[TG] Controlling a SmartPilot S3 with Axiom 9

RE: Controlling a SmartPilot S3 with Axiom 9
Hello boxxy,

You can send navigation data from an Axiom to a previous-generation autopilot, but cannot control it (as in, switch pilot mode or do calibration.) Secondly, no MFD (of whatever generation) can act as a standalone pilot controller for that generation of pilot, they always had to have a dedicated pilot controller in the system in order to go into Auto/Track mode.

If you're crossing the Pacific short-handed though, my strong advice would be to consider a lot more redundancy than just the pilot controller. I would advise a complete, fully-installed backup pilot with a single On-Off-On changeover switch. This isn't necessary if you have a reasonable crew, but if the idea of hand-steering to the next port-of-call is not a pleasant one then I would put serious thought into it. The drive unit and course computer, as a mechanical part and a device which handles large amounts of current, are probably at least as or more likely to suffer failure than the display (which is little more than a screen and some buttons), and if the pilot is ST290-vintage then it's probably rather more than 10 years old and I hate getting calls on sat-phones from people who are two-up a fortnight from port with a failed pilot and no backup.

Finally, on the Seatalk and SeatalkNG wiring: if you still have an ST290-vintage pilot and ST290 instruments then you probably need at least Seatalk1, Seatalk2 (between the ST290 DPU, the Graphic and other ST290 components, and SeatalkNG with the Axiom and perhaps the i70s. It's a messy system, but I'd need to know exactly what components you have in order to make any specific recommendations about tidying it up. Can you draw me a wiring diagram for how things are now and attach it to a reply?

Regards,
Tom
