Installation of a Sound modul

Connecting the SUSI-interface 

Connect the SUSI interface via the soldering pads of the decoder 

plate. Solder the red, blue, gray and black wires according to the 

decoder isntructions. The sound module receives its power and data 

from the decoder.

Characteristics

•  Intelligent sound control with up to 40 seconds of original sound coordinated to the operating situation 

  (i.e., speed, etc.) of the locomotive 

•   Generates the operating (motor) sound of the locomotive, "squealing" brakes, incidental noises while 

stationary (mechanical devices (e.g., air pumps, etc.), coal shovels, etc.) 

•  5 additionally adjustable noises such as whistle, bell, horn, uncoupling sound or door warning signal 

•   Sound changes as engine load changes, such as up/down grade operation; reaction to load change 

can be adjusted 

•   The "Smart-Start": When starting the locomotive, the sound module stops the decoder from operating 

until the actual starting of the vehicle synchronises with the sound of the motor. The locomotive does 

not move until the very starting sound begins.

•  Adjustable volume and audio muting: the sound can be faded or turned off by function key, 

  e. g. during travels into and away from a shadow station 

•  Provisions for a wheel sensor (e. g., reed contact, etc.) for synchronized exhaust sounds with steam 

locomotives 

•  Efficient digital output circuitry renders sounds over 3 independent channels 

•  Up to three modules can be connected to a locomotive decoder, e. g. for multi-engine locomotives 

•  Comes with speaker and resonating chamber 

•  Locomotive sounds can be downloaded; various sounds are available at www.uhlenbrock.de 

For modern diesel railcar sounds with the SUSI-interface 

Description

The Intellisound sound module is an auxiliary module for locomotive decoders with the standardized 

SUSI interface, and can be identified by the appropriate logo. The sound modules supply original, faith-

fully reproduced sounds of real locomotives. Using "intelligent sound control" the sounds produced are 

adapted to match the locomotives actual operating environment. Even when driving uphill and downhill, 

the sounds change to accurately reflect prototypical operation. When the locomotive is supposed to 

start, the sound module will stop the motor from working (via the decoder) until the actual starting of the 

vehicle synchronises with the sound of the motor. A diesel locomotive, for instance, roars right before 

it starts. The decoder stops the train from moving until the roaring is over and the motor sound begins. 

If the locomotive is stopped, the appropriate "squealing" brake sound is produced. While stationary, 

different operating noises for the-respective type of locomotive are produced by chance (coal shovels, 

compressed air). With diesel locomotives, the engine startup and shutdown sounds can be heard when 

this function is switched on and off. In addition to the driving (motor) sound of the locomotive, which can 

be switched on and off using the appropriate function key, 3 more sounds can be triggered by function 

keys. Here, depending upon the type of locomotive (as displayed in the table below), whistle, horn, bell, 

door warning / closing signal or uncoupling sounds can be played. 

If the locomotive travels out of the visible range of a model railway facility, e.g. into a shadow station, then 

"audio muting" can be softly faded out by a special function key. By pressing the function key again, the 

sound is gradually faded in, adapting itself to the existing driving conditions (i. e., sound synchronized 

to the motor speed).

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.

Declaration of guarantee 

Each component is examined before distribution for proper operation. However, if a problem should 

arise within the guarantee period of 2 years, then we will repair it for you free of charge upon receipt of 

your sales invoice. 

The warranty claim is void, if damage was caused by inappropriate treatment, use or modification. For 

EU only: Please note that, according to EMV law, this component may be operated only within vehicles 

which carry the CE designation. 

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.
