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.
Tsunami SoundCar User’s Guide Page 1
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.
Table A.
Whistle Signals
Note: = Short Blast — = Long Blast
— — — Approaching grade crossing. (Hold final blast until crossing is occupied.)
— Flagman protect rear.
Brakes applied.
— — Release brakes, proceed forward.
When stopped, back up; when moving, stop.
Request signal from trainman.
— Warning signal (used when approaching areas with obstructed views,
approaching passenger or freight trains, and passing freight trains).
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 congure 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
Conguration 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 difcult to
understand. Put simply, each CV contains a value that can be changed, and
changing the value of a CV will modify a specic 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 specic 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 specic 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 (Conguration 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
congure 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 modied
Register Mode: CVs 1, 2, 3, 4, 7, 8, and 29 may be modied
Paged Mode: A page register is used to modify any CV indirectly
Direct Mode: All CVs may be directly modied
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 difculties 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 difculty 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 modied 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 specic 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
(Conguration 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, “Conguring the Decoder.”
