Before we go into too
m
uch detail, here are so
m
e basic definitions you should know (please
refer to the figure that follows for reference). After studying the basics, read “
Who is
Controlling KONA
?” later in this chapter for
m
ore advanced infor
m
ation on how applications
interact with the KONA LHe Plus board.
Control Panel Screens
—the botto
m
area of the AJA Control Panel provides different
infor
m

m
the left
navigation colu
m
n will result in an infor
m
ation screen corresponding to that screen’s
topic. Each of the Control Panel screens are described on the following pages.
Screens available are:

enables installation of AJA card fir
m
ware.
Info
:
displays status infor
m
ation about the KONA. This infor
m
ation is generally
intended for troubleshooting and 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 down-conversion, reference source, and syste
m
status. Lines between
inputs, the fra
m
ebuffer, 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.
Icon objects on the block diagra
m
screen (input/output icons, fra
m
e buffer, etc.-also
called “widgets”-indicate their status by color (explained later) and when clicked will
bring up the proper Control Panel screen used to configure that ite
m
. For exa
m
ple,
clicking on an SDI output icon will cause the “SDI Output” screen to be displayed below
the block diagra
m
. With the
m
ouse on a block diagra
m
ele
m
ent, you can also control
click to reveal contextual drop down
m
enus for certain functions.
Text Color
—Colored text in the block diagra
m
provides an indication of signal type and
what the KONA LHe Plus is doing. Text in blue shows the values auto
m
atically selected,
while text in black shows values that have been
m
anually selected. Text in red shows
that the KONA is not detecting a signal or cannot negotiate with the attached device
(even if it can’t detect an output device, it still shows the signal it is outputting).
