NMEA 2000 Checklist Intelliducer (Intelligent Depth Transducer-Transom Mount and Thru-Hull) Setting the Keel Offset Adjust the Keel Offset to display a depth reading from the water line or from the lowest point of the boat (keel) rather than the actual location of the Intelliducer. To adjust the keel offset: 1. While viewing the NMEA 2000 device configuration menu, select a specific Intelliducer and select Config > Keel Offset. 2. Enter the measured distance from the Intelliducer location to the water line or to the keel of the boat. • If you are measuring down to the keel (Intelliducer installed at the water line), enter a (+) positive number. • If you are measuring up to the water line (Intelliducer installed on the keel), enter a (-) negative number. Intelliducer at the water line Enter a (+) positive number to show depth at the bottom of the keel. Intelliducer at the bottom of the keel Enter a (-) negative number to show depth at the surface. Keel Offset GWS 10 (Garmin Wind Sensor) Configuring the Wind Angle Offset (Orientation) When mounting the sensor, you must adjust the angle offset if you did not orient the GWS 10 as described in the GWS 10 Installation Instructions. To configure the wind angle offset (orientation): 1. While viewing the NMEA 2000 device information, select Config > Wind Angle Offset. 2. Select the angle in degrees to adjust for the difference in orientation. Tip: The angles are configured clockwise around the mast of the boat. For example, 90 degrees is on the starboard side of the boat, and 270 degrees is on the port side. Configuring the Wind Speed Filter The wind speed filter governs how quickly the NMEA 2000-compatible display device shows a change in the wind speed. A lower filter setting shows changes in the wind speed more gradually, and may stabilize the display. To configure the wind speed filter: 1. While viewing the NMEA 2000 device information, select Config > Wind Speed Filter. 2. Choose from the following options to adjust the filter settings. • Off-the wind speed data is not filtered. • On-select a lower number to show a change in the wind speed more gradually, and help the gauge needle or wind speed number to move or change more steadily. • Auto-automatically adjusts the filter settings based on wind conditions. 36 Technical Reference for Garmin NMEA 2000 Products
