NMEA / DGPS
This product transmits data through the power/data port
in the back of the unit using NMEA 0183 format, ver-
sion 1.5 or 2.0. The data is used by other electronic
devices such as marine autopilots for position and steering 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 GlobalNav 212 are made through the power
cable. See the sample wiring diagrams on the next page for general wir-
ing procedures. Read your other product’s owner’s manual for more wir-
ing information.
Once the cables are wired, turn the unit on, press the menu key, and
select NMEA / DGPS CONFIG from the System Setup menu. A screen
similar to the one shown below appears.
NMEA Output
To turn the NMEA output on, highlight the “NMEA OUTPUT” menu (shown
at the bottom of the previous page), then press the right arrow key. If your
other equipment works, then no setup will need to be performed. If your
other equipment doesn’t recognize the NMEA data being sent by the Glo-
balNav 212 and the wiring is correct, then you may need to change the
NMEA or the serial communication settings.
Configure NMEA Output
Highlight the “Configure NMEA Output” menu, then
press the right arrow key. A screen similar to the one at
the top of page 40 appears.
NMEA 0183 Version
There are two versions of the NMEA data, 1.5 and 2.0.
If your other equipment requires 2.0, press the right
arrow key to select it.
