GND™ 10 Installation Instructions
This device bridges the connection between Nexus® network
devices and a NMEA 2000® network. When the device is
connected to a computer using the included USB cable, you can
calibrate advanced wind transducers such as the gWind Race™
using the NexusRace™ software, and you can use data from the
transducers with programs such as Expedition® and Adrena.
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the
product box for product warnings and other important
information.
CAUTION
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite
side of the surface.
If you are unfamiliar with NMEA 2000, you should read the
“NMEA 2000 Network Fundamentals” chapter of the Technical
Reference for NMEA 2000 Products. To download this
document, select Manuals on the product page for your device

Mounting Considerations
NOTICE
This device should be mounted in a location that is not exposed
to extreme temperatures or conditions. The temperature range
for this device is listed in the product specifications. Extended
exposure to temperatures exceeding the specified temperature
range, in storage or operating conditions, may cause device
failure. Extreme-temperature-induced damage and related
consequences are not covered by the warranty.
When selecting a mounting location, observe these
considerations.
• To avoid interference with a magnetic compass, the device
should not be installed closer to a compass than the
compass-safe distance value listed in the product
specifications.
• You can use the included screws to mount the device on
your boat. If the included screws are not appropriate for the
mounting surface, suitable hardware must be purchased
separately.

The GND10
The GND10 is a converter form Nexus Network to NMEA2000 (used for Garmin and
other manufacturer). Most of the data is converted both ways from Nexus to NMEA2000
and NMEA2000 to Nexus.
The GND10 is delivered with the default settings where all preferred sources are from
the NMEA2000 to the Nexus Network. If you have an existing Nexus Network with
Nexus transducers, you have to change the preferred sources. Select Tools and
Configure and a list of your Nexus Network components are showed:
To change preferred sources for the GND, double click on the GND N2k gateway in the
list.
As you can see all tick boxes are checked and the GND10 will convert NMEA2000 data
and send it out on the Nexus Network. For the transducers/functions you want the
Nexus Network to provide for, un-check the equivalent box:
Page 4
In the example above, a NX2 Server is used and the Log, Depth, Wind and Compass
will all come from the Nexus transducers. GPS Position and Navigation data will come
from the NMEA2000 network and be send out on the Nexus Network. Log, Depth, Wind
and Compass will be send out on the NMEA2000 network from the GND10.
Note:
If a nWind transducer, a HPC Compass or a nGPS antenna. Is connected, they will
always send out the data on the Nexus Network. If you have a nGPS antenna and want
the position data from the NMEA2000 GPS to be used in the Nexus syste, you have to
physically disconnect the nGPS (the same goes for nWind and HPC Compass)
The WSI-box will also be responsible for Log, Depth and Wind on the Nexus Network
unless these functions are un-checked in the WSI-setup box
This WSI-box will only provide Wind information on the Nexus Network!
Install the NexusRace SW
First you download the driver for the GND10:
Page 5
http://www8.garmin.com/support/download_details.jsp?id=6889
Then you download and install the NexusRace SW:
http://www8.garmin.com/support/download_details.jsp?id=6885#Instruct
Run the NexusRace SW
When you start NexusRace, you have to connect it to the GND10.
Press the Connection icon in the top left corner of the tool bar:
Select the comport the GND10 has created. The comport no is displayed during the
installation but if you did not see that, it is normally the last comport in the list.
Press OK and after a couple of seconds, the green connection LED lights up in the top
right corner.
Now you are connected to the GND10 and you can monitor data and more.

Note 1: If a WSI box is used on the Nexus Side, it will not automatically hand over the responsibility to
send speed out on the Nexus Network to the GND10 unless this categories are disabled in the WSI-box.
Only boat speed and Maximum boat speed will work in the Nexus Network. Trip, Log and average speed
will not work!
Note 2: If a WSI box is used on the Nexus Side, it will not automatically hand over the responsibility to
send depth out on the Nexus Network to the GND10 unless this categories are disabled in the WSI-box.
Only will work in the Nexus Network. Shallow and Deep alarm will not work!
Note 3: If a nGPS Antenna is connected to the Nexus Network, it will not hand over the responsibility for
Position, SOG and COG to the GND10. The nGPS will always send position related data as long as it is
connected. To get position data from the GND10 to the Nexus Network, the nGPS has to be
disconnected from the Nexus Network. If a NMEA0183 Antenna is connected to the Nexus Server, the
data will come from NMEA2000 (via the GND10) if the tick box for Position is checked for the GND10
Note 4: If a HPC Compass is connected to the Nexus Network, it will not hand over the responsibility
Heading. The HPC Compass will always send Heading related data as long as it is connected. To get
Heading data from the GND10 to the Nexus Network, the HPC has to be disconnected from the Nexus
Network. If a 35 or 45 degree Compass is connected to the Nexus Server, the data will come from
NMEA2000 (via the GND10) if the tick box for Heading is checked for the GND10
Note 5: The selection if Water temp should come from NMEA2000 (via the GND10) and be send out on
the Nexus Network is determined by the tick box for Log is checked for the GND10
Note 6: Barometric Pressure is send from the Wireless Wind and WSI box. The wired wind sensor does
not provide this information
Page 7
Note 7: The time is transferred from the NMEA2000 via the GND10 to the Nexus Network. Also the time
zone is send. However, the time zone is always -5h (Olathe time) and right now it cannot be changed.
How to select the direction of data conversion
1. Goto www.garmin.com and the GND10
2. Go to Software and install the drivers and the NexusRace SW
3. Connect the GND10 and connect the USB connector to your PC
4. The GND10 will be installed and you will see what Comport it was assagned
5. Start the NexusRace Software
6. Click on the Connect icon
7. Select the COM-port the USB got assigned (If you do not know, it is normally the last in the list)

If a box is checked, the data will go from NMEA 2000 to Nexus Network. If a box is unchecked, the data
will go from Nexus Network to NMEA2000
