Norfolk and Western position light signals can be connected to the Signalist SC1 as in the below diagram. A second single head can be connected to terminals E,F, G and H when a single head configuration is required instead of A, B, C and D.

Note that when using the CV38=8 configuration flashing aspects can be achived by toggling between the solid aspect and dark. Software such as JMRI will do this automatically.

N=Normal or Closed, R=Reversed or Thrown

In JMRI use DCC Signal Mast Decoder for CV38=67-71 and 129, use Quad Output for each positon light head when CV38=8, Double Output for each red/yellow/green searchlight head when CV38=8 and Triple Output RGB for each red/yellow/green/lunar searchlight head when CV38=8.
