KONA LHe Plus Installation & Operation Guide — Using Multiple AJA Products
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, 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 a third-party application 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 3G as the targeted product in the AJA Control Panel application.
Launch your third-party editing application. The application is now using the KONA 3G for
its input/output. Go back to the AJA Control Panel application and select a KONA LHe Plus
as the “targeted” product. Launch the AJA TV application. AJA TV would now use the LHe
Plus for its output. If you switch back to the third-party application, you would note that it is
still uses 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. 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.
