KONA v10.5 www.aja.com 80
Using Multiple AJA Products
Starting with the v7.5 drivers, more than one AJA product can be used with your host
computer. Using the AJA Control Panel application, you can choose which installed
product an application uses for input/output. In the upper left corner of the AJA Control
Panel application, you will see a board name, such as KONA 3G-0 and the pane heading
will read “AJA Control Panel” if you have more than one product and the associated
drivers installed (if only one product is installed, you’ll see no product or pulldown and
the product name will appear in the header). To “target” a specific installed product for
use, click on the text in the upper left hand side of the UI and select from the list of
available products that appear in the pulldown.
Figure 77. Control Panel Screen Showing Multiple AJA Devices
When you launch an application, or AJA TV, the application will use the product that is
currently selected in the AJA Control Panel for its input/output. When an application is
running, you can change the “targeted” product selection using the Control Panel
pulldown menu. The running application will retain its connection to the product. If you
change the “targeted” product and launch a different application, that application will
use the new product for its input/ output, while the first application you launched will
continue to use the other AJA product.
Example: if you select a KONA card as the targeted product in the AJA Control Panel
application and launch an Adobe video editing application, that application is now using
the KONA card for its input/output. Go back to the AJA Control Panel application and
select an Io Express as the “targeted” product. Launch the AJA TV application. AJA TV will
now use the Io Express for its output. If you switch back to the Adobe application, you
will see that it is still using the KONA 3G for its input/output. Note that some applications,
like AJA TV, have a provision for playing in the background, so playback on one product
could even continue when switching the targeted device for use with another
application. In such cases, you can even feed the output from one AJA product to
another AJA product on the same system.
