Brezžični jadralni paket GNX™ 43

To install the gWind™ Wireless 2 sensor, follow these steps:

Install the supplied battery in the sensor by opening the compartment with a #2 Phillips screwdriver and connecting the battery to the dedicated port.Choose a mounting location on a horizontal surface at the masthead, facing forward on the boat and parallel to the central axis.Use the mounting bracket as a template to mark the pilot hole locations.Drill pilot holes with a 4.5 mm (11/64 in) bit.Attach the mounting bracket to the surface using the included screws.Insert the sensor into the mounting bracket by pushing and sliding it until it stops.Tighten the locking nut by hand clockwise to secure the sensor.Attach the safety clip to the sensor to prevent the locking nut from loosening.If the sensor is not precisely aligned forward on the boat, you can adjust its orientation via the GNX™ Wind instrument to obtain accurate wind angle data.

For optimal performance of the GDT™ 43 transducer, mounting location is critical:

On fin-keel sailboats, mount it more than 25 cm and less than 75 cm ahead of the keel, and less than 10 cm from the centerline.On long-keel sailboats, mount it slightly angled toward the bow.Avoid mounting it near sharp hull edges (bilges) on powerboats.On single-screw vessels, do not mount it in the propeller wash path.On twin-screw vessels, mount it between the propellers if possible.The transducer must be parallel to the boat’s fore-aft axis.Ensure the transducer is accessible from inside the vessel.Avoid locations behind frames, stiffeners, fittings, water intakes or discharges, or anything that could create air bubbles or turbulence.Do not mount it where it could be struck during launching, lifting, or storage.It must be in clean (non-turbulent) water for optimal performance.

Yes, the GNX™ 43 wireless sailing pack is fully compatible with an existing NMEA 2000® network. The GNX™ Wind instrument and the GDT™ 43 transducer (via its adapter) connect directly to the NMEA 2000 network. The NMEA 2000 network provides power to the instrument and transmits data from NMEA 2000 sensors. The included NMEA 2000 cables and connectors allow you to connect devices to your existing network or to set up a basic NMEA 2000 network if required.

The Garmin GNX™ 43 pack is designed to provide essential sailing navigation data. It displays accurate wireless wind data (wind speed and direction) via the gWind™ Wireless 2 sensor. Additionally, through the GDT™ 43 transducer connected to the NMEA 2000 network, it provides depth, boat speed through water, and water temperature information.

The GNX™ Wind instrument is designed for flush mounting. Here are the general steps:

Cut out the flush-mount template (included in the box) and position it at the desired location.Drill a 10 mm (3/8 in) pilot hole if using a rotary tool, or use a 90 mm (3.5 in) hole saw to cut the mounting surface along the template’s dotted line.Adjust the hole size as needed with a file and sandpaper.Verify that the instrument fits correctly and that the mounting holes are aligned.Drill 2.8 mm (7/64 in) pilot holes for the screws. If mounting in fiberglass, use a countersink bit to drill only through the gelcoat layer to avoid cracking.Remove the remaining template.Place the supplied gasket on the back of the unit and apply marine sealant around the gasket to prevent leaks.Connect all necessary cables before placing the instrument in the cutout.Securely fasten the instrument to the mounting surface using the provided screws. Apply anti-seize lubricant to stainless steel screws if mounting in fiberglass.Snap the bezel into place.

To achieve the best performance, the GDT™ 43 transducer must be installed in an area of clean (non-turbulent) water and parallel to the bow-to-stern axis of your vessel. Here are specific considerations:

On fin keel sailboats: The transducer must be installed more than 25 cm and less than 75 cm ahead of the keel, and within 10 cm of the centerline axis.On long-keel sailboats: It must be installed at a slight angle pointing toward the bow, not parallel to the centerline axis.General: Avoid installing it behind planking, struts, fittings, water discharge outlets, or anything that could create air bubbles or turbulent water. Ensure the location allows access to the transducer from inside the vessel.

To install the GDT™ 43 transducer, you will need the following tools:

A drillA 43 mm (1 11/16 in) hole sawFor installations on foam-core fiberglass hulls: a 52 to 55 mm (2 1/16 to 2 3/16 in) hole sawMarine sealantSilicone greaseA cable cutterA metal file (for metal hull installations)Fiberglass cloth and resin (optional for sealing a foam-core fiberglass hull)A 43 mm cylinder, wax, tape, and casting epoxy (optional for sealing a foam-core fiberglass hull)

Installation on a foam-core fiberglass hull requires specific preparation to seal the core and prevent water infiltration. Follow this procedure:

Drill a 3 mm (1/8 in) pilot hole from the inside out through the hull. From the outside, use a 43 mm (1 11/16 in) hole saw to cut only the outer fiberglass skin. From the inside, at the pilot hole location, use a hole saw to cut a 9–12 mm (3/8–1/2 in) larger hole through the inner skin and most of the core, without cutting the outer skin. Remove the cut inner skin and core material. Sand and clean the area. Seal the core using either layers of fiberglass cloth and resin or a casting epoxy with a 43 mm cylinder as a spacer. Once the core is sealed and cured, proceed with transducer installation as described in the general instructions.
