Garmin gWind wireless wind vane anemometer

The gWind Race wind transducer / vane anemometer provides wind speed and wind angle data. This information is then transmitted to an NMEA 2000 network via the Garmin GND 10 interface.

The gWind Race wind transducer integrates via a proprietary Nexus network. It connects to your boat's NMEA 2000 network through the Garmin GND 10 interface, which is included with the product. The GND 10 acts as a critical bridge, translating sensor data from the Nexus system to the NMEA 2000 network.

The Garmin GND 10 interface is a central component that links devices on the Nexus network (such as the gWind Race sensor) to an NMEA 2000 network. It enables the transfer of wind data from the wind sensor to the NMEA 2000 network and, when connected to a computer, allows advanced calibration of the sensor using the NexusRace™ software and the use of data with third-party navigation programs such as Expedition and Adrena.

The gWind Race, with its Nexus wiring and GND 10 bridge, is geared toward enhanced connection reliability and calibration capabilities, often sought after in regatta applications. In comparison, Garmin's gWind Wireless 2 offers more direct wireless NMEA 2000 integration.

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 locking screw to secure the propeller firmly to the device.

The gWind Race wind sensor can be installed either in an existing mast mount or using the included mounting bracket. If using the included mounting bracket, it must be secured to a horizontal surface at the masthead. If no horizontal surface is available, an appropriate shim must be added to create one.

The gWind Race wind transducer must be installed with the cable pointing toward the bow of the boat, parallel to the centerline. If the unit is not mounted with the cable exactly pointing toward the bow, you will need to configure its orientation to receive accurate wind angle data.

If the sensor is not aligned with the bow of the boat, exactly parallel to the centerline, you must adjust this setting. On the marine instrument (e.g., a GMI 20), go to NMEA 2000 settings, select the device name (GND 10), then choose 'Wind angle offset'. Estimate the angle in degrees clockwise relative to the bow of the boat and select this value.

To connect the GND 10 interface to a computer:

Connect the included USB cable to the device's USB port. Connect the other end of the USB cable to a free USB port on your computer. The LED near the USB port will flash green when the device is correctly connected. This connection enables advanced calibration with NexusRace™ software and data use with third-party programs.

Advanced calibration of the gWind Race wind transducer can be performed using the NexusRace™ software. To do this, the GND 10 interface must be connected to a computer via the included USB cable. Once connected, you can use the NexusRace™ software to customize and refine the transducer's accuracy.

You can adjust the responsiveness of the display to wind direction changes. On the marine instrument, go to the NMEA 2000 settings, select the device name (GND 10), then choose 'Wind angle filter'. You can select 'Disabled' for maximum responsiveness, 'Enabled' to set a value (a higher number increases responsiveness, a lower number decreases it), or 'Auto' for automatic adjustment based on wind conditions.

You can adjust the responsiveness of the wind speed display to changes. On the marine instrument, go to the NMEA 2000 settings, select the device name (GND 10), then choose 'Wind speed filter'. You can select 'Disabled' for maximum responsiveness, 'Enabled' to set a value (a higher number increases responsiveness, a lower number decreases it), or 'Auto' for automatic adjustment based on wind conditions.

The Garmin GND 10 interface has the following dimensions: 170 mm (height) x 90 mm (width) x 50 mm (depth).

The GND 10 interface is designed to operate within a temperature range of -15°C to 70°C (5°F to 158°F). It is important to install the device in a location not exposed to extreme temperatures or conditions, as prolonged exposure outside this range may cause device failure.

The GND 10 interface has an IPX7 ingress protection rating. This means the device can withstand accidental immersion in water up to 1 meter deep for a maximum of 30 minutes.

Yes. To avoid interference with a magnetic compass, the GND 10 interface must not be installed closer to a compass than the 10 cm (3.9 in) safety distance specified in the product datasheet.

Yes, when the GND 10 is connected to a computer via the included USB cable, it allows the use of wind sensor data (such as from the gWind Race) with third-party navigation software like Expedition and Adrena.
