Your artisens is spitting out a lot of sentences, however On your picture I see only some readable wind
and course data. Most of the sentences start with !PARLB, this is a private message type for the artisence and can't be read by O.
On your picture the far left side of the debug window is hidden. Every line starts with a timestamp. If you receive more then say 6 to 8 lines a second your reaching the limit of the serial
data capacity, this might give the artisense a data overflow.
What you can try is: Disconnect all instruments from your network, and connect them one by one to the artisense and check when it goes wrong.
