Thanks for recomendation. I ordered the st2000+ this am.It comes with its own bulkhead socket and plug, however my Standard Horizon cp180i has just a cable raw ended. Can you recomend a source for power/data cable marine plugs/sockets. I intend to link the DSC radio,Plotter and pilot together.
Thanks again, I think the ST 2000 will be a better choice. Richard.

PhilipStevens If you are going to upgrade your tiller pilot, I would advise you to go to the next model up, the ST2000+. The reason being that it is a "drop in" replacement (as is the 1000), has a quicker and stronger helm to helm response, has a digital display, and can connect up with either Seatalk or NMEA.

I have had both AH1000, ST1000 and ST2000, and would go with the 2000 in preference.

rvs I sail a 27ft Jenneau Fantasia. Tiller helm. I have bought and installed a Standard Horizon Marine DSC Radio m# GX1500s, also a new Standard Horizon 180i plotter. I want to replace a faulty Autohelm 1000 tiller pilot.
Q1 is the Raymarine st1000 the correct replacement tiller pilot?
Q2 Is it a drop in replacement?
Q3 will it configure to the above equipment

tap I have ST1000+ tiller pilot with a ST60+ speed/depth/wind system and a Garmin 76Cx GPS. Everything works fine. I can have the ST1000+ steer to a way point from the GPS or steer to the wind from the ST60 wind instrument. Or just steer a compass course from the ST1000+'s compass. I have the autopilot's status messages popup on the depth display.

Connect the Garmin's NMEA out to the autopilot's NMEA in (+). Connect the autopilot's NMEA in (-) to ground. The autopilot does not have a NMEA out, but there are two wires for the in because it is true NMEA 0183 and uses differential signalling. Connect nothing to the 76Cx's NMEA in (which is basically useless in the 76Cx). Connect the autopilot's seatalk to the yellow seatalk wire from your instruments. Connect the 76Cx's ground and 12V wires even if you plan to use the batteries in the 76Cx.

Make sure the ground is the same to everything. This means don't run anything that draws a lot of power on the same ground wire as some but not all of the electronics using too little gauge wire. The autopilot can use a fair bit of power, so make sure you used the proper gauge wire for it, or it won't have the same ground as the GPS or instruments.

GPS - Tiller Pilot - ST-60 Wind Instrument

I was able to connect my Garmin 76Csx ok to the Ray 2000 tiller pilot and it worked fine UNTIL I installed a Raymarine ST60 instrument package that would operate the tiller pilot from the wind instrument. Looked and looked for a solution to no avail until I called Raymarine. They said the Sea Talk from the intrument package to the tiller pilot would take precedence over the NMEA signal from the GPS. They wanted me to buy a NMEA - Sea Talk convertor for about $100. When I asked if I could simply put a switch in the Sea Talk signal, they said that would work as well. Haven't tried it yet. Has any one outh there had a similar issue? If so, how did you correct it?

nickmerc I had this same issue with my ST2000+ and Garmin GPS. I spoke to Garmin's help line and they were unable to solve the issue. Raymarine never got back to me. I spoke with them at the Annapolis Boat show last year and they said it must be an issue with the GPS. They never once mentioned the info you found. This has been bugging me for almost 2 years. Thank you.

amazing but..likely!

I have been struggling to connect garmin GPS to Raymarine 2000 pilot.

In Raymarine 2000 plus user manual, the connecting chart shows only two NMEA wires; my portable Garmin GPS has a cable with 3 wires. One is called IN one is caled OUT and the third is common. If I connect IN-IN OUT-OUT and leave common free the pilot senses nothing. So it is likely that your suggestion might work. My only question is how can the pilot perceive a voltage with
NO ground? Amazing! I agree that nothing should go from pilot to GPS; but the signal from GPS to pilot should be proportional to the ERROR; no voltage if set course=actual course; positive or negative voltage otherwise. But to detect a (say) positive voltage a ground is needed: positive respect to WHAT??

OK, FINALLY got it worked out! (Strange but true answer)

Thanks to yesterday's effort with the VHF's DSC connection, I had discovered / realized that NMEA 0183 is NOT a two-way network, but is instead two parallel one-way networks, sharing a common, well, "Common" wire. One wire is "Out" from a given device; one wire is "In" to that device, and one wire is a common (often erroneously called a "ground") conductor to complete BOTH of those one-way circuits. (Yes, an over-simplification, but one that provides a fairly clear image for analyzing.)

So, the "Out" wire from one device has to go to the "In" wire(s) of any other device(s). Conversely, the "In" wire from that first device has to connect to the "Out" wire of any other device(s). Then, the "Common" wire is, well, common to all of them.

HOWEVER, I also have discovered that some manufacturers, say Garmin, don't use three wires for 0183... they use two ("In" and "Out") and then use the 12VDC negative wire as the common conductor for NMEA 0183. Some, like Standard Horizon, use three wires.

I had been trying to connect the Garmin "Out" to the Raymarine "In" and the Garmin "In" to the Raymarine "Out". I assumed (ASSumed!) that Raymarine must be using the 12VDC negative like Garmin did, so the whole thing should work.

Of course, IT DON"T!!!

So, there had to be some other way to "close the loop".

That got me researching on Raymarine's web site.

Finally found it... "Connect the GPS units NMEA OUT (+) to the Raymarine pilot's NMEA IN (+). Then, to connect negative side, run a line from the Raymarine NMEA IN (-) to the GPS ground wire, or to ground."

The Raymarine just flat doesn't send ANYTHING to the GPS, so it doesn't even use its own "Out"; so, instead (and here is, to me, a VERY weird part), you just put a "Jumper" from the 12VDC negative pin to the NMEA 0183 "Out" pin on the Raymarine connector.

Works Great!!!

The really bad thing here is that I think I am beginning to really understand NMEA 0183!!!
