External data output
The radar can output the following sentences through the [NMEA 2] * 1 connector: RMC, GGA, GLL, VTG, TLL,
RSD, and OSD.
*1 [NMEA1] and [NMEA 2] connectors: See the page 44.
*2 AIS input also receives RMC, GGA, GLL, VTG, and GNS sentences.
These are valid only when the NMEA2 input and DSC input do not receive them.
*3 Either an HDG to [NMEA 1] connector or an RMC to [NMEA 2] connector is required.
L
THS, HDG, HDM, HDT, RMC, GGA, GLL, GNS, VTG, WPL, BWC, BWR, TTM, TLL, RSD, OSD, DSC, and DSE are the
sentence formats of NMEA0183.
L
If the “Bearing Input” item in the Initial menu is set to “GPS” or “GPS-L,” “RMC” of [NMEA 2] 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
[NMEA 1] 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 influence of measurement position accuracy or a current an actual bow
it may differ from a direction.
*4 A system error from the AIS unit is displayed.
