i got confused now, my track is powered by the 7042 now, i use the analogue and the digital mode, both are working just fine now., i doubled all crossover turns and made the surgical cuts on the lanechangers turns and straights. My power booster cables are all applied in such a way that the analogue mode has no short circuit... the pitlane comes back to the same lane as it started with.... Will the ARC PRO work or still not ?
