[CA] [CA11] Ground log on NMEA output

[Chuck - Raymarine - Moderator]

Tim,

The format for the VLW sentence follows:

$xxVLW,DATA_TOTAL_WATER_DISTANCE_NM,N,DATA_TRIP_WATER_DISTANCE_NM,N,DATA_TOTAL_G​ROUND_DISTANCE_NM,N,DATA_TRIP_GROUND_DISTANCE_NM,N*hh<0D><0A>

The values reported are indeed as stated within my initial response. Fields which are not populated will be left blank. On my own system running LHII v19.03, the VLW sentence is not populating the ground log and ground trip distances. The transmitted sentences appear as follows:
$VWVLW,0.0,N,0.0,N,,,,*7C .... note the comma delimited fields are not populated for the ground data values.
