AP 117 OSD operation manual
Dear customers:
Hello! Thank you for purchasing the AP117 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 AP117 OSD overlays flight telemetry information onto your video image. The telemetry
information displayed includes altitude, flight speed, flight direction, and home direction. The AP117 can
be connected to the FY-21AP and FY-3ZT systems to display autopilot telemetric data, or to a GPS
receiver to display positioning data.
AP117 automatically adapts to either PAL or NTSC video input. The adaptive processes within
about 2S.
Working status explanation:
After connecting the power supply, the indicator LED light will be activated. The AP117 will
automatically detect the incoming video (NTSC or PAL).The "NTSC" or "PAL" will overlaid on the
screen when the video signal is formatted. If receive signal from FY-21AP FY-3ZT or the GPS module,
the working indicator of AP117 OSD will begin to flash.
Once the input video is detected even if there is interruption to the video signal, the telemetry data of
the AP117 will continue to be transmitted via the video stream.
Interface introduction
The telemetry data is as bellowing:
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 FY-21AP module.

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 or FY-3ZT.
2. “0” value is normal, maximum value is “1000”.
3. The higher the ECA the more error in autopilot attitude control.
4. If this coefficient continues to increase to 1,000 in the flight, this indicates the FY-21AP or FY-3ZT
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 FY21AP or
FY3ZT. You will need to check or adjust the autopilot installation to reduce vibration.
Introduction for the flight State of FY-21AP or FY-3ZT
Display Modes
The OSD can be controlled to show different desiplay imformations via one spare channel of your
radio Rx. There are 5 optional desplay modes controlled by the different PWM signals. You can use
default mode if you do not want to change the display modes.Mode B is default when the SW
connector left unconnected.Mode C is default when a jumper is used in the SW connector.

Application diagram
A P117 OSD can directly connect to the data output port of FY-21AP or FY-3ZT , or separately connect
to the output port of GPS module, and then overlay the flight data information to the video signal.
Note:in the Figure4 the modules in the imaginary line frame means that you can choose any one of these
modules to connect .
