Position and Heading, but Not Depth . . .

[dave777]

I'm getting lat & long position as well as speed and heading displayed from NMEA input from plotter system Raymarine. However, I'm not getting things like Depth and Rudder Angle even though they display on the boat's electronics.

Any ideas?

dave...
Which plotter? Wired through a multiplexer/SeaTalk->NMEA converter or to the NMEA output of the plotter? If so, is the plotter actually sending the NMEA sentences out?
This subject can be pretty tricky and your info is scarce...
The first thing to check is the NMEA stream the computer is actually getting (the source being whatever).

It's the NMEA output of the RL80CRC+ plotter. On the plotter's NMEA out config page, every datum is set to transmit. I am getting some data, just not others. I'm running OpenCPN on a laptop.

I know the 10 sec button press to watch NMEA or SeaTalk receipt and transmission on the RL80 so my next step is to find the code for the depth sentence, see if it is received, then see if it is transmitted. Could be the software on the PC, the ST60 sending, or the RL80 forwarding.
