Via aggiorno su questa interessante questione.
la ESU risponde:
you could try to swap the C and D connection between ECoS and booster, but I'm not very confident in this solution.
I'm pretty sure we haven't changed anything on CDE for ages, and since most of it is hardware, we couldn't change anything at all. The boosters seems to be dcc only. Try to switch all other protocolls off in the ECoS.
You could try to use the tracksniffer input of your booster, but I'm not sure how it will react to RailCom, so you probably have to turn it off in the ECoS.
A parte che sembra una barzelletta, secondo voi ha senso provare a spegnere il protocollo M4 nella centrale e riprovare il collegamento CDE? Se così fosse non potrei usare le loco della TRIX con questo booster
