Programming with a Märklin* Central Unit
If the sound module is attached to an Uhlenbrock locomotive decoder, all CV's can be programmed with a Märklin* Central
Unit, although they cannot be read back.
1.Turn the Central Unit off, and then on.
2.Enter the decoder address and then turn its light "on" (normally by pressing the [function]-key).
3.Turn the control knob all the way to the left (direction change position) and hold it there for approx. 10 sec., until
the locomotive light turns off.
4.Release the control knob. The rear light will now flash slowly 4 times.
5.Enter the number of the CV to be programmed (as if you were entering a locomotive address).
6.Turn the control knob all the way to the left briefly. Now the rear light will flash 4 times quickly.
7.Enter the desired value for CV.
8.Turn the control knob all the way to the left briefly. Now the rear light will flash 4 times slowly.
If additional CV's are to be programmed, repeat steps 5-8. To stop programming, press "STOP" on the Central Unit or enter
"80" as the CV number and turn the control knob all the way to the left briefly. Since programming with a Märklin* Central
Unit only allows input values of 01 to 80, the value "0" must be entered as the value of "80".
Using the page-register to access CV addresses greater than 79
CV-addresses greater than 79 can only be accessed by the page-register. This is CV 66. If a value other than zero is pro-
grammed in this CV, then that value, times 64, will be added to the CV address specified by all subsequent writes. The value
written into CV 66 must be in range 0 through 64.
The Page register (CV 65) is automatically set to the value zero upon leaving the Motorola** programming mode.
Example
You would like to program CV 82 with the value of 15. First, CV 66 must be programmed with the value 1. Next, program CV
18 with a value of 15. This will have the effect of entering the value 15 in CV 82, since the value of 1 (the contents of CV 66)
will be multiplied by 64 (and 1 x 64) = 64, and then added to the value specified by the user (18), hence: 64 + 18 = 82.
Using the offset-register to set CV values greater than 79
CV-values greater than 79 can only programmed by employing the offset-register. This is CV
65. If a value other than zero is programmed in this CV, then that value, times 4, will be added
to the CV value specified by all subsequent writes and then it will be written in the specified CV. The Offset register (CV 66)
is automatically set to the value zero upon leaving the Motorola** programming mode.
Example
Consider CV 49 to be programmed for a value of 157. First CV 65 must be set to a value of 25. Now CV 49 must be set to
value of 57. The decoder will hold 157 in CV 49, because the offset of CV 65 will be multiplied by 4 (=100) and added to 57.
After programming, reset the contents of CV 65 to zero in order to avoid unwanted offsets.
Observe: When programming CV 65 and CV 66 the mutual contents are ignored.
Loading new sounds into the module
In order to load a new sound into the IntelliSound module, the module must be separated from the locomotive decoder and be
connected via the SUSI plug into the appropriate socket of the InteIliSound load adapter (# 31 010). The module has writing
protection, which protects it module against accidental overwriting. Before new sounds can be loaded, this protection must
be removed. To accomplish this, the points illustrated in the accompanying picture must be connected (jumpered) before the
module is attached to the InteIliSound load adapter. The operating steps for changing / loading sounds are provided with the
InteIliSound load adapter. You can find a large selection of different sounds on our web page: www.uhlenbrock.de.

Switching sounds on and off
Each sound module has 4 different, adjustable sounds plus a mute switching function:
Programming
The Configuration Variables (CV's) form the basis for controlling and selecting all possible features and functions of the
decoder in accordance with the DCC standard. The sound module is connected to a loco decoder and could be programmed
by those methodes which are provided by the loco decoder. In the case of an Uhlenbrock loco decoder the sound module
can be programmed with the Intellibox, DCC Command Stations and Märklin* Central Units.
Programming with the PIKO Digi-Power-Box
or other
DCC devices
Use the programming menu of your DCC Command Station (or throttle) to select and program decoder CV's by register,
direct or Page Programming mode. Some Command Stations/throttles also support the so called "main
track programming"
(also known as "operations mode programming"). Please refer to the operating manual of your device for specific
instructions.
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.
Additionally, the mute switching function can be mapped to a function key using sound #8. As the locomotive drives out of the
visible range of a model railway, e.g. into a shadow station, then the entire sound of the locomotive can be softly faded out by
switching on this special function (preset at the factory to function f8). The sound continues to be generated by the module in
this "faded out" condition in accordance with the respective driving conditions. If the sound is gradually faded in by subsequently
switching the special function off, then the sound again will adapt to the driving conditions in effect at that moment.
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
Settings which affect the sound pertaining to the immediate operating (driving) condition can be modified to accommodate
the type of locomotive being used. These settings affect the change of sound with load changes (e.g., uphill and downhill),
the speed threshold for triggering the squealing brake sound and the switching threshold for the electrical exhaust with an
electric locomotive (E-loco).
CV 925 is used to define load sensitivity. If a value of 1 is programmed here, then the sound reacts very quickly to uphill and/or
downhill driving, whereas a value of 8 produces a retarded reaction. CV 921 sets the minimum trigger level for a change
of sound for a load increase (going uphill) and CV 922 controls the minimum trigger level for a change of sound for a load
decrease (driving downhill). All values depend on the locomotive decoder used as well as the locomotive itself, and therefore
must be determined by experimentation.
CV 924 sets the speed threshold at which the brake squealing sound is produced when the speed of the locomotive is
reduced.
CV 923 specifies the speed threshold at which point an electric locomotive (E-lok) produces sound for its cooling exhaust.
If you run a diesel locomotive, you can influence the frequency of the exhaust “chuff" sounds. CV 938 is used to define the
time between two exhaust sounds at maximum speed while CV 939 can be used to define the period at minimum speed.
The larger the value in the CV, the longer the time between the individual exhaust sounds.
The values for these CV's are preset at the factory for Uhlenbrock locomotive decoders for "common" HO locomotives, and
can be easily modified to suit other locomotives.
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 address range #1 (CV's 900 - 925). Use
the appropriate CV address from the list of CV's provided in the accompanying table.
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!
