Axiom/Quantum Doppler Workaround.

I raised this issue in a post 12 months or so ago and though there were some helpful answers, I haven‘t yet resolved the issue.

I installed a Quantum Doppler radar and an Axiom Plus Display running alongside my existing E80 Classic Chartplotter/S2 Smartpilot. The intention was/is to upgrade the E80 at some time to a plotter that can be networked with the Axiom and change the Autopilot to a compatible unit but I boat to budget and this isn’t going to happen this year.

At the moment the Axiom provides a standalone Chart & Radar functionality. It is connected to the E80 via a NMEA/STNG1 Converter and displays Speed/Depth and Wind Direction as well as AIS data from my Class B Transceiver.

I would like to better utilise the Doppler and MARPA target tracking capabilities of the radar but this requires a heading sensor that is fast enough to respond to quick changes in direction. The Fluxgate compass that the S2 Smartpilot currently uses half works but isn’t good enough.

I have an EV1 heading sensor that is fast enough to allow this but it is incompatible with the E80 and at the moment, not wired into the the system. Is there anyway I can feed the signals from the EV1 to the Axiom but stop them reaching the E80/Smartpilot?

I feel that an Actisense Gateway may provide a solution but both Actisense & Raymarine are sitting on the fence….?

I'm not sure which autopilot computer you have but I understood that it would prioritise its directly connected fluxgate heading sensor rather than one that's connected via NMEA or Seatalk

And I've just re-read your post and you have an S2 as described within the screenshot from the Raymarine forum.

OK, thanks for this. I am not sure what I am doing wrong but I will have another go when I am next down and report back. Thankyou
