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.
Turning NMEA output sentences on and off
To turn on or off the unit's NMEA 0183 sentences, first follow the above
description to display the 0183 SENTENCE screen, then perform the fol-
lowing steps:
1. Press the &85625 3$' to highlight the sentence you want to turn
on or off, then press the (',7 menu key.
2. Press the &85625 3$' to toggle the sentence on or off, and press
(17(5 to make your selection (or &/($5 to leave it unchanged).
3. Repeat for each sentence as desired. When you're done, press the
5(7851 menu key to go back to the PORT SETUP screen.
The NMEA ON/OFF item list controls only the Version 2.01
GLL and BWC items, not the 1.5 version of these items. Thus,
ON/OFF changes made to the Version 1.5 GLL and BWC out-
put items have no effect on the data actually output.
If you want to set all the sentences to the factory settings for recom-
mended output, press the 6$)( 5(6(7 menu key.
If you want to turn on only a select few sentences for output, press the
$// 2)) menu key to turn off all sentences, then turn the desired ones
back on.
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
