Chapter 2: Installing the Display Unit 17 1 2 D7734-1 Power Connector Pin No. 1 2 3 Function Battery positive (12 VDC systems) Battery negative Shield (drain wire) Color Red Black 3 No insulation Power Supply The A65 is intended for use on boat's DC power systems rated from 10. 7 to 18 VDC. The power connection to the unit should be made at either the output of the battery isolator switch or at a DC power distribution panel. Power should be fed directly to the A65 via its own dedicated cable system and protected by a thermal circuit breaker or fuse on the red (positive) wire that is installed close to the power connection. CAUTION: Dedicated Power Connection The A65 also supplies power for the GPS and sounder units (if so equipped). To minimize succeptibility to display flickering due to power fluctuations, provide the display unit with its own dedicated connection to boat's power. The RED wire must be connected to the feed from the positive (+) battery terminal and the BLACK wire to the feed from the negative (­) battery terminal. The shield wire (drain) should be connected to the boat's RF ground. CAUTION: Fuse Protection Install a fast blow 4 amp fuse on the red (positive) wire. If a longer power cable run is required, use the supplied power cable to connect to the display unit. Then use a suitable connector block to connect the free end to the extension cable, taking particular care to ensure the correct polarity. 18 A65 Installation Manual Use commonly practiced methods to determine proper wire gauge based on wire length, current, and wire tables. You may also trim the power cable supplied with the A65 to reduce overall wire length. Only use enough wire to connect the unit to the power source, including a service loop. Note: When the A65 has been powered off using the PWR key but is still electrically connected to the power supply, the GPS continues to draw current. The supplied power cable has a cross section of 10 mm. CAUTION: Correct Polarity If the power connections are accidentally reversed the system will not work. Use a multimeter to ensure that the input power leads are connected for correct polarity. NMEA Cable (R08004) The 5-pin, 1. 5m (5 ft) NMEA input cable is supplied with exposed wire connecting tails. These should be connected to your existing NMEA instruments using suitable connector blocks as follows: Function NMEA Input (-ve) common NMEA Input (+ve) NMEA Output (+ve) NMEA Output (-ve) common Not connected Color Green White Yellow Brown Screen Pin no. 1 2 3 4 5 2 1 3 4 D7735-1 5 GPS Cable Connect the 6-pin RS12 cable to the left-most connector, labeled GPS. 19 Chapter 3: Installing the GPS Antenna The RS 12 package contains the following items: 1. Low profile GPS Receiver, with 10 m (33 ft) cable 2. Mounting studs (x2) and thumb nuts (x2) 4. [. . . ] When complete, the following message appears: "Upgrade Completed. The UPGRADE and REBOOT soft keys now replace the text. Install any other upgrades as needed, using procedures listed above. When finished, remove the Compact Flash card from the A65 card reader and press REBOOT. [. . . ]
