I tried but couldn't get the Digi wi-sp to work
with rs-422. The converter solved
it and I am not unhappy. As a plus I can plug
in my handheld gps
through the serial
cable to the Digi and IPad
without any fuss.
Just took a look at the DigitalYacht WLN10 and it looks like it supports only 4800 k - ?? which would not work
with most/all ais devices - certainly not the Furuno FA-50.
Nice AIS display on iNavX
by the way!
