NMEA 2000
The RI-12 can be connected to a Micro-C NMEA 2000 network to receive heading and position
information.
A heading sensor is required for the following functionality;
• MARPA : heading at 10 Hz or faster is required for the radar to calculate MARPA tracking. Heading
must also be connected to the display.
• Radar Chart overlay and North-up: Heading is required by the multi-function display
For heading sensors that output NMEA 0183 (see “NMEA 0183” on page 30)
For magnetic heading sensors, heading calibration should be performed before using MARPA
or Chart Overlay, and repeated annually, and after any major structural changes to the vessel.
