A brief history of BiDiB
Bidirectional data transfer was announced by the industry since 2004 and was successively implemented in decoders. First bidirectional feedback systems becomes available in 2009, but this systems had not been designed for a system-wide installation.
With the release of 16 channel feedback sensors on the market in 2010 (Blucher, OpenDCC) there was a strongly need for a common system bus. In long discussions a powerful and future-proof system bus was designed. This system bus is the succession from Tams RC-Talk after the system becomes available.
This draft contains concepts and structures that solves all other known system bus problems from other model railway vendors. Basically, the bus was designed as a feedback bus only but it has the potential to become the All-in-One system bus for model railways. Therefore, the design is constantly expanding to cover command stations, booster, accessories and control panels.
Once the system bus was running fine in the simulation and we were confident of the concept, we decided to build a test setup of interface and several different types of nodes in order to test it in the field.
At this point I would like to say "Thank you" for the constructive dialogue to 3 persons Mr. Tams, Mr. Blücher and Mr. Herzog that took an active part in this project. Also I would like to thank Mr. Fischer for the translation to English.
