Hi Mogens,
a user asked how to setup and configure the new 4-aspect-signal of Marklin and got it explained by Gerd Boll (also WDP-Beta-Tester), BUT: This only works with the German Version of WDP (V8.5).
The International Version of WDP V8.4 does not support the new Marklin 4-aspect-signals due to the fact that the signals did not exist when we released the International Version of WDP.
The 4-aspect signals will be supported directly in V9 for the International Version. This will happen around 1st or 2nd quarter of 2005.
In the meantime you can use them by configuring a three- and two-aspect signal in your layout like in the past.
Regards
Rüdiger
