Serial Port Isolation

[wind_magic]

One of the potential challenges I have is that I have a lot of things wired together via RS-232 (or other) serial connections and this creates quite a web of potential ground loops and also makes the entire electrical system vulnerable to problems. What I would like to do is start opto-isolating some of these connections, especially connections that run up the mast (anemometer, etc), so I am curious - does anyone here have any recommendations for isolating serial lines ? Component level is fine so long as they are DIP chips and not surface mount, my eyes aren't what they used to be.

Thank you!

Yes, of course I am looking for solutions myself too, but I like to ask sailors because, who knows, maybe some smart sailor out there has been there done that and they have some magic box that costs 5$us that does it. Sailors are a creative bunch and I have found them to be very innovative, sometimes with surprising answers that are out of the norm.
