Light signal decoder Swiss dwarf signals

Dwarf signals are used for control of shunting operations.
Get Adobe Flash player Decoder of the Z1-series (standard and all-in-one classes) are the actual light signal decoder of the Qdecoder. Before using them on the model railway, they need to be configured. In the simplest case this is done with the programming button. However, often an additional programming with configuration variables is required. If signal aspects should be displayed, this programming can get an extensive job.


You can manually configure the decoder yourself, or you acquire a pre-configures Qdecoder-light decoder and save the configuration of the configuration variables.

A Qdecoder-signal aspect generator for two dwarf signals and a package of three Qdecoder-signal aspect generator for eight dwarf signals is available in the light signal decoder shop.
