I gave up on repairs and renewals and being charged for work not actually carried out on my Raymarine Wind Instrument a couple of years ago, and bought a NASA Wireless Wind instrument which was fitted to the masthead a couple of years ago. Apart from occasionally loosing the WiFi signal where I have installed the receiver inside the wardrobe in the aft starboard cabin on my B36(2002), the instrument has otherwise worked faultlessly and has withstood the storm force winds that last year hit Anglesey and dismantled Holyhead Marina with some spectacular vengeance. That aside, as I said it has worked as well if not better than I had hoped for. I know that the WiFi receiver sends an NMEA0183 sentence (MWV if I remember correctly), to its own display unit where it uses a cable consisting of red, black and yellow covered wire cores. My guess is that the red and black cables carry 12 volts + and - to the display instrument while the yellow wire carries the NMEA sentence. I would like if possible to connect these wires, one or more of them to my original Raymarine Seatalk system in order for it to feed into a Raymarine display instrument that has the ability to display one or other of the various feeds that link into the Seatalk system such as depth, speed or wind when the original Raymarine wind instrument was working (not very often !!!).
Does anyone have any hands on knowledge of connecting a NASA wireless wind instrument WiFi receiver to Raymarine Seatalk with any success. My Seatalk system is already powered with a 12 volt connection so I’m guessing that it won’t need an additional 12 volt supply from the the new wind instrument, so can I just connect the yellow data cable from the wireless receiver to the data cable within the Seatalk system ?
