Units of Measure
The Expedition can show its data in many differ-
ent formats. For example, distance can be dis-
played in statute miles (MI), nautical miles (NM),
or kilometers (KM). The following can be changed
on the "Change Units" menu: (Defaults shown in
bold)
Clock ............... 12-hour (a.m.-p.m.), 24 hour
Distance .......... miles, nautical miles, kilometers
Speed .............. miles per hour, knots,
kilometers per hour
Bearing ............ magnetic, true
Altitude ............ feet, meters
To change a unit of measure, first select the "Change Units" label from the
"System Setup" menu. The screen shown above appears. Highlight the
desired selection, then press the left or right arrow key. You can change
any or all of the settings on this page. When you're finished, press the
EXIT key.
NMEA / DGPS
The Eagle Expedition transmits data through the data port in the back of
the unit using NMEA 0183 format, version 1.5 or 2.0. This data is used by
other electronic devices such as marine autopilots for position and steer-
ing information.
DGPS on the other hand, is a data input. DGPS is an acronym for Differ-
ential Global Positioning System. Currently, it relies on a system of ground-
based transmitters that send correction signals to small DGPS receivers.
DGPS gives you more accurate positions than is
otherwise possible.
All wiring connections to the Expedition are made
to it's power cable. See the sample wiring diagrams
on the next page for general wiring procedures.
Read your other product's owner's manual for
more wiring information.
Once the cables are wired, turn the Expedition
on, press the menu key, and select NMEA / DGPS
from the System Setup menu. A screen similar to
the one at right appears.
