I have Raymarine
ST60 instruments and I wanted to be able to see their data at the nav table. My first instinct was to get a repeater, but the sticker shock drove me straight to the internet
in search for an affordable alternative.
Through some forum--maybe this one, I'm not sure--I learned about YAPP Electronics
. John builds a very affordable SeaTalk
interface box that connects to a computer through USB. He's quick to respond to questions, even though he builds this device in his spare time.
Once you have the data on USB, the sky's the limit. I use OpenCPN
and various iOS and Android apps to see the data from the Raymarine
Do you have your computer connected to your instruments? If so, what do you use to look at the data?
