4. Remote Unit Configuration &
Operation
Cat5/5e cables are specifically designed for networking applications and not for transmitting
analog video. Your CATx KVM extender includes, and requires, advanced technology to
enable its use at high screen resolutions. This section describes how to optimize the video
signal, configure the Extender system and operate the Remote Unit.
4.1 Video Configuration Overview
To get the best out of your extender system it is essential that you configure it correctly and
tune the video signal. Tuning is necessary because of distortions that occur in a video signal
when it is transmitted over lengthy CAT5/5e cables. Generally, you only need to carry out
this procedure after installation.
When you have installed your extender system, run an application that requires a high screen
resolution. Examine the video image on the remote console’s monitor. You may see some of
the following distortion effects:
Smearing Loss of Sharpness
Black smearing at the
right edge of large
horizontal objects such
as title bars.
Blurring and lack
of detail, edges
appearing too
bright and sharp.
Color Separation or Skew
Brightness
Displacement of
individual colors
(caused by timing
differences in RGB
signal reception).
Image appears
brighter or darker
than the original.
The Remote Unit’s Focus control allows you to correct smearing and loss of sharpness
effects. The Brightness control adjusts video image brightness.
