Hornet-OSD Manual
Dear customers:
Hello! Thank you for purchasing the OSD of Guilin Feiyu Electronic Technology Co,
Ltd. In order to achieve full potential and safe operation of this product, please carefully
read this manual prior to installation.
Preface
The Hornet-OSD overlays flight telemetry information onto your video image. The
telemetry information displayed includes flight altitude, flight speed, flight direction, and
home direction and so on. You also can save the telemetry information to a MICRO SD
card (
you should buy the card by yourself, for we don
’
t offer it, picture is shown as below
),
then realizing trace playback via FYGCS. The Hornet-OSD can be connected to the
FY-21AP, FY-31APand FY-3ZT systems to display autopilot telemetric data, or to a GPS
receiver to display positioning data.
Hornet-OSD automatically adapts to either PAL or NTSC video input and confirms if
there is a MICRO SD card or not. The adaptive processes are within about 20 seconds.
Working status explanation:
After connecting the power supply, the indicator LED light will be activated. The
Hornet- OSD will automatically detect the incoming video (NTSC or PAL).The "NTSC" or
"PAL" will overlaid on the screen when the video signal is detected. If Data is received
from the autopilot (FY-21AP, FY31AP, FY-3ZT or GPS module) the LED indicator of
Hornet- OSD will begin to flash. If not, the Hornet-OSD will automatically restart after
waiting for 20 seconds.
Once the input video is detected even if there is interruption to the video signal, the
telemetry data of the Hornet- OSD will continue to be transmitted via the video stream.

are all
inter- connected. Therefore you are allowed to connect ONE input voltage only.
DO NOT
input more than one power supply or damage to the OSD will occur.
2. It is recommended to power the OSD independently to ensure a clean video display.
3. Note that power to the OSD is not supplied by the Autopilot module. Power is via the 12 volt
input.

Application diagram
The Hornet-OSD can directly connect to the data output port of FY-21AP, FY-31AP or
FY-3ZT, or separately connect to the output port of GPS module, and then overlay the flight
data information to the video signal. The application diagram is shown as bellow.
Note
：
The modules in the imaginary line frame means that you can choose any one of these
modules to connect.
