I have an E80 Classic/Seatalk system. I assume that the output from the depth/wind and speed transducers are just analogue voltage signals? Where do they become NMEA data - in the Seatalk or in the E80 chartplotter?

In the instrument.

Is that strictly true? I thought that the analogue or other transducer-specific signal arrives at the relevant instrument and that instrument (depth, log, or whatever) digitises and displays the data. The digital data is also coded into SeaTalk protocol and sent over the bus. It gets converted into NMEA in any device which has an NMEA output, and assuming that it's a piece of data which is supported for output and that data is also selected for bridging on to NMEA. Having said which, I'm not sure if any of the ST instruments actually have their own NMEA outputs; on my boat all the SeaTalk data ends up in the back of the RN300 GPS which then forwards selected highlights on to its NMEA output.

There was a long thread on this subject a couple of months ago.
My older ST50 Tri data repeater has a separate NMEA 0183, but the later ST60 don't, so a separate converter is reqd.
I will see if I can find the older thread reference.

I agree with all of that, given superheat's addition.

The ST60 graphic and multi both do though.
