Auto Guidance maintains a wide clearance from obstacles in open water, even if you set the Shoreline Distance setting to Near or Nearest. As a result, the chartplotter may not reposition the Auto Guidance line, unless the destination selected requires navigation through a narrow waterway. 10Repeat steps 3 through 9 at least once more, using a different destination each time, until you are familiar with the functionality of the Shoreline Distance setting. Communications Settings NMEA 0183 Settings Select Settings > Communications > NMEA 0183 Setup. Port Types: See Setting the Communication Format for Each NMEA 0183 Port, page 41. Output Sentences: See Configuring NMEA 0183 Output Sentences, page 41. Position Precision: Adjusts the number of digits to the right of the decimal point for transmission of NMEA output. XTE Precision: Adjusts the number of digits to the right of the decimal point for NMEA crosstalk error output. Waypoint IDs: Sets the device to transmit waypoint names or numbers via NMEA 0183 while navigating. Using numbers may resolve compatibility issues with older NMEA 0183 autopilots. Defaults: Restores the NMEA 0183 settings to the original factory defaults. Diagnostics: Displays NMEA 0183 diagnostic information. Configuring NMEA 0183 Output Sentences You can enable and disable NMEA 0183 output sentences. 1 Select Settings > Communications > NMEA 0183 Setup > Output Sentences. 2 Select an option. 3 Select one or more NMEA 0183 output sentences, and select Back. 4 Repeat steps 2 and 3 to enable or disable additional output sentences. Setting the Communication Format for Each NMEA 0183 Port You can configure the communication format for each internal NMEA 0183 port when connecting your chartplotter to external NMEA 0183 devices, a computer, or other Garmin devices. 1 Select Settings > Communications > NMEA 0183 Setup > Port Types. 2 Select an input or output port. 3 Select a format: • To support the input or output of standard NMEA 0183 data, DSC, and sonar NMEA input support for the DPT, MTW, and VHW sentences, select NMEA Std.. • To support the input or output of standard NMEA 0183 data for most AIS receivers, select NMEA High Speed. • To support the input or output of Garmin proprietary data for interfacing with Garmin software, select Garmin. 4 Repeat steps 2-3 to configure additional input or output ports. NMEA 2000 Settings Select Settings > Communications > NMEA 2000 Setup. Device List: Displays the devices connected to the network. Label Devices: Changes the labels for available connected devices. Garmin Marine Network The Garmin Marine Network allows you to share data from Garmin peripheral devices with the chartplotters quickly and easily. You can connect a chartplotter to a Garmin Marine Network to receive data from and share data with other Garmin Marine Network-compatible devices and chartplotters. Setting Alarms Navigation Alarms Select Settings > Alarms > Navigation. Arrival: Sets an alarm to sound when you are within a specified distance or time from a turn or a destination. Anchor Drag: Sets an alarm to sound when you exceed a specified drift distance while anchored. Off Course: Sets an alarm to sound when you are off course by a specified distance. Setting the Anchor Drag Alarm You can set an alarm to sound if you have moved more than an allowable distance. This is very useful when anchoring overnight. 1 Select Settings > Alarms > Navigation > Anchor Drag. 2 Select Alarm to turn on the alarm. 3 Select Set Radius, and select a distance on the chart. 4 Select Back. System Alarms Alarm Clock: Sets an alarm clock. Unit Voltage: Sets an alarm to sound when the battery reaches a specified low voltage. GPS Accuracy: Sets an alarm to sound when the GPS location accuracy falls outside the user-defined value. Sonar Alarm Settings NOTE: Some settings require external accessories. Select Settings > Alarms > Sonar. Shallow Water: Sets an alarm to sound when the depth is less than the specified value. Deep Water: Sets an alarm to sound when the depth is greater than the specified value. Water Temp.: Sets an alarm to sound when the transducer reports a temperature that is 2°F (1.1°C) above or below the specified temperature. Contour: Sets an alarm to sound when the transducer detects a suspended target within the specified depth from the surface of the water and from the bottom. Fish: Sets an alarm to sound when the device detects a suspended target. • sets the alarm to sound when fish of all sizes are detected. • sets the alarm to sound only when medium or large fish are detected. • sets the alarm to sound only when large fish are detected. Setting Weather Alarms Before you can set weather alarms, you must have a compatible chartplotter connected to a weather device, such as a GXM device, and have a valid weather subscription. 1 Select Settings > Alarms > Weather. 2 Turn on alarms for specific weather events. Setting the Fuel Alarm Before you can set a fuel level alarm, a compatible fuel flow sensor must be connected to the chartplotter. Device Configuration 41
