SELECT NMEA
The LMS-350A sends data out the white wire on the power cable
according to standards set by the NMEA (National Marine Electronics
Association). This allows the LMS-350A to send position, depth, and
navigation information to “listener” units, such as charting instruments,
autopilots, and other marine instruments. The LMS-350A uses the
following NMEA data protocols: NMEA 0180 and 0183. NMEA 0180 sends
steering information only. It’s useful mainly for autopilots. NMEA 0183
sends depth, position, steering, speed, and more. In order to use this
feature, the white wire on the power cable must be connected to the NMEA
data input on the other instrument. See the installation section in the front
of this manual for wiring connection information.
The LMS-350A also has the capability to receive differential data from a
beacon receiver. This gives the unit much better accuracy than normal.
However, before purchasing and installing a beacon receiver, make
certain there are transmitters in the area you wish to use. Presently, the
LMS-350A can use the Magnavox MX-50R or StarLink MRB-2A. Please
note that the LMS-350A doesn't send NMEA 0183 data when the
Magnavox MX-50R beacon receiver is activated.
NMEA SETUP
Once you connect the wiring properly, the LMS-350A must be told which
NMEA data format to use. Con-
sult the owner’s manual of the
other equipment to see which
format it needs. Then set the
LMS-350A as follows:
First, press the MENU key.
Next, press the key next to the
“Change GPS Settings” label.
Now press the key next to the
“Select NMEA/DGPS” label.
The screen shown at right ap-
pears.
The data format currently in use shows at the top of the screen. To change
it, press the key next to the desired data output. Now press the CLEAR
key. The Accura will return to the last used GPS screen and send NMEA
data out the white wire on the power cable.
