Partial install of Raymarine EV-200 for only heading data?

[rgesner]

I have a new and not-yet-installed EV-200 Sail, which I bought as a spare to my older Raymarine autopilot, which is still working fine.

I don't want to install the entire new EV-200 yet, but I do need the heading sensor data to enable MARPA over NMEA2K for my Garmin radar. What is the minimum installation required to achieve this?

Can I install only the EV-1, power it from the ng Power Cable via the Seatalkng and connect the Seatalkng to NMEA2K with a DeviceNet Adaptor Cable and that's all?

Or does the EV-1 require the ACU-200 to also be installed (and configured?) to obtain the heading data?

Thanks - Rusty
