13INSTALLATION

The RADAR 3000 will interface with any NAV-AID (GPS or LORAN) and

compass that has the standard NMEA0182 or NMEA0183 output. The inputs

from NAV-AID will be digital data conforming to the NMEA0183 formats to

drive various radar features such as waypoint mode. If more than one data type

is present at the radar inputs (for example; compass and NAV-AID), a system

priority has been established in the radar’s software to respond to the inputs in

driving the features. The assigned priorities are set in this manner:

HEADING: 1. Compass (NMEA0183 “HSC,HDM,HDT,VHW”)

2. NAV-AID (NMEA0183 “RMC,RMA,VTG”)

POSISION: 1. NAV-AID (NMEA0183 “RMC,RMA,GLL,GTD”)

SPEED: 1. NAV-AID (NMEA0183 “RMC,RMA,VTG”)

2. Compass (NMEA0183 “VHW”)

WAYPOINT: 1. NAV-AID (NMEA0183 “RMB,BWC”)

Using the outline of FIG 3-5 as a guide, connect the RADAR 3000 to your

NAV-AID and compass.
