NMEA 2000 and the Autopilot Components NOTICE If you have an existing NMEA 2000 network on your boat, it should already be connected to power. Do not connect the NMEA 2000 power cable to an existing NMEA 2000 network, because only one power source should be connected to a NMEA 2000 network. You can connect the helm control and the CCU through an existing NMEA 2000 network. If you do not have an existing NMEA 2000 network on your boat, all the parts needed to build one are supplied in the autopilot package (Building a Basic NMEA 2000 Network for the Autopilot System). To use advanced features of the autopilot, optional NMEA 2000 devices, such as a GPS device, can be connected to the NMEA 2000 network. If you are unfamiliar with NMEA 2000, you should read the "NMEA 2000 Network Fundamentals" chapter of the Technical Reference for NMEA 2000 Products. To download this document, select Manuals on the product page for your device at www.garmin.com. Building a Basic NMEA 2000 Network for the Autopilot System NOTICE If you are installing a NMEA 2000 power cable, you must connect it to the boat ignition switch or through another in-line switch. NMEA 2000 devices will drain your battery if the NMEA 2000 power cable is connected to the battery directly. 1 Connect the three T-connectors together side-by-side. À 2 Connect the included NMEA 2000 power cable to a 9 to Á 12 Vdc power source through a switch .  à Connect the power cable to the ignition switch of the boat if possible, or route it through an inline switch (not included). NOTE: The braided drain wire (bare) on the NMEA 2000 power cable must be connected to the same ground as the black wire on the NMEA 2000 power cable. 3 Connect the NMEA 2000 power cable to one of the Tconnectors. 4 Connect one of the included NMEA 2000 drop cables to Ä one of the T-connectors and to the helm control . Å 5 Connect the other included NMEA 2000 drop cable to the other T-connector and to the CCU . Æ 6 Connect the male and female terminators to each end of Ç the combined T-connectors. Connecting the Autopilot Components to an Existing NMEA 2000 Network 1 Determine where to connect the helm control and the CCU À to your existing NMEA 2000 backbone . Á  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. 4
