User manual LOWRANCE LGC-3000 GPS MODULE

[. . . ] The cable length from the connector to the GPS module is 18 inches (45. 7 cm). The module packs with: a 15 foot (4. 6 m) extension cable with a male connector on one end and a female connector on the other end; one red network T connector; as well as the parts needed for mounting the module on a flat surface or the optional pole mount. Some packages may include the QM-1 quick mount bracket, which is also available as an option. (The QM-1 includes its own instruction sheet, part 988-0154-502. ) The QM-1 is a quick-connecting, bayonet-style mounting device. [. . . ] The cable branch with three wires (red, black and shield) is the power cable for a NMEA 2000 network. It is labeled "NMEA 2000 POWER. " Typically, this branch is used to power the GPS module. The branch with 5 wires (blue, yellow, orange, green and shield) is a data cable, labeled "RS-232 COMM. " This allows your display unit to exchange NMEA 0183 data with another device, such as an autopilot, DSC marine radio or computer. Display unit power wires: red and black To unit NMEA 2000 power wires: red, black and shield Data cable wires: blue, yellow, orange, green and shield The Power/Data cable for the display unit used with the GPS module. NOTE: There are two basic power connection options, which are shown in the two diagrams on pages 7 and 8. Read the following instructions carefully to determine which power connection applies to your display unit and GPS module. Caution: All wires in the power/data cable have bare ends for easier installation. The bare ends on any unused wires should be capped with wire nuts or electrical tape to prevent an electrical short. Powering Your Display Unit Complete instructions for powering the display unit are in the unit's manual. Attach the display power cable (with provided 3-amp fuse) to a 12-volt DC accessory switch or power bus. The display unit power cable is shown connected to power in both Diagram A (page 7) and Diagram B (page 8). 6 WARNING: The display unit must be independently fused with the enclosed 3-amp fuse (or equivalent), even if you connect to a fused accessory or power bus. Powering Your GPS Module A NMEA 2000 network bus must be connected to a power source to operate. NMEA 2000 devices, including the LGC-3000 GPS module, draw their power from the network bus. The network and any NMEA 2000 devices, including the LGC3000 GPS module, will not operate unless the NMEA 2000 network is powered. The NMEA 2000 power cable must be connected to power even if your only NMEA 2000 device is the GPS module. (A display unit and a GPS module form a simple NMEA 2000 network. ) However, never connect multiple power sources to a NMEA 2000 network. If you have a network that is already powered, see diagram B on page 8.

Black wire Recommended power off switch 12 volt DC power source NMEA 2000 Power Cable Data Cable Use this method if you are only powering your display unit and are not powering a NMEA 2000 network or any NMEA 2000 accessory device, including a GPS module. The method in diagram B is also used when your display unit is connected to a NMEA 2000 network that is already connected to power. (Never connect multiple power sources to a NMEA 2000 network. ) Powering a NMEA 2000 Network Bus If you have a pre-existing NMEA 2000 network installation, it may already be connected to another power source. If you are not sure about a network's power status, consult the boat manufacturer or dealer. If your NMEA 2000 bus is already powered, you do not need to connect the NMEA 2000 Power cable. You can connect the LGC-3000 directly to the display unit or anywhere along the network and it will operate. If you do need to power your NMEA 2000 bus, attach the NMEA 2000 Power cable to an accessory switch as indicated in Power Diagram A on page 7. The NMEA 2000 Power cable's red wire should be attached (with provided 3-amp fuse) to the positive (+) terminal.
