Hi friends. I am glad to present a new alpha-version of the firmware with built-in OSD support (only MAVLINK protocol supported, but we are working around UAVTalk protocol).
To connect the BlackBird 2 to the flight controller, you need to use a full cable (see manual, paragraph 1.3). Full cable allows you to use all the contacts of the interface connector BlackBird 2. To use the full cable you will need a soldering iron.
To connect the BlackBird 2 to the flight controller, connect the GND camera (pin 2) to the GND flight controller. Connect MAVLINK_RX (3 pin) to the TX flight controller. To connect to the video transmitter to use the GND(pin 7) and 2D/3D video output (9 pin). To connect to the battery used GND (pin 5) and VCC (6 pin).
When you update the firmware on the camera, there will be a 7 item menu - setting convergence OSD.
P.S. Before you connect the BlackBird 2 to a PC to update the firmware, read the USER MANUAL
If after updating the firmware on the camera no glow LEDs , not to worry, start the flashing process again.
