I have a DCS100 Command Station/Booster and just purchased a DB210 Booster. I'm using Digitrax PS2012 power supply & PSYC52 power supply cable.On the DCS100 the two power supply input connections are simply labeled "POWER IN" AND "POWER IN" (no polarity indication).
On the DB210 the two power supply input connections are labeled + - BA (don't know what BA means).Do power input polarity connections to both DCS100 & DB210 have to be the same? If so, which is + & - on the DCS100?
Figured it out.
Common ground (-) connecting Command Station/Booster & Booster, not + & - to both
