Are you connected to the correct input of your Blackmagic device?
Generally, Blackmagic Design doesn't specifically mark the input/outputs of the device on the actual hardware. Please check your capture device's documentation to confirm the proper input.
Is your camera configured properly?
Many cameras with multiple output formats allow you to define your specific output method. Check your camera's settings to confirm your are properly configured for HD-SDI, HDMI or analog, depending on your input to the Blackmagic Design device.
Does your camera output to an external display?
Connect the camera's output to an external display such as a monitor to verify the video signal. If you do not receive a signal, try a new wire of the same type or double-check your camera's settings.
If all of the above fail please contact Livestream Phone Support using the instructions found on the support.txt file on your USB dongle.
