CV 1
Primary Address Control
Description
CV 1 contains the decoder’s primary address from 1 to 127.
0 A6 A5 A4 A3 A2 A1 A0
A0-A6: Decoder Address
0: Not used. Must be set to 0.
Additional Information
The decoder will process all valid instruction packets containing an address
that matches the value contained in this register when bit 5 (Extended
Address Enable) of CV 29 (Conguration Register 1) is set to 0.
Programming this register with a new value will automatically reset CV 19
(Consist Address) to 0 and clear bit 5 of CV 29.
The decoder will ignore commands that attempt to program this register with
values outside the range of 1 to 127.
Note: CV 1 can only be changed in Operations Mode if the extended address
is enabled.

CV 3
Baseline Acceleration Rate
Description
CV 3 contains a value from 0 to 255 that sets the decoder’s acceleration rate.
D7 D6 D5 D4 D3 D2 D1 D0
D0-D7: Baseline Acceleration Rate
Additional Information
The acceleration rate may be calculated as:
Seconds/Speed Step = CV 3 x 0.896 ÷ Number of Speed Steps
When CV 3 is set to 0, the speed-related sounds will respond almost instantly
to increases in throttle setting, equivalent to no momentum. When set to 255,
it will take the decoder sounds approximately 3.8 minutes to accelerate to full
speed from a standing stop.
It is recommended that CV 3 be set to a non-zero value when operating the
decoder in 14 or 28 speed-step mode, as the throttle will interpolate between
speed steps during acceleration to produce a smoother overall response.
Note: For this CV, the value in a SoundCar decoder should match the value
in a Tsunami-equipped locomotive when in a consist.

Description
CV 4 contains a value from 0 to 255 that sets the decoder’s deceleration rate.
D7 D6 D5 D4 D3 D2 D1 D0
D0-D7: Baseline Deceleration Rate
Additional Information
The deceleration rate may be calculated as:
Seconds/Speed Step = CV 3 x 0.896 ÷ Number of Speed Steps
When CV 4 is set to 0, the speed-related sounds will respond almost instantly
to decreases in throttle setting. When set to 255, it will take the decoder
sounds approximately 3.8 minutes to come to a full stop from top speed.
It is recommended that CV 4 be set to a non-zero value when operating the
decoder in 14 or 28 speed-step mode, as the throttle will interpolate between
speed steps during braking to produce a smoother overall response.
Note: For this CV, the value in a SoundCar decoder should match the value
in a Tsunami-equipped locomotive when in a consist.

CV 11
Packet Time-out Value
Description
CV 11 contains a value from 0 to 255 that corresponds to the time period
allowed to elapse between receipts of valid packets addressed to the
decoder before the speed-related sound effects stop.
Bit 7 Bit 0
D7 D6 D5 D4 D3 D2 D1 D0
D0-D7: Packet Time-out Value
Additional Information
The time-out period is calculated in seconds as:
Time-out Period = CV 11 x 0.25
A value of 0 disables the time-out period, causing the sounds to play
indenitely without receiving another packet.
For all other values, the decoder maintains an internal timer, which is reset
every time the decoder receives a valid broadcast address packet or other
valid packet with an address that matches the decoder’s primary address, or
if enabled, the extended address or consist address.
In the event no valid packets are received within the prescribed time period,
the decoder will bring all speed-related sound effects to a stop at the rate
set in CVs 4 and 24. The state of the auxiliary function outputs will remain
unchanged.

Note: This CV is most useful for turning on lighting effects when running on a
DC-powered layout. Sound functions may be turned on in analog mode, but
this is less useful as they will either run continuously or sound just once when
the decoder is powered up. Instead, use the automatic sound functions
(CV 197) to generate sound effects in analog mode.

CVs 17, 18
Extended Address
Description
CVs 17 and 18 comprise a “paired” CV, meaning that the two CV registers
hold one piece of data. In this case, the CV pair holds the 14-bit extended
decoder address.
CV 17 Extended Address MSB
A15 A14 A13 A12 A11 A10 A9 A8
CV 18 Extended Address LSB
A7 A6 A5 A4 A3 A2 A1 A0
A0-A15: Extended Address Value
Additional Information
The extended address allows the decoder to be assigned to one of 10,179
addresses ranging from 0xC000 to 0xE7FF. Note: Most command stations
will only recognize addresses 0001 to 9999. The extended address will only
be recognized by the decoder when bit 5 (Extended Address Mode Enable)
of CV 29 (Conguration Register 1) is set to 1. Once this bit is set, the
decoder will not recognize its primary address until CV 29, bit 5, is cleared.
CV 17 contains the most signicant byte and must be loaded with values
within the range of 0xC0 and 0xE7. CV 18 contains the least signicant byte
and may contain any value.
To determine the extended address value, add the desired four-digit
extended address to the number 49152. Divide the sum by 256. Program
CV 17 with the quotient value and CV 18 with the remainder value.
Example: Calculate CV 17 and 18 register values for extended address 7152.
1. 7152 + 49152 = 56304
2. 56304 ÷ 256 = 219 Quotient; 240 Remainder
3. Program 219 into CV 17
4. Program 240 into CV 18
Note: Most command stations will perform these calculations automatically
when setting the extended address. However, it’s helpful to know how to
derive the appropriate register values.
Tsunami SoundCar Technical Reference Page 12
Primary CVs
Because CVs 17 and 18 are a paired CV, programming order is important.
Always write to CV 17 rst, and then write to CV 18. The decoder will ignore
commands that attempt to program these registers out of order or with values
outside of the allowable range of 0xC000 to 0xE7FF.
These CVs may be changed in Service Mode at any time, but may only be
changed in Operations Mode if CV 29, bit 5, is cleared (i.e., CV 1, Primary
Address, is enabled).
Default Value: CV 17 = 192
CV 18 = 3 (Long Address 0003)

CV 19
Consist Address
Description
CV 19 contains address and direction data for consist operation.
CDIR A6 A5 A4 A3 A2 A1 A0
A0-A6: Consist Address Value
CDIR: Consist Direction
0 = Normal direction
1 = Reverse direction
Additional Information
A0-A6 (bits 0-6) assign the consist address from 1 to 127. If A0-A6 = 0,
consist commands will be ignored. Otherwise, when the decoder receives
a valid command packet with an address that matches the consist, that
packet will be processed just as any other packet would be, with the following
exceptions:
• Long form CV access instructions will be ignored.
• The direction within a speed/direction or advanced operation packet is
inverted if CDIR (bit 7) = 1.
• Only the auxiliary functions enabled in CVs 21 and 22 are allowed to
change.
CDIR (bit 7) denes the orientation of the model within a consist and
species whether the direction bit in a speed/direction data packet should be
inverted.
When the consist address is active, speed/direction and advanced operations
packets sent to the decoder’s primary address (or extended address, if
enabled) will be ignored. All other instruction packets sent to the decoder’s
primary (or extended) address, including CV access and function control, will
be processed as normal.
To summarize, setting CV 19 to 0 or 128 disables consist addressing. Setting
CV 19 to a value from 1 to 127 enables consist addresses 1-127 with the
model oriented forward in the consist. Setting CV 19 to a value from 129 to
255 enables consist addresses 1-127 with the model oriented backward in
the consist.

CV 23
Consist Acceleration Rate
Description
CV 23 contains a value from -127 to +127 that corresponds to the decoder’s
consist acceleration offset.
SIGN D6 D5 D4 D3 D2 D1 D0
D0-D6: Consist Acceleration Value
SIGN: Sign
0 = Positive value
1 = Negative value
Additional Information
When the consist address is active, the consist acceleration rate is added to
or subtracted from the decoder’s base acceleration rate (CV 3) depending on
the Sign bit (bit 7). The acceleration is then calculated as:
Seconds/Speed Step = (CV 3 + CV 23) x 0.896 ÷ Number of Speed Steps
If the sum of CVs 3 and 23 is a negative value, then the acceleration rate
is set to 0 (i.e., acceleration is instant). If the sum of CVs 3 and 23 exceeds
255, then the acceleration rate is set to the maximum value of 255.
CV 23 has no effect when the consist address (CV 19) is set to 0.
To summarize, a CV 23 value from 0 to 127 will increase the decoder’s base
acceleration rate. Conversely, values from 129 to 255 will decrease the
decoder’s base acceleration rate. A value of 128 is equivalent to a setting of 0
and will have no effect.
Note: When operating Intelligent Consisting, it is best to leave this value at
0 unless all of the locomotives pulling the cars are set up using advanced
consisting.

Description
CV 24 contains a value from -127 to +127, which corresponds to the

SIGN D6 D5 D4 D3 D2 D1 D0
D0-D6: Consist Deceleration Value
SIGN: Sign
0 = Positive value
1 = Negative value
Additional Information
When the consist address is active, the consist deceleration rate is added to
or subtracted from the decoder’s baseline deceleration rate (CV 4) depending
on the Sign bit (bit 7). The deceleration rate is then calculated as:
Seconds/Speed Step = (CV 4 + CV 24) x 0.896 ÷ Number of Speed Steps
If the sum of CVs 4 and 24 is negative, then the deceleration rate is set to 0
(i.e., braking is instant). If the sum of CVs 4 and 24 exceeds 255, then the
deceleration rate is set to the maximum value of 255.
CV 24 has no effect when the consist address (CV 19) is set to 0.
To summarize, a CV 24 value from 0 to 127 will increase the decoder’s
baseline deceleration rate. Conversely, values from 129 to 255 will decrease
the decoder’s baseline deceleration rate. A value of 128 is equivalent to a
setting of 0 and will have no effect.
Note: When operating Intelligent Consisting, it is best to leave this value at
0 unless all of the locomotives pulling the cars are set up using advanced
consisting.

F0 (bit 1) should be cleared to 0 if you are using 14 speed-step mode. For 28
or 128 speed-step mode, bit 1 should be set to 1.
APS (bit 2) must be set to 1 in order to activate an alternate power mode
as programmed into CV 12 (Power Source Conversion). To activate analog
mode, CV 12 must be set to 1.
ACK (bit 3) will always read as 0 because the decoder does not support
advanced acknowledgment.
Tsunami SoundCar Technical Reference Page 19
Primary CVs
EAM (bit 5) must be set to 1 in order to activate extended address capability.
Note that once bit 5 is set, the decoder will respond to commands sent to the
extended address only; commands to the primary address will be ignored.
This can be a problem if you are using a command station that does not
support extended addressing and bit 5 is accidentally programmed. In such a
scenario, connect the decoder to a programming track to access CV 29 and
clear bit 5.

CVs 33-46
Function Output Map
CVs 33-46 allow you to customize the function key assignments that control
the decoder’s outputs, sound effects, and lighting effects. Each function
input, F0 through F12, is assigned a unique CV that allows the corresponding
function control to be redirected to up to 15 different decoder function
outputs, sound effects, or lighting effects. This allows a single function key to
control more than one output if desired.
The F0 function has two CVs – one for forward direction and one for reverse.
Function outputs mapped to these registers will be directional unless the
same output is mapped to both CVs.
Note that all function inputs cannot be mapped to all outputs. The SoundCar
Function Mapping Table graphically indicates the inputs that can control each
output.

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 activated.
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
reector to sweep the headlight beam in a tight circular motion.
Tsunami SoundCar Technical Reference Page 37
Lighting Effect CVs
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 reector 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, opposed to the smooth motion of the rotary beacon.
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 throttle speed. The most realistic
effect can be achieved by placing a red or orange lamp under the
model’s exhaust port, and out of direct view. As the speed steps
ramp up, the effect will glow brighter, imitating unmufed exhaust
gases and sparks. 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, 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 off to simulate the
heating and cooling of the bulb laments.
PHSE: Phase Select
0 = Phase A
1 = Phase B
Phase Select (bit 4) – This bit alters the timing of the lighting effect
so that it is 180 degrees out-of-phase with other lighting effects.
This allows you to have two lighting effects blinking back and forth.
Set one effect to Phase A and the other to Phase B.
Tsunami SoundCar Technical Reference Page 38
Lighting Effect CVs
XING: Grade Crossing Logic Enable
0 = Grade Crossing Logic disabled
1 = Grade Crossing Logic enabled when horn function

Grade Crossing Logic (bit 5) – This bit causes the lighting effect
to activate only when the horn/whistle is sounded (and the
corresponding lighting function key is on). This can be used to 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 affecting the on/off, dimmable headlight,
Dyno-light, FRED, engine exhaust, 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.
R17: Rule 17 Mode
0 = Rule 17 Mode disabled
1 = Rule 17 Mode enabled
Rule 17 Mode (bit 6) – This bit converts the headlight and backup
light into 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: LED Compensation Mode Enable
0 = Incandescent-compatible lighting outputs enabled
1 = LED-compatible lighting outputs enabled
LED Compensation Mode (bit 7) – This bit improves the contrast of
the lighting effects to compensate for the brightness of LEDs.
