Raymarine S1000 installation question

:?: I have just completed the installation of an S1000 on our 22 Cruiser.

Everything is working properly except the GPS navigation. I am getting a "No GPS FIx" error on the raymarine when I try to activate a track. Now I am sitting at the dock and not moving and have simply told the GPS to go to a waypoint.

Does the boat need to be moving for the GPS to synch up with the Autopilot?

I have a Garmin 182C and I spoke to Garmin and have installed as they instructed. Using only the positive TX / RX wires on the autopilot and grounding the 2 negative autopilot wires. I set the GPS communication to NMEA In/OUT

Just looking for some advice / confirmation from those of you that have installed one of these.

Thanks
 
I may be wrong about this but I believe I saw somewhere that you need to be doing about 3 Kts in order to get a GPS heading for it to work unless you have a Gyro compass input.

I don't have the manual with me so I can't verify that.

Your correct, I took another look and the Manual does state that you have to doing at least 3 knots. I just did a sea trial and I'm still getting the No GPS Fix error. I am not seeing the menu options that the manual describes either. I seem to remember somebody on the site saying the that the unit had to go through some sort of initialization but I haven't seen that. I'm going to contact Raymarine tomorrow and see if they can help.
 
It seems that when I installed Journey On's S1 autopilot, that it took a double ended signal, i.e., the low line wasn't grounded, there was a + & - connection. (RS432 vs RS232?) Again, it wasn't a S1000, but another Raytheon product.

Also, in setting up the Garmin, you probably have to select the NMEA sentences it outputs. The Raytheon manual will tell you what sentences it needs and the Garmin manual will tell you how to select them.

You might ask Raytheon about both the wiring interface and the data interface.

Good luck, interfacing 2 different manufactures can be hard and illuminating.

I have a bunch of experience with the "no GPS fix" error thru my insall of our S1000 last year. The problem is that your S1000 is not receiving the GPS signal or it is not valid. You'll be able to tell that the S1000 is getting the signal and all is good when you are at the dock and you get the "Too Slow" message. At that point the S1000 is getting the GPS signal.

Did you have to "create" your own wiring/plug from the GPS to the S1000? I did and had the input / output wires reversed.

One of the best additions to our boat - S1000.

Ditto what Robert has said. If you are getting a gps fix signal it will say "Too Slow" if you are not moving.

Look at the sat signals on the gps display. It may have a fix but may only be a 2d fix. I found that my S1000 will only operate if I have a 3D fix. I ended up using a gps with an external antenna for the best results.

I verified my wiring with Raymarine today, the technician told me that the only line the autopilot is using is the Orange receive wire and to ground the blue TX wire. I verified that the GPS is putting out a 3D signal. But still no luck I will check back with Garmin tomorrow.

Thanks for all of the advice it has definately helped keep my T/S on track
 
Looks like the NEMA output on my GPS doesn't work. I had Garmin tech support on the line while I was on the boat. He confirmed all the NEMA settings and wiring set up. There was no output voltage from the GPS for either port.

It's weird that everything else on the GPS works fine except the outputs.

I guess I will be shopping for a GPS now any recommendations?
 
Did you say you grounded the GPS black wires? My first installation connected the S1000 to a Garmin 182c GPS. I believe the wiring was:

Ray S1000 = Orange (+ ve in) to ==> Garmin 182C Blue (NMEA Rx +)

The Garmin Black was grounded and the Ray Blue was grounded.

Make sense? Is this how you had it wired? Also, what type of connectors are you using? Does the connector require you to strip the wire first? This is the problem I had at first and after stripping the wire, everything worked out great!

One last thing. Be sure the little emergency cut-off switch is untwisted, allowing the signal to go through.
Good luck.
 
Yes that's exactly how I have mine wired as well.

AP Orange to GPS Blue tied together
GPS Black and AP Blue grounded

I have stripped the wires and right am using a small wire nut to hold them together. Once working I will probably use a crimp connector and heat shrink to seal.

I twisted the cut off switch until it popped out and The Autopilot steers manually with the remote. I thought power twas cut to the entire unit if you activiated the switch.

Will the Rayarine work at all if the cut off switch is activiated? If so I could have switch problem. I can jumper it out of the circuit and try the GPS without it. I'll make some tests on this today just to be sure.

Thanks again for the suggestions.

When I push in the cut off switch it stops the unit from being controlled by the remote. When it's twisted til it pops out that is the on position and allows you to control from the remote. When the switch is pushed in the remote is still on but has no control over the pump. When I do use the cut off switch and reset it I get a signal "unit innitiating" on the remote after about 20 seconds it returns to normal operation. When first using the remote I sometimes have to toggle between standby and pilot several times before it takes over control with the remote. Hope that makes sense.
 
If your gps is putting out sentences then you should be able to detect the very recognizable voltage pulses metering across the the 2 wires with a multi-meter (should be about 1 volt ish).

Doesn't solve your problem but will definitely isolate the problem being with the gps output.
 
The plastic twist on/off switch for the power supply to the course computer wasn't acceptable to me, so I replaced mine with a bronze framed on/off switch. Much better.

I don't think anyone mentioned the 4800 Baud rate necessary for the s1000 system. When I linked my s1000 to a Garmin 741xs I had to carefully follow the manual for 0183 sentences, baud rate and NMEA settings. Doing this turned off my NMEA 2000 devices that were being fed.
Then I discovered that:
Unlike most products supporting NMEA 0183 communications protocol, many Garmin units ( mine is a 741 xs + chirp) use the power/data harness power ground lead to also function as the NMEA 0183 signal reference, so the black ground wire serves as a ground AND a NMEA reference. Connect +ve Transmit to +ve in ( blue-orange) signal connection, then go to grounding.

My Solution: I connected a Raystar 125 by Sea Talk to the data cable of the s1000, which isolated the 0183 system. All is well, alas. [/code][/quote]
