Wind Data is Not the Same Between Multiple Garmin Devices or Instruments

• • The Wind Angle Filtering feature averages the readings and removes big jumps or peaks between reported wind angle shifts. It can be beneficial when using the Autopilot in Wind Hold

  • Changing the Wind Angle Filter setting value affects every device transmitting and receiving the NMEA 2000 PGN 130306--Wind Data

    • Affected devices: Garmin chartplotters, GND™ 10 sailing device | Reactor™ 40 autopilot| GHC™ 20 autopilot controller| GMI™ 20 marine instrument | GNT™ 10 , and all GNX™ IFR Navigator 

    • Third-party devices on the vessel may also be affected

  • Users can only enter the desired Wind Angle Filter setting value from a GMI 20™ marine instrument | GHC 20 autopilot controller, or a chartplotter on the same NMEA 2000 as a GND 10 black box bridge

    • The actual Wind Filter data value is set and processed in the GND 10 black box bridge, then sent via NMEA 2000 to other devices on the network

    • GNX devices can not change the GND 10 Filter values, it can only receive the data and add an additional layer of filtering locally

NOTE: The term "Localized or Locally" refers to the effect of the settings applied to the specific device. The settings do not send across the NMEA 2000 network to other devices.  

• • See  Data Filter Settings on Garmin Marine Instrumentation and Devices

• • Visually inspect and verify that the gWind™ transducer is moving freely and is responding (pointing correctly toward the wind) 

  • Ensure the GND, GNX, GMI , or chartplotter is on the NMEA 2000 Network

    • From the chartplotter follow this path: Options > Settings > Communications > NMEA 2000 Set Up > Device List > Look for the GMI 20, GNX series devices, GND 10 and chartplotter on the vessel

    • Ensure physical connection to the NMEA 2000 Network if a device is missing from the list

  • Identify if the GND 10 NMEA 2000 and NEXUS status light color and if it is solid or flashing. See GND 10 Owners/Installation Manual for "Status LEDs" code 

    • See GND 10 Status or Blink Codes for more information

  • If the vessel has a gWind™ Wireless 2 transducer, ensure the wireless connection to the device is enabled

    • If the gWind™ Wireless 2 transducer connects to GPSMAP and a GNX WIND simultaneously. Disconnect the wireless signal from one of the devices

    • Wirelessly connecting to a GPSMAP and GNX Wind Marine Instrument simultaneously may result in inaccurate wind information displayed between the GPSMAP and GNX WIND

1. 1. Ensure the "Basic Troubleshooting" is completed

   2. Ensure the type of data displayed is the same on the other devices 

      • • Identify, select and confirm that the same type of wind data is displayed on two or more devices

        • Confirm wind information is the same on multiple devices

        • If the data type is the same, but the information being displayed is different between multiple devices, the "Filter Setting or Refresh Rate" may have been set up to show two different values between the instruments

   3.  Based on the type of devices and instruments installed, follow one of the paths below to establish "Filter Settings and Refresh Rates" and check the results

• • • Identify what combination of devices and instruments are installed on the vessel

    • Follow the steps below to document, establish new settings, and observe the data

1. 1. 1. 1. Document what the current differences are in information displayed and the current settings; so a comparison can be accomplished if needed

         2. If the vessel does not have a chartplotter, GHC or GMI 20, skip steps 3 and 4

         3. Establish the GND 10 Filter Settings across the NMEA 2000 Network 

            • From the chartplotter go to: Options > Settings > Communications > NMEA 2000 Set Up > Device List > GND 10 > Review

            • If the vessel does not have a chartplotter, access the settings through the GHC or GMI 20

            • From the GHC or GMI 20 go to: Menu > Set-up > NMEA 2000 Set-up > Device List > GND 10 > Config > Wind Angle Filter > Change Filter > Set the numeric value to "01"

            • Select Angle Filter > Change Sensitivity > enter "01" press Done

            • The GND 10 Wind Filter is now set to "01" and communicates across the NMEA 2000 Network to the other devices and instruments

            • When accessing the GND 10 Wind Angle Filter settings via a chartplotter, the GMI 20 and GHC will automatically update & receive the new Filter Setting value from the GND 10. No action is required on the GMI 20 or GHC  

            • If the vessel has a GPSMAP installed and the software version is at or above 26.10  (Skip step 4)

         4. If the GPSMAP Operational software is below 25.30 the "Preference > Filter Settings" page is not available 

            • Ensure the GPSMAP Filter Settings are "localized" to the GPSMAP.  Follow this path:

              • Follow this path: Options > Settings > Preferences > Filter Settings > Select the specific Wind filter not providing the same displayed information between multiple devices. Decrease the filter to "0"

            • On the "Filter Settings" page, ensure "Sync Filters is "OFF"

            • Return to Home screen and populate the display with the Wind Data Type that was not the same as the other devices displayed  

              • If the vessel has a GNX 20 / 21 / 120 / 130 installed, refer to step 5

              • If the vessel has a GNX Wind Marine Instrument installed, refer to step 6

         5. If the vessel has a GNX 20 / 21 / 120 / 130 installed, establish a localized filter setting for that device

            • From the GNX Home page: Set up > Data Sources > Wind > 210017328 > Angle Filter > On  Enter "01"

            • Return to the Home screen with the same wind data type as the chartplotter is displaying

            • If the vessel does not have a GNX Wind Marine Instrument installed, skip step 6

         6. If the vessel has a GNX Wind Marine Instrument installed, establish a localized setting for that device

            • From the Home screen: Menu button > Arrow down button > 2.0 FILT > Menu button  cycle through the different Wind Data types  and select wind data that needs to be filtered - Set the Filter to "0"

            • The wind data type selected in the GNX Wind Marine Instrument is now set to "0"

            • Return to the Home screen

         7. Compare the information on the chartplotter to the GMI or GNX instrument

            • The information should be close to the same value, scale, angle, or speed

              • Vessels may experience lag time between devices due to the number of devices, size and length of the NMEA 2000 network

         8.  Users can now change the GND 10 filter settings to effect the entire NMEA 2000 network or change the settings locally at the GPSMAP or GNX Series instruments

NOTE:  The  gWind™ Wireless 2 transducer will only wirelessly connect to either a GNX Wind Marine Instrument or a GPSMAP Chartplotter. ECHOMAP Chartplotters, GMI 20,  GNX 20, GNX 21, GNX 120, and GNX 130 instruments can not wirelessly connect to a gWind™ Wireless 2 transducer communicate via the NMEA 2000 network.
