Hope that someone has fathomed this out...
I assume that I use two ports of the switchpilot, one for each sub-turnout but how do I wire up the three frogs to the two Extension ports?
Do I take a spur off the middle one and pair up to each of the other two?
following on… thanks to advice posted in reply, I have sorted out the above issue.
However, a new one emerges…
I use the ECoS system and the feedback method via the Extension modules. Now can only obtain correct feedback for two of the three point positions despite swapping over terminals. Is this just me or has anyone else found this ( and fixed it)?
