AIS input also receives “RMC,” “GGA,” “GLL,” “VTG,” and “GNS” sentences.
If the NMEA2 input or DSC input does not receive these, the sentences from the AIS input are used.

The system error is displayed from the AIS unit.

Either an “HDG” to [NMEA1] connector or an “RMC” to [NMEA2] connector is required.
• “THS,” “HDG,” “HDM,” “HDT,” “RMC,” “GGA,” “GLL,” “GNS,” “VTG,” “WPL,” “BWC,” “BWR,” “TTM,” “TLL,”
“RSD,” “OSD,” “DSC,” and “DSE” are sentences of NMEA0183.
• If the “Bearing Input” item in the Initial menu is set to “GPS” or “GPS-L,” “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 vessel is set to 2 knots or less, or when exceeding 3
knots a bow it does not receive as direction data. Moreover, the inuence of measurement position accuracy or
a current an actual bow it may differ from a direction.
