Dragon Link OSD Setup Instructions:
Download the firmware package below for the firmware and configuration utility. All Dragon Link OSD's shipped after January 2018 already have the latest firmware on them. Updating the firmware on OSD's that have shipped after January 2018 again is NOT recommended as it will serve no benefit, and could possibly introduce errors. Only update your OSD's firmware if it was shipped prior to January 2018.
HARDWARE SETUP - Connect your OSD
STEP 1: Connect your video camera video output using supplied cable and connect it to the CAMERA connector as shown in the picture to the left.
STEP 2: Connect your video transmitter video input using the supplied cable and connect it to the Vid TX connector on the OSD as shown in the picture to the left.
STEP 3: Connect a regulated 5 - 6 volt power source from your flight controller or other regulated 5 - 6 volt source to the orange wire of the supplied 5 pin UEXP data cable as shown in the picture to the left. WARNING: Power must be 5 - 6 volts, connecting higher voltages will burn out the OSD.
STEP 4: Connect the Dagon Link OSD to a serial port of your flight controller using the Black and Yellow wire of the supplied 5 Pin UEXP data cable as shown in the picture to the left. You can connect the OSD to any available serial port of your flight controller. For this example, we are using serial port 1.
You have now connected the Dragon Link OSD to your system, you should see a BLUE and GREEN LED on the OSD as well as see the text overlay on your video when you power the system on. Proceed to the next section below to configure your OSD.
