Control Panel Operation
Control Tab Screen
The Io XT can be controlled by various software applications running on a host Mac.
The Control Tab is where you select how the Io XT directs video and is used by
application software. This screen also provides control for configuring output timing
with regard to external reference video and horizontal/vertical delay.
At the top of the Control screen it will show the current Default Output and the
application currently controlling the Io XT.

Default Video Output—this is where you select what Io XT will output as a default
when no application has control of the board, such as when the Finder is active. Since
Io XT can be controlled by software applications as well as its own control panel, the
output can change dynamically. When you select many video applications, they will
grab control of the Io XT inputs/outputs. These settings determine what happens
when an application that doesn't grab the Io XT inputs/outputs is active.
Default Output Choices and their meanings:
Black: this selection directs Io XT to output video black whenever an
application isn't controlling the card.
