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.
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 USB2.0:
Blue LED means USB 3.0 Green LED means USB 2.0
