This is not a problem in itself but may be contributory to 1 above if it thinks the helm is in a different position to reality. I have a friend with an identical system and the ram runs smoothly in and out, as does the previous SPX pilot and the ST2000. The ram does not run smoothly in and out as it should, it judders a lot when on standby and pressing +/- 1 or 10.

Not great as I need a pilot I can rely on when single-handed and down below - possibly sleeping.Ģ. Putting it on standby and then auto only fixes the problem temporarily. The only option is to switch the whole system off and on again. sometimes it sails off course with the helm centred, it does not correct, it then tells me it's off course on the control head then the off course alarm sounds on the control head (P70) but still it does not attempts to correct the course. There were also a number of Autohelm/Raytheon Chart Plotters and the popular Pathfinder range of MFDs (RC530, RL70, RL80C, etc.) that all had NMEA Outputs, that would transmit the SeaTalk Instrument data. Here is a diagram showing the pin out of the Pathfinder and Pathfinder+ unit’s NMEA OUT Cable.Click to expand.I have had various issues since installing, some have been ironed out or improved by tuning the system to the boat however I still have two fundamental issues to resolve.ġ. Originally the Autohelm ST50 Tridata and Multi instruments had an NMEA0183 Output and this was also true for the ST50+ range – for an ST50 or ST50+ instrument here is the wiring diagram:īy the time the ST60 range was released, the only instrument to have an NMEA0183 Output was the Multi instrument and when the ST60+ came out just the Graphic Display instrument had an NMEA0183 Output – For ST60 or ST60+ instrument, here is the wiring diagram.įor Raytheon Chart Plotters (RC530, RL70, RL80) Take the system below, most Multi-Function Displays have an NMEA port on them or perhaps the system has one of the SeaTalk to NMEA interface boxes (P/No E85001) which has an NMEA Ouput or an RS232 Output or you can also add our SeaTalk to NMEA converter, either of which can be connected to our WLN10 – Here is the wiring diagram for the SeaTalk to NMEA interface.

Our WLN10/WLN30 cannot connect directly to a SeaTalk network but there are usually one or two NMEA0183 outputs in the Autohelm, Raytheon or Raymarine system where our WLN10 can be connected to. After NMEA0183, this is probably the most common network found on boats and there are still tens, possibly hundreds of thousands of boats around the world that have a SeaTalk network onboard. Autohelm, the UK autopilot and instrument manufacturer who were bought by Raytheon in the 1990s and then evolved in to what is now Raymarine, developed their own instrument interface called SeaTalk.
