I have inherited on a new , to me , boat a Axiom 9 it also has a ray marine st2000+ tiller pilot. They should talk to each other, right. It was all 183 but now has a converter to 2000 with I think a gateway . Only the yellow wire from the st2000 goes to the gateway but the Axiom is not picking it up , any ideas how to trace where the yellow lead goes ?

What do you mean, "not picking it up" ?

The ST2000 has a single NMEA0183 input or a Seatalk input. You will not be able to "see" the tiller pilot from the Axiom, it will not appear in the list of connected equipment and you will not be able to engage or disengage the pilot from the Axiom. All you can do is to set the Axiom to "Goto" a waypoint, then engage the tiller pilot and set it to steer to that waypoint (from the tiller pilot).

The yellow wire from the ST2000 is Seatalk, not NMEA.

Might be able to get compass heading from the ST2000 to the Axiom with a suitable converter. It puts it on Seatalk1.

The ST2000 definitely puts out compass data on Seatalk1. I have it on my boat and it's the only source of compass data I have. I can pick it up on my chartplotter and also my home built Seatalk1 to Bluetooth bridge and then on to OpenCPN.

The ST2000 also responds to +-1, +-10 and autopilot mode transition (standby/auto/wind/track) Seatalk1 messages. I have made an autopilot remote control using those messages so I know that the ST2000 responds to them. With a suitable converter the Axiom maybe able to communicate those to the tiller pilot, although with a tiller pilot it's less useful as you still may have to walk over to it to connect physically the autopilot to the tiller.

What I don't know is what the Axiom puts out for autopilot control messages and whether any converter, Raymarine or otherwise, converts those proprietary N2K messages to Seatalk1. When I get one I'll get a canalyzer on it and see what it's doing.

It's not clear if the OP is trying to connect his Axiom to his ST2000 via a converter to NMEA0183 or Seatalk1. I would expect more functionality to work with Seatalk1. Exactly what he will be able to achieve I guess is a question for Raymarine if it's all their kit he's using.

The docs give no mention of this, but happy to accept it does. That being the case, if the converter converts compass data to N2K/STNG it ought to have that data on the Axiom.

That makes it a little annoying that the AP cannot be controlled from later Raymarine MFDs. Come to that, the Axiom won't fully control the new Evo APs, you still need to have a P70.

I suspect the Axiom won't even recognise the the ST2000, in as much as it won't control it, but it will send XTE etc to it. Not sure if you could make something to spoof the Axiom into thinking you have an EVO or something ?

In post #1 he says mentions 0183 and the converter, but says it's connected to the yellow ST2000 wire, which is Seatalk. Might be useful if he looked closer at that and also posts what it is he's trying to achieve.
 
Hi ya all, the boat is a motor sailor with a nice heater in the cabin . I want to be able to stick the pilot on the tiller. Go down below put the kettle on and watch for the dreaded 25lt drums bobbing about. Then if I see I'm heading for one give it 20 degs port or starboard without going out side. I thought that should be fairly straightforward. I think it was all 183 before the axiom was installed then the gateway thing was put in along with ais. It, the axiom picks up the wind depth speed from tack tick which I believe is 183. So I should in theory be able to set it to stear to the wind as well. Cheers

Your TackTick instruments will be outputting 0183, but you said they are connected to the ST2000 yellow wire, which is Seatalk. The ST2000 will steer to wind, but not to 0183 wind data from the TackTick display.

If you're getting TackTick data on the Axiom you must have something converting 0183 to N2K or STNG. If the yellow wire is connected to the ST2000, that's ST1, so you must have something converting 0183 or N2K/STNG to ST1. Impossible to offer any further suggestions without knowing what you have.

As for course changes from the Axiom, i don't think that will be possible, but if you look into what converters you have we can get it all connected up in the best possible way and confirm that. My feeling is it won't work. Angus mentions his home made remote in post #5, i suspect this might be your best option fr controlling the TP from the shed.

Yes, that's what I do. The design and source code is open source but I'm not making them.

Raymarine do a couple of autopilot remote control handsets that are Seatalk1. They are not cheap for what they are but will control the ST2000...

Wireless Remote Controls | Raymarine

I expect that they are near end of product life though and will be updated for STNG versions before long.
 
Thank you , you have lost me a bit but I'm pretty sure there is a converter will have to explore it in more depth. Do raymarine make anything cheap!
 
I think the easiest solution for you is the S100 remote control with its base station wired directly to the Seatalk pins on the ST2000 connector. It's only 3 wires and no converter needed. Fit the remote control's cradle next to your Axiom plotter inside in the warmth. Maybe Paul will provide his thoughts on this suggestion.

The S100 handset, cradle and base station pack is £337 from Marine Superstore. There's a new (but tatty box) one on ebay for £300. Beware of the cheaper ones on ebay that don't have the base station if you look there.

I'd agree with you. I'm almost certain that the Axiom won't control the ST2000, although a quick email to Raymarine wouldn't hurt, so spending time and money on converters might not be a good investment.

Would still be interested, out of curiosity, what the OP has by way of a converter.

No, they don't do much cheap, but do any "of them" ?

If you possibly can, have a closer look and see what converter/s you have, it will prove useful to know at some time, if not now.
 
If you want a simple and cheap remote control for your tiller pilot there is plenty of advice for fitting a 4 pole remote receiver with a 4 button fob transmitter. Its easy to fit the receiver board into the tillerpilot. I bought one for about £30 and with a bit of soldering had it fitted and working in an hour or so.
I can happily alter course for a pot using the plus or minus buttons on the remote fob or sit on the bow steering the boat whilst on dolphin watch. I very rarely set a tiller pilot to steer to a way point. I prefer to set it to an estimated course to steer!
 
The ST2000 using NMEA 0183 does not output anything and you cannot issue any autopilot control commands via it. It understands the following sentences so it can steer to a waypoint or to wind.

Cross Track Error APB, APA,RMB, XTE, XTR
Bearing to Waypoint APB, BPI, BWR, BWC, BER, BEC, RMB
Distance to Waypoint WDR, WDC, BPI, BWR, BWC, BER, BEC,RMB
Waypoint Number APA, APB,BPI, BWR, WDR, BWC, WDC,
RMB, BOD, WCV, BER, BEC
Speed Through Water VHW
Apparent Wind Angle and Speed VWR

I had trouble making the ST2000 work with wind when using it with a Garmin plotter acting as an NME2000 to NMEA 0183 bridge as it did not convert the NMEA2000 wind to NMEA 0183 VWR. I had to use an actisense converter on the NMEA 2000 network to do that. Also to make it work the NMEA+ on the actisense went to pin 6 on the ST2000 and NMEA- went to pin 5 on the ST2000.

Seatalk allows an autopilot remote (z101, or ST600R) to be used with the the ST2000 so you could have a mini-Seatalk network to connect up to a remote down in the cabin and do it that way.
 
There are a couple of cheaper wifi remotes than Raymarine. Try "Madman" (Australia) or " Seymo"(Spain), or easy enough to make your own.
 
I couldn't work out why this was still going , then saw the date of my original query, since did a refit and had to renew the steering so changed from wire to hydraulic and added autopilot...its a joy
