    NMEA0183 XDR HEEL data very intermittent

    Heel data only shows up in Expedition intermittently. 
    System is set up with a B&G H3000 Motion into a Digital Yacht WLN30 mux and then a TP Link router. 
    Heel data looks good in the raw data log:
    $IIXDR,A,-0.0,D,HEEL*4E

    But doesn't show up in Expedition or in the log file. Heel looks good on the B&G display.
    Could this be a parsing issue? Any other ideas?

    Thank you,
    Keith

    Maybe there is another heel source that is clearing it?

    I did have a HLink interface defined in the Instruments setup but was not connected. I deleted it and now have only the one NMEA 0183 AIS input. Set for UDP. Not sure what else could be affecting it.
    Still having the same issue with Heel data not showing up in Expedition. It works well when using the HLink but not the UDP. I do see the IIXDR message in the raw data.

    I would always be using HLink instead of NMEA 0183 for instrument data ...
