Page 4: Introduction
Introduction Thank you for purchasing an Airmar solid-state sensor. The compact housing is waterproof with a single removable cable. The H2183 is actually three sensors in a single unit—a three-axis magnetic compass, a three-axis accelerometer, and a three-axis rate gyro. Data is simultaneously output in digital NMEA 0183 and NMEA 2000 formats. -
Page 5: Safety Instructions
Always wear safety glasses, a dust mask, and ear protection when installing. WARNING: Steel Vehicle/Boat Do not install the sensor within a steel vehicle/boat because it is a ferrous (magnetic) material. Instead, use Airmar’s model GH2183, combination GPS and compass that can be mounted above the vehicle/boat. WARNING: Compass Safe Distance The sensor must be a minimum of 0.3m (1') from other standard and steering... -

Page 7: Choosing The Mounting Location
Choosing the Mounting Location For accurate readings, selecting the best location for the sensor is very important. It can be mounted on either a vertical or a horizontal surface. Choose a location that balances the requirements below. • Mount the sensor as close to the vehicle/boat’s center of gravity as possible. The lower it can be mounted, the more stable it will be, thus giving more accurate compass readings. -

Page 12: Cable Routing & Connecting
Depending on the equipment you will be using, route the sensor cable to an Airmar Converter or Combiner, an NMEA 0183 display, an NMEA 2000 network, a laptop, or other device.

Page 15: Calibrating The Compass
Calibrating the Compass WARNING: The internal compass may need to be calibrated after the sensor is installed for maximum accuracy. Perform the pretest below to determine if calibration is necessary. CAUTION: Boat—The Pretest and AutoCalibration Procedure must be done in calm seas in a 0.8 km (0.5 mile) open area away from other boats and ferrous objects such as structures and aids to navigation. -
Page 16: Maintenance
• Is the sensor mounted near the center of the vehicle/boat’s fore-aft axis? Firmware Revisions Airmar may release updated versions of the sensor’s firmware. Periodically, check Airmar’s website at www.airmar.com to down-load the latest revision, or contact Technical Support for a CD.
