I have an important question about those using the Light-It as a signal decoder and having trouble.
?
Can you test, or have you observed, signals changing in parts of the layout that should not be getting any commands addressed to them?
?
Also, about the logic these people are using: Is a change in a single block causing a change (directly) in an signals not directly protecting that block? A signal changing in response to seeing another signal change is considered for this question to not be a direct change cause.
