Thank you for answering me! Sorry to drag you off course. You know what the wiring is however, I didn't have a clue. I should have researched your profile to see you are in that club. I now get a good idea of what you're doing.
So just one more question to help get you a proper answer from the techs here. Are the TIUs hooked up with chokes?
OK 2 questions, how are the TIUs powered? the relay cuts the track connection and/or power to the TIU?
I have to confess that many years ago I tried passive mode. The signal was weaker and that was a big deal to me. So from then on I did not use it anymore. I never heard of anyone attaching chokes to restore the signal strength back then. There were no version L TIUs back then.
I am tempted to try passive mode again outside on my G scale. I never saw any significant power draw way back when I tried it with one TIU channel. The way you're club is wired, my info wouldn't apply to you here.
Hopefully a tech will bail me out here as I never heard of TIUs wired this way with relays for isolation. I'm tempted to guess at the reasons but it wouldn't help you here and now.
