Appendix A – Connecting Peripheral Instruments

Connecting Directly to Radar

In order for Navigator to be able to display range rings, cursor infor- mation, and electronic bearing lines, the radar system you use must be able to output the NMEA RSD string.

To display MARPA targets, your radar must be able to output NMEA TLL or TTM strings. If you are going to this feature, make sure your radar system is correctly tracking the MARPA targets before connect- ing it to Navigator.

To connect directly to radar, refer to Figure A-1 and Table A-3.
