Viewing Sensor Information

The instrument shows sensor information using up to four instrument screens. You can customize the number of instrument screens (Adjusting the Number of Instrument  Screens, page 3), and you can customize the data shown on each instrument screen (Customizing an Instrument Screen, page 3).

1. When MENU or SUBMENU is shown, press repeatedly until you view an instrument screen.
2. Press and to move through the available instrument screens.

Wind Rose
The wind rose shows a visual representation of the wind angle or direction provided by the connected wind sensor. You can configure the wind rose to show three types of  wind information on an instrument screen:

• Both the true wind angle and apparent wind angle at the same time
• A focused view for close-hauled sailing
• The true wind direction

True and Apparent Wind Rose
When the center of the wind rose is empty, the wind rose shows both true and apparent wind angles using two types of needles.

1. Shaded needle: the apparent wind angle (AWA)
2. Single needle: the true wind angle (TWA)

Close-Hauled Wind Rose
When CH appears in the center of the wind rose, the wind rose shows both the true and apparent wind angles in a focused section for close-hauled sailing.

1. CH: the wind rose is focused on close-hauled (CH) sailing.
2. Shaded needle: the apparent wind angle (AWA)
3. Single needle: the true wind angle (TWA)
4. The wind rose scale: the scope of the focused area, which adjusts automatically based on the direction of the boat.

Wind Direction Wind Rose
When TWD appears in the center of the wind rose, the wind rose shows the true wind direction using two types of needles. The needles indicate the true wind direction based on relative north. You should disregard the boat symbol on the wind rose in this mode.

1. True wind direction (TWD): the wind rose is showing the true wind direction.
2. Single needle: the direction the wind is coming from.
3. Double-needle: the direction the wind is heading to.

Steer-Pilot Mode

You can use the marine instrument to help you steer using a specific wind angle or information received from connected sensors and a GPS device.
You can also use the marine instrument to help when tacking.

Configuration Menus

This section provides details for the items in the configuration menu, organized by menu and sub-menu decimal values.
DATA Configuration Settings

1. Lower data field configuration: Changes the speed type on the current instrument page.
2. Upper data field configuration: Changes the wind direction or angle type on the current instrument page.
3. The wind rose configuration: Changes the function of the wind rose on the current instrument page.

FILT Configuration Settings
In the filter configuration menu, you can adjust the damping of the data received from the sensor before it is shown in each data category (2.1 through 2.9).
The higher you set the update rate (0 through 9) for each data category, the more the data is dampened to remove the more extreme readings. For example, setting a higher filter for  TWS may provide a more stable wind-speed reading in gusty conditions.
The glossary defines the data-type abbreviations used in this menu (Abbreviation Glossary, page 4).

UNIT Configuration Settings

1. WIND: Changes the units of measure used for wind speed.
2. BSP: Changes the units of measure used for boat speed.
3. NORTH: Changes the north reference for the heading and wind direction. MAG stands for magnetic north, TRU stands for true north, and GRD stands for grid.

SENS Configuration Settings

1. WIND: Turns data from the connected wireless wind sensor on or off. When off, data from the connected wireless wind sensor is not transmitted over the NMEA 2000  network.
2. ANGL: Adjusts the angle of the wind sensor to align with the front of the boat.
3. RSSI: This shows the signal strength between the instrument and the wireless wind sensor.
4. BSP%: Adjusts the calibration of boat speed information shown on the instrument.
   NOTE: This adjustment affects the information as shown on the marine instrument only. Other devices using speed information from the NMEA 2000 network must be calibrated separately if needed.

3. BEEP: Tuns the key-press sounds on or off.

4. POWR: This allows you to change how the instrument turns on.The Aug option turns the instrument on automatically when
   the NMEA 2000 network turns on.
   The OFF option keeps the instrument off when the NMEA 2000 network turns on. The instrument must be turned on by pressing.

5. PAGES: Sets the number of instrument pages.

6. SCRL: Sets and adjusts your instrument screens to scroll automatically. The value you set (0 through 9) represents the number of seconds between each screen change.
