The tool for scanning the cab bus is on the NCE menu, Show Cabs.
So most people with a Power-Pro system use addresses like 50 and higher for
the AIU address. Each board or throttle must have a different number. When
entering a sensor in JMRI, you can use the shorthand of 50:1 for the first
pin of AIU addressed at 50. Just keep in mind that the AIU had 14 pins, but
the starting number works out to every 16 sensor numbers.
