2 In the location where you want to connect the helm control, disconnect one side of a NMEA 2000 T-connector from the à network. 3 If necessary, connect a NMEA 2000 backbone extension cable (not included) to the side of the disconnected Tconnector to extend the NMEA 2000 network backbone. 4 Add an included T‑connector for the helm control to the NMEA 2000 backbone by connecting it to the side of the disconnected T‑connector or backbone extension cable. 5 Route the included drop cable to the helm control and to Ä the bottom of the T-connector added in step 4. If the included drop cable is not long enough, you can use a drop cable up to 6 m (20 ft.) long (not included). 6 Connect the drop cable to the helm control and the Tconnector. 7 Repeat steps 2 through 6 for the CCU. Connecting Optional NMEA 2000 Devices to the Autopilot System You can use advanced features of the autopilot system by connecting optional NMEA 2000 compatible devices, such as a wind sensor, a water-speed sensor, or a GPS device to the NMEA 2000 network. NOTE: You can connect optional devices that are not NMEA 2000 compatible to the helm control through NMEA 0183 (NMEA 0183 Connection Considerations). 1 Add an additional T-connector (not included) to the NMEA 2000 network. 2 Connect the optional NMEA 2000 device to the T-connector by following the instructions provided with the device. Configuring the Autopilot The autopilot must be configured and tuned to your boat dynamics. The Dockside Wizard and the Sea Trial Wizard on the helm control are used to configure the autopilot. These wizards walk you through the necessary configuration steps. The Dockside Wizard NOTICE If you perform the Dockside Wizardwhile your boat is out of the water, provide rudder-movement clearance to avoid damage to the rudder or other objects. You can complete the Dockside Wizard while the boat is in or out of the water. If the boat is in the water, it must be stationary while you complete the wizard. Performing the Dockside Wizard NOTICE If you have a boat with a power assist steering system, turn on the power assist steering system before performing the Dockside Wizard to avoid damaging the steering system. 1 Turn on the autopilot. The first time you turn on the autopilot, you are prompted to complete a short setup sequence. 2 If the Dockside Wizard does not start automatically after the setup sequence, select Menu > Setup > Dealer Autopilot Setup > Wizards > Dockside Wizard. 3 Select the vessel type. 4 Test the steering direction (Testing the Steering Direction). 5 If necessary, select the speed source (Selecting the Speed Source). 6 If necessary, verify the tachometer (Verifying the Tachometer). 7 Review the results of the Dockside Wizard (Reviewing the Results of the Dockside Wizard). Testing the Steering Direction 1 While moving at a low rate of speed, select and . When you select When you select right. , the rudder must turn the boat to the left. , the rudder must turn the boat to the 2 Select Continue. 3 Select an option: • If the steering test turns the boat in the correct direction, select Yes. • If the steering test turns the boat in the opposite direction, select No and repeat steps 1 though 3. Selecting the Speed Source Select an option: • If you connected a NMEA 2000 compatible engine (or engines) to the NMEA 2000 network, select Tach. - NMEA 2000 or Proprietary. • If NMEA 2000 tachometer data source is not available or unusable, select GPS as a speed source. • If you did not connect a NMEA 2000 tachometer or GPS device as a speed source, select None. NOTE: If the autopilot does not perform well using None as the speed source, Garmin recommends connecting a tachometer through the NMEA 2000 network or using a GPS device as the speed source. Verifying the Tachometer This procedure does not appear when GPS or None is selected as the speed source. With the engine (or engines) running, compare the RPM readings on the helm control with the tachometer (or tachometers) on the dashboard of your boat. If the RPM numbers do not align, there may be a problem with the NMEA 2000 speed source or connection. Reviewing the Results of the Dockside Wizard The helm control displays the values you chose when you ran the Dockside Wizard. 1 Examine the results of the Dockside Wizard. 2 Select any incorrect value, and select Select. 3 Correct the value. 4 Repeat steps 2-3 for all incorrect values. 5 When you are finished reviewing the values, select Done. 7
