The Power/Data cable for this unit.

Depending on your configuration, you may not use all of these wires.
(For example, many units cannot operate an optional external speaker,
so the white wire on the Power Supply cable isn't functional.) The fol-
lowing segments include instructions for installing all the wires that
you will use with this unit.

Powering a NMEA-2000 Buss
(NMEA-2000 Power cable)
A NMEA-2000 buss must be connected to a power source to operate. If
you have a pre-existing NMEA-2000 installation, it may already be
connected to another power source. If your NMEA-2000 buss is already
powered, you can ignore the NMEA-2000 Power cable. Never attach
two power sources to a single NMEA-2000 buss.

If you do need to power your NMEA-2000 buss, attach the NMEA-2000
Power cable to your boat's battery just as indicated in the following
segment for connecting your unit's Power Supply cable. The NMEA-
2000 Power cable's red wire should be attached (with provided 3-amp
fuse) to the boat battery's positive terminal, and the NMEA-2000 Power
cable's black and shield wires should both be attached to the battery's
negative terminal.

NOTE:

If the NMEA-2000 buss draws power directly from the boat's battery,
the LGC-Baja will remain on (drawing power) all the time. The LGC-
Baja's current draw is very small and shouldn't decrease the boat's
storage battery life, but if this small draw is a concern, you can in-
stall a switch between the NMEA-2000 buss and the battery.

Powering Your Unit
(Power Supply cable – red and black wires)
The unit works from a 12-volt battery system. For the best results, at-
tach the power cable directly to the battery. You can attach the power
cable to an accessory or power buss, however you may have problems
with electrical interference. Therefore, it's safer to go ahead and attach
the power cable directly to the battery.
