Garmin GHP Compact Reactor Hydraulic Installaiton Instructions

Contents

1 Connect the three T-connectors À together side-by-side.2 Connect the included NMEA 2000 power cable Á to a 9 to12 Vdc power source Â through a switch Ã.You should connect the power cable to the ignition switch ofthe boat if possible, or route it through an inline switch (notincluded).NOTE: The braided drain wire (bare) on the NMEA 2000power cable must be connected to the same ground as theblack wire on the NMEA 2000 power cable.3 Connect the NMEA 2000 power cable to one of the T-connectors.4 Connect one of the included NMEA 2000 drop cables Ä toone of the T-connectors and to the helm control (optional) orto a compatible Garmin chartplotter Å.5 Connect the other included NMEA 2000 drop cable to theother T-connector and to the CCU Æ.6 Connect the male and female terminators Ç to each end ofthe combined T-connectors.Connecting the Autopilot Components to an Existing NMEA2000 NetworkA dedicated helm control is not included in all autopilotpackages. If you install the autopilot without a dedicated helmcontrol, the autopilot CCU must be connected to the sameNMEA 2000 network as a compatible Garmin chartplotter toconfigure and control the autopilot system.1 Determine where to connect the CCU À and the helm control(optional) Á to your existing NMEA 2000 backbone Â.2 In the location where you plan to connect the CCU,disconnect one side of a NMEA 2000 T-connector Ã from thenetwork.3 If necessary, connect a NMEA 2000 backbone extensioncable (not included) to the side of the disconnected T-connector to extend the NMEA 2000 network backbone.4 Add an included T‑connector for the CCU to the NMEA 2000backbone by connecting it to the side of the disconnectedT‑connector or backbone extension cable.5 Route the included drop cable Ä to the CCU and to thebottom of the T-connector added in step 4.If the included drop cable is not long enough, you can use adrop 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 theAutopilot SystemYou can use advanced features of the autopilot system byconnecting optional NMEA 2000 compatible devices, such as awind sensor, a water-speed sensor, or a GPS device to theNMEA 2000 network.NOTE: You can connect optional devices that are not NMEA2000 compatible to the helm control through NMEA 0183(NMEA 0183 Connection Considerations, page 9).1 Add an additional T-connector (not included) to the NMEA2000 network.2 Connect the optional NMEA 2000 device to the T-connectorby following the instructions provided with the device.ConfigurationThe autopilot must be configured and tuned to your boatdynamics. You can use the Dockside Wizard and the Sea TrialWizard on the helm control or a compatible Garmin chartplotterto configure the autopilot.See the included configuration guide for more information onconfiguring the autopilot.AppendixNMEA 0183 Connection DiagramsThe helm control is not included in all autopilot packages. Ahelm control must be installed in your autopilot system toconnect NMEA 0183 devices according to these diagrams. Ifyou install the autopilot without a helm control, all NMEA devicesyou plan to use with the autopilot system must be connected toa compatible Garmin chartplotter on the same NMEA 2000network as the CCU. See the installation instructions providedwith your chartplotter for NMEA 0183 connection information.These wiring diagrams are examples of different situations youmay encounter when connecting your NMEA 0183 device to thehelm control.NMEA 0183 Connection Considerations• See the installation instructions for the NMEA 0183 device toidentify the transmit (Tx) A (+) and B (-) wires and receive(Rx) A (+) and B (-) wires.• Each internal Rx and Tx port has 2 wires, labeled A (+) and B(-) according to the NMEA 0183 convention. Thecorresponding A (+) and B (-) wires of each internal portshould be connected to the A (+) and B (-) wires of the NMEA0183 device. See the table and wiring diagrams whenconnecting the data cable to NMEA 0183 devices.• You must use 28 AWG, shielded, twisted-pair wiring forextended runs of wire. Solder all connections and seal themwith heat-shrink tubing.• See Specifications, page 11 for a list of the approvedNMEA 0183 sentences that are output by and input to yourdevice.9
