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 UVCdrivers, the application will receive the AV.io SDI supported color space,

resolution and frame rates. If you’re not sure if your controller is USB 3.0 or USB 2.0, plug AV.io SDI into the

capture computer and look at the indicator LED. After initial boot up (red LED), blue is used for USB 3.0 and

green is used for USB 2.0:

Blue LED means USB 3.0 Green LED means USB 2.0
