Fahrzeug-/Funktionsdecoder Sound module

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.
