I currently have the lights-across-the-outputs trick working on my two existing older TIUs, which work wonders in boosting the DCS signal.
Just purchased a third TIU, a new REV L.
I understand the REV L TIU does not need the magic lights for a good signal.
If I put it as the first TIU without the need for the magic lights, do the remaining older TIUs still need the magic lights connected to boost the signal?
