Configuring the Data Fields

Data provided on an instrument page can be shown in various

ways depending upon the instrument page that is displayed.

Select > CONFIGURE DATA FIELDS.

Select a data field.

Select a configuration option.

Filtering the Data

Certain data types can be filtered to control how quickly the

marine instrument responds to changes in the data (Data Type

Information, page 5).

When viewing data you need to filter, select >

CONFIGURE DATA FIELDS.

Select a data field.

Select FILTER SETTING.

Adjust the filter setting.

• Setting the filter to "0" turns off filtering.

• The higher the filter setting, the more gradually the

instrument displays changes in the data it receives.

For example, when you increase the filter setting for wind

speed data, the instrument is less responsive to

momentary gusts of wind and displays a more constant

wind speed.

Adjusting the Data Update Rate

You can adjust the rate at which the marine instrument shows

updated data.

When viewing the instrument screen with data you need to

adjust, select > CONFIGURE DATA FIELDS.

Select a data field.

Select UPDATE RATE.

Select an update rate.

Examples of update-rate speeds are shown next to each

selection.

Configuring Graph Data Fields

Some single-function instrument pages display graph data (Data

Type Information, page 5). You can configure how data is

shown on the graphs.

From an instrument page with a graph, select >

CONFIGURE DATA FIELDS > GRAPH SETTINGS.

NOTE: The GRAPH SETTINGS menu item does not appear

on instrument pages that do not contain a graph.

Select an option:

• To determine how long the graph data displays, select

GRAPH DURATION.

• To configure the scale of values displayed in the graph,

select GRAPH SCALE.

Configuring Gauge Data Fields

Some data types can be shown as a gauge when they appear

as the last function on a two-function instrument page (Data

Type Information, page 5). You can configure how data is

shown on the gauge.

From an instrument page with a graph, select >

CONFIGURE DATA FIELDS > GAUGE SETTINGS.

NOTE: The GAUGE SETTINGS menu item does not appear

on instrument pages that do not contain a gauge.

Select a value to adjust the limits of the gauge.

Using the Race Timer

To view the race timer on a page, you must add it as a data field

from the SAILING category.

You can use the race timer to count down to a race, and then

measure the duration of the race. The race timer is

synchronized with other GNX instruments and compatible

Garmin

chartplotters on the same NMEA 2000 network.

TIP: To quickly open the race timer screen, you can hold

from a main page. This shortcut works from any page, whether

or not the race timer has been added to the page.

From a page with the race timer as a data field, select >

CONFIGURE DATA FIELDS > RACE TIMER SETTINGS.

Select an option:

• When the device is in prerace mode and the timer is not

running, select START to start the prerace timer, select

RESET to reset the prerace timer, or select SETUP to

adjust the initial prerace timer value.

• When the prerace timer is running (counting down), select

or to advance the timer to the next minute up or the

next minute down, or select STOP to stop the prerace

timer.

• When the race timer is running (counting up), select STOP

to stop the race timer, or select to reset the timer back

to 0:00.
