This post will probably end up embarrassing me one day, looking back, but I am often a bit confused when programming my PowerCab! Just the other day while attempting to speed match two AZL4 equipped loco's I was changing CV's 2-5-6. Program track. Every so often the programmed CV's game back different on recall? This happened about 20% of the time, eh, maybe I'm losing it. The recall feature eludes me, sometimes both loco's are there, sometimes not. My mind played tricks on me. I played tricks back. Then when programming the consist I could not get an old style to run well, so I went to advanced style. I know it is supposed to say "con" with a consist but sometimes it said "loc", but ran as a consist. As I repeated programming steps (with manual in hand) I saw everything from the headlights and tail lights on the lead loco only operating, properly in fwd and rev, to the headlights and tail lights on the rear loco only, to the head lights on the lead loco and the tail lights on the rear loco operating (I liked that). Dementia setting in early? In the end I don't really have a solution. I did start to cycle power to the PowerCab after almost every programming cycle. Which led to much more reliable results, but loads of power cycles. And I am happy to report that once I got everything the way I wanted it The PowerCab holds those settings day after day. Maybe a good rule of thumb is to cycle the power whenever you, or your Powercab, gets confused? Just wondering.
