Depth In (Selecting Depth Data Input); Course In (Selecting Course Data Input); Position In (Selecting Position Input) - JRC RADAR 1800 Instruction Manual

DEPTH IN (Selecting depth data input)

• In this menu, you can select the depth data input from the external
NMEA source or OFF. When NMEA is selected, the depth data input
from the external depth gauge is displayed.
Note:
• When you input the depth data from an external water temperature
gauge, you need to connect the specified signal line to the NMEA
connector on the rear panel. In addition, be sure to check that the
NMEA0183 sentences of $xxDPT or $xxDBT are output from the
connected water depth gauge. (You can check this easily using the self test
mode of the RADAR 1800.)

COURSE IN (Selecting course data input)

• In this menu, you can select the vessel's course data input from GPS,
GPS compass, or magnetic compass. When GPS is selected, the
course data is inputted from GPS.
Notes:
• When you select input source to GPS and you use an external NMEA
source (select NMEA at POSITION IN menu), you need to connect the
specified signal line to the NMEA connector on the rear panel. In
addition, be sure to check that the NMEA0183 sentences of $xxHDT,
$xxHDG, $xxRMC, or $xxVTG are output from the connected GPS.
(You can check this using the self test mode.)
• When you select input source to GPS COMPASS, you need to connect the
specified signal line to the DC12V/COMPASS connector on the rear
panel. In addition, be sure to check that the NMEA0183 sentences of
$xxHDT is output from the connected GPS compass. (You cannot check
this using the self test mode.)
• When you select input source to MAG, you need to connect the specified
signal line to the DC12V/COMPASS connector on the rear panel. In
addition, be sure to check that the NMEA0183 sentences of $xxHDT,
$xxHDG, $xxHDM, or $xxVHW are output from the magnetic compass.
(You cannot check this using the self test mode.)

POSITION IN (Selecting position input)

• In this menu, you can set the source of the navigation information
data such as position, course, geodetic information, etc. The RADAR
1800 provides the GPS/DGPS connector which allows a direct
connection of the DGPS212 or GPS112, and the NMEA connector
to input the NMEA0183 formatted navigational information data
from the external navigation aids. The navigational information input
from the connector selected in this item is displayed on the screen.
When GPS is selected, the navigational information input from the
GPS112 or DGPS212 connected to the GPS/DGPS connector on the
rear panel is displayed. When NMEA is selected, the navigational
information input from the external navigation aids is displayed.
