Navigation Data
Navigation data can be displayed on the screen if this radar receives navigation input from a
Loran-C, NNSS (satellite navigator) or GPS navigator whose output format is NMEA 0183
or FURUNO CIF. Data displayable include own ship's position in latitude and longitude (or
Loran-C time differences (TDs)), bearing and range to a waypoint selected on the nav aid,
own ship's speed, heading and course. In addition, if a heading sensor or gyrocompass is also
connected, a line connects a waypoint (selected on navaid), denoted by a dashed ring, with
the own ship's position.
To turn the navigation data display on or off, press the
MENU
touchpad and select "8. NAV
DATA". Refer to table 2-1 on page 2-9.
To display TDs instead of L/L, press the
GAIN

If the output format is FURUNO CIF a jumper wire must be connected to VUPl" on the SPU
Board in the displt^ unit. (See the note below. For the location of JUPl, see Figure 5~2.) Note
that for CIF format the bearing measurement method (Magnetic or True) does not appear for
bearing to waypoint data.
