Greetings!
?
I am still in the design stage for my layout, and am looking into the signaling options.
?
As I understand it, the central computer only tells a signal decoder to show an allowing aspect or not, and it its up to the decoder to determine which aspect is applicable, using status messages it has heard over the LocoNet/LCC. A signal decoder also can broadcast its new state whenever it changes aspect.
?
I have three questions:
1. Can the central computer instruct the decoder *which* aspect to display or is it only a binary go/stop order? If yes: how many different aspects can be ordered?
2. When a decoder broadcasts its new state, does it specify *which* allowing aspect it is showing, or is it only a binary go/stop? If yes: how many different aspects can be communicated?
3. In many signaling systems, a signal can give a proceed aspect for a train movement or a shunt movement. How does the central tell the decoder which of these to use? (In the signaling system I am modelling, shunting is governed by separate lights, which may be intergated into the main signal or be part of a separate dwarf/shunt signal.)
?
Thanks in advance
