Topic 0409061 - Asymmetic DCC signal

September 6, 2004

There are places on a model railroad where localized information needs to be transferred to a locomotive, e.g. e.g. to stop a train automatically at a certain place. This topic is an attempt to develop a common specification for doing via an asymmetric DCC signal. This is a signal where the positive-going part of the waveform has a different amplitude from the negative going part. A decoder can detect this difference and act on it.

This is intended to be an optional capability that can be implemented cheaply, and independently of the command station.

Reinhard Mueller will coordinate this topic. As there are already implementations on the market, with more expected, this topic should move quickly.
