• If your boat does not already have a NMEA 2000 network, one can be built using the included NMEA 2000 cables and connectors (Building a Basic NMEA 2000 Network for the Autopilot System, page 8). • To use the advanced features of the autopilot, optional NMEA 2000 devices, such as a wind sensor, a water-speed sensor, or a GPS device, can be connected to the NMEA 2000 network. Power and Data Layout WARNING When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product specifications. In addition, connecting the power cable without the appropriate fuse in place voids the product warranty. Item Description Helm control À (or compatible Garmin chartplotter) Helm control Á data cable NMEA 2000 Â power cable NMEA 2000 Ã network Important Considerations 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. This cable should be installed only if you are connecting the autopilot to optional NMEA 0183 devices, such as a wind sensor, a water-speed sensor, or a GPS device (NMEA 0183 Connection Considerations, page 9). This cable should be installed 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. The NMEA 2000 power cable must be connected to a 9 to 16 Vdc power source. The helm control or compatible Garmin chartplotter and the CCU must be connected to a NMEA 2000 network using the included Tconnectors (NMEA 2000 Connection Considerations, page 2). 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 8). Item Description ECU Ä CCU Å ECU power Æ cable CCU cable Ç Pump È Alarm É Shadow Drive (optional) Autopilot switch (not included) Important Considerations 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. The CCU can be mounted in a non-submerged location near the center of the boat, in any orientation (CCU Mounting and Connection Considerations, page 2). The CCU must be located away from sources of magnetic interference. The ECU must be connected to a 12 to 24 Vdc power source. To extend this cable, use the correct wire gauge (Power Cable Extensions, page 7). To extend this cable to reach the ECU, extensions (sold separately) may be necessary (CCU Mounting and Connection Considerations, page 2). This cable connects to the alarm and the Shadow Drive. 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. The alarm provides audible alerts from the autopilot system, and should be installed near the primary helm station (Installing the Alarm, page 8). The Shadow Drive must be installed properly in the hydraulic steering line, and connected to the CCU cable (Installing the Shadow Drive, page 8). If your autopilot package does not include a Shadow Drive valve, you should install a manual Single Pole Single Throw (SPST) switch (not included) to disable the autopilot if necessary.
