Connect the two red wires of the AD520 to your DCC output from your
booster and the two yellow wires to the section of track for the
reverse loop. You must double gap the track at the isolation points.
If the reverse loop uses the same turnout for entry/exit you can use a
switch/microswitch that is operated when the turnout is operated, thus
saving the use of the AD520 for something else like a return loop, a
wye or a turntable.
The turnout has to be operated to turn a train, so this
same "operation" can operate a switch/microswitch/relay etc.
