Io XT Installation and Operation Manual — AJA Control Panel Overview
Info: displays status information and firmware version # of the Io XT and how it is
installed in the host Macintosh. This information is generally intended for
troubleshooting/support.
Block Diagram Screen – the top area of the AJA Control Panel shows a visual picture
representing the processing (if any) that's currently occurring, including inputs/
outputs, any up/down/cross conversion, reference source, and system status. Lines
between inputs, the framebuffer, and outputs, show a video path. Where there are
no lines, it shows there is no connection; this can be either because an input or
output isn't selected or because no video is present at the selected input. The lines
will also show whether the input or outputs are single inputs/outputs, video or
video + key.
Icon objects on the block diagram screen (input/output icons, frame buffer, etc.-
also called “widgets”-indicate their status by color (explained later) and can be
clicked for context-sensitive information and choices. (These same choices can also
be made from the tabbed Control panel screens.)
Note: You can use the Up/Down arrows on your keyboard to navigate Tab selections
Color Meanings—all items in the AJA Control Panel block diagram are color-coded to
show what is happening in realtime. This applies to both icons and text. These
colors have the following corresponding meanings:
Blue: video is same format as the Primary Format (framebuffer)
Red: the selected operation cannot be performed or an invalid selection has been
made
Yellow: reference video (black burst or other reference source)
Green: indicates that the Io XT is performing some kind of active change to the
video, to make it different from the Primary Format (e.g., up/down convert, format
change, etc.).
