Hi All...

I need to recieve two to three channels of NMEA 0183 and send one channel. I looked around for a level converter chip like a MAX232 but for RS-422, but no luck. Is there an easy circuit or chip to use to convert RS-422 to TTL, ideally with electrical isolation?

Thank you.

Yes, very much like that Bob, thank you! I guess you now know what's coming ;-)

I also ran accross someone who had a line of chips with really good isolation built in. I'll have to find those and post. It was pretty early when I saw them and now I can't remember what company it was :-(
