I am o-en to buying the n2k to usb converter, but actually not sure i need to!
My ais is the digital yacht ait1500n2k, which has a usb output as well as the n2k.
So i'm hoping to use that.
If the ait1500n2k doesnt multiplex the non-ais data onto usb then i could add a nmea0183/4800 inout from the b&G.
Frustratingly i wont see Amita for about 6 weeks so cant play with interfacing just yet.....
Does ayone have experience of connecting the ait1500n2k via usb?
I know digital yacht are supporters of signalk, and nice people, so maybe i'll ask them direct.

Looking through the AIT1500 manual from the DY site the first thing I note is that the USB port is not isolated and they don't recommend it for long term connection to a PC; they recommend using an isolated NMEA/USB converter instead.
Otherwise it looks like it might be capable of at least some multiplexing
Quote:A multiplexing feature is provided, which means any messages received on the low speed Input 2 port are automatically transmitted on the high speed Output 1 port. This is particularly useful when using a chart plotter having only a single NMEA0183 port.
