NMEA2000
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: heading is required by the display to correctly overlay the radar over a
chart.
• North Up: For the display to show the radar page with the top of the PPI as north.
For heading sensors that output NMEA 0183 (see “NMEA 0183” on page 25)
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.
