when there is wiring problems you will get "Mapping pending" and it will not go away.
open the SLC loop so there is only a few devices and see if the Mapping pending problem goes away.
if so add devices until you find the problem, loose smoke head, maybe the feed to a base is miss wired.
take your time and look at each device, you will find the problem
