Overview

All Aboard!

Congratulations on the purchase of your SoundTraxx® Tsunami®
SoundCar™ Digital Sound Decoder™ (DSD). This User’s Guide will walk
you through the various aspects of programming your SoundCar DSD, as
well as provide some tips for troubleshooting. For advanced programming
techniques, refer to the Tsunami SoundCar Technical Reference, which
provides a comprehensive list of CVs available for use with the SoundCar,
including a description of the exact function and make‑up of each CV.

Technical Bulletins and Application Notes covering various topics are also
published periodically, and can be downloaded for free from our website at

www.soundtraxx.com.

Note: Pay careful attention to the installation instructions and follow the
recommendation on the placement of the decoder in your model so that the
Intelligent Consisting sensor is easily accessible.

Operation

Using Your SoundCar Digital Sound Decoder

Now your train doesn’t have to be limited to locomotive sounds! The 16‑bit
SoundCar DSD is the only DCC decoder to replicate railcar sounds like the
clickety‑clack, generator, brake cylinders, and more. The SoundCar DSD
uses sounds recorded from actual trains. Whether you want to include cab
cars, freight cars, reefers, passenger cars, or a caboose (or all!) in your train,
the SoundCar can reproduce the prototypical sounds appropriate to each car.

Your SoundCar DSD has been shipped with all CVs pre‑programmed so you
can begin using it immediately without having to make adjustments.

The SoundCar lets you use the function keys to re‑create the sounds
of typical actions that a train crew performs during operation, while
incorporating automated sequences for other prototypical train sounds like
the clickety‑clack, at spots, ange squeals, and wheel noise. Additionally,
certain related sounds, such as brake set up, application and release, are
grouped together and controlled by a single function key.

Default function assignments are as follows:

Function Key Effect

F0 Headlight On/Off

F1 Bell

F2 Airhorn/Whistle
F3 Short Airhorn/Whistle
F4 Spook the Livestock*

F5 FX5 Function Output
F6 FX6 Function Output
F7 Dimmer

F8 Audio Mute (4x Intelligent Consisting Enable)

F9 Generator

F10 Uncoupling and Glad Hand Release
F11 Apply/Release Brakes

F12 Coupler Clank

Note: Previous software versions do not support the "Spook the Livestock"
sound effect.

Although it’s not technically a function key, the emergency stop button also
activates the sound effect of the air being dumped from the brake line.

While these are the default settings, you may make changes to the function
mapping later. For now, set your controller to address 3, place the
SoundCar‑equipped model on the mainline, and start toggling through the
available functions to activate the effects.

Turn On the Lights

Press F0 on your cab to turn on the headlight of a cab car. Reverse the
direction and the headlight turns off as the backup light turns on. While
waiting on a siding, press F7 to dim the headlight for an oncoming train.
If you wired the FX5 and FX6 function outputs for Hyperlight lighting effects,

Tsunami SoundCar User’s Guide Page 2

Operation

pressing F5 or F6 will activate your selected effects. You can use those outputs
to incorporate lighting into the interiors of your cab cars and passenger cars.

Ring the Bell

Engineers are required to ring the bell during yard movement. To ring the bell,
press F1 on your cab. This is an on/off function, i.e., once activated, the bell

will continue to ring until you press F1 again to turn it off.

Blow the Horn/Whistle

Engineers are required to blow various signals to warn of approaching trains,
as well as to notify passengers and train crew to the planned movement of
the locomotive. There are signals for crossings, stopping, moving forward,
backing up, and more.

Using airhorn/whistle signals can add a lot of fun to your operating sessions.
Some of the more common signals are indicated in Table A. To activate the
airhorn or whistle, press F2 on your cab; the longer you press the key, the
longer the sound will play. While this feature allows you to make long or short
signals, F3 is designated as a “short” horn so those signals will have that
nice, crisp “toot” regardless of how responsive your cab controls may be.

Spook the Livestock

The Tsunami SoundCar now includes realistic livestock sounds, allowing you
to add life to your entire train! The BeastBanter feature lets you to choose
between shipping cattle or sheep in your stock cars. Please refer to the
“Sound Programming” section for more information about this feature.

During shipment of livestock by rail car, animals often become startled by
the movement of the train. Loud and sudden noises such as steam whistles,
airhorns or cylinder cocks can also excite the animals. If you have enabled
the BeastBanter feature (see “Sound Programming" section to learn how to
do so), turning on F4 will trigger the sounds of angry and frightened cattle or
sheep. Turning off F4 will reduce their anxiety level and quite them down to a

contented level.

Tsunami SoundCar User’s Guide Page 3

Operation

Start the Generator

By default, F9 controls the generator effect. While still in the rail yard, a
crew member turns the generator on before the train leaves the station.
The generator will run automatically until shut off at its nal destination. You
can re‑create this scenario by setting the generator sound effect to play
automatically. In the “Sound Programming” section of this guide, we will
discuss how to congure the generator sound effect for prototypical operation

in refrigerator and passenger cars.

Activating Other Functions and Effects

Depending on the number of function keys on your cab, you may have

additional functions available to activate.

Mute the Sound

As with all SoundTraxx DSDs, pressing F8 will mute all sound effects – great
for when you need to take a quick break from the sounds of your layout.
Pressing F8 a second time will turn the sounds back on.

Brake Squeal/Release

The sound of squealing brakes are typically heard when the train line has
a brake set applied. Pressing F11 while the train is moving will initiate the
brake set, which includes the sounds of the brake cylinder being set up and
the brake shoes squealing as they make contact with the wheels. Press F11
again and the car will respond by producing the sounds of the retainer valve
and bleed‑off as the brakes are released. The brakes can also be set and
released when the train is idle using F11 – perfect for performing a standing
brake test prior to departure. Turn F11 on to hear the brakes set up and then
turn F11 off to release and hear the retainer bleed off.

Since F11 also controls the brakes in SoundTraxx DSDs, you can sync
up the braking effects of SoundTraxx DSD equipped engines with
SoundCar‑equipped rolling stock. See “Miscellaneous Features” for more
information on F11 braking and CVs 3, 4 and 61.

Coupler Clank

Press F12 to activate the sound effect of the coupler engaging. Press F10 to
listen to the knuckle opening and the glad hands separating as the coupler
is released. See how well you can time these sound effects to the actual
coupling and uncoupling of your cars to the train!

Emergency Stop

Pressing the emergency stop button will play the sound of the air being
dumped from the emergency stop valve (also known as the “big hole”
application) to lock up the brakes.

Automated Sound Effects

Give your ngers a rest and let the SoundCar take over with automated
sound effects. Your decoder is defaulted to automatically play the
clickety‑clack and ange squeals in response to the throttle speed. Give them
a listen by increasing the throttle on your cab. Other sound effects, such
as the generator, bell and airhorn, can be programmed to turn on and off
automatically. Refer to the “Sound Programming” section for details.

Tsunami SoundCar User’s Guide Page 4

Basics of Programming

Programming Procedure

Conguration Variable (CV) is the industry adopted and NMRA Standard term
for a decoder’s user adjustable parameters. CVs allow you to adjust various
decoder properties and customize your operating experience. The address,
audio settings, motor control, lighting effects, and function assignments are
just some of the properties you can adjust with CVs. You can modify CVs
at any time and the decoder will save your settings even when the power is
turned off. If reading about CV programming already has your head spinning,
this tutorial will help you understand how CVs work.

Customize your decoder’s settings is easy, and you can adjust settings one
CV at a time by referring to this user’s guide and the SoundCar Technical
Reference. When in doubt, you can always reset the decoder to factory
defaults. Refer to “Resetting CVs” for more information.

Bits and Bytes

All the bits, bytes, and other symbols used in decoder manuals, and
differences between command stations can make CV programming difcult to
understand. Put simply, each CV contains a value that can be changed, and
changing the value of a CV will modify a specic decoder setting. However,
knowing a little more about how CV values are represented will help you
make the right adjustments. CV values can be represented in the three

numeric formats listed below:

Decimal

Decimal representation is the format you will probably use most often.
Decimal values are represented using numerals 0‑9. Each CV contains a

decimal value from 0 to 255.

Binary

Like computers, binary is the numbering system used in Digital Sound
Decoders. Binary values are called “bits” and can be represented as either 0
or 1. Each CV contains eight bits, or one “byte.” Each CV contains a binary
value from 00000000 to 11111111, which easily converts to decimal form.

Hexadecimal

Referred to as “hex,” hexadecimal values are represented using characters A
F and numerals 0 9. Each CV contains a hex value from 00 to FF. Hex allows

you to represent decimal numbers using fewer digits if your command station

has a limiting interface.

Programming by the Bits

Each CV is made up of eight bits and can be set to decimal values from 0 to

255 or binary values from 00000000 to 11111111. Most CVs contain a single

piece of data easily represented in decimal, binary, or hex.

Some CVs use individual bits to control specic features, allowing up to eight
features to be controlled using a single CV. You can set each bit to a binary

Tsunami SoundCar User’s Guide Page 5

Basics of Programming

input of 0 or 1 to modify a specic setting. For this reason, “programming
by the bits” allows you to make basic adjustments that are on/off, disabled/
enabled, etc. Because most DCC systems don’t use binary representation,
programming by the bits requires you to convert binary values into decimal
(or hex) values.

This user’s guide represents CV values in decimal form to expedite
programming. However, binary is occasionally used to represent CV values
in the SoundCar Technical Reference for CVs that are programmed by the
bits. For instance, CV 29 (Conguration Data 1) is programmed by the bits
and controls important decoder settings, such as the locomotive direction, the
decoder’s speed step mode, alternate power source, and speed table setting.

The drawing below represents a CV and shows a binary value for each bit.
Bits 1 and 4 are set to 1, and bits 0, 2, 3, 5, and 6 are set to 0, which is a

binary value of 00010010.

bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0

Refer to Appendix A to locate the decimal (or hex) values for the binary value

00010010. The appendix shows a decimal value of 18 (0x12 in hex). Now
you simply enter a value of 18 into the CV.

Binary-Decimal Conversions

You can easily convert binary values into decimal form without the conversion
chart if you know the value of the bit when it is set to 1. The decimal value of
each bit when set to 1 doubles sequentially beginning with a value of 1, from
bit 0 to bit 7. So when bit 0 is set to 1, it has a decimal value of 1, bit 1 has
a value of 2, bit 3 a value of 4 and so on. Add these values together for the
value to be entered into the CV as shown below.

bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0

When bit is
set to 1, value = 128 64 32 16 8 4 2 1

Therefore: 0 + 0 + 0 + 16 + 0 + 0 + 2 + 0 = 18

Introduction to Programming

This section details CV programming modes, reading CVs, accessing
indexed CVs, resetting CVs to factory defaults, and locking and unlocking
CVs. Due to the varying CV programming methods used by DCC systems,
we cannot provide comprehensive
instructions that address every command

station and must assume you understand

the capabilities of your system on some

level. Consult your DCC system manual or

contact the manufacturer if you need more

detailed programming instructions.

Basics of Programming

The sections of this user’s guide are categorized according to each part of
decoder operation, from basic to advanced programming, and allows you to
congure one group of CVs at a time. When you’re comfortable programming
one set of CVs, move on to the next category and explore each setting
SoundCar has to offer. Refer to the SoundCar Technical Reference for a list
of CVs detailing each adjustable setting.

Programming Modes

SoundCar supports Operations Mode and Service Mode programming.

Operations Mode

Referred to as “Ops Mode” or “programming on the main, Operations Mode
allows you to program CVs during operation even when other locomotives

and rolling stock are present. Being able to program during operation is

especially helpful when making adjustments to sound effects since you can
hear the results of the changes you’ve made. However, because data cannot
be read back from the decoder, programming on the main will not allow you

to verify CV values.

Service Mode

Service Mode programming usually requires connecting the model to a

dedicated programmer or placing it on a separate programming track.
SoundCar supports four types of Service Mode instructions:

Address Mode: CV 1 may be modied
Register Mode: CVs 1, 2, 3, 4, 7, 8, and 29 may be modied
Paged Mode: A page register is used to modify any CV indirectly
Direct Mode: All CVs may be directly modied

Reading CVs

Some command stations permit you to read the value of a CV and verify its
setting during Service Mode programming. If you have trouble reading or
verifying CVs, there may be a problem within the command station’s design
rather than with the decoder.

Try another programming mode if you experience difculties programming
or reading CVs. Many of the newer DCC systems automatically select the
appropriate programming mode and only require you to enter the CV number
and desired value. However, some DCC systems may restrict the number
of available CVs. If you’re having difculty determining the programming
modes supported by your DCC system, refer to the manual or contact the

manufacturer.

Note: SoundCar does not require a programming track booster, such as the
PTB‑100.

Tsunami SoundCar User’s Guide Page 7

Basics of Programming

Locking and Unlocking CVs

The CV Lock/Unlock feature allows you to program a decoder without the
danger of overwriting the programming in another. This is especially useful
in installations where multiple decoders are used. For example, if you have
installed a function decoder in addition to the sound decoder, you may wish
to lock the CVs after programming to prevent accidentally programming one
decoder or the other.

CV 15, CV Unlock Code
CV 16, CV Lock ID
CV 30, Error Information

To use the CV Lock feature implemented in CVs 15 and 16, bit 0 of CV 30
must rst be set to 1 (the default value is 0). This is to avoid inadvertently
locking the decoder when the CV Lock feature is not needed.

CVs 15 and 16 are used for locking and unlocking the decoder. CV 15 is the

Unlock Code and may be programmed to any value from 0 to 255 regardless

of whether the decoder is locked or unlocked. CV 16 is the Lock ID and
may be set to any value from 0 to 7, but only when the decoder is unlocked.
Attempts to program CV 16 with a value greater than 7 will be ignored.

The decoder is unlocked when the value in CV 15 matches the value in CV

16. Otherwise the decoder is locked and cannot be programmed in either
Operations Mode or Service Mode. Further, a locked decoder cannot be reset
to its factory defaults until it is unlocked. SoundCar decoders are shipped
from the factory with all CVs unlocked, that is, CV 15 and 16 are both set to 0.

Note that if the decoder is unlocked, changing the value in CV 16 will
instantly lock the decoder. You must then set CV 15 to the same value as
was just programmed into CV 16 to unlock the decoder again. If you use
the CV Locking feature for a multi‑decoder installation in one model, each
decoder must rst have its Lock Code set in CV 16 prior to the installation
of any other decoders. Otherwise, all the decoders will have the same Lock
Code and the feature will not work. First install one decoder and program its
Lock Code. Then install the next decoder and program its Lock Code. Since
the rst decoder is now locked, it will be unaffected by the programming of
the second decoder (unless you accidentally set the Lock Code of the two
decoders to the same value. If this happens you will need to disconnect one
decoder and start over). Continue in this manner until all decoders have been
installed and their Lock Codes have been set.

Follow the steps below to lock and unlock CVs:

1. Enter a value of 1 into CV 30 (Error Information) to enable the CV

lock/unlock feature.

2. Enter a value from 0 to 7 into CV 16 to set the lock code.

3. To unlock CVs, set CV 15 to the same value as CV 16.

4. To lock CVs, set CV 15 to a different value than CV 16 to unlock
CVs.

Note: CV 8 (Manufacturer ID) cannot be used to reset CVs to factory defaults

Tsunami SoundCar User’s Guide Page 8

Basics of Programming

when CVs are locked, i.e., when CV 30 is set to 1 and CVs 15 and 16 are not
set to the same value.

It is a good idea to set up a standardized system so you don’t forget the Lock
Code settings. You might, for example, set all motor decoders to a CV Lock
Value of 1, sound decoders to a value of 2, and function decoders to a value
of 3. Keeping CV 15 set to 0 will guarantee the decoder stays locked until you

are ready to begin programming.

If You Forget the Lock Code

As there are only eight possible combinations, you can easily determine a
forgotten Lock Code using trial and error with the following procedure:

Place the locomotive on the Programming Track and set CV 15 to 0. Then
try to read the value in CV 16. If CV 16 does not read back, the decoder is
locked. Set CV 15 to 1 and try reading CV 16 once more. Again, if CV 16
does not read back, the decoder is still locked. Program CV 15 to 2 and try
reading CV 16 again. Continuing in the manner, you should eventually nd
the value stored in CV 16 as it can only be programmed from 0 to 7. If you
have tried setting CV 15 to all eight values from 0 to 7 and the decoder still
does not respond, there may be a problem with the installation, the program
track, or the decoder itself and further investigation will be required.

To reiterate, follow the steps below to unlock CVs and determine the lock

code:

1. Place the model on the programming track and enter a value of 0
into CV 15.

2. Try reading the value of CV 16. If the value is not read back, CVs
are locked.

3. Enter a value of 1 into CV 15 and try reading the value of CV 16
again.

4. If the value is not read back, enter a value of 2 into CV 15 and
try again.

5. Enter values 3‑7 into CV 15 until the value of CV 16 is read back
and CVs are unlocked.

If you still can’t identify the lock code, there may be a problem with the
installation, programming track, or decoder. Contact SoundTraxx customer
support if this occurs.

If you do not have access to a programming track with read‑back capabilities
(or are uncertain as to whether it is working properly), you can also use
Operations Mode to discover the Lock Code by alternately programming CV
15 and setting another CV to a value where there is a known response. For
example, changing CV 128 (Master Volume Control) will provide auditory
feedback as to whether the decoder is unlocked by virtue of a change in
sound level. Thus, you would begin by setting CV 15 to 0 and then setting CV
128 to 0. If the volume does not fall to 0, the decoder is locked. Then set CV
15 to 1 and try programming CV 128 again. Repeat this process until you nd
a value for CV 15 that results in a change in sound volume as you change

CV 128.

Tsunami SoundCar User’s Guide Page 9

Basics of Programming

Troubleshooting Tip:

Even if you are not planning to use the CV Lock feature, it can still be
accidentally activated by inadvertently programming CV 15 or 16 with a
non‑default value. If you have a decoder that is otherwise working properly
(i.e., making sound and responding to throttle commands) but has suddenly
stopped accepting CV changes, then rst run through the procedure under “If
you Forget the Lock Code” to determine if the decoder has been locked.

Resetting the CVs or Starting Over

Occasionally, something goes wrong and the SoundCar DSD will not respond
as expected. Usually this is caused by one or more CVs being programmed
to an unacceptable value. CVs can easily be reset to their factory default

values as follows:

1. Place the model on a powered section of track. Using either Service

Mode or Operations Mode, program CV 8 to 8, or CV 30 to 2.

2. If the model is already on the mainline, cycle power to the DSD by

turning power to the track off and then back on again.

Note: If you have a SoundTraxx CurrentKeeper™ or other device
intended to maintain power to the decoder, remove power for at least
2 minutes to ensure that it is fully discharged.

3. If sounds start immediately after power is restored, the decoder did

not reset. Repeat Steps 1 and 2.

4. Approximately 6 seconds after power is restored, startup sounds

should begin, and the headlight and backup light (if connected) will
blink 16 times, indicating that CVs were successfully reset.

5. Your SoundCar DSD should now respond to primary address 3 just

like it did out of the package.

6. If you cannot get the decoder to reset, make sure it has not been

inadvertently locked (see “Locking and Unlocking CVs” for more

information).

Tsunami SoundCar User’s Guide Page 10

Basic Programming

Step 1: Configuring the Address

The rst CVs you may want to change are those that set the SoundCar’s

address:

CV 1, Primary Address Control
CVs 17 and 18, Extended Address

The SoundCar DSD can be set up to recognize either the primary (“short”)
address or the extended (“long”) address. The primary address may be
programmed with any value from 1 to 127, while the extended address may
be programmed with any value from 0001 to 9999. Whether you choose to
use the primary or extended address will rst depend upon whether your
DCC system allows extended addressing (not all of them do, so when in
doubt, refer to your system’s user manual). It will also depend upon your
preferences and your personal numbering scheme for setting decoder
addresses. One advantage of using the extended address is that since it
uses four digits, you can use a model’s road number as the decoder address,

making it easy to remember.

Note: Both the primary and extended addresses can be changed at any time
using Service Mode programming.

Primary Address

To use the primary address, set CV 1 to the desired address from 1 to 127.

Some DCC systems will also allow the decoder address to be modied in
Operations Mode (consult your system manual for details). Please note that
when programming in Operations Mode, the following restrictions apply:

• If the decoder’s primary address is enabled (i.e., bit 5 is set to 0 in
CV 29), only the extended address may be changed using Operations

Mode programming.

• Alternately, if the decoder’s extended address is enabled (i.e., bit 5 is
set to 1 in CV 29), only the primary address may be changed using

Operations Mode programming.

Extended Address

The extended address is made up of two CVs, 17 and 18. Programming
these CVs is only advisable for experienced users, as a specic protocol
is required in order for the DSD to accept the new data (see the Tsunami
SoundCar Technical Reference for details). Most command stations that
support extended addressing will automatically generate the correct protocol;
simply follow their instructions for setting the extended address.

Once the extended address is stored in CVs 17 and 18, bit 5 of CV 29
(Conguration Register 1) must be set to 1 in order for the decoder to
recognize the extended address format. If bit 5 of CV 29 is set to 0, the

decoder will continue to respond only to its primary address. For more

information related to CV 29, see the next section, “Conguring the Decoder.”

Tsunami SoundCar User’s Guide Page 11

Basic Programming

Step 2: Configuring the Decoder

The next CV you may want to customize is CV 29 (Conguration Register 1).
Customizing CV 29 requires setting its individual bit variables, as we briey
addressed in the “Bits and Bytes” section of this manual. CV 29 is used in
conjunction with other CVs to set a multitude of decoder characteristics, such

as direction and alternate power source enable.

Table. B.

CV 29 – Conguration Register 1

Bit 7 Bit 0

MD 0 EAM 0 ACK APS F0 DIR

Primary or Extended Address (EAM) – Bit 5 (EAM) of CV 29 determines
whether the decoder will respond to the primary address in CV 1 or the
extended address in CVs 17 and 18 (see “Conguring the Address” for more

information).

Alternate (Analog) Power Source (APS) – Bit 2 (APS) of CV 29 allows the
decoder to work with an alternate power source (such as DC) when a DCC
signal is not present as set by CV 12 (Alternate Power Source).

Note: The SoundCar is shipped from the factory with analog mode disabled.

Table C, on the following page, lists the correct decimal value to program
into CV 29 for a variety of operating modes. To use the table, locate the row
with the operating characteristics you desire and program CV 29 with the

associated value.

Note: Table C values are in decimal format. If your command station requires
hex inputs, you will need to convert using Appendix A.

Refer to the Tsunami SoundCar Technical Reference for more CV 29
details.

Step 3: Function Mapping

What is Function Mapping?

Function mapping allows the DSD to be recongured to allow sound effects
and function outputs to respond to different function keys. This is especially
useful if your throttle has fewer than 13 function keys, as it allows you to
select which effects are active and which keys will control them instead of

being restricted to default function assignments.

There are 14 total function mapping CVs. CVs 35‑46, are used to assign
control to function keys 1‑12, respectively. CVs 33 and 34 relate to the F0
function. CV 33 controls which outputs are active when F0 is on and the cab
is set in the forward direction. Conversely, CV 34 controls which outputs are
active when F0 is on and the cab is set in the reverse direction. If the same
effect/output is selected for both CV 33 and CV 34, that function will turn on
whenever the F0 function is on, regardless of direction.

Not all function keys can control all outputs or effects (see Table D). Note that
a function key can be set up to control more than one output.

Basic Programming

When an output is controlled by more than one function key, either function
key will turn on that output. However, the output will not turn off until both
function keys have also been turned off.

To determine the correct CV value for customizing function mapping:

1. Locate the column in Table D that corresponds to the output or sound

effect you wish to control.

2. Next, locate the row that corresponds to the function key you would

like to use to control the selected output or effect.

3. Note the number located in the box at the intersection of the row and

column you have selected.

4. Program the CV in the row selected in Step 2 with the value located
in Step 3.

Example: Swapping the Bell and Short Horn Functions

Some DCC systems label F3 on their cabs as the bell control, however, the
SoundCar’s default bell control is F1. Fortunately, if you happen to have a
cab with F3 labeled as bell control, you can use function mapping to reassign
the control so that the function label controls that utility in the decoder. Since
F3 controls the short horn function by default in the SoundCar, we will simply
swap it with F1 as follows:

1. First, reassign F3 to the bell. In Table D, locate the bell column.

Then locate the F3 row. Note the value, 1, found in the box at the
intersection of the bell column and F3 row. Now, program a value of 1
into CV 37, which controls F3. F3 should now control the bell sound

effect.

2. Next, reassign F1 to the short horn following the same procedure.

Locate the short horn column in Table D, and then locate the F1 row.
Note the value, 128, found in the box at the intersection of the short
horn column and F1 row. Program a value of 128 into CV 35, which
controls F1. Now, F1 should control the short horn sound effect.

Working With 8-Function Cabs

While the SoundCar can support 14 functions, some cabs are limited to
only 8 or 9 functions, which may leave you feeling like you can’t take full
advantage of the DSD’s features. In most cases, some clever function
mapping will allow you to access and use all of SoundCar’s available

features.

Instant Function Swapping

Entering a value of 4 into CV 30 (Error Information/Alternate Mode Selection)
will swap function assignments for F5‑F8 with the function assignments for
F9‑F12. Think of CV 30 as a sort of “shift” key when bit 2 is enabled:

F5 = Generator

F6 = Uncoupling and Glad Hand Release
F7 = Apply/Release Brakes

F8 = Coupler Clank

Tsunami SoundCar User’s Guide Page 15

Basic Programming

F9 = FX5 Function Output
F10 = FX6 Function Output
F11 = Dimmer

F12 = Audio Mute

If you do not need the mute, dimmer or extra lighting functions, you can set
CV 30 to 4 and forget about it. Otherwise, programming CV 30 back and forth
with the values 0 and 4 can be quite inconvenient and a more sophisticated

solution is in order.

Example: Function Mapping With an 8‑Function Cab

In this example, we will presume that you want to use the FX5 output for
number board lights and FX6 for a cab light. The FX5 and FX6 outputs can
be doubled‑up on F0 so that these lighting effects will turn on whenever the
headlight or backup light is on, which will free up the F5 and F6 keys.

Using Table D, we can proceed to remapping the functions. Starting with F0,
congure the forward direction (F0[f]) to control the headlight, FX5 and FX6

outputs:

CV 33 = 1 + 16 + 32 = 49

For the reverse direction (F0[r]), set F0 to control the backup light, FX5 and

FX6 outputs:

CV 34 = 2 + 16 + 32 = 50

Working With Cabs That Have Fewer Than 8
Functions

By default, your SoundCar comes with Intelligent Consisting activated by
pressing F8 four times (on, off, on, off). You may move this to a different
function key of your choice by adjusting CV 228. This CV contains a value
of 1 to 12, which corresponds to the desired function key (default value is 8).
For example, if you want to activate Intelligent Consisting by pressing F7 four
times, you would change CV 228 to a value of 7.

For additional techniques and tips, see the “Function Mapping” section in the

Tsunami User’s Guide (steam or diesel).

Tsunami SoundCar User’s Guide Page 16

Basic Programming

Step 4: Configuring the Lighting Outputs

The SoundCar has four function outputs to control the lighting effects. Each
can be congured for a variety of effects, including simple on/off lights.
Additionally, you can use Grade Crossing Logic to automatically activate a
selected lighting effect when you blow the airhorn or whistle.

The following CVs allow you to customize the lighting effects:

CV 49, Headlight Effect Select
CV 50, Backup Light Effect Select
CV 51, FX5 Effect Select
CV 52, FX6 Effect Select
CV 57, FX5, FX6 Directional Control Enable
CV 58, FX5, FX6 Lighting Override Enable
CV 59, Flash Rate
CV 60, Crossing Hold Time

Hyperlight™ Effects

Hyperlight Select – Each lighting output can be programmed to one of
several Hyperlight lighting effects as briey described below and listed in

Table E.

Rule 17 dimmable headlight – This function output is normally an on/off
output. When it is on, the output level will be reduced by approximately
60% when the dimmer function is on.

Mars Light – This effect simulates the sweeping gure‑8 pattern of this

popular warning beacon.

Pyle‑National Gyralite – The Gyralite is similar to the Mars Light, but
generates a slow, wide‑sweeping elliptical headlight pattern.

Oscillating headlights – Similar in appearance to the common
twin‑sealed‑beam headlight, the oscillating headlight uses a moving
reector to sweep the beam in a tight circular motion.

Single‑ and double‑ash strobes – The strobe effect simulates the
white‑hot burst of light associated with a xenon strobe.

Western‑Cullen D312 rotary beacon – This effect provides a spectacular
rendition of the revolving reector and bulb assembly found atop many
diesels from the 60s and 70s.

Prime Stratolite – The Stratolite is a new version of the rotary beacon,
with the prototype consisting of four individual lamps arranged in a
circular pattern, which electronically ash in a clockwise direction. The
Stratolite ashes in a mechanical “stepped” fashion, as opposed to the
smooth motion of the rotary beacon.

Tsunami SoundCar User’s Guide Page 17

Basic Programming

Type I and Type II ditch lights – These operate identically. However, if
Grade Crossing Logic is enabled, the Type I ditch light will revert to a
steady “on” state when it is not ashing, whereas the Type II lights will

turn off.

Flashing rear‑end device (FRED) – Also known as an end‑of‑train
device, this red ashing marker light is mounted on the coupler of the
rear car or on the back of the caboose to warn following trains.

Exhaust icker – This effect produces a random icker with an intensity
that increases with the train’s speed. Use this effect in power generator

cars.

Firebox icker – This effect produces a random icker that resembles
a burning re and can be used by placing a lamp in the caboose to
simulate a wood‑burning stove. The effect is improved when two bulbs
are used (one yellow and the other red or orange), each connected to a

separate function output.

Dyno‑light – This effect for steam locomotives synchronizes the lamp
brightness to the output of the dynamo so that the lamp brightness
gradually increases as the dynamo builds up speed. For diesel
locomotives, the lights will fade on and fade off to simulate the heating
and cooling of the bulb laments.

Phase Select – Phase select alters the timing of an effect so that it is 180
degrees out‑of‑phase with other effects. This allows you to have two lighting
effects that blink back and forth by setting one effect to Phase A and the other
to Phase B.

Grade Crossing Logic – When Grade Crossing Logic is enabled, it causes
a selected lighting effect to become active only when the horn/whistle is
sounded (and the corresponding lighting function is also on). This can be
used to re‑create prototypical scenarios such as causing the ditch lights to
ash at a grade crossing. Grade Crossing Logic can be used with nearly
all of the Hyperlight effects without adversely affecting the on/off, dimmable
headlight, Dyno‑light, FRED, exhaust icker, or rebox icker effects. Other
effects will either turn off (e.g., strobes and beacons) or revert to a steady
“on” state (e.g., Mars Light, ditch lights, etc.) as appropriate to prototypical

practice.

Rule 17 Headlight Operation – This converts the headlight and backup
light to independent, non‑directional lights. When Rule 17 Mode is active, the
headlight is controlled as if it is FX5 and the backup light is controlled as if it

is FX6.

LED Compensation Mode – The SoundCar’s lighting effects are designed
to work with either LEDs or incandescent bulbs. However, because of the
different brightness characteristics of the two bulb types, some lighting
effects may appear less realistic when set up with an LED. You can enable
LED Compensation Mode to correct this, which will improve the contrast
of the lighting effect by automatically adjusting the function output level to
compensate for the brightness of LED bulbs.

Tsunami SoundCar User’s Guide Page 18

Basic Programming

Setting the Hyperlight Effects

For each lighting output, there is a corresponding CV that determines its
operating characteristics. To set the Hyperlight CVs, proceed as follows:

1. Locate the CV value for the desired effect and operating mode from
Table E.

2. To enable Rule 17 Mode, add 64 to the table value. Otherwise,
proceed to Step 3.

3. If you are using LED bulbs, enable LED Compensation Mode by

adding 128 to the value from Step 1 (or Step 2 if using Rule 17
Mode). If you are using incandescent bulbs, skip to Step 4.

4. Program the nal sum for the selected function output into the
corresponding CV. Use CV 49 to congure the headlight, CV 50 for
the backup light, CV 51 for FX5, and CV 52 for FX6.

Note: The SoundCar does not support the smart rebox icker lighting effect

Setting the Flash Rate and Hold Time

CV 59 (Flash Rate) is used to adjust the ash rate of Hyperlight effects and
can be programmed with any value from 0 to 15; 0 indicates the highest
frequency and 15 indicates the lowest frequency. When Grade Crossing
Logic is enabled, CV 60 (Crossing Hold Time) can be used to adjust the

Tsunami SoundCar User’s Guide Page 19

Basic Programming

length of time in seconds that an effect will remain active after the horn/
whistle function key is released. CV 60 can be programmed with a value from
0 to 15, indicating the minimum and maximum number of seconds that the

effect will remain active.

Example 1: FRED (Flashing Rear‑End Device)

In this example, we will congure the FRED lighting effect as a backup light to
simulate the lighting mounted at the end of a freight train without a caboose.
We will also assume the use of LED bulbs and enable LED Compensation

Mode.

1. In Table E, locate the two values associated with the FRED effect

under the column labeled, “Crossing Logic OFF.” We will use the
Phase A value, 11, because the FRED effect is not designed to be
an alternating light.

2. Enable LED Compensation Mode by adding 128 to 11: 128 + 11 =

139.

3. Program CV 50 (Backup Light Effect Select) with a value of 139 to

congure the FRED effect as a backup light with LED Compensation
Mode enabled. The FRED effect will turn on when the F0 function
key (default) is pressed and the train direction changes from forward

to reverse.

Example 2: Alternating Single‑Flash Strobe Lights

In this example, we will assume use of incandescent and congure the FX5
and FX6 outputs as alternating strobe lights like those that can be found on a

cab car.

1. In Table E, locate the value associated with the single‑ash strobe

effect under the column labeled, “Crossing Logic OFF.” For the rst
of the alternating lights (FX5), we will use the Phase A value, which
is 5. To get our alternating effect, a second light (FX6) must be
programmed with the Phase B value, which is 21.

2. Program CV 51 (FX5 Effect Select) with a value of 5 and CV 52 (FX6

Effect Select) with a value of 21.

Example 3: Alternating Ditch Lights with Grade Crossing Logic

In this example, we will assume use of incandescent bulbs and congure the
FX5 and FX6 outputs as Type I ditch lights that ash when the horn is blown.

1. In Table E, locate the value associated with the Type I ditch light

effect under the column labeled “Crossing Logic ON.” The value for
Phase A is 41 and the value for phase B is 57.

2. To get the light to ash alternately, set CV 51 (FX5 Effect Select) to

41 and CV 52 (FX6 Effect Select) to 57.

3. Finally, set the grade crossing hold time to 5 seconds by

programming CV 60 (Crossing Hold Time) with a value of 5. Initially,
when F5 and F6 are turned on, the FX5 and FX6 lights should both
be steady “on.” When the airhorn is sounded, however, the two
lights will ash alternately. The lights will revert to a steady “on” state
approximately 5 seconds after the airhorn is turned off.

Tsunami SoundCar User’s Guide Page 20

Basic Programming

Setting Directional Control

CV 57 (FX5, FX6 Directional Control Enable) is used to congure the
directionality of the FX5 and FX6 function outputs. FX5 directionality is
controlled by bits 0 (forward) and 1 (reverse), and FX6 is controlled by bits
4 (forward) and 5 (reverse). Setting a bit to 1 enables the corresponding
function in the specied direction. Either function may be made bi‑directional
by setting both the forward and reverse bits to 1.

CV 58 (FX5, FX6 Lighting Override Enable) is used to congure FX5 or
FX6 so that all other lighting function outputs automatically turn off when
the corresponding function is turned on. This is ideal when you need to
use the lighting function to activate an emergency light for simulating a red
signal when a stalled locomotive is occupying the mainline. In this case, the
emergency light would be turned on and all other lights would be turned off.

Tsunami SoundCar User’s Guide Page 21

Basic Programming

Step 5: Setting the Momentum

The SoundCar decoder is designed to take into account any momentum you
have programmed into your locomotives in order to synchronize the rate of
certain sound effects with the train’s speed (such as wheel noise and braking
applications). If CVs 3 (Acceleration Rate) and 4 (Deceleration Rate) (or
CVs 23 [Consist Acceleration Rate] and 24 [Consist Deceleration Rate] if in
an active consist) are set to anything other than 0 in your locomotives, the
same value should be programmed into your SoundCar decoders to sync
the momentum to the locomotives. For more information, see “Consist Inertia
Control” in the “Consist Operations” section.

Tsunami SoundCar User’s Guide Page 22

Sound Programming

Step 6: Modifying Sound Effects

Adjust the SoundCar sound effects to suit your ear and operating settings,
by selecting additional sounds, changing volume levels or muting unwanted
sounds altogether.

Sound Mixer Controls

SoundCar provides independent controls for setting the volume level for
each sound effect, similar to a modern sound studio mixing board. To set the
volume for a particular sound effect, set the corresponding CV to any value
from 0 (i.e., mute) to 255 (maximum volume).

For the best sound quality, we advise running the mixer as “hot” as possible
(audio jargon for maximizing the sound level). First, determine which sound
effect you would like to be the loudest (typically the airhorn/whistle) and set
its volume level to around 225. Then, adjust the volume levels for all other
sounds effects relative to the airhorn volume. Finally, use CV 128 (Master
Volume Control) to set the DSD’s overall volume to your desired level. Refer
to Table F for the CVs and default values for individual sound effects.

Note: The default value of CV 128 is 192, or 75% of full volume.

A degree of caution is recommended when adjusting mixer levels to avoid
a condition known as “clipping” or “limiting,” which occurs when the sum of
two or more signals exceeds the capacity of the associated output channel.
As the name implies, clipping causes the sound signal peaks to be lopped

off and manifests as distortion accompanied by some degree of clicking or
popping sounds.

To avoid a clipping situation, consider which sounds are likely to be played
at the same time and take care to ensure that their mixer levels are not
too high. For example, the airhorn and bell are usually heard together,
and you will likely want both to be as pronounced as possible. Rather than
simply cranking both sounds up to the maximum level, start by setting one
mixer close to, but not quite at the maximum level (this leaves a little extra
“headroom”). Then, gradually increase the setting of the second mixer
channel to your desired level. If you start to hear distortion, simply decrease
the setting of one mixer channel or the other until the distortion fades away.

The individual sound channels may also be used to disable sounds that are
not accurate to your particular car or operating scenario, or that you prefer
not to hear.

Airhorn/Whistle Control

The SoundCar’s factory settings utilize F2 to control the primary airhorn (or
whistle) and F3 to control a short airhorn (or whistle). The following CVs allow
you to adjust and control the airhorn/whistle:

CV 115, Airhorn/Whistle Select
CV 129, Airhorn/Whistle Volume

Airhorn/Whistle Select

Each SoundCar DSD comes with multiple airhorn and whistle choices,
selectable by programming CV 115 with the appropriate value from Table G.

Note: Previous software versions only include 3 airhorns:

0 = Wabco E2

2 = Hancock Air Whistle

Airhorn/Whistle Volume

CV 129 sets the airhorn/whistle volume and may be programmed with any
value from 0 to 255. The default is 225.

Bell Control

By default, the SoundCar uses F1 to control the bell sound effect. The
following CVs allow you to adjust and control the bell:

CV 114, Bell Ring Rate
CV 130, Bell Volume
CV 227, Bell Select

Bell Ring Rate

CV 114 may be programmed with a setting from 0 to 15, allowing you to
adjust the bell ring rate over 16 steps to simulate the sound of an air‑rung or
hand‑rung bell. A setting of 0 yields the fastest ring rate (like an air‑ringer),
while higher values produce increasingly slower ring rates. The default value
for CV 114 is 3, but you can always experiment with other values to get the
best overall sound effect for your specic model.

Bell Volume

CV 130 controls the bell volume and may be set to any value from 0 to 255.
The default is 64.

Bell Select

CV 227 allows you to select between the SoundCar’s ve available bells. To
select a particular bell, simply program CV 227 with the appropriate value

from 0 to 4 as indicated in Table H.

Sound Programming

Generator Control

The following CVs allow you to control the generator sound effect:

CV 112, Sound Conguration 1
CV 132, Generator Volume
CV 202, Generator Probability

Function-Controlled or Automatic Generator

Bit 0 of CV 112 controls whether the generator sound effect is activated by
a function key or if it is always on. A setting of 0 (default) enables the sound
effect to be controlled by pressing F9. If you prefer the sound to always be on
(such as in a passenger car), a setting of 1 will enable the effect.

Note: When activating F9, the generator sound will play according to the
settings in CV 202.

Generator Volume

CV 132 controls the generator volume and may be set to any value from 0 to

255. The default is 25.

Generator Probability

CV 202 allows you to set the frequency of the generator sound effect,
enabling you to re‑create prototypical scenarios appropriate to your railcars.
CV 202 may be programmed with any value from 0 to 255. A value of
0 will cause the generator to never turn on, suitable for non‑refrigerator
cars. Conversely, a value of 255 will cause the generator to run constantly,
suitable for passenger cars where generators run non‑stop for climate control
purposes. Or, select a value somewhere in‑between to re‑create the sound of
a generator in a refrigerator car turning on and off according to the heat of the

day.

Clickety-Clack Control

The clickety‑clack sound effect can be adjusted to match the type of car and
the type of rail. The following CVs control the clickety‑clack sound effect:

CV 112, Sound Conguration 1
CV 116, Moving Sound Scalar
CV 131, Clickety‑Clack Volume

Clickety-Clack Sound Conguration

Bits 1 and 2 in CV 112 allow you to set the number of axles per truck and
trucks per car to synchronize the clickety‑clack rate for your model.

Use bit 1 to set the number of axles per truck. For two axles per truck, keep
bit 1 at its default setting of 0. For three axles per truck, set bit 1 to 1.

Bit 2 controls the number of trucks per car. For two trucks per car, keep bit 2
at its default setting of 0. For one truck per car, set bit 2 to 1.

Examples: If you have a bobber caboose, which only has one truck with two
axles, you will set CV 112 to 4 (bit 1 = 0 + bit 2 = 4).

Tsunami SoundCar User’s Guide Page 26

Sound Programming

For a sleeper car that has two trucks with three axles, set CV 112 to 2
(bit 1 = 2 + bit 2 = 0). To keep your passengers comfortable, you may want
to also enable the generator to always be on, so add a value of 1 to enable
bit 1, which will give you a total CV 112 value of 3.

Moving Sound Scalar

To further ne‑tune the clickety‑clack rate (as well as at spots), use CV 116
to set the proportion between the speed step and the scale speed in feet per
second (ft/s). This CV can be programmed with any value from 0 to 255 to
determine the frequency of the clickety‑clack rate based on the scale speed
of the car and the distance between rail joints. A value of 1 corresponds to

0.01ft/s. Higher values correspond to faster scale speeds, and a value of 0
will disable the clickety‑clack and at spot sound effects.

Clickety-Clack Volume

CV 131 controls the clickety‑clack volume and may be set to any value from
0 to 255. The default is 64.

Flange Squeal Control

The following CVs control the ange squeal sound effect:

CV 133, Flange Squeal Volume
CV 201, Flange Squeal Probability

Flange Squeal Volume

CV 133 controls the ange squeal volume and may be set to any value from
0 to 255. The default is 16.

Flange Squeal Probability

The ange squeal is set to run automatically using CV 201, which allows you
to set the frequency of occurrence between ange squeals based on your
operating speed and scenario. It may be desirable to set this to lower values
if your layout has a great deal of straight track and higher values if your
layout has multiple curves. The ange squeal can be disabled by setting this

CV to a value of 0.

Using Quiet Mode

The SoundCar’s quiet mode can be used to turn on sound only after the
decoder is placed into service. It will also automatically turn the sound off
when the decoder is not being used. This is particularly useful when you have
a large number of sound‑equipped trains on your layout and don’t want to
have them running sound all at once.

To activate quiet mode, simply program CV 113 (Quiet Mode Time‑out
Period) to any value from 1 to 255. This value determines the amount of time,
in one‑quarter of a second, the decoder will wait before turning off the sound.
Thus, a setting of 120 corresponds to 30 seconds.

When quiet mode is active, the SoundCar will remain silent when it is rst
powered up and then will automatically turn on the sound once it receives
a function command (other than mute). It will automatically mute the audio

Tsunami SoundCar User’s Guide Page 27

Sound Programming

whenever all functions are turned off and the time set in CV 113 has elapsed.
Setting CV 113 to 0 disables quiet mode, and sounds will begin immediately
when the decoder is powered up.

NEW! BeastBanter by SoundTraxx

SoundCar is the rst digital sound decoder designed exclusively for rolling
stock to offer livestock sound effects. Using a smart algorithm, the feature
regulates the livestock’s anxiety level based on the speed of the train. When
stopped, the cows or sheep will remain calm, resulting in less frequent and
more contented‑sounding moos or baas. When the train is set in motion, their
anxiety level increases. As speed increases, the animals become even more
upset, resulting in more frequent and “angrier” sounding moos and baas. The
following CVs allow you to congure the BeastBanter sound effect:

CV 144, Livestock Volume
CV 203, Livestock Probability
CV 226, Livestock Select

Livestock Volume

CV 144 can be set to any value between 0 and 255. The default is 100.

Livestock Probability

CV 203 allows you to control the anxiety levels of the animals while the rolling
stock is in motion. A value of 0 will keep the livestock calm and will produce
no additional noise above the baseline. A value of 255 will result in an
extremely anxious herd of animals the moment the stock car is set in motion.

The default value is 50, which translates into about a 20% increase in animal
noise as the speed of the train is increased.

Livestock Select

CV 226 is used to select between the various livestock options. A value of 0
disables the BeastBanter feature. A value of 1 is used to select cattle and a
value of 2 is used to choose sheep. Values between 3 and 255 are reserved

and will disable BeastBanter.

Note: Previous software versions do not support the BeastBanter feature.

Customizing Other Sound Effects

CV 117 (Rolling Stock Type Select) allows you to enable the following
rolling stock sound effects: at spot, generator, coupler, airhorn and bell,
clickety‑clack, ange squeal, wheel noise, and brake sounds. Customizing
CV 117 requires setting its individual bit variables, as addressed in the “Bits
and Bytes” section of this manual.

Default is 254 (only the at spot effect is disabled). Sounds provided by CV
117 can be congured to simulate different types of cars. See Table I for the
value to turn on individual sound effects. Following are examples listing the
appropriate sounds and corresponding CV values for simulating cab cars,
passenger cars, freight cars, refrigerator cars, and cabooses.

Note: If your train runs on welded rail, disable the clickety‑clack sound effect by subtracting 16

Example 1: Cab Car

Cab cars serve as a control car on push‑pull trains, which run in “reverse”
along commuter lines rather than switching the locomotive. Since they
serve as the leading end of the train in a push‑pull operation, these cars are
equipped with many of the same safety appliances found on conventional
locomotives. The sounds commonly emitted from a cab car include the
coupler, airhorn and bell, clickety‑clack, ange squeal, wheel noise, and
brake sounds. The generator effect can be either enabled or disabled
depending upon the model. Use the default value of 254 in CV 117 to enable
these sound effects, including the generator effect. Otherwise, enter a value
of 252 into CV 117 to disable the generator sound effect.

Example 2: Passenger Car

The sounds made by a passenger car include the coupler, clickety‑clack,
ange squeal, wheel noise, brake sounds, and generator effect ‑ and can be
either enabled or disabled depending upon the model. Enter a value of 246
into CV 117 to enable these sound effects. Otherwise, enter a value of 244
into CV 117 to disable the generator sound effect.

Tsunami SoundCar User’s Guide Page 29

Sound Programming

Note: The generator is used on passenger cars that are not hooked into the
locomotive’s head‑end power (HEP) to supply electricity for air conditioning,
lighting, and appliances.

Example 3: Freight Car

Freight car sounds consist of the coupler, clickety‑clack, ange squeal, wheel
noise, and brake sounds. Enter a value of 244 into CV 117 to enable these
sound effects. Since these cars are heavily used, you may also want to add
the at spot effect by entering a total value of 245.

Example 4: Mechanical Refrigerator Car

The sounds you hear from a mechanical refrigerator car, or reefer, are the
same as a freight car plus the generator. Enter a value of 246 into CV 117 to
enable these sound effects.

Example 5: Caboose

The sounds from a caboose include the coupler, Caboose whistle, clickety‑
clack, ange squeal, wheel noise, and brake sounds. Enter a value of 252
into CV 117 to enable these sound effects. The bell function key (F1 by
default) should be off and the airhorn/whistle function key (F2 by default)
should be on to play the warning whistle equipped on a caboose.

Example 6: Stock Car

Stock car sounds will include the coupler, clickety‑clack, ange squeal, wheel
noise and brake sounds. Enter a value of 244 into CV 117 to enable these
sound effects. Next, choose the desired animal type using CV 227. Enter a
value of 1 to select cattle and a value of 2 for sheep.

Tsunami SoundCar User’s Guide Page 30

Consist Programming

Step 7: Consist Operations

What is a Consist?

A consist is a group of locomotives and/or rolling stock set up to respond
to throttle commands as a single unit (i.e., a train). There are two methods
for setting up a consist with the SoundCar: Intelligent Consisting™ and

advanced consisting.

Advanced consisting is a traditional method that uses CV 19 to program each
car into or out of a consist by setting them to the same consist address.

Since you will most likely have more than one SoundCar‑equipped model
(based on our experience, we recommend installing a SoundCar in every
third or fourth unit in a train for the best results), traditional consisting
methods can be cumbersome and time‑consuming. We developed Intelligent
Consisting as a simpler option for quickly adding and removing cars from a
train without having to do any CV programming. By reducing the number of
steps required to set up consists, Intelligent Consisting represents a 90%
time‑savings over the traditional method!

Before adding cars to a consist, we recommend that you rst program each
SoundCar decoder to create its specic prole, such as consist address,
momentum (match values to those in the locomotive’s decoder), selected
sound effects and parameters, and lighting effects. The decoder will retain
this prole when the car is added to a consist. You can also adjust the
momentum and enable certain functions for the cars as part of the consist,
which is discussed later in this section.

Now, let’s get consisting! When you’re ready to set up your consist, your
rst step is to choose the method you want to use – Intelligent Consisting or

advanced consisting.

Option 1: Intelligent Consisting – DCC Consisting

With the Wave of a Wand

This easy‑to‑use feature lets you add and remove cars from your train
without all of the programming and reprogramming of individual cars required
with traditional consisting. This method requires a magnet (serving as your
“brake club”) to activate Intelligent Consisting mode, and is synchronized
with prototypical sounds. (Any common household magnet will work.) With
Intelligent Consisting, you essentially get to play the role of the brakeman!

Here’s how it works:

1. To initiate Intelligent Consisting mode, wave a magnet over the

models you want to add to the train. The sound of the hand brake
being untied will play to indicate that the decoders are waiting
(deactivated after 1 minute) for a signal from the command station to
add them to the consist.

2. Select the address of the locomotive or consist to which you want to

add the SoundCar‑equipped models.

Tsunami SoundCar User’s Guide Page 31

Consist Programming

3. Press F8 (Note: This function assignment can be remapped via

CV 228) four times to send a command to the SoundCar decoders

to add them to the train. The decoders will conrm that the cars are
hooked into the locomotive’s train line by playing the sound of the air
bleed‑off from the retainer.

4. To remove a car from the consist, simply wave the magnet over it

again. Only the cars over which the “brake club” has been waved
will be removed from the consist. When the car is released from the
consist, the sounds of the hand brake being tied down and set is
played to acknowledge that it is no longer part of the train.

Note: If you do not hear the sound effects, check to ensure that the
decoder is installed in the model according to the recommendations in the
instructions. Proper placement is imperative for the sensor to be accessible.

With Intelligent Consisting, the SoundCar decoder also monitors the active
DCC signals and remembers the status of all active addresses to instantly
synchronize the function state and throttle speed with the locomotive or
consist that it just joined. When the train pulls away, the SoundCar will create
the clickety‑clacks, ange squeals, brake sequence sounds, and more just

like any car on a prototype train.

Intelligent Consisting Example: In this example, we’re going to add three
SoundCar‑equipped models to a consist led by a locomotive with extended
address 1513. After coupling the cars and the locomotive, set your cab to the
locomotive’s address, 1513, and wave a magnet over the three SoundCar
units. Listen for the sound of the hand brakes untying and press F8 on your
cab four times. The sound of air bleeding off from the retainer conrms that
your cars are now part of the consist. To remove the cars from the consist,
simply wave the magnet over them again.

Option 2: Advanced Consisting

In addition to its Intelligent Consisting capabilities, the SoundCar DSD

also supports advanced consist operations to add and remove cars from a

train using CV 19 (Consist Address). This CV allows the SoundCar DSD to
recognize a new address assigned to the consist without changing the DSD’s

primary or extended addresses.

By programming CV 19 to a value from 1 to 127, each unit in the consist will
be assigned the same consist address. To deactivate the consist and restore
normal operation, program CV 19 to 0.

Note that when the consist address is set, the DSD will continue to respond
to instructions sent to its primary or extended address, except for speed and
direction data. The DSD will not respond to programming commands sent to
its consist address in Operations Mode; if programming in Operations Mode,
commands must be sent to the primary or extended address.

Advanced Consisting Example: This example will use the same
SoundCar‑equipped models and locomotive No. 1513 as in the Intelligent

Tsunami SoundCar User’s Guide Page 32

Consist Programming

Consisting example. We’re going to set these models to consist address
2 using CV 19. In each SoundCar model, as well as locomotive No.1513,

set CV 19 to a value of 2. Your cars and locomotive will now respond to

commands sent to the consist address. To remove the cars from the consist,
reprogram CV 19 in each decoder back to 0.

Programming Cars in the Consist

Now that you have added cars to your train using Intelligent Consisting or
advanced consisting, let’s set up your cars to respond prototypically in the

consist.

Consist Function Enable

Consist Function CVs allow each unit in the consist to have different function
properties, allowing you to better mimic prototypical operation, e.g., blowing
the air whistle on a caboose when in reverse. This function uses the following

CVs:

CV 21, Consist Function Group 1
CV 22, Consist Function Group 2

CVs 21 and 22 allow you to dene how each unit in the consist responds to
function commands sent to the consist address. When consisting is enabled,
CV 21 controls functions 1‑8, and CV 22 controls F0(f), F0(r) and functions
9‑12. This feature enhances your ability to run prototypical scenarios, such
as a train that includes passenger cars and a caboose, with separately
controlled lighting and sound effects for each unit in the consist. The default
value in CV 21 is 128 (F8 mute enabled). CV 22 is defaulted to 16 so that the

F11 train brake application is enabled.

CVs 21 and 22 are only functional when the consist address is set in CV 19.
When function commands are sent to the DSD’s primary or extended
address, the functions will operate according to default settings (see “Using
Your SoundCar Digital Sound Decoder”) or custom settings in CVs 33‑46
(Function Output Map), regardless of the values in CVs 21 and 22.

Use Tables J and K to calculate the appropriate values for CVs 21 and 22,
respectively. Refer to Table J to determine which functions you want active in
your consist, and circle the corresponding number. When you have selected
all of your desired functions, add up the circled numbers and program that

total into CV 21.

Now look over Table K and do the same: Add up all the numbers associated
with your desired functions and program the sum into CV 22.

Table K. CV 22: Consist Function Control 2

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

Function

CV Value

Note that you will have to individually program CVs 21 and 22 for each DSD
in your consist; each DSD may require a different set of values for CVs 21
and 22 depending on your model’s requirements.

Consist Function Control Example: In this example, let’s say that you want
to add a SoundCar equipped reefer, stock car and caboose to your train.
You want the generator sound to be function controlled in the reefer car. For
the caboose, you want the FRED (FX5) to ash and the air whistle enabled.
Within the stock car, you’ll want to enable the spook the livestock function.
You also want to enable the train brake, coupling and uncoupling sounds in
all cars, as well as the mute function.

Refrigerator Car – Using Table J, program CV 21 with the value
corresponding to F8 (mute), which is 128. Likewise, using Table K,
program CV 22 with the values corresponding to F9 (generator), F10
(uncoupling), F11 (brakes), and F12 (coupling). Thus, set CV 22 to 60 (4

+ 8 + 16 + 32 = 60).

0 0 F12 F11 F10 F9 F0(r) F0(f)

0 0 32 16 8 4 2 1

Stock Car – Using Table J, select the values corresponding to F8
(mute) and F4 (spook the livestock) and enter the sum of 136 (8 + 128)
into CV 21. Likewise, using Table K, program CV 22 with the values
corresponding to F10 (uncoupling), F11 (brakes), and F12 (coupling).
Thus, set CV 22 to 56 (8 + 16 + 32 = 56). Don’t forget to enable the
BeastBanter feature by selecting either cattle or sheep using the livestock

select CV 226.

Note: Previous software versions do not support the BeastBanter

feature.

Caboose – Referring to Table J, select the values for F2 (airhorn/whistle),

F3 (short horn), F5 (FX5 output), and F8 (mute) and enter their sum of
150 (2 + 4 + 16 + 128 = 150) in CV 21. Then refer to Table K and select
the values for F10 (uncoupling), F11 (brakes), and F12 (coupling). Enter
their sum of 56 (8 + 16 + 32 = 56) in CV 22.

Tip: In cab car scenarios, set CV 129 to 0 in your locomotive to mute the
airhorn during reverse movements so that only the horn from the rear car
is heard when F2 is pressed.

Note: If you are programming on the mainline, you will hear a quick
cowbell sound after changing a CV value as an acknowledgement.

Tsunami SoundCar User’s Guide Page 34

Consist Programming

Consist Inertia Control

CV 23, Consist Acceleration Rate
CV 24, Consist Deceleration Rate

CVs 23 (Consist Acceleration Rate) and 24 (Consist Deceleration Rate) can
be used to increase or decrease the acceleration and braking responses of
SoundCar‑equipped models when part of a consist. CV 23 calculates a new
acceleration rate for the consist by adding the value of CV 23 to the value
of CV 3 (Baseline Acceleration Rate). Likewise, CV 24 calculates a new
braking rate for the consist by adding the value of CV 24 to the value of CV 4
(Baseline Deceleration Rate). When CV 19 (Consist Address) is set to 0, CVs

23 and 24 are inactive.

CVs 23 and 24 may be set to any value from ‑127 to +127. Positive values
produce slower throttle responses, while negative values result in quicker
throttle responses.

If the sum of the values of CV 23 and CV 3 exceeds 255, then the nal
consist acceleration rate will be set to the maximum value of 255. If the sum
of CVs 23 and 3 is negative, the nal consist acceleration rate will be set to
the minimum value of 0.

To set a positive value, simply program the CV with the desired value from 0
to 127. To set a negative value, rst remove the negative sign from the value
and add 128. Thus, to program a value of ‑5, add 5 to 128 (5 + 128 = 133),
and program the total of 133 into the appropriate CV.

Notes: A value of 128 is equivalent to a setting of 0 and will have no effect.

When operating Intelligent Consisting, it is best to leave the values in CVs
23 and 24 at 0 unless all of the locomotives pulling the cars are set up using
advanced consisting.

Tsunami SoundCar User’s Guide Page 35

Miscellaneous Features

Step 8: Configuring the SoundCar’s
Miscellaneous Features

F11 Train Brake

As you know by now, F11 turns the SoundCar’s brake sound effect set on
and off. What you may not realize is that you can use F11 to sync up the
braking effects of SoundTraxx DSD equipped locomotives with SoundCar‑
equipped rolling stock by setting CVs 3 (Baseline Acceleration Rate), 4
(Baseline Deceleration Rate), and 61 (F11 Braking Rate) to the same values
in your locomotive and SoundCar decoders. For more information, please
refer to the Tsunami SoundCar Technical Reference, as well as the
appropriate Technical Reference for your locomotive. If CV 61 is set to a
non‑zero value, pressing F11 will slow down the locomotive and cars without
needing to adjust the throttle, which creates an actual functioning brake.

Automatic Sound Features

The SoundCar provides the ability to generate several sound functions
automatically. This is especially useful when your cab has fewer than 14
function keys to control all of the available functions and effects, or when you
are operating on a DC (analog) layout where there are no function controls at

all.

The following CVs allow you to control the SoundCar’s automatic sound

functions:

CV 193, Automatic Bell ON Set Point
CV 194, Automatic Bell OFF Set Point
CV 195, Grade Crossing Airhorn/Whistle Sensitivity
CV 197, Analog Mode Automatic Sound Conguration
CV 198, DCC Mode Automatic Sound Conguration

Automatic Sound Conguration Register

CV 197 controls which automatic sound effects are enabled when the
decoder is operating in DC (analog) mode. Likewise, CV 198 controls which

automatic sound features are enabled for DCC operation.

The following automatic sound effects are available with the SoundCar:

Automatic airhorn/whistle signals – Whenever the train is stopped or
started, the SoundCar will produce the airhorn signal appropriate to the

direction of travel as follows:

One short toot = stop

Two long blasts = forward

Three short toots = reverse

Tsunami SoundCar User’s Guide Page 36

Miscellaneous Features

Automatic grade crossing signal – When enabled, the SoundCar will play
a grade crossing signal (two long horn blasts followed by one short blast and
one more long blast) triggered by a sudden upward spike to the throttle.

Automatic bell – The SoundCar can be programmed to turn the bell on and
off at preset speed points such as may occur when passing through a yard or

station platform.

Automatic sound functions can be enabled as follows: Refer to Table L and
circle the numbers corresponding to the sound effects you would like to
function automatically. Then, add up the circled numbers and program that

value into CV 197 (for analog mode) or CV 198 (for DCC mode).

Table L.

Automatic Sound Function Enable – CV 197 (Analog Mode)

or CV 198 (DCC Mode) Suggested Settings

Automatic Bell Enable 4

Automatic Whistle Signal 2

Automatic Grade Crossing Enable 1

Now, you can set CVs 193‑195 to ne‑tune the operation of each of the

automatic sound functions.

Automatic Bell Set Points

CVs 193 and 194 determine the speed steps (or equivalent throttle voltage
in analog mode) at which the automatic bell turns on and off, respectively.
These CVs can be programmed with any value from 0 to 126, corresponding
to the speed step of the same value. CV 194 must be set to a value greater
than CV 193, or the bell will not turn on.

Example: Set CV 193 to 5 and CV 194 to 10. With these settings, the bell will
initially be off when the train is stopped. As the speed increases, the bell will
turn on once the throttle setting reaches speed step 5. The bell will remain on
as long as the engine is operated between speed steps 5 and 10. Increasing
the throttle beyond speed step 10 or below speed step 5 will turn the bell off.
Once the bell has been turned off, lowering the speed to the same setting as

programmed into CV 193 can turn it back on.

Automatic Grade Crossing Airhorn/Whistle Sensitivity

The automatic grade crossing airhorn/whistle is activated whenever there is
a sudden increase in the throttle setting (or track voltage in analog mode)
as set by the value in CV 195. This CV can be set to any value from 0 to
126, but for practical purposes, you will likely want to use a value from 3 to

10. Setting CV 195 too low will result in the airhorn going off at every speed
increase and setting it too high will require an extreme throttle change to
trigger the sound effect.

A CV 195 setting of 5, for example, requires you to quickly increase the
throttle by at least ve speed steps before the airhorn will sound.

Tsunami SoundCar User’s Guide Page 37

Miscellaneous Features

Analog Mode

While the SoundCar is rst and foremost a DCC decoder, it may be used on
a DC‑powered layout with certain limitations by enabling the analog mode
feature using the following CVs:

CV 12, Power Source Conversion
CV 29, Conguration Register 1

First, set CV 12 to 1 to enable analog mode, and then set bit 3 of CV 29 to
enable an alternate power source. Be sure to also set CV 29 for any other
desired parameters, such as the address range as discussed earlier in this
manual in “Step 2: Conguring the Decoder.”

Analog Mode Operation

When analog mode is enabled, you may control the SoundCar using an
ordinary powerpack, although operation will be a little different than when
running non‑decoder equipped units.

With the powerpack’s throttle set to 0, the SoundCar will be silent, as it has
no power. The throttle must be turned up to approximately 5 volts to provide
sufcient voltage to power‑up SoundCar’s internal circuitry. Increase the
throttle to around 7.5 volts and the SoundCar will be ready to roll.

When operating in analog mode, be careful not to exceed the SoundCar’s
input voltage rating of 27 volts. When your track exceeds 21 volts, the
SoundCar will automatically shut down and begin ashing Error Code 10 on
the lighting outputs (if connected). If you experience this, back down on the
throttle immediately.

Important: The SoundCar will work best in analog mode when using
a high‑quality, electronically regulated powerpack, preferably one that

supplies smooth, ltered DC power. Older rheostat‑style powerpacks and

pulse powerpacks will result in erratic and unreliable operation and are not
recommended for use with Tsunami DSDs. If your powerpack has a pulse
power switch, leave it in the OFF position.

Analog Mode Options

Along with CVs 12 and 29, the following two CVs control analog mode

operation:

CV 13, Analog Function Enable 1
CV 14, Analog Function Enable 2

These CVs allow you to force a function input to the ON state whenever
the SoundCar switches over to analog mode. This is most useful for turning
on lighting effects when running on a DC‑powered layout. Sound functions
may be turned on in analog mode as well, but this is less useful as they will
either run continuously or sound just once when the decoder is powered up.
Instead, use automatic sound functions (CV 197) to generate sound effects in
analog mode, as discussed earlier in this section.

Tsunami SoundCar User’s Guide Page 38

Miscellaneous Features

To enable any of the functions from F1‑F8 for analog operation, refer to
Table M. Circle the numbers corresponding to any functions you want to
enable, and then add up the circled numbers and program the sum into

Note: When you enable a particular function for analog mode operation, it
has the same effect as pressing the equivalent function key on your DCC
cab. The SoundCar’s function mapping settings will ultimately determine
which output or sound effect is activated by the enabled function.

Troubleshooting

If you have any difculties with the operation of your Tsunami SoundCar
Digital Sound Decoder, rst check this section for hints on troubleshooting.
We have found that most problems are caused by an errant CV value and
are easily corrected. When all else fails, reset the CV values back to defaults
(see the “Basic Programming” section) and try again.

SoundCar does not appear to be working.

• Address has been accidentally changed.

• Consist Address (CV 19) or Intelligent Consisting was accidentally

set.

• CV 29 has been changed to select other address type.

• Mute function (F8) is on.

• Another function is remapped to the mute function.

• Sound Volume CVs have been set to zero.

• All sound effects are disabled in CV 117 (Rolling Stock Type Select).

• Broken track pickup wire.

• Decoder is wired incorrectly.

• Speaker wire is broken.

• Speaker is burned out.

Lights and sound effects are not working in a consist.

• Consist functions are disabled. Set CV 21 and 22 to activate desired

functions (see Step 7, “Consist Operations”).

• Consist function assignments have been remapped; check

CVs 33‑46.

• Unit is not in consist.

SoundCar is not responding to Intelligent Consisting.

• Speaker is too close to the Intelligent Consisting sensor and

interfering with its operation.

• Magnet is not close enough to the sensor to activate it.

• Magnet is not powerful enough to activate the sensor.

Lights do not work.

• Function mapping is improperly set.

• Light bulbs are burned out.

• If using LEDs or 1.5‑volt microbulbs, resistor value is too large.

• If using LEDs, polarity is wired incorrectly.

• Lamp wires are broken.

SoundCar ashes lighting outputs (if connected).

• See “Diagnostic Codes” section.

Sound works for a while then quits.

• Decoder is overheating; lower track voltage.

• Speaker is damaged; replace speaker.

Speaker sounds “crackly.”

• Sound volume is too high for speaker.

• Speaker is not properly bafed.

• Speaker wire is loose.

• Speaker is damaged.

Tsunami SoundCar User’s Guide Page 40

Troubleshooting

Decoder will not program.

• Try using Operations Mode programming.

• CVs are locked; see “Basic Programming” section.

• CurrentKeeper or other similar device is interfering with

Service Mode programming.

Diagnostic Codes

Fault Light

During normal operation, Tsunami monitors a number of its input signals and
if a fault is found, reports an error code by ashing the lights (if connected).
The number of times the lights ash corresponds to the number of the error
code. The error codes that can usually be solved by the user are:

Code 10 – Over-Voltage Fault

An over‑voltage fault indicates that the track voltage is greater than 22 volts.
When this error occurs, sound will be shut off and the error code will ash
periodically until the voltage is brought below 22 volts.

Note: Tsunami SoundCars’s absolute maximum voltage input is 27 volts!
Track voltages exceeding 27 volts may cause permanent damage to the
decoder.

Code 16 – CVs Reset to Default

This code is informational only and indicates that all CVs have been reset to
their factory defaults.

On rare occasions, the SoundCar DSD may also report the following error
code, which cannot be remedied by the user and must be returned to the

factory for repair:

Code 5 – EEROM Checksum Failure
