Capen" Fellow listers, My UPSAT SL30 outputs both converter and resolver signals for an external CDI. That and my GX60 are switched through the ACU for input to the whatever brand CDI. I have a NSD-1000 HSI that I am installing in the panel of my RV6A which takes both of these signal types - this is intended to be the primary CDI. The Narco NAV122D/GPS that I have will also take these signals as inputs. The instructions for my SL30 indicate that the resolver signals need to be calibrated and should not be switched. These instructions also state that supplemental CDI's should use converter signals only. I'm trying to understand the functionality provided by these different type of signals.... Are they complementary - or similar in functionality? Can one set of signals be used without the other? Thanks, Ralph Capen Soooooo many little wires
