KONA LHi Installation and Operation Manual — Using Multiple AJA
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 Kona3-0, 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). 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.
When you launch an application such as Final Cut Pro, or AJA TV, that application will use the
product that is currently selected in the AJA Control Panel application for its input/output. Once
an application is running, you can change the "targeted" product selection in the AJA Control
Panel and select a different product. 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: select a KONA 3 as the targeted product in the AJA Control Panel application. Launch
Final Cut Pro. Final Cut Pro is now using the KONA 3 for its input/output. Go back to the AJA
Control Panel application and select a KONA LHi as the "targeted" product. Launch the AJA
TV application. AJA TV would now use the LHi for its output. If you switch back to Final Cut
Pro, you would note that it is still uses the KONA 3 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. You can even feed the output from one AJA product to another AJA product
on the same system in such cases.
AJA TV Preferences, Continue Playback when AJA TV is in background
AJA TV optionally supports playback in the background; checkbox “Continue Playback when
AJA TV is in background.
Notes on using
multiple AJA
Products:
Performance of multi-product use depends on a variety of factors: CPU usage, RAM, disk IOPS/
bandwidth for streams of video, etc. and therefore performance may vary. Also be aware that
multiple input/output streams are only supported by software that is explicitly designed for a
multi-product environment.
