The Lowrance unit has an adjustable baud rate, and I set it to 4800. Yes, I tried all the baud rates, the 4800 seemed to be the best one, all the others were even moreso jibberish. I also tried setting the fishfinder to higher baud rates. Ive messed around with the baud rates a lot and I really don't think that's the problem.Does this mean the data converter is the problem?

I think I found your Error. In then Convert Manual Page 3, Have you configured your converter for RS422 or are all the jumper configured for RS485? Attached is a screen grab of the manual image.Make sure the jumpers are correct.Remove all of the jumpers except the J4 jumper. I think your pictures show the jumpers still in place.Chuck.Check out my Kickstarter Project Memory Panes an expansion RAM Shield for Mega2560's. It adds 1MB of RAM for those projects where 8KB is not enough.
