To set the output sentences to the factory default settings, press the
DEFAULTS ON key. To turn on only a select few sentences, press the
CLEAR ALL key, then turn the desired sentences back on.
To modify the unit's NMEA 0183 sentence output format, first follow the

following steps:
1. At the PORT 1 OUTPUT SETUP (SENTENCES) screen, display the list
of sentences, then press the EDIT key.
2. Press the CURSOR PAD to select the desired sentence.
3. Press the ON/OFF key.
4. Press the ACCEPT key.
5. Repeat for each sentence requiring modification. Press the RETURN
menu key to go back to the PORT OUTPUT SETUP screen.
Part of the NMEA 0183 standard requires that the equipment you are
interfaced to—the "listener"—know what type of device is transmitting the
data. The talker ID tells the listener that it is receiving information from a
navigation source (the 961) and not a communications or sensor device,
which transmit completely different—and therefore unusable—forms of
data.
The "talker ID" enables you to configure the 961's output data to tell the
listener it is receiving data from either a GPS (GP) navigator or Integrated
Instrument (II). The choice you make depends on what the listener device
is expecting.
1. Check the listener device's instruction manual to determine which
"talker ID" codes it will respond to.
