Running My Locos
1. Power up Legacy Base
2. Power up Z-1000 brick
3. Select the track and press the TZV hotkey (S2) to turn off the  track voltage to that variable track.
4. Place locomotive on track
5. Power on Cab-2 remote by pressing "CTC" button
6. Press ENG and the ID number of the loco, ex: 4 1

 

I hope I got it right! Anxious to run my just purchased AFT GS-4!

Since you started out trying to run the conventional ballast tamper, you would be using the DCS remote to control that using the TR key to select the variable channel, then the TZV to turn off the voltage before placing it on the tracks.  You'd then run it using the thumbwheel to vary the voltage, the DIR key to change directions, etc.

In order to run the Legacy locomotives, you would not turn off the track voltage, you'd have the locomotive on the tracks before powering up and you want full voltage to run Legacy or TMCC equipment.  In this case, you would be using the CAB2.
