TELEMETRY DATA OUTPUT
The models AIR Plus, AIR Pro and AIR Pro BT have the possibility to send data at high speed rate to external
devices (up to 8 updates per second). This function is very important, as the instrument can send in “real time”
all the flight’s info about altitude, anemometer, variometer and GPS data to various devices such as
Smartphone, Tablet, PDA , Car Navigators, Palm, and Pocket PC, to provide the pilot’s remote monitoring or,
through alert SMS for “search and rescue”.
The data can be sent via serial cable, USB or through Bluetooth, find further details on connections and
interfaces at chapter 14 "CONNECTIONS, INTERFACES & MEMORY CARD”.
To activate the real time telemetry output go to ADVANCED SETUP \ n. 24 TELE and select the data format
CAR, FL1 or FL2 .
