EXTERNAL DATA OUTPUT
[NMEA2]* 2 connector
“RMC”, “GGA”, “GLL”, “VTG”, “TTM” “TLL”, “RSD”
* 1 G; Over ground, TW; Through the water
* 2 [NMEA1] and [NMEA2] connectors; see page 28.
* 3 AIS input also receives “RMC”, “GGA”, “GLL”, “VTG” and “GNS” sentences.
If the NMEA2 input does not receive these, the sentences from the AIS input are used.
*
4 The system error is displayed from the AIS unit.
• “HDG”, “HDM”, “HDT”, “RMC”, “GGA”, “GLL”, “GNS”, “VTG”, “WPL”, “BWC”, “TTM”, “TLL” and “RSD” are SEN -
TENCES of the NMEA0183.
• If BRG INPUT is set to “GPS”, “RMC” of [NMEA2] connector or COG (Course Over the Ground) of “VTG” a bow it
receives as a direction, even if there is no direction information (compass etc.) in [NMEA1] connector, the screen
display of the North rise etc. is possible.
However, direction accuracy falls when the speed of a ship is set to 2 knots or less, or when exceeding 3 knots
a bow it does not receive as direction data. Moreo, the influence of measurement position accuracy or a current
an actual bow it may differ from a direction.
