Evo 100 Networking Problem

Hello,

I am helping a friend configure his sailboat with Raymarine Electronics.

He has:
Evo 100 with P70 control head and Mk2 wheel pilot
I50 Depth
I50 Speed
I60 Wind

The Evo 100 components are connected to a 5 way Seatalk NG connector.

The speed, depth, and wind instruments are daisy chained together and then connected to a Seatalk 1 to Seatalk NG connector (I don't know why).

On the P70 control head I can run diagnostics and all the devices show up (I50 depth, I50 Speed, I60 wind, ACU, etc.).

If I try to search for a speed or depth source, nothing shows up.

Any ideas? I can provide screen shots, etc. if that helps.

Thanks,
Barry
