Garmin Compact Reactor 40 Hydraulic Autopilot with GHC 20 and Shadow Drive Pack - Page 7

NOTICE If you are connecting this device to an existing NMEA 2000 network, the NMEA 2000 network 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. If you are connecting this device to an existing NMEA 2000 network or engine network by another manufacturer, you should install a NMEA 2000 Power Isolator (010-11580-00) between the existing network and the Garmin devices. You can connect the CCU and the optional helm control 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, page 7). To use the 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. 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. 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 You should 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 (optional) or to a compatible Garmin chartplotter . 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 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. 1 Determine where to connect the CCU and the helm control À (optional) to your existing NMEA 2000 backbone . Á  2 In the location where you plan to connect the CCU, 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 CCU 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 CCU and to the Ä 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 CCU and the T-connector. 7 If needed, repeat steps 2 through 6 for the helm control (optional) or a compatible Garmin chartplotter. 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 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, page 8). 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. 7
