Hi there, I've just installed an axiom 9 RV in my sailboat and would like to tie my Comnav 1420 Autopilot in. It is of course, nmea 0183, so what is the best way to get this done, just a simple conversion such as the Actisense NGW-1?

Thanks

Hi iRondo

Thank you for your enquiry,

You are correct, the Actisense NMEA0183 to NMEA2000 interface would be the way to go - make sure that you use the standard version and not the one for AIS which uses a much faster data rate.

Awesome, thanks very much!

Cheers

You're welcome.

I'm about to do this same thing and I'd like to clarify the cabling. I'm replacing a RL70C Plus Pathfinder display with a Axiom Pro 12 RVX. The current display feeds the ComNav 1420 heading data over NMEA 0183. What cable / output should I use to connect the Axiom to the NGW-1? I assume that I connect that to the ComNav 1420 directly?

Thanks,
BD

Hi BD,

Thank you for your enquiry,

You mention heading data is required? Do you mean heading or GPS Data? If you require heading, then you need compass data from soemwhere - like an autopilot, however, if you need GPS data, then this can be sourced from the AXIOM 12 PRO.

The AXIOM 12 PRO has an NMEA0183 input/ output, ( the AXIOM does not have this), therefore the AXIOM 12 PRO can output NMEA0183 GPS data directly to the ComNav device.

Thank you. Yes I meant gps waypoint data. I'll update my diagram with your new information.

Thanks much!

Shoot I missed something. The GPS was feeding the old plotter using 3 prong SeaTalk. I think I can plug that SeaTalk connector into one of the two SeaTalk connections on the ST60. The other will be connected to the ST to STng converter. This should power the GPS and provide the data to the MFD via STng. Is that correct?

Thanks

Hi BD
It sounds like the GPS is outputting SeaTalk, in which case the GPS can be connected to any SeaTalk connection, such as the spare connection on the ST60. the GPS data will then be carried Via SeaTalk through the converter to the MFD.

Thanks
