Indicator LED details

The color and action of the indicator LED depends on whether you are connected by USB 3.0 or USB 2.0. For maximum performance, always use a USB 3.0 port and the included USB 3.0 cable. Note that frame capture rate will be reduced when connected via USB 2.0.

From the operating system's UVC drivers, the application will receive the AV.io SDI+ supported color space, resolution and frame rates.
