Mounting the GSI 10 Black Box Device
NOTICE
If you are mounting the device in fiberglass, when drilling the pilot holes, use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
NOTE: Screws are included with the device, but they may not be suitable for the mounting surface.
Before you mount the device, you must select a mounting location, and determine what screws and other
mounting hardware are needed for the surface.
1Place the black box device in the mounting location, and mark the location of the pilot holes.
2Drill a pilot hole for one corner of the device.
3Loosely fasten the device to the mounting surface with one corner, and examine the other three pilot-hole
marks.
4Mark new pilot-hole locations if necessary, and remove the device from the mounting surface.
5Drill the remaining pilot holes.
6Secure the device to the mounting location.
Connection Considerations
When connecting this device to power and to other Garmin devices, you should observe these considerations.
• The power and ground connections to the battery must be checked to make sure they are secured and
cannot become loose.
• The cables may be packaged without the locking rings installed. The cables should be routed before the
locking rings are installed.
• After installing a locking ring on a cable, you should make sure the ring is securely connected and the o-ring
is in place so the power or data connection remains secure.

Garmin Marine Network Considerations
NOTICE
You must not connect any third-party device, such as a FLIR® camera, to a NETWORK port on this device.
Connecting an unapproved device may damage the Garmin device, may damage the third-party device, and will
cause abnormal behavior on the Garmin devices, including inoperable software.
This device can connect to approved Garmin Marine Network devices to provide specific data to a computer
or third-party system using the Garmin Marine Sensor Interface API. When connecting approved Garmin Marine
Network devices to this device, observe these considerations.
• All devices connected to the Garmin Marine Network must be connected to the same ground. If multiple
power sources are used for Garmin Marine Network devices, you must tie all ground connections from all
power supplies together using a low resistance connection or tie them to a common ground bus bar, if
available.
• A Garmin Marine Network cable must be used for all Garmin Marine Network connections.
◦Third-party CAT5e or CAT6 Ethernet cable and RJ45 connectors must not be used for Garmin Marine
Network connections.
◦Additional Garmin Marine Network cables and connectors are available from your Garmin dealer.
• The NETWORK ports on the device each act as a network switch. Any approved device can be connected to
any NETWORK port to share data.
• You must not connect your computer or third party device to this device using a NETWORK port. You must
connect your system or computer using the included Ethernet cable adapter.
Installing Ferrite Beads on the Cables
To comply with regulations and to reduce electromagnetic interference (EMI) or "noise", you must install ferrite
beads on the power cable and the Garmin Marine Network cables.
• You must install one ferrite bead on the power cable, near the connector.
• You must install two ferrite beads on each Garmin Marine Network cable in use, one near each connector.
Five ferrite beads are included. If your installation uses more than two Garmin Marine Network cables, you must
purchase additional ferrite beads from your Garmin dealer to install on the additional cables.
1Make a small loop in the power cable or Garmin
Marine Network cable near the connector to create
a doubled section of the cable.
The doubled section of the cable helps to hold the
bead in place without sliding.
2Place the doubled area of the cable inside the open
ferrite bead.
3Securely snap the ferrite bead closed.
4For a Garmin Marine Network cable, repeat steps 1
through 3 on the other end of the cable.
5Repeat this procedure for additional Garmin Marine Network cables as needed.
