1. Introduction
The KFH286K IP KVM matrix extenders are highly optimized KVM extenders. The
point‐to‐point connection supports transmission distance of 120m, and resolution up to
3840×2160@60Hz. This series of extenders can be connected to an 1G network switch to
form a matrix switching system, which supports point‐to‐point (P2P) mode and matrix
(Matrix) mode. The matrix switching system composed of extenders supports up to 9999
nodes by using a centralized management software, and it can support up to 40 nodes
without using a centralized management software. It can connect multiple signal sources
(such as servers, workstations, cameras and video walls).
With the matrix switching system, computers and servers can be located in the central
server room far from the workstation to improve security, reduce the temperature and
noise of the working environment, and achieve a quiet and friendly human‐computer
interaction environment.
The video compression algorithm of KFH286K matrix extender is a perfect combination of
high‐quality image and low latency (<8ms). The USB and video signals are transmitted
through CAT5e/6/7 network cable.
It supports USB devices such as touch screen, USB sound card, printer, etc., it can also
support USB storage devices.
