For example, if you have to extend the power cable to the battery or
power buss, attach one end of the fuse holder directly to the battery or
power buss. This will protect both the unit and the power cable in the
event of a short. It uses a 3-amp fuse.
Power connections for the IntelliMap 480 GPS unit.
CAUTION:
Do not use this product without a 3-amp fuse wired into the power
cable! Failure to use a 3-amp fuse will void your warranty.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.
An optional 8-foot, CA-4 external power cable with a cigarette lighter
adapter is available from Eagle.
NMEA/DGPS Cable Connections
NMEA is a standard communications format for marine electronic
equipment. For example, an autopilot can connect to the NMEA inter-
face on the IntelliMap 480 and receive positioning information. The In-
telliMap 480 can exchange information with any device that transmits
or receives NMEA 0183 data.
DGPS is an acronym for the Differential Global Positioning System.
DGPS supplements and boosts the accuracy of basic GPS. DGPS was
developed by the U.S. Coast Guard, which is responsible for the sys-
tem's operation in the United States. Since it's creation, DGPS has be-
come the international maritime standard for marine navigation.
The most popular DGPS system relies on a grid of ground-based trans-
mitters that send correction signals to DGPS receivers. These in turn,
connect to the GPS receiver (such as the IntelliMap 480). Eagle offers
an optional DGPS receiver for your unit.
