Hornet-OSD Manual
Dear customers:
Hello!ThankyouforpurchasingtheOSD of GuilinFeiyuElectronicTechnologyCo,
Ltd. Inordertoachievefull potential andsafeoperationof thisproduct,pleasecarefully
readthis manual priortoinstallation.
Preface
TheHornet-OSDoverlaysflighttelemetryinformationontoyourvideoimage.The

Workingstatusexplanation:
Afterconnectingthepowersupply,theindicatorLEDlightwillbeactivated.The
Hornet-OSDwillautomaticallydetecttheincomingvideo(NTSCorPAL).The"NTSC"or
"PAL"will overlaidonthescreenwhenthevideosignalisdetected.IfData isreceived
fromtheautopilot(FY-21AP,FY31AP,FY-3ZT orGPS module)theLEDindicatorof
Hornet-OSDwill begintoflash.Ifnot,theHornet-OSD will automaticallyrestartafter
waitingfor20seconds.
Once theinputvideoisdetectedevenifthereisinterruptiontothevideosignal,the
telemetrydata of theHornet-OSD will continue tobetransmittedvia thevideostream.
InterfaceSchematic Diagram:
1.DANGER:The three “VCC”ports(positive) for VideoIn, Video Out and PowerIn areall
inter- connected.Thereforeyouareallowed toconnect ONEinputvoltageonly. DO NOT
input morethanone powersupplyor damagetotheOSDwill occur.
2.It isrecommended topowertheOSD independentlytoensureacleanvideodisplay.
3.NotethatpowertotheOSDisnot suppliedbytheAutopilotmodule.Powerisviathe12volt
input.
