Icom MR-1000TTM - Manual (Page 43)

The following external bearing, speed, position and way point data is (are) required , when you use the radar func-
tions.
* 1 OG; Over ground, TW; Through the water
* 2 NMEA1 and NMEA2 connectors; See p. 24
• “HDT”, “HDM”, “RMC”, “GGA”, “GLL”, “VTG”, “WPL”, “GNS” and “BWC” are SENTENCES 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 or less kts, or when exceeding 3 kts 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.
