The SE8c can take inputs from the LocoNet cable _or_ from the track DCC signal. It could be that it decided to use the track signal with LT wasn’t working. But I’m not sure why it would do that.

Strange behavior.... I just installed my first SE8C and during initial testing it would only respond to NT commands, not LT. It has since resolved itself. Wondering what would have caused this?
Summary of my of setup (it's a frankenstein lol).
NCE PowerPro command station
JMRI 4.17.3
Stand-alone Loconet with Locobuffer USB rev N.
2 BDL168s for detection
C/MRI connection running an Arduino that runs a servo and signal lights at one turnout
Tam Valley Octopus and Octocoder running 8 servos.
All this worked fine when I connected to SE8C to the loconet (and still does). When I first connected the SE8C it appeared to be working, except that the Digitrax test signal light would not change aspect when the correct LT turnout addresses were sent from JMRI. It just stayed Red over Red. I know the SE8C was properly connected to the loconet because I was able to read and write OP-Switch settings. The signal was setup in JMRI as LT turnouts and those turnouts were used to create an SE8C signal head. When I could not get the signal to work, I decided to connect a tortoise (SW address 01) and try it. By accident, I found it would respond to to switch address NT01 but not LT01.
This prompted me to send NT addresses to the signal heads and sure enough, they worked! But the story doesn't end here. I took the SE8C to my friends Digitrax layout to set the Board ID to 8. Back at home, I reinstall it and the now signals and tortoise no longer respond to the NT addresses. Instead, they correctly respond to LT addresses and not the NT.
Yes, it works fine now. But I'm the kind of guy who needs to understand why things happen to prevent future problems. Do any of you guys have any idea what could have caused this?
Any help, explanation or theories would be greatly appreciated!
