If interfacing the aera with another piece of equipment (such as an autopilot), the
unit needs to be set to output NMEA data. If the NMEA output mode is set to 'Fast',
the unit will output a minimum number of NMEA sentences at 1-second intervals. If
the NMEA output is set to 'Normal', the unit will output a greater number NMEA
sentences as 2-second intervals.
Setting NMEA output mode:
1) From the Main Menu, touch Tools > Setup > Interface.
2) Touch Serial Data Format. A vertical list is displayed.
3) Touch 'NMEA Out'.
4) Touch NMEA Output Mode to toggle between 'Normal' or 'Fast'.
NMEA Sentence Output:
• Normal Mode: GPRMB, GPRMC, GPGGA, GPGSA, GPGSV, GPGLL, GPBWC,
GPVTG, GPXTE, GPBOD, GPRTE, GPWPL, GPAPB, PGRME, PGRMZ, PGRMM,
and PGRMH.
• Fast Mode: GPRMB, GPRMC, PGRMZ, and PGRMH.

CONNECTING TO A GTX 330 MODE S TRANSPONDER

To receive Mode S TIS-A traffic data from a GTX 330 transponder on your aera,
connect an available RS-232 OUT wire on the transponder to the Data In wire on the
aera. (You do not need to connect the transponder to the aera's Data Out wire.) Then,
set the corresponding RS-232 output configuration on the transponder to REMOTE +
TIS-A and set the aera's Serial Data Format to GTX TIS-A In or GTX TIS-A In/NMEA &
VHF Out. For more information see the GTX 330 Transponder Installation Manual.
Configuring TIS-A input:
1) Connect the aera to the GTX 330 using the Aviation Bare Wire Connector
(optional accessory).
2) From the Main Menu, touch Tools > Setup > Interface.
3) Touch the Serial Data Format Button. A vertical list is displayed.
