Once we get the boat in the water I'll see if our E-80 works with a
regular
ethernet switch. But until they actually get around to shipping Raytech
v6
there won't be anything on the wire to packet sniff with Ethereal.

Yes, it's plain old ethernet. It connected right into a regular ethernet
switch using Raymarine's supplied cable. It appears to be sending its data
as UDP packets. Ethereal, running on the laptop, saw quite a bit of this
data while the E-80 was active. No idea where the packet data is
documented.
