Sound depended Auxiliary functions
Loads that are controlled depending on the sound can be connected to outputs SA1 and SA2. In a steam locomotive
a smoke generator can be connected to SA1 and lighting for the firebox to SA2. With an E-Locomotive or Commuter
train two lighting types can be connected. To SA1 a simulated brake disc glow or a brake light and to SA2 the flash
of a disconnecting power pickup. For Diesel locomotives only output SA1 for a simulated brake discs glow. On the
above mentioned loads the second pole is connected to
+20V. For LEDs please take note of the polarity.
Extern input for wheel revolution sensors
In order to produce the wheel synchronization to the chuffs of
a steam locomotive or curve screeching in an E-locomotive
or diesel locomotive, the sound module has a special sensor
input. As sensor, a reed switch or a Hall sensor together with
magnets on a locomotive wheel (Bogie for curve screeching),
or a light sensor with the corresponding markings on a wheel can be used. The reed switch, Hall sensor or light sensor
are connected to the solder pads as shown in the diagram.
Attaching the sound module
Using a piece of double-sided "sticky" tape, fasten the sound module to any place in the locomotive. The sticky tape
holds the sound module reliably in place and protects it from coming in contact with other wires, components, etc.
Start-up
Make sure that placing the module in the locomotive will not cause a short circuit! Also insure that, once you have
replaced the body (shell) of the locomotive no wires are "pinched" which could also cause short-circuits to develop.
A short circuit between engine, lighting, pickup shoe, wheel sets and the module can possibly destroy the
decoder’s components as well as the electronic of the locomotive!
Switching sounds on and off
The individual sounds can be switched on and off using special function keys on your digital Command Station/
Throttle. The allocation (or mapping) of the various sounds to individual special function keys can be modified using
CV's 903 - 915.
Decoders are delivered with sounds initially allocated as indicated in the above table.

If the locomotive runs out of sight on a layout, e.g. into the shadow station, the sound can be faded out by the “mute”
function with a special function key (f8 in factory default state), switching all sounds off. Internal to the module the
sound continues to be issued according to the driving condition. If the sound is faded in again by switching the special
function off, the sound will be audible again and matching the driving status.
Volume
Speaker volume can be changed via CV 902. As shipped from the factory, the volume is set to its maximum level.
Configuring the dynamic change of sound
Some settings, which concern the change of the sound in regard to the present driving conditions, can in each
case be adapted to the type of locomotive used. The settings concern the change in sound change with loading
(uphill and downhill), the speed threshold for starting the brake screeching and switch-on threshold for the electric
blower in an E-locomotive. CV 937 A changes the sensitivity to load regulation. If a value of 1 is programmed here,
the sound reacts very quickly to uphill and downhill running. A value of 8 results in a delayed reaction. With CV
938 A the trigger threshold for a sound change for uphill driving (Load increase) can be set and with CV 939 A the
trigger threshold for a change in sound for downhill driving (Load reduction) can also be set. All values depend on
the locomotive decoder and the locomotive used and must be determined by test driving. With CV 936 the speed
threshold can be changed and the brake screeching starts when the locomotive speed is reduced. CV 934 sets the
speed threshold at which E-locomotives sound the cooling blower is closed. In a steam locomotive the repeat rate
of the chuffs can be influenced. In CV 938 the time between 2 chuffs at maximum locomotive speed can be set, in
CV 939 for minimum locomotive speed. In both cases, the larger the value in the relevant CV, the longer the time
between the chuffs. With CV 937 a time can be set for how long an idle sound in idle running is to be heard. All
ex-factory settings are for Uhlenbrock locomotive decoders and preset for H0 locomotives, but can be matched to
other vehicles without problems.
Loading new sounds into the module
If the sound in the module is to be changed, then the module must be separated from the locomotive decoder and
the SUSI-plug inserted into the socket of the IntelliSound Loading adapter (Part No. 31 010, or 31 050). The operating
steps for changing the sound are found in the manual for the IntelliSound Loading adapter. A large selection of various
sounds can be found on our internet site “www.uhlenbrock.de”.
Loading custom sounds
In addition to the pre-programmed sounds it is possible to add a maximum of 4 custom sounds with the Intelli-Sound
Loading adapter. For this you use the Sound program SUSI-SoundManager and your own sounds in wav format.
Controlling several sound or special function modules from a locomotive decoder
Up to three sound or special function modules can be controlled through a single SUSI interface. CV 897 is used
to allocate each module's own CV address range, thus allowing each module to be programmed independently. To
accomplish this, each module must first be connected individually to the locomotive decoder. Its own CV address range
is determined by assigning the value 1, 2 or 3 to CV 897. Once all modules are connected, each can be addressed
and programmed within its own CV address range. The CV to be modified will depend on the CV address range as
specified in the list of CV's at the end of this document. Please you note that the explanations in the preceding sections
refer to CV address range #1 For changing the address range you have to use the congruent CV-addresses for the
2. or 3. address range from the CV table.
Programming
The basis of all the decoder’s configuration options is the Configuration Variables (CV’s) as in the DCC standard. The
Sound module can be programmed with the Sound Loading Adapter, or via a locomotive decoder. When programming
via locomotive decoder all methods supported by the locomotive decoder are available. By using an Uhlenbrock
locomotive decoder, an Intellibox, DCC Centre or Motorola centre can be used for programming. When using third
party devices please refer to the locomotive decoder programming section of that device’s manual.
Programming with the Intellibox
We recommend that regardless of the format the locomotive decoder will be using later on, when it is connected to
an Uhlenbrock decoder, it be programmed via the Programming Menu for DCC decoders. For exact detail on the
method please read the corresponding chapter in the Intellibox Handbook.
Programming with DCC devices
When using the Programming Menu of your DCC Centre to program the sound module, if it is connected to an
Uhlenbrock decoder, program it by the CV direct Programming method. For exact details on the method please read
the corresponding chapter in the Intellibox Handbook.
Programming with Märklin* Central Unit
As long as the sound module is connected to an Uhlenbrock decoder all CV's can be programmed with a Märklin
center, but not read.
1. Switch Center off and on.
2. Select the address of the decoder and switch the light on.
3. Operate the direction change-over 5 times in quick succession with the stationary locomotive (speed step 0),
until the light turns off.
4. Set the speed controller to "zero". The rear light now flashes slowly 4 times.
5. Enter the number of the CV that is to be programmed.
