36 Information LE1835
The quality of these sound effects depends solely on the S.U.S.I. module used and not on the
locomotive decoder!
9.1 Connecting a S.U.S.I. module
You may connect all sound and/or function modules to the S.U.S.I. interface of the LE1835A/E
which correspond to the specification of the S.U.S.I. interface. To connect a sound or function
module, you will only have to plug the 4-pole interface plug of your sound or function module into
the interface of the LE1835A/E. Make sure that the plug is aligned correctly, as there is only one
way of plugging it into the interface.
9.2 Setting (programming) the S.U.S.I. module
Analogue to the locomotive decoders, there are also various ways of setting S.U.S.I. modules.
These settings are also saved in configuration variables (CVs). If you want to make changes to
these CVs, proceed as if you wanted to change the CVs of the locomotive decoder. The S.U.S.I.
module is programmed "through the decoder" as it were. Based on the number of the CV, the
locomotive decoder will know whether the S.U.S.I. module is to be addressed and will transmit the
programming commands via the S.U.S.I. module. Please refer to the operating manual of your
module to learn about the settings possible for your S.U.S.I. module.
The settings of the S.U.S.I. module can be carried out both through "Programming in operational
mode (PoM)" or "Programming on the programming track". When using Digital plus by Lenz
®
systems, you can change the CVs 1 to 999 with PoM, while "Programming on the programming
track" is currently used for the CVs 1 to 256. The CVs 897 to 1024 have been defined for the
S.U.S.I. module. A special programming method has been built into the LE1835 so that these CVs
can be reached.
