Frequently Asked Questions

Our general FAQs will answer your questions if you’re new to the world of KVM.

What is KVM?

KVM is short for Keyboard, Video, and Mouse and refers to computer ports. KVM products are connected to these and other ports, from where they extend or switch computer signals.

Hence, KVM is the group designation of a technology, and not a special brand or company.

Our KVM solutions

What is a KVM switch?

A KVM switch connects many computers that can be operated over one console (monitor, keyboard, mouse).

Switching between computers is carried out over a button at the switch or via hotkey. Depending on size, KVM switches also provide an OSD to switch between computers.

What is a KVM extender

An extender system consists of a transmitter and a receiver. The transmitter is connected to the computer’s keyboard, video, and mouse interfaces, while the transmitter is connected at the remote console. Both devices are connected with one or more cables.
