Overview

All Aboard!

Congratulations on the purchase of your SoundTraxx®Tsunami® TSU-IM1000
Digital Sound Decoder™. This User’s Guide Addendum contains the unique
information required to take full advantage of all features offered with the
Tsunami for InterMountain HO diesel locomotives. For the power user, the
Tsunami Diesel Technical Reference contains a list of all CVs available for
use with Tsunami decoders, including their exact functions and make-ups,
providing a complete reference for advanced programming techniques.

Technical Bulletins and Application Notes covering various topics are also
published from time to time and may be downloaded free of charge from our
website at www.soundtraxx.com.

Operation

Operation Overview

Each SoundTraxx Tsunami TSU-IM1000 comes with all CVs
pre-programmed so you can begin using your locomotive immediately after
installation without having to make any adjustments. However, the software
for these decoders is as unique as the prototypes and includes several
special features to enhance the experience of running your InterMountain
diesel locomotive.

The TSU-IM1000 decoder is available in three versions to accommodate the
following InterMountain HO diesel releases: F-Units – EMD 567
(P.N. 828070); SD40s – EMD 645 Turbo (P.N. 828071); and ES44ACs/
ES44DCs – GE GEVO-12 (P.N. 828074). This addendum describes features
for each version. Additional programming information can be found in the
Tsunami Diesel Technical Reference, available for download free of charge at
www.soundtraxx.com.

Operation

Function Mapping Tables

CVs 33 – 46 allow you to customize which DSD outputs or sound effects are
controlled by which function keys. Each function input, F0 through F12, is
assigned a unique CV that allows the corresponding function control to be
redirected to up to 14 different DSD function outputs or sound 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 F0 CVs.

Note: All function inputs cannot be mapped to all outputs. Tables A and B
graphically indicate which inputs can control which outputs based on the
locomotive being used. In each table, bold numbers indicate default values.

Also note that Tables A and B are specic to TSU-IM1000 decoders and

contain slightly different values than those in the Function Mapping Table
provided in the Tsunami Diesel Technical Reference.

Operation

Locomotive Lighting Effects

Each TSU-IM1000 decoder includes six lighting outputs that have been
pre-programmed to match the locomotive’s lighting features. Each output can
be independently set to any of 15 different Hyperlight™ lighting effects, which

include dimmable headlight, Mars light, Gyralight, single and double-ash

strobe lights, and Type I and II ditch lights, among others. Table C highlights
the default lighting outputs of each decoder as they correspond to the six pins
on the connector, including which CV adjusts that output’s Hyperlight effect.
For example, to change the ditch lights on a GE GEVO-12 decoder from
Type I to Type II, adjust the values in CVs 52 and 53. Additional information
related to lighting effect CVs 53 – 58 immediately follows Table C.

CV 53: FX5B Lighting Control

CV 53 is used to control the second lighting output associated with
Function 5 (i.e., FX5B). FX5B can be programmed with any of SoundTraxx’s
Hyperlight lighting effects. Program FX7 as indicated in Tables A and B of
this addendum to turn on FX5B lighting control. Refer to the Tsunami Diesel
Technical Reference for full information related to programming CV 53 for
FX5B lighting control.

CV 54: FX6B Lighting Control

CV 54 is used to control the second lighting output associated with
Function 6 (i.e., FX6B). FX6B can be programmed with any of SoundTraxx’s
Hyperlight lighting effects. Refer to the Tsunami Diesel Technical Reference
for full information related to programming CV 54 for FX6B lighting control.

IMPORTANT NOTE: Lighting function FX6B is not directly supported on the
6-pin wire harness. To use FX6B lighting control, you must solder a wire to
the FX6B output. To locate the FX6B output, orient the decoder so that the
6-pin connector is on the left side and the three 2-pin connectors are on the
right. Flip the decoder over (top over bottom, not end over end) so that the
6-pin connector is on the left underside. The FX6B output will be the top
right-hand pad in the set of six pads on the far left side of the decoder.

CV 57: FX5, FX6 Directional Control

CV 57 is used to control the directionality of function outputs FX5A, FX5B,
FX6A and FX6B. Setting a bit to 1 enables the corresponding function in the
indicated direction. To make a function bidirectional, set both the forward and
reverse bits to 1. Refer to the Tsunami Diesel Technical Reference for full
information related to programming CV 57.

CV 58: FX5, FX6 Lighting Override

CV 58 can be used to congure FX5 and FX6 so that all other lighting

function outputs automatically turn off when the corresponding function is
turned on. For example, if Bit 0 of CV 58 (i.e., FX5OVR) is left at the default
setting of 0, FX5 will operate normally. However, if FX5OVR is set to 1, the
headlight, backup light and FX6 will turn off automatically when FX5 is on.
Note: If FX5OVR and FX6OVR have both been set to 1, FX5 will have
precedence.
