A friend recently purchased a Digitrax DB210 as someone told him he'd need one for his layout.

He's trying to figure out how to connect it to his DCC++EX base station.

Can he simply use the signals from his rails to feed the Loconet RailSync wires to the booster (he wouldn't need more than 5A, so the DCC++ rail outputs are otherwise unused)?  What about the 'ground' reference booster input?  I suspect that's not necessary as long as he's running just the one booster for the whole layout - unless he uses a PM42, obviously, or other Digitrax device that needs the reference.  Comments?
