Connecting GPS/DGPS Sensor or Making
NMEA0183 Data Connections (Option)
When displaying the latitude and longitude of your vessel on the screen, or
using the NAVIGATION mode, you are required to connect the optional
GPS112 or DGPS212 sensor to the RADAR 1800, or input the data of
navigational information in the NMEA0183 format from navigation equipment.
Connecting GPS112 or DGPS212 sensor
When using the GPS112 or DGPS212 sensor, connect the 5-pin antenna
connector attached to the signal cable of the sensor to the “GPS” connector at the
rear panel of the unit.
With this, it is possible to receive the necessary data of navigational
information from the GPS112 or DGPS 212 sensor. It is advisable, however, to
perform initial settings according to your conditions using the GPS SETTING,
DGPS SETTING menu of the unit for more precise navigational information.
Refer to p.91 and p.92 for the information about initial settings for each sensor.
Making NMEA0183 data connections
When receiving navigational data information in the NMEA0183 format
from navigation equipment other than this unit, you are required to make a
connecting cable using the 5-pin connector (model 6-282-5SG-325, CONXALL)
and connect it to the “NMEA” connector at the rear panel of the unit.
Connect the 5-pin connector and the connecting cable as shown in Figure
2-9.

Viewed from solder side of connector body
Only the GPS/DGPS sensors manufactured by JRC
can be connected directly to the GPS connector at
the rear panel. If those other than manufactured by
JRC are connected, the equipment may be damaged.
