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.

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 inuence of measurement position accuracy or a current
an actual bow it may differ from a direction.
