replaced raymarine c80 with simrad go 9... not sure about some cables...

[liv2ryde100]

2005 340 sundancer. had original raymarine c80 and radar. thats all i had displayed on the chartplotter only radar and charts. no engine data or anyting like that. the boat does have the smartcraft lcd screen on the dash for engine data. so i assumed this swap out would be pretty straight forward. but when i pulled out the c80 it had two data cables going out somewhere. one is called seatalk and the other looks like some kind of old school nmea 2000 cable maybe? anyone have any ideas where these other connections go to ? maybe i can get engine data through one of these connections on the new screen? thanks so much if anyone has any experience with this

So NMEA 2000 is not old school and is very current technology. Seatalk is old school NMEA 0183 and SeatalkNG is basically NMEA 2000, with Raymarine priority cables.

Past that, you will need a Smart Craft to NMEA 2000 adapter to get engine data on the N2K bus, then if your MFD supports engine data, it can be configured to display that information. Many threads in this forum on that subject.

As for the cables in question, please post pic's of the cable ends, other wise it's just guessing what you have.

Ok I’ll take some pics thanks so much

The individual cables are likely your original depth or speed connections. I just pulled a ST1 set of instruments out myself and some stuff is transmitted over the ST bus but the depth, temp, and speed were all over individual small wires. I think they were blue, yellow, brown, white, and gray.

Thank you I’ll take a look tomorrow, I never had depth data on there but I have depth on my smartcraft lcd screen. There was def a blue and yellow wire, not sure about the other ones

Your seatalk cable likely connects your gps antenna on the arch to the display and may also output position data to your vhf radio if you still have the original raymarine unit. The other data cable is likely NMEA 0183 data out to your smartcraft system to bring data such as waypoints and speed into the smartcraft system.

The seatalk cables will no longer have a use in your new install but the NMEA 0183 can likely be reused to get data to the smartcraft. You can also tie your radio in to this for position data if needed.

C80s are capable of limited NMEA 2000 data for engine Info but must be connected to an engine gateway via the seatalk 2 port on a dedicated NMEA network that contains only engine data. This isn't commonly hooked up.

If you want engine data on your new display you will need to install a NMEA 2000 network and connect this to your smartcraft via an engine gateway. There are a few out there but the most cost effective gateway I've found is one made by a company called yacht devices.
