You can view data in three different formats: statute, nautical, and metric.
The default is statute. The chart below shows the settings for each.

Distance ..... miles ..................... nautical miles ....... kilometers
Speed ......... miles per hour ....... knots .................... kilometers per hour
Altitude ....... feet ........................ feet ....................... meters

The unit will also show bearing in degrees true
or magnetic, and the clock in 12 hour (a.m./p.m.)
or 24 hour formats.  The UltraMap can also show
water depth in feet, fathoms, or meters,  tempera-
ture in degrees Fahrenheit or Celsius, (tempera-
ture requires an optional temp sensor) .To change
a unit of measure, first select “Change Units” from
the System Setup menu. 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 fin-
ished, press the EXIT key.

NMEA/DGPS
This product transmits data through the power/data port in the back of the
unit using NMEA 0183 format, version 1.5 or 2.0. The 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.

See the installation section for cable connections. See the sample wiring
diagram below for general wiring procedures. Read your other product’s
owner’s manual for more wiring information.
