The DCC80 Autofrog is a simple switch that automatically changes the frog polarity on your DCC layout. Allow us to introduce you to the Autofrog. Wiring the DCC80 is simple. There are three solder connections on the board, 2 connections labelled “R” - which you should connect to your rails or your bus and 1 connection labelled “F” which you connect to the frog input wire.
