10kW and 25kW Installation Manual
Connect the NMEA/Comms cable (Heading)
A heading sensor is required for the following functionality;
•
MARPA : heading at 10hz or faster is required for the radar processor. 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.
The radar processor input (labeled NMEA / COMMS) is compatible with a NMEA 0183 heading
sensor.
For heading sensors that output NMEA 2000 PGNs or SimNet, an AT10HD must be used to
convert PGNS to NMEA0183 @ 4800 baud
Heading calibration should be performed during initial setup, annually, and after any major
structural changes to the vessel.

Note:
the Micro-C backbone requires 12 V DC, and should therefore not be connected di-
rectly to the radar pocessor power supply which is 24 V DC.
Confi guration on display
Final setup steps such as bearing alignment, and scanner height need to be done on the
display MFD. Refer to the display installation manual for further details.
