2 Move the compass six inches to the left of the location, then six inches to the right, observe the needle, and select an action: • If the compass needle moves more than three degrees during this step, magnetic interference is present. Select a new mounting location and repeat the test. • If the compass needle does not move, or moves less than three degrees, proceed to the next step. 3 Repeat this process while moving the compass above and below the mounting location. 4 Repeat this process while moving the compass in front of and behind the mounting location. ECU Mounting and Connection Considerations • The ECU can be mounted on a flat surface, facing any direction. • Mounting screws are included with the ECU, but you may need to provide different screws if the supplied screws are not suitable for the mounting surface. • The ECU must be mounted within 0.5 m (19 in.) of the pump. ◦ The cables connecting the ECU to the pump cannot be extended. • The ECU must be mounted in a location where it will not be submerged or exposed to wash down. • The ECU power cable connects to the boat battery, and it can be extended if needed (Power Cable Extensions, page 4). Shadow Drive™ Mounting Considerations NOTE: The Shadow Drive is a sensor you install in the hydraulic steering lines of your boat. It detects when you manually take control of the helm and suspends autopilot control of the boat. • The Shadow Drive must be mounted horizontally and as level as possible, with cable ties firmly securing it in place. • The Shadow Drive must be mounted at least 305 mm (12 in.) away from magnetic materials or devices, such as speakers or electric motors. • The Shadow Drive should be mounted closer to the helm than to the pump. • The Shadow Drive should be mounted lower than the lowest helm, but higher than the pump. • The Shadow Drive must not be connected directly to the fitting at the back of the helm. There must be a length of hose between the fitting at the helm and the Shadow Drive. • The Shadow Drive must not be connected directly to a hydraulic T-connector in the hydraulic line. There must be a length of hose between a T-connector and the Shadow Drive. • In a single-helm installation, there must not be a T-connector between the helm and the Shadow Drive. • In a dual-helm installation, the Shadow Drive should be installed between the pump and the hydraulic T-connector that leads to the upper and lower helm, closer to the Tconnector than to the pump. • The Shadow Drive must be installed in either the starboard steering line or the port steering line. The Shadow Drive must not be installed in either the return line or the high-pressure line, if applicable. Alarm Mounting and Connection Considerations • The alarm should be mounted near the primary helm station. • The alarm can be mounted under the dashboard. • If needed, the alarm wires can be extended with 28 AWG (0.08 mm2) wire. NMEA 2000® Connection Considerations • The CCU and the helm control must connect to a NMEA 2000 network. • 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 5). • 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 Helm control Á data cable NMEA 2000 Â power cable NMEA 2000 Ã network ECU Ä 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. You should install this cable 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 7). 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. 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 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 5). 2
