Overview

The KFH251S 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@30Hz. 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 KFH251S matrix extender is a perfect combination of high-quality image and low latency (<16ms). 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.

Flexible and Further Connection

The IP KVM extender support resolutions up to 4K@30Hz with low latency over standard 1 GbE networks. Featuring HDMI connector, the KFH251S delivers FHD video, keyboard, mouse, USB 2.0, audio, and RS232 signals with a single pair of KVM transmitter and receiver units—over LAN, WAN, or internet—up to 120m through CATx cable, 20km through fiber optic. It helps operators stay away from computers or other devices and create a minimalist office environment.

Flexible Connections and Configuration

Kinan KFH251S IP KVM extenders can be deployed as point-to-point connections or as KVM over IP matrix over a LAN with no distance limitation, offering flexible connections to adapt different installations. It can connect multiple signal sources (such as servers, workstations, cameras, and video walls). The matrix system has flexible expansion capabilities, supports long-distance one-to-one, one-to-many, many-to-one, and many-to-many installations, and realizes the deployment and interconnection of multiple control centers across floors, buildings, and regions.

Collaborative Shared Connections (Push & Get)

Operators could push their monitor’s content to the video wall or other operator’s monitor, they can also get the monitor’s content from the video wall or other other operator’s monitor, which allows users to maximize collaboration and improve teamwork

Matrix Centrally Management Unit

The Kinan matrix manager unit is an easy-to-use hardware to configure, manage, and monitor all transmitter and receiver units. With an intuitive interface, you can configure user access rights and get a real-time overview of system connections and users through the manager unit. It’s easy to set up the manager unit, no software is needed, just connect it with a keyboard, mouse, and monitor will be OK.
