pass depth info in dashboard ?

[abarrow]

I was getting nmea data out of my ST60 and it wasn't showing on OpenCPN, even though I could see it on the port. I think it had something to do with the data not having a checksum, so I took it into Node-Red and added a checksum. While I was at it I did a calculation on the data and rebuilt the string so that it included all values (meters, feet and fathoms). It fixed the problem. There's a thread here somewhere where it was discussed, and the Node-Red script exchanged.

It became unnecessary after I got the Quark-Elec SeaTalk converter, but the code that I used is around here somewhere!
