Installation Preparation

Before installing the GHP 10V autopilot system, you must plan where
all the components will be located on your boat. Temporarily place
all the components where you intend to install them. Read these
considerations before you begin planning your installation.
NOTE: There is an installation checklist on the last page of these
instructions. Remove the last page and refer to the checklist as you
proceed through the GHP 10V installation.

Mounting and Connection Considerations

The GHP 10V components connect to each other and to power using the
included cables. Ensure that the correct cables reach each component
and that each component is in an acceptable location before mounting
or connecting any components.

CCu Mounting Considerations

• The CCU must be mounted in the forward half of the boat, no
higher than 10 ft. (3 m) above the waterline.
• The CCU must not be mounted in a location where it will be
submerged or exposed to wash-down.
• The CCU must not be mounted near magnetic material,
magnets (speakers and electric motors), or high-current wires.
• The CCU must be mounted at least 24 in. (0.6 m) away from
movable or changing magnetic disturbances such as anchors, anchor
chain, wiper motors, and tool boxes.
• A handheld compass should be used to test for magnetic interference
in the area where the CCU is to be mounted.
If the handheld compass does not point north when you hold it in
the location where you intend to mount the CCU, there is magnetic
interference. Choose another location, and test again.
• The CCU can be mounted below the waterline if it is not in a
location where it will be submerged or exposed to wash-down.
• The CCU bracket must be mounted on a vertical surface or under a
horizontal surface, so that the connected wires hang straight down.
• Mounting screws are included with the CCU, but you may need to
provide different screws if the supplied screws are not suitable for
the mounting surface.

CCu Connection Considerations

• The CCU interconnect cable connects the CCU to the Autopilot
Gateway, and provides 9.5 ft. (3 m) of cable between the CCU and
the Autopilot Gateway.
◦ If the CCU cannot be mounted within 9.5 ft. (3 m) of the
Autopilot Gateway, NMEA 2000 cables can be used to extend
the connection.
◦ The CCU interconnect cable must not be cut.
• The CCU interconnect cable connects the CCU to the GHC 10 with
a single yellow signal wire
power on if this connection is not made.

alarm Mounting Considerations

• The alarm should be mounted near the helm station.
• The alarm can be mounted under the dashboard.

alarm Connection Considerations

• If needed, the alarm wires can be extended with 28 AWG (.08 mm
wire.

nMEa 2000 Connection Considerations

• The CCU and the GHC 10 connect to the NMEA 2000 network.
If your boat does not have a NMEA 2000 network, one can be built
using the included NMEA 2000 cables and connectors
(page 10).
• To use advanced features of the GHP 10V, optional NMEA
2000-compatible devices, such as a GPS device, can be connected to
the NMEA 2000 network.

GHC 10 Mounting Considerations

• The mounting location should provide optimal viewing as you
operate your vessel.
• The mounting location should allow easy access to the keys on the
GHC 10.
• The mounting surface must be strong enough to support the weight
of the GHC 10 and protect it from excessive vibration or shock.
• The area behind the surface must allow room for the routing and
connection of the cables.
There should be at least a 3-inch (8 cm) clearance behind the case of
the GHC 10.
• The location must be at least 9
compass, to avoid interference.
• The location must be in an area that is not exposed to extreme
temperature conditions (page

GHC 10 Connection Considerations

• You must connect the GHC 10 to the NMEA 2000 network.
• For the autopilot to function, you must correctly connect two wires
from the GHC 10 data cable:
◦ The yellow wire from the GHC 10 data cable must be connected
to the yellow wire of the CCU interconnect cable.
◦ The black wire from the GHC 10 data cable must be connected
to the same ground as the CCU.
• Optional NMEA 0183-compatible devices, such as a GPS device,
can be connected to the GHC 10 data cable
