[CA] Trouble finding replacement for C80 MFD

[ddfour1]

Chuck,

I decided to go ahead and upgrade the auto-pilot at the same time as the MFD so I don't have to backtrack and get rid of the Seatalk-SeatalkNG conversion later. Two additional questions that have come up as I plan the updated installation:

1) Ok to use junction block D244 for the RS130 signal into the STNG backbone?

2)Everything I read in the various Ray manuals warns to only have one 12v power supply into a SeatalkNG network, but that doesn't seem correct. As planned, my SeatalkNG system would have a 12v supply for each of the following components: ACU200, Axiom9RV, SeatalkNG backbone, and Ray60. Can you confirm that all four 12v connections shown are needed and appropriate?

Thanks

Dave
