As long as you are setup for Ground wind, from what I read; you would require boat movement (speed). Have you tried it while moving the boat?
Thank you for the information! Yes we have tried it while the yacht was underway and it did not work. We delved into it further last night.
The system is getting true heading HDT from a STD22 gyro and water speed VBW from a DS80 doppler log via a Actisense NDC-4 then input to a Actisense NGW-1. The heading info displays fine in the system, however the water speed is not displaying (STW) and we think this is the problem. Although the Actisense NGW-1 does convert the VBW sentence into a PGN (130578) it is not accepted by the FI-70.
So now we are looking into a VBW to VHW converter, which are expensive.
Any and all thoughts or suggestions are most appreciated!
Kind Regards,
