Reply to "Should a TPC 300 adjust voltage on a Cab 2 in command mode?"

do you have your transformer set at 18 volts or close to it? reason I ask is my z-4000 is set at 18 volts at track and never varies if I turn the big red knob. so I will ask this do you address the tpc using remote as a tr-1or whatever number you have assigned to your tpc  then at bottom of remote push the L button then the tpc should show a slow led light blink this indicates tpc set for command operation. just thought I would ask if this is how yours is responding
