press the right arrow key. Next, highlight the “Position Format” label and
press the right arrow key. A screen similar to the one at the bottom of the
previous page appears. Highlight the desired position format then press
the EXIT key to select the format and erase the menu.
NMEA / DGPS
The AirMap 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 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.
These receivers connect to the AirMap through the data port. DGPS gives
you more accurate positions than is otherwise possible.
Lowrance makes the “Lowrance DGPS Beacon Receiver” that receives
the DGPS signal broadcast by the Coast Guard at many locations around
the United States. One benefit of this system is that the Coast Guard
doesn’t charge for the use of this service. You can attach the DGPS Bea-
con Receiver to your AirMap and start using it immediately. However,
please note that the Lowrance DGPS Beacon Receiver is designed for
permanent mount on a boat or other vehicle. It requires a four to eight-foot
whip antenna.
See the sample wiring diagrams on the next page for general wiring pro-
cedures. You’ll need to purchase a NDC-1 adapter cable for your AirMap
Sport’s data port to connect to the DGPS receiver.
(Note: Connecting power to the AirMap through
the NDC cable as shown in the diagrams is op-
tional. However, the shield wire must still be con-
nected to ground.) Once the cables are wired, turn
the AirMap on, press the menu key, and select
NMEA / DGPS from the System Setup menu. A
screen similar to the one at right appears.
NMEA 0183 OUTPUT
To turn the NMEA output on, highlight the “NMEA 0183 OUTPUT” menu,
then press the right arrow key. If the other equipment works, then no setup
will need to be performed. If your the equipment doesn’t recognize the
NMEA data being sent by the GPS receiver and the wiring is correct, then
you may need to change the NMEA or the serial communication settings.
