Default Raymarine S1/ST6002 and NMEA

Well, that's the way that I would like to think that it works, but I'm
still not convinced. As it says, "The SmartPilot control unit can
display SeaTalk and NMEA instrument data in a user-defined selection of
data pages."

I know that it can display the data, but I didn't think that the ST600x
controller converts it to SeaTalk. I just have this feeling that
RayMarine wants to see you yet another box to do the conversion, as
mentioned in the last bullet above (SeaTalk/NMEA interface).

I'm kind of getting lost here. I have a Garmin GPS connected via NMEA.
The S1 uses the GPS info to go to a waypoint or follow a route, and
displays the info from the GPS - goto a waypoint on the GPS, hit
"Track" on the S1, it beeps and gives a turn direction and course, hit
"Track" again and the S1 steers to the waypoint or follows the route.

The only connection between the S1 computer and controller is Seatalk,
so it must be converting NMEA to Seatalk.

I've been continuing this same discussion at SailBoatOwners.com,
http://forums.sbo.sailboatowners.com...136#post621136
which is a forum where there's actually reasonable discussions about
boating...

But, before I digress...the conclusion there is that the ST600x will
display NMEA data which is presented to it, but it won't translate those
sentences into SeaTalk format. Thus if you have another SeaTalk based
display on the boat, you won't see the data being fed to the ST600x with
the NMEA input. To convert NMEA to SeaTalk, you need a box which
bridges the two.

I'm not 100% sure what you mean when you say a "Garmin GPS". Are you
talking about a GPS antenna or a chartplotter? For example, I have a
Garmin GPS antenna which connects to my course computer via NMEA and I
also have a NorthStar chartplotter connected via NMEA and a RayMarine
chartplotter connected via SeaTalk. All of these talk to one another
and my ST6001 just fine. However, let's say that I had a wind
instrument connected to my ST6001 via NMEA. The ST6001 would show the
wind data, but my RayMarine C80 wouldn't display the wind data.

Is the NMEA signal from your Garmin feed (physical) to the ST6002 dispaly or
to the S1 computer ?

The Garmin GPS NMEA output is connected to the S1 computer. The S1
will go to a waypoint or follow a route, and display data from the
GPS. The display/controller is connected to the computer via only
Seatalk.

A Garmin _GPS_ the S1 uses to go to a waypoint or follow a route.

I don't have any other Raymarine instrument displays, but I have to
believe the S1 does translate NMEA to Seatalk because the Garmin NMEA
is physically connected to the S1 Computer, and the S1
Display/Controller, which is physically connected via Seatalk only,
displays the GPS data. So the NMEA data has to be available on the
Seatalk buss for the display to get it, doesn't it?

Rick,

The RayMarine S1 is a course computer. It has has no display. How do
you input the course to it? The ST600x and any other controller will
beep when it's time to change waypoints.

From what I can tell, your Garmin GPS antenna is connected to the S1
course computer, which is translating the lat/long into SeaTalk. There
has been no argument about this. The whole discussion has been about
connecting a NMEA instrument to the ST600x NMEA input and the ST600x
translating the NMEA data to SeaTalk. Your antenna is connected to the
S1 course computer and not the ST600x controller. What are you talking
about?

Geoff, one more time and I give up.

I have a Garmin Chartplotter GPS. It's NMEA is connected by wires to
the S1 Computer NMEA connector.

The S1 Controller (display) is connected to the S1 Computer by wires
via Seatalk. This is the normal setup.


The S1 Controller will display data from the Garmin Chartplotter, SOG,
COG, XTE, Waypoint name, etc VIA the SEATALK.

Goto a waypoint or activate a route on the Garmin Chartplotter. Press
the "Track" button on the S1 Controller and S1 does some flashing and
figuring, the beeps and displays the new course and to turn port or
starboard. Press the "Track" button again and the S1 changes course
and steers to the waypoint or route segment.

OK. So the S1 computer translate to Seatalk. We guess that is not the case
if you connect the NMEA signal to the ST6002 display.

Rick,

The issue here seems to be with terminology. You have a S1 course
computer (corepack in RayMarine terminology) and some form of control
head. There is no such thing as a S1 controller. You probably have
either an ST70, ST600x, ST700x or ST800x (where x=1 or 2).

The S1 corepack will translate the NMEA lat/long data into SeaTalk. Note
that if the GPS antenna was connected to the NMEA input on the
controller, that it wouldn't translate (or even understand) it. The rest
of your data (depth, wind, etc) is most likely coming from SeaTalk
instruments and no translation is required.

Actually, I don't see why not. I'd try it, but we're out cruising for
a bit and don't want to start taking things apart.

The way I understand the manual, it should. I don't find the manual
confusing or ambiguous. It basically states you can connect NMEA
equipment to the computer or the display. Sounds simple and
straightforward to me. Otherwise how could you steer by a NMEA wind
indicator, GPS or whatever?
