User manual LOWRANCE LGC-3000 GPS MODULE

[. . . ] 988-0154-651 LGC-3000, LGC-Baja Installation Instructions This instruction sheet tells how to install your LGC-3000 or LGC-Baja GPS module and connect it to a NMEA 2000® network using LowranceNETTM network components. The LGC-Baja is a ruggedized module designed to withstand the rigors of offroad automobile racing. It works just like the LGC-3000, and for simplicity we will only refer to the LGC-3000 in the rest of this instruction sheet. The LGC-3000 GPS module, like the other Lowrance Electronic Probe (EP) sensors, is designed only for use with a NMEA 2000 Network. [. . . ] Depending on your configuration, this three-branched cable could be the power source for the GPS module. The thicker two-wire cable branch (red and black) is the power supply for the display unit. 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. Depending on your configuration, you may not use all of these wires. 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. Failure to use a 3-amp fuse will void your warranty. 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.
