GHP 20 Installation Instructions 3
GHP 20 Package Contents and needed
tools
The GHP 20 autopilot system consists of multiple components.
Familiarize yourself with all of the components before beginning
installation. You must know how the components operate together in
order to correctly plan the installation on your boat.
As you familiarize yourself with the GHP 20 components, confirm that
your package includes the components identified below. If any parts are
missing, contact your Garmin dealer immediately.
Record the serial number of each component in the space provided.
Main Components
The GHP 20 autopilot system consists of two main components, the
Course Computer Unit (CCU), and the GHC
™
10 user control interface.
CCu
The CCU acts as the brain of the GHP 20. The CCU contains the
sensory equipment used to determine heading. The CCU connects to the
steering system of your boat. The CCU also connects to a NMEA 2000
®
network to communicate with the GHC 10, and to optional NMEA
2000-compatible GPS devices ( page 8 ).
Serial number
GHC 10
The GHC 10 is the primary interface used to operate the GHP 20
autopilot system. Using the GHC 10, you engage and steer the GHP 20.
You also set up and customize the GHP 20 using the GHC 10.
The GHC 10 connects to a NMEA 2000 network to communicate
with the CCU. The GHC 10 also connects with optional NMEA
2000-compatible devices, such as a GPS device, to use advanced
features of the GHP 20. If NMEA 2000-compatible devices are
not available, you can connect the GHC 10 to optional NMEA
0183-compatible devices instead.
Serial number
Cables and Connectors
The GHP 20 autopilot system includes multiple cables. These cables
connect the components to power, to each other, to an alarm, and to
optional devices.
Steering Controller Cable
Notice
Do not connect the steering controller cable to a NMEA 2000 network.
The GHP 20 requires a powered CAN bus to communicate with the
steering controller. Ensure that the steering controller CAN bus is
properly powered and terminated. Consult the boat manufacturer if
needed.
This cable connects the CCU to the steering system of the boat. A
portion of this cable contains color-coded wires with bare ends. These
wires connect the CCU to the alarm.
alarm
The alarm provides audible alerts from the GHP 20 ( page 7 ).
GHC 10 nMEa 0183 Data Cable
Included in the GHC 10 box, this cable can be used to connect the
GHC 10 to optional NMEA 0183-compatible devices ( page 10 ).
nMEa 2000 Cables and Connectors
The NMEA 2000 cables connect the CCU and the GHC 10 to the
NMEA 2000 network. Either connect the CCU and the GHC 10 to an
existing NMEA 2000 network using the included T-connectors and drop
cables, or use all of the included NMEA 2000 cables and connectors to
build a NMEA 2000 network on your boat if needed ( page 8 ).
