Garmin 740s and raymarine x5 wheel pilot connection

Just about to purchase a new raymarine x5 wheel pilot w/p70 head and a garmin 740s plotter.
Has anyone tried to connect these 2 units to each other yet? How did it go? How did they work together?
Thanks!

jsaronson: Do you need a control head in that configuration, or can the e7 do the job?

I used the p70 control head. I think one is necessary.

This should work. The Garmin has NMEA out in the power/data cable(besides NMEA 2000), just connect one of the NMEA outs to to the NMEA in on the course computer.

Re: Garmin 740s and raymarine x5 wheel pilot connection

jsaronson -- Have you completed your project yet? I'm looking at doing exactly the same thing only with my with existing X5 wheel pilot my Garmin GPSmap 720. I phoned Raymarine technical support and they said that the X5 course computer is NEMA2000 "compatible", but not NEMA2000 "certified". The tech support guy said the GPSmap and course computer may or may not communicate.... I think you'd have to look at the NEMA sentances for the X5 & GPSmap and see it they are the same.

In any case, you're going to need to construct a Seatalk NG backbone. You won't be able to just plug the X5 directly to your GPSmap 740. Best to use a Seatalk NG 5 way connector with terminators. I would connect the p70 to a spur (white) connector, connect the X5 course computer to a spur (white) connector and thern connect the GPSmap 740 to a spur (white) connector. You can use an adapter cable to adapt the GPSmap 740 DeviceNET connector on the back of the GPSmap 740 to the Seatalk NG 5, these are available at turtlemarine.

But, according to the P70 manual, the X5 course computer will power the setalk NG network. However, it you read the X5 manual it states that the course computer does not power the Seatalk NG network..... if the course computer doesn't power the Seatalk NG network, then you will need to expand the Seatalk NG backbone and add in a additional spur running to a 12V DC power supply. You would need another 5 way connector to do this the easy way.

It's really a shame that Raymarine couldn't just use Nema 2000 instead of thier propriety Seatalk NG. Seatalk NG is NEMA 2000 (from a power & comms point of view), but the cable connectors are different than DeviceNET connectors which are used on other equipment including Garmin. Also, it seems Seatalk NG uses some proprietary "NEMA 2000" data sentances which are only read by Raymarine products and it's possible the X5 has these Raymarine specific data sentances (I know Garmin have thier own data sentances running on NEMA 2000 protocol as well).

Hope this isn't too much information, I don't mean to confuse things, but I've spent way too much time deciphering this subject. The world needs a Raymarine / Garmin rosetta stone! I'd wire the system first to see if it all works before you start drilling holes and running wires through bulkheads. By the way, the X5 and GPSMap are both great products in thier own right, the GPSmap especially. Thanks, Mike

Re: Garmin 740s and raymarine x5 wheel pilot connection

mine works great! seatalk NG is NMEA 2000, just with smaller cables. As I said, you need a NG to NMEA 2000 male cable available from Defender. Then build a NMEA network. You do need a 12 volt connection into the network.
Three tees. two terminators, a NMEA cable from the GPS to 1 tee, 1 for the 12 volt input and 1 for the seatalk cable.

Update:

So far, this is a no go. The 740 chartplotter and the garmin gmi 10 wind and depth/speed transducer all work perfect. The x5 /p70 however does not recognize the garmin wind data, nor does the chartplotter notice the autopilot.
I have all of this connected through a Nmea 2000 backbone. I have not gotten very deep into the configurations yet, but out of the box the two systems don't seem to communicate with each other.

Re: Garmin 740s and raymarine x5 wheel pilot connection

I am interested connecting my Garmin 740 to my recently installed SX5 WP and am unsure of the power issue that you mentioned. Right now the WP is hooked up and working fine with a 5 way connector which includes a power cord. If I remove the power cord from the 5 way and replace it with an Raymarine to Garmin adapter drop cable from the 740 how do I get power to the backbone and the SX5?

Re: Garmin 740s and raymarine x5 wheel pilot connection

You can link two of the 5-way SeatalkNG connectors together using a backbone cable (blue and black, $20-$50). My SPX5 came with 2 5-way connectors for this reason.
