I have a C90W chartplotter in my Beneteau
which also has a "PC interface" (NMEA to RS232
adapter + RS232
to USB adapter) below decks. Transforming my laptop (running RNS software) in a second chartplotter seems very interesting. Reading the manuals
it looks like I have to possibilities:
a) I can connect the USB cable from the "PC interface" to one of the USB ports
of the laptop.
b) I can use a Raymarine SeaTalk HS special cable for a direct connection between the C90W and the ethernet LAN port of the laptop.
The possibility b), being faster, seems much more interesting as I assume that maps, coming from the Navionics card on the chartplotter, would be available more rapidly in the laptop. Still I could not confirm if a wireless version of b) is possible. I understand that it will not be as secure as a wired connection but I really would like to be able to get navigation
information anywhere in the boat. In fact I really do not know if SeaTalk HS is like Ethernet. And then, if a normal wireless router could be used to provide connectivity between the chartplotter and the laptop.
Many thanks for any views on this matter.
