339 = 16

6 7
ADDING A DECODER
There is no better way to get the most from your model than to operate using
DCC. An ESU DCC decoder allows you to access all of the lighting outputs
built into your model. If you are installing a sound decoder, you will have the
most realistic model available today!
Due to the many lighting features that our Rivet Counter ES44 is equipped
with, we have employed two DIP switches on the main circuit board. These
help with the DCC functionality of the lighting features. If your Rivet Counter
model has factory sound, or you are installing an ESU sound or non-sound
decoder, these DIP switches are to be turned OFF ( see Fig.1 ) to help with
the lighting effects and only when using an ESU brand decoder (DCC &
Sound Ready units come with the DIP switches in the on position). If you
choose to use a different brand decoder, the DIP switches should be in
the ON position. Important Note: non-ESU decoders will only have partial
access to the advanced lighting effects and will not be able to control the
Power Pack that is part of the main board. When using non-ESU decoders,
you will have directional headlights, lighted number boards and white class
lights (if equipped). Red and green class lights will not function with non-ESU
decoders the same as when operating on DC power.
Fig.1
Note: For non-sound Lokpilot installs: Units equipped with class lights (if
equipped) will not be able to cycle through the various colors using F5 as
you can with a Loksound decoder. When using a Lokpilot decoder, three
functions buttons are used to control the class lights. Check the Function Map
Chart to see how F5 is used on your model.
SOUND VOLUME ADJUSTMENTS
MASTER VOLUME CONTROL CV63
When operating your model it may be desirable to adjust the sound volume
differently than programmed at the factory. Only one CV is necessary to
adjust the Master Volume Control. CV63 moves all sound up or down
depending on the setting. The ESU V5 DCC decoder will allow adjustments
from 0 to 150%. The factory setting will vary depending on the model. You
can read CV63 with your DCC system’s program track to learn the default
value for your model before making any adjustments. Volume settings from 0
to 128 are 0 to 100%. Settings from 129 to 192 are 101 to 150%.
Important Note: Settings between 129 and 160 (125%) are generally safe.
Settings above 160 should be used with caution especially with single or small
speaker installations to keep from over driving and damaging your speakers.
INDIVIDUAL SOUNDS / VOLUME CONTROL
The advanced functions of the ESU Loksound V5 decoder allows you to
control the volume on each sound loaded in the decoder separately in
addition to the master volume. Confusing? Not really. Think of your decoder
like the mixing board of an event hall or concert venue. In these setups, you
can control the input of each microphone, instrument, etc. to mix them and
come up with the compostion you want. Your ESU decoder does the same
with the individual input volumes for each sound and then the master volume
to move all sound up or down at the same percentage while keeping the
sound mix the same.
To control so many sounds on a single decoder, ESU has utilized CVs above
the normal cap of 255 by indexing the CV. Indexing can be a complicated
subject but to simplfy it, you must use three CVs to set the volume of an
individual sound CV. We will use CV31, CV32 and the CV for the sound slot’s
volume (see Sound CV chart).
Important Note: The following CVs MUST be set rst before adjusting the
sound slot volume: CV31 =16 and CV32 = 1.

6 7
SOUND SLOT VOLUME CHART
Below are the individual sounds for your locomotive and the CVs that control
the volumes. Remember, before adjusting these CVs, you MUST set CV31 =
16 and CV32 = 1. Failure to set these rst will result in the decoder ignoring
your command or you will program something unintentionally.
MUST rst set CV31 = 16 and CV32 = 1 to adjust slot volumes 1 to 32

BASIC DCC FUNCTIONS
F0 HEADLIGHTS
Like most models, in DCC, F0 will illuminate the headlight in the direction
of travel, forward or backward. You may dim either light by pressing F12.
Please note that headlights are only illuminated in the direction of travel. In
DC operation, the headlights are illuminated automatically and directionally
controlled and are on all the time if sufcient power is applied to the track.
F4 DYNAMIC BRAKES
For ET-44s that have dynamic brakes, the function will be as with any other
dynamic brake-equipped Scaletrains locomotive. However, some ET-44s
are not equipped with dynamic brake. When a non-dynamic brake loco is
consisted behind a dynamic brake-equipped loco, the non-dynamic brake
loco will drop the prime mover to idle and hold. We’ve now implemented
this realistic feature into your new ET-44 locomotives! If F4 is pressed on a
dynamic brake equipped version, it will go through its normal DB cycle. If F4
is pressed on the non-dynamic brake version it will drop to Idle and hold until
it is turned off.
F5 DPU LIGHTS
The ET-44 is equipped with a DPU (Distributed Power Unit) light function for
operating on the rear of a train in DPU-Pusher service. As required under
U.S.C. Title 49, this function (F5), when activated, will extinguish the head and
ditch lights in the leading direction and illuminate the headlight in the trailing
direction at reduced brightness. This feature is to mark the rear of the train. To
return the lighting to normal operation, press F5 again to toggle this function
off. NOTE: Canadian National model have a separate red light on the right
rear and left front that are illuminated in addition to the rear headlight.
NOTE: DPU light function will not operate during DC operation.
F6 DITCH LIGHTS
Some ET-44s are equipped with working front and rear ditch lights (based
on the prototype). Also, some will have ditch lights that ash when the horn
is blown. Some modelers may prefer to change the ditch lights to their
preference. The CVs below will allow you to congure them to suite your
operating preference.
NOTE: Ditch lights will only function in DCC operation.
F9 DRIVE HOLD
The Drive Hold feature allows one to separate the motor control from the
throttle sounds. By toggling F9 on, the speed of the loco will be locked at
teh current speed step. Subsequent throttle movement will either speed
up or slow down the prime mover sound but will not affect the speed. To
discontinue use of Drive Hold, toggle F9 off.
F10 INDEPENDENT BRAKE
Activating F10 will initiate the brake function and cause the locomotive to
come to a stop in accordance with the setting endter in Brake 1 (CV179.)
Once the locomotive is stopped, the prime mover may be throttled up or
down but the locomotive will not move. Toggle F10 OFF to release the brakes
and continue on.
F12 HEADLIGHT DIMMER
By toggling F12 to the ON position, the headlight will be reduced to
approximately 50% brightness and the ditchlights in the directin of travel will
be turned off. To reverse this and return the headlight to full brightness with
ditchlights on, toggle F12 OFF.
For Flashing Ditch Lights:
CV31=16, CV32=8
---------------------
CV373=4, CV389=4
For Non-Flashing Ditch Lights:
CV31=16, CV32=8
---------------------
CV373=0, CV389=0

10 11
BASIC DCC FUNCTIONS (continued)
GROUND LIGHTS and WALKWAY LIGHTS
The ET-44 is equipped with lighted walkway lights and ground lights to match
the prototype railroad’s practice. These lights are automatically controlled
and come on during the Start Up cycle when F8 is pressed. They will go off
during the shutdown sequence when F8 is pressed to shut the locomotive
down. NOTE: If F8 is used to mute the sound during operation these lights
will be turned off until the sound is unmuted with F8.
ESU POWER PACK
Rivet Counter models come equipped with an ESU Power Pack energy
storage device built into the locomotive. These Power Pack devices will
work as a backup if the model looses power for a short period of time. If
your model is factory equipped with a Loksound decoder, if one is installed
later, or if you install a Lokpilot decoder, you will be able to utilize the Power
Pack circuit in your Rivet Counter ET-44 model. Non-ESU decoders cannot
control the Power Pack and it does not function on DC power or in DCC &
Sound Ready models that do not have an ESU decoder installed and properly
congured. Please remember, a Power Pack is a backup, not a battery. This is
not an excuse to never clean your track again! They must be charged using
track power to function and need track power to stay charged.
The time in which the caps bridge a power loss is adjusted by using CV113.
The default setting on most models is 32. This can be adjusted up or down.

10 11
BASIC PROGRAMMING NOTES
DCC & SOUND EQUIPPED MODELS
Customizing the programming in your DCC & Sound Equipped model is yet
another way to get more enjoyment from your investment. With a few basic
guidelines, customizing can be easily done. You may also wish to have the
manual for your DCC system handy as well in case a refresher is necessary.
It is recommended that you use Paged Mode programming to adjust
CV settings on your DCC system’s programming track. While this is the
recommended mode, Direct Mode may also be used and in many cases,
except a decoder reset, some adjustments can be made with Programming
on the Main (i.e. address programming, master volume change, horn or
bell choice, etc). An auxilliary programming track booster is not necessary
to program an ESU decoder and can interfere with programming in some
instances. DCC CVs cannot be adjusted if you are operating your DCC &
Sound Equipped model on a DC powered track.
If you will operate your ET-44 on DCC, it is recommended that you download,
read and understand the appropriate Loksound decoder manual for the
decoder in use in your model. The V5 manual is document # 51989 on the
ESU download webpage at www.LokSound.com and is correct for all DCC &
Sound Equipped models produced after January 2019.
DIGITRAX CV PROGRAMMING FOR CVs OVER 255
Some older Digitrax DCC systems do not allow programming of CVs above
255. In order to make full programming possible, we have implemented
an assistance tool. This helps to write the number of the CVs desired
temporarily into two assisting CVs (so-called address registers), since the
usual CVs cannot be reached. Afterwards, the value of the CV desired will
be programmed into another assisting CV (value register). When the value
register is written, the content will be copied to the actual desired position
and the assisting CV will be set back. Consequently, 3 CVs have to be
programmed to write one CV. These three CVs are described in the following
text:
CV96 - Name Offset CV - Saves the CV number that should be actually
programmed in hundreds. Value Range: 0 to 9.
CV97 - Address CV - Saves the CV number that should be actually
programmed in units of tens. Value Range: 0 to 99.
CV99 - Value CV - Saves the value of the CV that should be actually
programmed. Value Range: 0 to 255.
Example: Need to program CV317 to value of 120.
Program the value of the CV number in hundreds into CV96.
In this example: CV96 = 3
Program the value of the CV number in tens and ones into CV97.
In this example: CV97 = 17
Program the desired value of the target CV into CV99.
In this example: CV99 = 120

12 13
BASIC PROGRAMMING NOTES (continued)
As soon as you have programmed CV99, the value of CV99 will be
transferred into CV317. When the programming is nished, CVs 96, 97, and
99 will be set back automatically.
This procedure is ONLY needed when programming CVs above 255 on some
older Digitrax DCC systems.
NOTE: Please make sure that index CV32 is set to 1 and Index CV31 is set to
16 before you change any of the individual sound volume CVs. Please refer to
the decoder manual as necessary for additional CV information. CVs 31 & 32
are not required to adjust the Master Volume, CV63.
Below are some of the basic information points about the V5 decoder and its
capabilities:
From the factory the model is set to default DCC address 03
• The decoder can be set to a 2 or 4 digit address with normal addressing
on all DCC systems.
• Supports CV1 Short Address 1-127
• Supports CV17/18 Long Address 128-9999. Please add 32 to the default
value in CV29 Conguration for the decoder to recognize a four-digit
address and other cong settings.
• Supports NMRA Consisting using CVs 19 (consist address), CV21
(consist function control F1 to F8), CV22 (FL and F9 to F12 (FL is F/R
directional headlight).
• The decoder may be reset on the program track by setting CV8 = 8.
NOTE: See important information on decoder resets in the CV8 Resetting
the Decoder section.
• Manufacturer’s ID: CV8 = 151
• ESU has added additional function button capabilities (see Function
Chart) that may be controlled in a consist using CV109 (F15 to F22) and
110 (F23 to F30). CV109 programs the same as CV21, CV110 (the same
as CV22 in regards to bit values).
CV2 Start Voltage (Vmin or Vstart)
Sets the minimum speed or voltage applied to the motor on throttle speed
step 1. This can be customized to preference but is generally set where the
locomotive will either almost move consistently at SS1 or will crawl on SS1. A
setting between 1 to 3 is common.
CV3 Acceleration Rate
Sets the amount of time it will take for the decoder to apply the max voltage
set by CV5 to the motor speeding up. The setting in CV3 is multiplied by
0.896 seconds to calculate the time. The CV range is 0 to 255.
CV4 Deceleration Rate
Sets the amount of time it will take for the decoder to reduce the max voltage
set by CV5 to zero when stopping. The setting in CV4 is multiplied by 0.896
seconds to calculate the time. The CV range is 0 to 255.
CV5 Maximum Voltage (Vmax, Vfull)
Sets the maximum speed that the locomotive will move. If one model runs
faster than another at full throttle, reducing CV5 on the faster locomotive so
that they are closer in speed will allow you to run differing locos together. The
CV range is 0-255 with 255 applying the maximum voltage the decoder can
supply to the motor. CV5 must always be greater than CV6 to prevent erratic
operation.
CV6 Midrange Voltage (Vmid, Vhalf)
Sets the midpoint of the speed range. A lower setting in CV6 will have smaller
increases in speed (voltage to motor) from Vstart to Vmid with throttle speed
step advances. Once you reach the Vmid set voltage, larger increases will
occur from Vmid to Vmax as you advance the throttle.

CV8 RESETTING THE DECODER
Should it become necessary to reset the decoder to factory specs, place the
unit on the programming track of your DCC system and:
1. Enter Paged Mode programming,
2. Enter/read CV8,
3. Set/Program the value 8 into CV8.
That’s it! You have just reset the decoder to factory CV settings. This does not
affect the sounds on your decoder other than any volume settings that you
may have changed. They will be returned to factory settings.
NOTES:
• After a reset, CV8 will again read 151.
• CV1 Short Address will be active again and set to 03
• CV17/18 and CV29 will return to factory defaults
DO NOT reset the decoder using POM (Programming on the Main) as the
decoder requires a power cycle OFF to ON to complete the reset cycle.
Failure to do so may result in the decoder not properly resetting.
CV17 Long Address (Ad4) - High Byte
The value entered in CV17 determines the higher value (rst two digits) of
a long address entered into the decoder. See chart on pg. 114 of ESU V5
decoder manual #51989.
CV18 Low Address (Ad4) - Low Byte
The value entered in CV18 determines the lower value (second two digits)
of a long address entered into the decoder. See chart on pg. 49 of ESU V5
decoder manual #51989.
Manually Programming a Long (Ad4) Address:
The following information is the same as that found in the decoder manual
for determining and programming a long address manually. Some DCC
systems have automated methods for entering a long address that you may
prefer to use.
To programm a long address, you need to calculate the values for CV17 and
CV18 and enter them into the decoder. Please note that it is not possible
to program addresses via the programming mode “POM” Programming on
Main.
To program the long address proceed as follows:
• First you determine the desired address, for instance 4007.
• Then you look for the appropriate address range in Fig. 2.
The value to be entered into CV17 can be found in the column on the right.
In our example, it is 207.
The value for CV18 is established as follows:
desired address 4007
minus rst address in the address range - 3840
===============================
equals value for CV18 167
• Program CV17 = 207
• Program CV18 = 167
Your decoder is now programmed to address 4007.*
* You must still program Bit 5 of CV29 to recognize the long address. Review
the CV29 Conguration Register section for more information.

BASIC PROGRAMMING NOTES (continued)
CV29 Conguration Register
The Conguration Register, CV29, tells the decoder how to behave in a
number of ways from speed steps, to speed curves, and whether to recognize
a short or long address. See Fig. 3 to learn how the default value was reached
on the ET-44.
CV163 / 164 Alternate Horn And Bell Sounds

Auto Bell:
Many Second and Third Generation locomotives have been tted with an
Automatic Bell that is triggered when the horn is blown. In MANY cases
this cannot even be bypassed on modern locos. Before the FRA mandated
this feature on new locomotives the bell was of course turned on and off
separately. Some locomotives were delivered with a manual bell and have
been converted to an automatic bell. This creates a challenge in sound le
creation.
We realize that not every loco with a particular prime mover had this feature.
As such we have built in an option to turn the feature on and off. We will set
the default in the le to be what is most appropriate for the particular le.
To turn the Auto Bell OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8, CV311 = 4
2. Change the sound conguration of the Auto bell sound slot
CV31 = 16, CV32 = 1,CV287 = 0
To turn the feature ON - Auto Bell ON:
1. ADD the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8, CV311 = 12
2. Change the sound conguration of the Auto bell sound slot
CV31 = 16, CV32 = 1, CV287 = 1
Auto Bell Timer:
The Bell timer is amount of time the bell will play after the horn if the auto
timer is active. The timer is broken down into 1/4 of a second increments.
CV169=4 - 1 Second CV169=16 - 4 Seconds
CV169=8 - 2 Seconds CV169=20 - 5 Seconds - Default
CV169=12 - 3 Seconds
