DFF1 working but not displaying numerical depth Navnet 3d

[tristanmortimer]

I recently fitted a used DFF1 to my NN3D. The sounder is producing a bottom trace but the numerical depth is not displaying a figure. I'm sure that it has worked but what can have happened? Any clues appreciated.

Go into the installation wizard and confirm the DFF1 is selected as your sounder source 1st, next I would proceed with the instructions on setting up the data box is set to display depth. See pic below
