The sentences that will be output are followed by the word
ON
, and those
that won’t be output are followed by two dashes to signify that they’re
turned off. Some devices can’t handle all these sentences correctly, so you
can use this screen to customize the output by turning individual sen-
tences to the
ON
or
DASHES
(off) setting. In general, you may want to
turn on only those sentences used by the particular equipment to which
you’re interfacing the 951/952.

Choosing the NMEA
0183 talker ID
Part of the NMEA 0183 standard requires that the equipment you’re
interfaced to—the “listener”—knows what type of device is transmitting
the data. The talker ID tells the listener that it is receiving information
from a navigation source (the 951/952), not a communications or sensor

NOTE:
The NMEA ON/OFF item list controls only the Version 2.01
GLL and BWC items, not the 1.5 version of these items. Thus,
ON/OFF changes made to the Version 1.5 GLL and BWC out-
put items have no effect on the data actually output.
