Apologies for another Seatalk question, I know there was something similar recently.
My aged Raytheon Raystar 390 has given up the ghost and I'd like to replace with something similar, at a less than Raymarine price . . The GPS can drive the Raytheon Autohelm 7000 (and I have Raytheon instruments elsewhere), so needs to be compatible - this means Seatalk I guess. Does it?

I am a bit nervous when it comes to electronics stuff I might get wrong, so any suggestions / advice would be gratefully received. Thanks.
 
Don't know if it helps at all, but the Raystar 125 GPS from Raymarine that I installed can be linked to Raymarine equipment as either NMEA or Seatalk. I would therefore suggest that any GPS sensor could be hooked up to Raymarine via NMEA.

(The 125 is around £200 to buy)

Can you tell what the Raystar was linked to? In other words can you trace where any Seatalk or NMEA cable connects to? Are they both used/exist?
 
Im pretty sure that if you feed GPS NMEA data from any opld GPS in to your ST7000 then it will be output on the ST bus in Seatalk automatically. Check the manual.
 
Thanks for the replies so far. Specifically, I'm about 750 miles from Grehan, the GPS and the Raystar manual right now so I can't check out things. The GPS is 'connected' into the rest of the Raytheon/marine instruments including the autopilot, and so its positional data is used by them. I just can't remember what the connections into the back of the Raystar are. One of them's power, I had assumed the other was Seatalk. Would it be NMEA as well? Sorry to be such a dunce.

[Edit] Not Seatalk . . .
OK I've done some delving. The data out socket is a three pin NMEA 0180/2/3 type. So I could just plug that existing plug into a new GPS with an NMEA output socket, could I? Simple as that?

My ST1000+ Raymarine autopilot receives NMEA data from my Raymarine Chartplotter but DOES NOT output NMEA data on the seatalk network. Also vice versa, any data received on the seatalk bus IS NOT output on via NMEA.
I know this as fact as I do not get any GPS data on the seatalk bus. I guess its so that Raymarine can sell more of their Seatalk / NMEA protocol convertor boxes at £100 each !
What a rip off !
Hope this helps,
Matt.
