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, we don‟t provide it, picture is shown as below ), then realizing trace playback via FYGCS. The Hornet-OSD can be connected to the FY-21AP, FY-31AP, FY-3ZT or Panda 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, Panda 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.

Interface Schematic Diagram:

① 1. DANGER: The three “VCC” ports (positive) for Video In, Video Out and Power In 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.

List of Interfaces

Application diagram

The Hornet-OSD can directly connect to the data output port of FY-21AP /FY-31AP

/FY-3ZT/ Panda, 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.

Interface introduction

The telemetry data display is as follows:

Error Coefficient Assessment（Attitude measurement error coefficient assessment）

1. Attitude measurement error coefficient is an assessment (ECA) of the aircraft attitude as

measured by FY-21AP /FY-31AP /FY-3ZT/ Panda.

2. “0” value is normal, maximum value is “1000”.

3. The higher the ECA is, the more error in autopilot attitude control will be.

4. If this coefficient continues to increase to 1,000 in the flight, this indicates the FY-21AP

/FY-31AP /FY-3ZT/ Panda do not meet the requirements of automated flight, so flight control will be transferred back to you (manual flight or RC mode).

5. This is usually caused by installations that result in high vibrations or shock to the FY-21AP

/FY-31AP /FY-3ZT/ Panda. You will need to check or adjust the autopilot installation to reduce vibration.

Mode C: Radar Positioning Function

 Display Modes selection

The OSD can be controlled to show different display information via one spare channel of your radio Rx. There are 5 optional display modes controlled by the different PWM signals. You can use default mode if you do not want to change the display modes.

How to change the display modes:

You can use a 2-way switch to change the display modes, the PWM signal of the 2-way switch is 900μs ～ 1200μs and 1800μs ～ 2100μs (in order to describe the frequency range conveniently , the PWM signal “900μs ～1200μs” might be called “L” for short , and “1800μs ～ 2100μs” might be called “H” for short. ).

The default mode is “A. All information displayed”, if you want to change to “B. Default Mode With artificial horizon”, just operate as following: first the switch is required to be played to “L”, then to “H”, you have changed the display mode for one time by this. Save the information after changing. When the OSD powers down and restarts, it will continue to keep in the display Mode B.

That is to say, you can change the display mode for one time by switching the “L” to “H”, the five display modes can be selected by circling in turn like this. (Note: the fifth display mode is “E. Remove All Information”)

Mode B is default when a jumper is used in the SW connector and power for the Hornet-OSD.

 The modes are shown as below:

Mode A: All Information Displayed

Mode D: Brief Mode

Mode B: Partial Display With Artificial Horizon Note: 9:Relative altitude (Unit : meter)

A. When connect with the autopilot or FY-31AP will display the barometer altitude. B. When only GPS Receiver is connected to the Hornet, GPS Altitude will be

displayed.

 Data record of FY-21AP, FY-31AP, FY-3ZT, Panda and GPS module

Hornet-OSD can automatically record the information of FY-21AP, FY-31AP, FY-3ZT

Panda or GPS Receiver connected to it via an inserted MICRO SD card.

Data naming:

If no data is received by Hornet OSD, the recorded data is noted at “FEIYU***.txt”.

(“ *** ” is a running number from 000 to 999), for example, “FEIYU001.txt”. If 4 GPS

satellites or more are detected, the file will automatically be renamed after the date and time of flight (month, day, hour and minute). For example, if the date is Nov 14, eight minutes pass eight, the name will be “11140808.txt”.

 Flight mode

When in the NAV mode (for FY-21AP: Fixed Altitude flying mode; for FY-3ZT/FY-31AP/ Panda: Air route fly mode), it will display not only the letter “NAV” on the overlay interface, but also the current waypoint every two seconds, so circulates.
