Adaptor NMEA 2000 pentru senzorul de unghi al cârmei GRA™ 10

The Garmin GRA™ 10 adapter is designed to convert analog data from a rudder angle sensor or existing gauge into a digital NMEA 2000 signal. This allows the rudder angle to be displayed accurately on Garmin-compatible devices connected to your NMEA 2000 network.

The GRA™ 10 is an adapter that converts signals from an existing rudder angle sensor or analog gauge into NMEA 2000. The GRF™ 10 is a complete solution that includes the rudder position sensor and integrated NMEA 2000 output, without requiring a pre-existing analog sensor.

The GRA™ 10 adapter has compact dimensions of 24.7 mm (width) x 17.0 mm (height) x 78.6 mm (length).

The GRA™ 10 adapter weighs 365 grams (12.85 oz).

Yes, the GRA™ 10 adapter is waterproof to IEC 60529 IPX7 standards. It can be submerged to a depth of 1 meter for up to 30 minutes. However, it must not be installed in an area where it would be regularly submerged.

The GRA™ 10 adapter operates within a temperature range of -15°C to 70°C (5°F to 158°F).

The GRA™ 10 is compatible with 12 V DC analog gauges or directly with resistive rudder angle sensors of the 0-5 V DC type.

No, the GRA™ 10 displays the rudder angle information for reference on compatible displays, but it does not provide feedback for autopilot systems that require a dedicated sensor.

The GRA™ 10 adapter is compatible with Garmin display devices (chartplotters and marine instruments) connected to your NMEA 2000 network. For a complete list of compatible devices, it is recommended to consult Garmin's website.

Yes, the GRA™ 10 is designed to integrate with an existing NMEA 2000 network. It transmits and receives approved NMEA 2000 PGN data, enabling communication with any device compliant with the NMEA 2000 standard.

You must choose a location within 4.4 meters (173 inches) of the analog gauge or rudder angle sensor to avoid splicing bare wires. The location must also be between the NMEA 2000 backbone and the sensor/gauge. Although the adapter is waterproof, it must not be regularly submerged. It must be installed at least 5 cm (2 inches) away from a magnetic compass to avoid interference.

To connect the GRA™ 10 to an analog gauge, consult your boat or sensor’s user manual to identify the ground, sensor, and power (ignition) connections on the gauge. Typical wiring is:

Blue wire: Sensor (S, G)
White wire: Gauge power (+, +12V, I, IGN)
Black wire: Ground (-, G)
The yellow and red wires are not used in this setup. Do not remove any wires from the back of the gauge.

For a resistive sensor, connect the blue wire of the GRA™ 10 adapter to the sensor terminal (S, G) and the black wire to the sensor ground (-, G). The white, yellow, and red wires are not used in this configuration.

For a generic voltage sensor (0-5 V DC), connect the yellow wire of the GRA™ 10 adapter to the sensor terminal (S, G), the black wire to ground (-, G), and the red wire to the 5 V power supply. The blue and white wires are not used in this configuration.

The GRA™ 10 adapter connects to the NMEA 2000 network via the included T-connector. It must be plugged into the existing NMEA 2000 backbone. If the adapter cannot connect directly, a NMEA 2000 drop cable (not included) up to 6 meters (20 feet) long can be used to link it to the T-connector.

The total length of the GRA™ 10 adapter cable is 4.9 meters (16 feet).

The GRA™ 10 adapter draws a maximum of 1.1 W from the NMEA 2000 bus and has a Load Equivalency Number (LEN) of 2, corresponding to a current draw of 100 mA.

To calibrate the rudder angle, turn on the boat’s power (do not start the engine). On your compatible Garmin display device, go to the NMEA 2000 device list, select the GRA™ 10, then choose Review > Rudder Angle Calibration (for most Garmin chartplotters) or Config > Rudder Angle Calibration (for other Garmin marine devices). Follow the on-screen instructions to calibrate port and starboard rudder angles.

If the rudder angle reading varies with engine speed, the GRA™ 10 adapter might detect an incorrect gauge type. To fix this, go to the GRA™ 10 settings on your Garmin display. Select Review > Gauge Type or Config > Gauge Type and choose between Auto Detect, 1 Coil or 2 Coil to correct the issue.

Yes, you can restore the GRA™ 10 to its factory default settings. To do this, go to the NMEA 2000 device list on your Garmin display, select the GRA™ 10, then choose Review > Generic Config (for most Garmin chartplotters) or Config > Generic Configuration (for other Garmin marine devices), and finally select Yes to confirm the reset. Note that all custom configurations will be lost.
