Girouette anémométer Garmin gWind™

The Garmin gWind™ wind transducer / vane anemometer is a wind sensor designed to provide accurate wind speed and angle data to your navigation system. It is a key component of the Garmin ecosystem, requiring system integration.

The gWind™ sensor provides wind speed and wind angle data to your NMEA 2000 network.

No, the gWind™ cannot operate autonomously. It requires the Garmin GND™ 10 interface to transmit its data to your boat’s NMEA 2000 network.

The GND™ 10 interface acts as a key bridge, connecting Nexus network devices, such as the gWind™, to your NMEA 2000 network. This bridge is essential for wind data acquisition and sharing.

Yes, the gWind™ is compatible with NMEA 2000 networks, but it must be connected via the Garmin GND™ 10 interface for its data to be transmitted to the network.

Yes, the GND™ 10 interface provides USB connectivity to a computer, enabling the use of wind sensor data, including from the gWind™, with third-party navigation software such as Expedition and Adrena. This also requires the NexusRace™ software for advanced calibration.

To install the propeller:

Ensure the shaft aligns correctly with the propeller’s slot. The propeller bushing fits only one way onto the shaft.Press the propeller until it is fully seated on the device.Install the set screw to secure the propeller firmly to the device.

The gWind™ wind transducer / vane anemometer must be mounted on a horizontal surface at the masthead. It must be installed facing forward, parallel to the boat’s centerline. If the surface is not horizontal, an appropriate shim must be added.

To mount the bracket:

Use the mounting bracket as a template to mark the pilot hole locations.Drill pilot holes with a 4.5 mm (11/64 in) drill bit.Attach the mounting bracket to the surface using the included screws.

To secure the gWind™:

Loosen the locking nut on the device by turning it counterclockwise until it stops. Place the device into the mounting bracket by pushing it down and sliding it backward until it stops. Secure the device in the bracket by turning the locking nut clockwise until it stops. Attach the safety pin to the device to prevent the locking nut from loosening.

You must use the included ground connector to create the appropriate cable length. The gWind™ mast cable connects to one of the NEXUS ports on the GND™ 10.

To install the Nexus ground connector:

Connect the finished end of the included bulk cable to the masthead wind sensor. Route the stripped end of the cable to the GND™ 10 ground location. Leave adequate slack length, cut the stripped wire end, remove the housing, and strip the individual wires. Disassemble the ground connector and place the pressure screw, clamping ring, gasket, and sleeve onto the cable. Using the screws on the rear of the connector, connect each wire to the appropriate terminal (green, yellow, bare wire, white). Screw the sleeve onto the connector. Slide the gasket into the sleeve and slide the clamping ring over the gasket. Screw the pressure screw into the sleeve to complete the ground connector assembly. Connect the ground connector to one of the NEXUS ports on the GND™ 10.

Before you can configure the wind transducer, it must be connected via a GND™ 10 to an NMEA 2000 network with a Garmin marine instrument (such as a GMI™ 20). Configuration is done via the marine instrument's NMEA 2000 settings by selecting the device name (GND™ 10).

If the sensor is not facing exactly forward on the boat, you must adjust this setting. On the marine instrument, go to NMEA 2000 settings, select the device name (GND™ 10), then choose Wind Angle Offset. Select the angle in degrees to adjust the orientation difference, with the angle configured clockwise around the mast from the exact center of the bow.

To adjust the wind angle filter:

On the marine instrument, go to the NMEA 2000 settings, select the device name (GND™ 10). Select Wind Angle Filter. Choose an option: Disabled for maximum responsiveness. Enabled and adjust the value (a higher number increases responsiveness, a lower number decreases it). Auto for automatic adjustment based on wind conditions. Select Done.

To adjust the wind speed filter:

On the marine instrument, go to NMEA 2000 settings, select the device name (GND™ 10). Select Wind Speed Filter. Choose an option: Disabled for maximum responsiveness. Enabled and adjust the value (a higher number increases responsiveness, a lower number decreases it). Auto for automatic adjustment based on wind conditions. Select Done.

If you switch from a Nexus wind sensor to a gWind™, you must move the mast cable from the wind port to the network port on the Nexus server (pins 5, 6, 7, and 8). The network server is NX2 and the classic server is BUS. Refer to the Nexus device manual for further details.

Yes, you must connect a Nexus network device to one of the NEXUS ports of the GND™ 10. However, if you connect additional devices in addition to the gWind™ sensor on the Nexus network, you must provide a separate power supply connected directly to the Nexus power terminals.

If necessary, use a mild soapy solution to clean the wind transducer / vane anemometer, then rinse it with water. Do not use detergents or high-pressure water.

The GND™ 10 interface must be installed in a location not exposed to extreme temperatures or conditions. The operating temperature range for this device is -15°C to 70°C. Prolonged exposure to temperatures outside this range, whether in storage or operation, may result in device failure. Damage caused by extreme temperatures and related consequences are not covered by the warranty.
