SELECT NMEA
The AccuNav Sport sends data out the white wire on the
optional NMEA cable according to standards set by the
NMEA (National Marine Electronics Association). This
allows the AccuNav Sport to send position and naviga-
tion information to “listener” units, such as charting
instruments, autopi-
lots, and other ma-
rine instruments. The
AccuNav Sport uses
the following NMEA
data protocols:
NMEA 0180 and
0183. NMEA 0180
sends steering infor-
mation only. It’s use-
ful mainly for marine
autopilots. NMEA
0183 sends position, steering, speed, and more. In
order to use this feature, the white wire on the optional
NMEA 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 informa-
tion.
The AccuNav Sport also has the capability to receive
differential data from a beacon receiver. This gives the
unit much better accuracy than normal. However, be-
fore purchasing and installing a beacon receiver, make
certain there are transmitters in the area you wish to
use. Presently, the AccuNav Sport can use the Mag-
navox MX-50R or StarLink MRB-2A. Please note that
the AccuNav Sport doesn't send NMEA 0183 data when
the Magnavox MX-50R beacon receiver is activated.
