from microphone on the TX but also from that on the
RX at the same time.
This special feature will allow both admins on both
RX console and TX console to mix their sound input
to same application on the TX console, so that both
admins can communicate with the same third-party
counterpart.
However, if you want to shut off the sound input from
the RX and use only that from the TX, you can just
configure the RX console to be OFF (Deny Access),
so that you won’t have mixed sound input coming
from the RX console microphone.
Optimize the Video Display on the Remote
Console
To achieve an optimized display output on the
remote console (i.e. the Receiver) you will need to
adjust the various video parameters such as
Brightness and Sharpness in an optimized
combination that gives you the best video display.
Please follow the procedure below to achieve an
optimized display output on your remote console
screen (on RX unit):
Step 1. Choose a video display content that you
think will be suitable to serve as a reference for the
visual adjustment. You can choose a document that
integrates texts and graphics so that you can use it
as a reference to achieve an optimized video display
for either textual or graphical content on the Receiver
video output. One alternative can be the visual
testing program provided by the display card vendor.
Step 2. Adjust the Brightness and Sharpness - First,
invoke the OSD menu by hitting the hotkey, SCROLL
+ SCROLL + Space, then go to the Video Setting
submenu.
Next, adjust your video display for an optimized
output. The Brightness adjustment can help you to
tune the picture luminance as a whole to lighter or
darker output that best suits your visual perception.
The Sharpness is the edge contrast that you will
perceive.
Adjust the Brightness: The brighter the
picture, the more luminance will be added to
the picture as a whole.
Adjust the Sharpness: To add more
sharpness to the picture is to help you
distinguish more detail out of the edges of a
line or shape.
When you have adjusted the Brightness and
Sharpness to achieve your desired level, you can
then move on to adjusting the Red Delay and Green
Delay to achieve your optimized video output.
Step 3. Adjust the Red Delay and Green Delay: the
Red, Green and Blue are the primary colors that
constitute our color perception scheme on the
monitor.
The CAT5 extender uses different wires in the UTP
cable to carry the signals of different primary colors.
The different wires in the twisted-paired cable are all
slightly different overall lengths and the longer the
CATx cable, the greater the difference in length
between wires.
This difference in length causes the red, green and
blue colours to become out of sync. You will need to
adjust the delay time for certain colour signals on
certain wires to make the three colour signals arrive
into the display in good sync.
The CAT5 KVM Extender requires you to manually
adjust only the Red delay and the Green delay - the
Blue delay is automatically tuned and optimized by
the machine according to the other concurrent video
parameters.
The values of the Red delay and the Green delay will
be limited within a preset difference range. This
means, whenever you try to adjust either the value of
the Red delay or the Green delay to be outside of
the allowable preset difference range as compared
to the value of the other colour delay, the other
colour delay will be automatically adjusted to be
within the difference range to prevent the video from
being perceptibly disoriented.
With the Blue delay automatically tuned in relation to
the other colours and the Red and Green delays
limited within a comfortable difference range, the SL-
KXSA-300 CAT5 KVM extender facilitates an easier
and more intuitive way for video optimization.
No Video Troubleshooting
Q. When I connect a monitor to the CAT5 KVM
extender, it does not display any video.
A. If you encounter no video or other display
problems with a specific monitor, you should try to
copy the EDID information from the smaller monitor
among the local monitor and the remote monitor to
see if this can eliminate the display problem.
