What is KVM Switch?
KVM switch is short for keyboard, video, mouse switch, a hardware device that enables a single keyboard, video monitor and mouse to control more than one computer one at a time.
KVM switches are popular among users who have upgraded their home PC systems and want to still use their old computers but do not want to invest in a second keyboard, monitor and mouse. KVM switches are also used by business to save money when one person uses more than one computer and in server farms where it is only necessary to periodically access each separate server in the farm one at a time.

A typical KVM Switch has appropriate number of KVM inputs (2, 4, 8, 12, 16) for connecting the mice, keyboards and videocards of the machines, and single input for the keyboard, mouse and monitor used as a console.
KVM devices are highly varied - some offer keyboard and mouse emulation, which means that all the connected computers can be booted simultaneously (in case of power failure for example).
The switching takes place manually (with keys on the switch) or automatically (with keyboard shortcuts or on time intervals - which is extremely useful with security systems consisting of multiple computers)
Some KVM Switches has OSD menus for control and status and RackMount casings.
Other support daisy chaining which means that many switches can be connected one after another thus increasing the number of computers which can be managed from a single console.

What is KVM Extender?
The KVM Extender system consist of two devices - transmitter and receiver allowing for operating a single computer system remotely - trough the existing networking cable. The maximum operating distance may vary depending on the cable type - it is approx. 110 meters with standard Cat. 5 cables.
The Receiver unit is connected to the computer with cables for video, keyboard and mouse and to the receiver unit trough the network cable. The receiver on other hand, has connectors for the Monitor, Keyboard and Mouse which control the remote computer.

What is Video Splitter?
The Video Splitter (also called Video Distributor) is a device that allows the video output from one computer to be displayed simultaneously on multiple VGA monitors - 2, 4, 8, 16... It is a useful solution for presentations and surveillance applications.

Cascading and Daisy Chaining?
There are two methods of expanding your KVM switch installation by adding additional KVM switches and thereby greatly increasing its overall capacity; cascading and daisy chaining.

I. Cascading


Cascading KVM switches is a method of adding capacity to a KVM installation. It involves using a CPU port of the Parent KVM switch (one that is above a switch linked down from it) and connecting to a Child KVM switch. With numerous Child switches linked down from the Parent, the effect is reminiscent of the way water cascades down over a waterfall. Cascading can significantly increase the number of computers on an installation, however the Parent switch loses one CPU port for each cascaded KVM switch that is added.

II. Daisy Chaining


Daisy chaining is another method of expanding the capacity of a KVM switch installation. In a simple daisy chained installation, KVM switches are strung together in a chain similar to the way children make chains of daisies by tying the head of one daisy to the end of another. The first daisy chained KVM switch is called the Master unit and each subsequent unit on the chain is referred to as a slave. In a typical daisy chained installation, the total number of consoles is increased as the number of units daisy chained increases. The console that belongs to the Master KVM unit can also access and control all of the computers down the daisy chain installation. Daisy chaining preserves CPU ports by using Chain In and Chain Out ports to attach each daisy chained KVM switch.
