2. Overview
2.1 Introduction
A KVM Extender is used, to extend the distance between a CPU and its Keyboard / Monitor /
Mouse considerably. The allowed distance is limited by the physics and the make of the
cables.
If the total distance expires the allowed distance, Repeater may double the total allowed
distance.
In some environments, the signal path may be inhomogeneous. This means, a part might be
based on CATx, another part in Multimode. The Cross- Repeater hereby allow to convert
from one medium to another, without laborious regaining the original signals and resending
them.
The Repeater/Cross- Repeater described in this manual are especially designed for the DVXi
KVM Extender Family. Operation with other products is not possible.
