Item Description Important Considerations
Helm control
(or compatible
Garmin chart
plotter)
A dedicated helm control is not included in all autopilot packages. If you install the
autopilot without a dedicated helm control, the autopilot CCU must be connected
to the same NMEA 2000
®
network as a compatible Garmin chartplotter to configure
and control the autopilot system.
NMEA 2000
power cable
You should install this cable only if you are building a NMEA 2000 network. Do not
install this cable if there is an existing NMEA 2000 network on your boat.
You must connect the NMEA 2000 power cable to a 9 to 16Vdc power source.
NMEA 2000
network
You must connect the helm control or compatible Garmin chartplotter and the CCU
to a NMEA 2000 network using the included T-connectors (NMEA 2000 Connection
Considerations, page8).
If there is not an existing NMEA 2000 network on your boat, you can build one using
the supplied cables and connectors (Building a Basic NMEA 2000 Network for the
Autopilot System, page17).
ECU
The ECU must be located within 0.5m (19in.) of the pump.
The cables connecting the ECU to the pump cannot be extended.
CCU
You can mount the CCU in a non-submerged location near the center of the boat, in
any orientation (CCU Mounting and Connection Considerations, page7).
Mount the CCU away from sources of magnetic interference.
ECU power cable
You must connect the ECU to a 12 to 24Vdc power source. To extend this cable, use
the correct wire gauge (Power Cable Extensions, page12).
CCU cable
To extend this cable to reach the ECU, you may need to use cable extensions (sold
separately) (CCU Mounting and Connection Considerations, page7).
You must connect this cable to the alarm and the Shadow Drive
™
sensor.
Pump
The pump must be located within 0.5m (19in.) of the ECU.
The cables connecting the pump to the ECU cannot be extended.
Alarm
The alarm provides audible alerts from the autopilot system, and you should install it
near the primary helm station (Installing the Alarm, page16).
Shadow Drive
sensor (optional)
Autopilot switch
(not included)
You must install the Shadow Drive sensor properly in the hydraulic steering line, and
connect it to the CCU cable (Installing the Shadow Drive Sensor, page16).
If your autopilot package does not include a Shadow Drive sensor, you should install
a manual Single Pole Single Throw (SPST) switch (not included) to disable the
autopilot if necessary.
