CONNECT RECEIVER TO FLIGHT CONTROLLER
See the pictures to the left to connect the newer Dragon Link Receiver UEXP 6 pin connector to the telemetry pins of your flight controller that does not have CTS / RTS connections.
1. Connect the Black Dragon Link GROUND wire to the telemetry ground of your flight controller.
2. Connect Dragon Link Blue Serial IN wire to TX on your flight controller.
3. Connect the Dragon Link White Serial OUT wire to RX on your flight controller.
4. Do not Connect the Yellow wire to anything.
5. Do not Connect the Green Wire to anything.
6. DO NOT connect the Dragon Link RED wire to anything, you will burn something out if you do this !!!
CONFIGURATION: Ardupilot and Mission Planner.
We strongly recommend loading the latest ArduPilot firmware on to your flight controller. Even though Dragon Link will work with INAV and other flight controller software... ArduPilot is better in every way, flys better, less crashes, more reliable, more features. ArduPilot is industrial grade software that you can get for free !!!!
1. Connect your flight controller to Mission Planner, and select CONFIG at the top, and then click " Full Parameter List " on the left. You will see a large list as in the picture. Change the following Parameters:
BRD_SER1_RTSCTS = 0 ( This options may not appear on controllers that do not have CTS / RTS connections )
SERIAL1_BAUD = 38
SERIAL1_PROTOCOL = 2
SR1_EXT_STAT = 1
SR1_EXTRA1 = 5
SR1_EXTRA2 = 5
SR1_EXTRA3 = 1
SR1_PARAMS = 10
SR1_POSITION = 3
SR1_RAW_CTRL = 1
SR1_RAW_SENS = 1
SR1_RC_CHAN = 1
2. Click the " Write Params " box on the right.
3. Configure your flight controller as needed for your plane. Full flight controller setup is more than we can possibly cover here. Some controllers will have different telemetry ports, etc. If you need help with this you can post questions in our support forum.
