KL1508Ai / KL1516Ai User Manual
Problem
When I emulate the Sun keyboard, I
can't go into OK Mode ([Stop] [A]).
There are ghost images on the
external monitor.
I can't set the computers' screen
resolutions higher than 1280 x 1024,
even though the KL1508Ai / KL1516Ai
supports 1600 x 1200 for remote
computers.
When I switch to one of the computers
on my installation, the LCD monitor
screen goes blank. All I see is a black
screen.

Resolution
To go into OK Mode, use the following key
sequence:
1. Press and release [Ctrl].
2. Press and hold [T].
3. Press and hold [A].
4. Release [T] and [A] together.
The distance between the external console
and the KL1508Ai / KL1516Ai is too great. The
maximum VGA cable distance should not
exceed 20m and, in some cases, may need to
be shorter. Replace the VGA cable with one of
an appropriately short length.
The maximum screen resolution of the
KL1508Ai / KL1516Ai's integrated LCD monitor
is 1280 x 1024. In order to protect it from being
damaged by resolutions that are beyond its
display capability, we recommend that the
screen resolutions of the connected computers
be set to 1280 x 1024 or lower.
If you wish to set the screen resolutions of the
connected computers to something higher
than 1280 x 1024, see Screen Resolutions
Higher than 1280 x 1024, page 204.
The maximum screen resolution of the
KL1508Ai / KL1516Ai's integrated LCD monitor
is 1280 x 1024. The screen resolution of the
problem computer is set to something that is
too high for the KL1508Ai / KL1516Ai's LCD
monitor to display.
To resolve the problem, connect an external
KVM console (with a monitor capable of
displaying the problem computer's screen
resolution) to the KL1508Ai / KL1516Ai's
external console ports. Use the external
console to access the problem computer and
reduce its resolution to 1280 x 1024.
Note: Although the LCD monitor only supports
video resolutions of up to 1280 x 1024, the
KL1508Ai / KL1516Ai, itself can support video
resolutions up to 1600 x 1200 @ 60 Hz. If you
wish to set the screen resolutions of the
connected computers to something higher
than 1280 x 1024, see Screen Resolutions
Higher than 1280 x 1024, page 204 for details.
