Interfacing Wireless Wind Instrumentation

Hi, I'm presently trying to decide on whether to install a hard-wired or a wireless wind sensor on my yacht. The only real problems I have with a hard-wired system, is the potential for water leaks and interference with the internal halyard system. My boat has a top tapered section mast and below the hounds approx 80 OD size. Can I insert a tube internally to contain the cable?

Should I go the wireless route this might interfere with the DMK Box wireless? The mast is approx. 8m high and may work with a Bluetooth type of transmitter?? The other questions I have, relate to the extra hardware needed to run the wireless wind transmitter and to ultimately interface to the DMK Box??

Thanks guys

    Here is a photo of someone's site who is experimenting with interfacing. It's interesting to note that they have a 2 step hardware chain to get wireless Raymarine Micronet ( latest generation gear) to convert to NMEA0183 for export to the DMK Box .... Your comments please??

    That is a great photo I have not seen before but it is a great example of how versatile the box is with different inputs. In that photo the box is connected to Seatalk, NMEA 2000, and two NMEA 0183 ports inputting AIS and a instrument streams. I don't see the two step hardware chain but would love to get the authors insight into what instruments he is inputting to the box using which protocols.

    With regards to your first question, I'm not sure how best to counsel you. Many times a mast will have a tube already in it to run wires through and protect from chaffing. If it is a modern European mast like a Selden, or Z Spar, the top caps can be removed to access the tube. This is tough and perilous with the rig up but can be done or is relatively easy if the mast is removed from the boat. A wireless unit like the Raymarine can save lots of hassle. Our box only can input data through wires and cannot work with Bluetooth so a wired interface box like the one pictured is required.
