Fahrzeug-/Funktionsdecoder ab Firmware-Version 1.11 3 Sound module from firmware version 1.14
1 Introduction
The sound modules SH05A and SH10A are operated at the SUSI interface of a compatible car decoder. It can be used for
all data formats supported by the vehicle decoder.
Our SUSI sound modules can be electrically connected to all decoders with SUSI interface. Whether 3.3 Volt or 5 Volt
signals are used for the data and clock line is irrelevant. However, please note the maximum supply voltage of 30 Volt!
An operation on AC systems with change-over pulse is not permitted!
The change-over pulse leads to the destruction of the SUSI sound module!
Our SUSI sound modules must therefore not be installed in models which are also operated with analog AC voltage.
Our SUSI sound modules are not simplified products. In principle all sound functions are supported, which a sound decoder
would also support. There are only some minor restrictions. Other SUSI sound modules available on the market usually
have a clearly limited sound generation, which is not comparable with sound decoders at all. To make this possible, our
SUSI sound modules require a permanent supply of all data required for operation via the SUSI interface.
Unfortunately not all decoders on the market output such a signal at their SUSI interface. We can therefore not guarantee
an error-free function, if you connect the SUSI sound module to a decoder of the competitors. If you are unsure, please
contact us.

6 Installing the sound module
6.1 Preparation
Before installation, the locomotive must be checked for perfect electrical and mechanical condition. Defects or soiling must
be removed before installation. Basically the instructions of the locomotive manufacturer must be observed.
Before installing the sound module, the locomotive must also be checked for proper function in digital mode. With new
locomotives it is recommended to run the locomotive in each direction of travel for half an hour.
Furthermore all existing capacitors, especially at the connections for the light and the motor, have to be removed.
We recommend using double-sided adhesive tape to fix the sound module.
With sound modules, always solder the speaker first.
Carry out all soldering work in a de-energized state.
Avoid test drives with stripped unsoldered cable ends.
6.2 Check after installation
The first test should first be carried out in programming mode (e.g. by reading the manufacturer‘s code). If there is no
proper feedback to the central unit (“Error“), please check the assignment of the connections again.

6.3 Installation
There are three variants for connecting the sound module:
1 If your locomotive decoder has a SUSI standard socket, you should use the sound module SH05A-2 or SH10A-2. It
has the necessary connection cable for this socket. You can easily plug the connection cable of the sound module into
the interface.
2 If your locomotive decoder has SUSI soldering connections, the sound module must be wired individually. You should
use the sound module with the connecting leads for this purpose (SH05A-3 or SH10A-3).
3 The sound module SH05A-0 or SH10A-0 should only be used by experienced model railroaders, because here the
connecting wires have to be soldered directly onto the sound module.
Connect the wires of the sound module according to the following scheme:
black wire ....................... Ground (GND)
grey wire ......................... SUSI data (ZDAT)
blue wire ......................... SUSI clock (ZCLK)
red wire .......................... Supply voltage (ZVS)
brown wires .................... Speaker
The “VS” connection of the sound module must be connected to the “ZVS” connection of the decoder, if the decoder has
one. If not, use the “VS” connection of the decoder.

7.2 Setting options
The properties of the sound module for operation can be changed as often as desired by programming the “Configuration
Variables” (CV) or the parameters (par). Please take the programming informations out of the instructions of your
programming device.
The sound module always occupies the CV ranges 1 and 2, so an additional SUSI module must be set to CV range 3
(CV897/par897 = 3). The SH05A or SH10A sound module can remain connected for this purpose, as it does not react to
readout or programming commands from CV897/par897. This avoids the cumbersome and difficult to understand “CV
banking” procedure (see SUSI specification version 3.10 for more information).
Hint:
If different speed levels are programmed in the locomotive decoder in DCC mode than in the driving unit, malfunctions may
occur. These also affect connected sound modules. Please also note the instructions for your digital system.

Fahrzeug-/Funktionsdecoder ab Firmware-Version 1.11 19 Sound module from firmware version 1.14
7.4 Operation
Put the locomotive on the programming track and read out the manufacturer identification of the sound module (CV900/
par900). The default value should be 97. Program the desired locomotive address and start running the locomotive
keeping these setup values. After the first check you can vary the CV or parameters of the locomotive according to your
requirements.
In case your programming device indicates “Error“, please check again the correct wiring of the locomotive and pay
attention to the notices for connecting the programming track. Never put such a locomotive into operation!
Please take the mapping, which sound flow corresponds to which sound, from the instruction of the particular sound
project. Not all sound flows from 1 to 16 must contain sounds.
Starting delay:
The starting delay from speed level 0 to speed level 1 (CV63/par016) of the locomotive decoder should be set to a suitable
value. Unsuitable values will result in the starting of the locomotive not matching the noise level. The exact value depends
on the individual sound data.
Hint:
The acceleration time (CV03/par011) and the braking time (CV04/par012) of the locomotive decoder should be set to at
least value 8. Times that are set too low will cause some sound sequences to be skipped and cannot be played back! If
necessary the values of CV/par951 and CV/par952 can be increased step by step for fine tuning.
