Power for SeaTalk Network in the Absence of an Autopilot

[Dockhead]

I replacing nearly my entire electronics on board with a new NMEA2000 system. However, I am planning to leave the old Raymarine wind and depth instruments as backups -- I will have extra holes in the scuttle anyway, and they work perfectly.

The instruments are ST60+ and they get their power over the Seatalk network from the autopilot. But I will be removing the old autopilot. Is there another way to feed them power?

Just power the sea talk bus on the autopilot side as if it was coming from the autopilot. Remember to fuse and switch this power supply. Check the raymarine web site if you are not sure about which wires to power.

Power to red and black. Yellow is the data line.

I started off daisy chaining my ST60s but it didn't work properly until I supplied power (and return) to both ends of the chain. No problems since.

My ST60 speed and depth just run on there own 12v feed from the DC panel. They are not connected to my AP. There must be a manual on the RM site. Good luck- I am enjoying reading of your new electronic suite. BTW, IIRC you were interested in a close-hauled wind display as well as a "regular". The RM i60 series has both according to binnacle.com

Thanks, guys! That makes sense now.
