7. The Data Radio uplink is responsible for receiving flight navigation data from the GCS. At
the same time, the Data Radio also transmits flight status and other remote sensing
information back to the GCS. The asynchronous serial interface protocol between PANDA
autopilot and communications link is RS232-TTL level, the baud rate is 19200.
8. Place the Data Radio module as far as possible away from the GPS module, AHRS, GPS and
servos in order to avoid interference to these equipments. The Data Radio antennas should be
installed vertically upward or downward.
9. The Data Radio communication link range depends on your specific application. If your
aircraft will only be operated within a 5km radius then the FY-606 radio modem will be
sufficient. If you wish longer range then the FY-605 radio modem should be selected.
10. Also consider your Data Radio frequency selection based on your existing radio control
system, to avoid frequency interference.
11. Alternately, you can utilize your own full duplex data modem. The communication link used
by PANDA autopilot can be either a half-duplex or a full-duplex data modem.
12. Warning: Certain frequency bands from the Data Radio (e.g. 433 mHz) can interfere with
servos due to electromagnetic emission. To resolve this issue either avoid placing the Data
Radio transmitter close to sensitive components or use a magnetic core (as shown below) to
reduce the interference.
