5.5.3.2.4 Setting the Delay
An important aspect for the use of the CATCenter system is that the delay of
signals on the various wire pairs of a CAT-x cable must be the same. Different
delay times lead to color errors that appear similar to a convergence error on
the monitor. The severity of the color error depends on the cable length, cable
type, screen resolution, and screen refresh rate.
The cause for this type of delay difference is the uneven transposition of the
various wire pairs.
A visible effect of the delay differences is that the three colors red, green, and
blue do not converge on top of each other. The text on the monitor then
appears as follows (exaggerated for clarity):
Vor der Kompensierung
der Laufzeitunterschiede
Nach der Kompensierung
der Laufzeitunterschiede
The three colors appear next to each other. The display on the monitor does
not have well-defined edges. It appears blurry and may have a colored aura.
The CATCenter system automatically compensates for delay differences. A
manual setting is also possible. This manual setting is established using either
the UCON or the UCON-s.
However, this will only be required in exceptional cases.
This setting is not necessary and thus not available for UCON-a and UCON-IP.

The delay compensation can be set in the CATCenter system for all three color
signals up to 46 ns.
At 0 ns, no delay compensation (delay) has been set.
The following keys are available to you to modify the delay compensation:
