The switch card plays an important role in a KVM matrix (keyboard, video, mouse). It is there to coordinate the switching logic between the various input and output devices.
This special hardware component acts as a kind of "brain" of the matrix. The switch card is what makes the dynamic connection between computers, servers, keyboards, mice and monitors possible in the first place. It is normally an external component that is installed in a card slot on the matrix hardware.
Within the KVM matrix, the switch card monitors signal distribution and forwarding. It processes the signals that are input from keyboards, mice and other devices. It then transmits these to the corresponding computer or server. At the same time, the card monitors the video output by forwarding graphics signals from the computers to the corresponding monitors.
The ability to adjust connections in real time is a major advantage of a switch card in a KVM matrix. This means that users can easily switch from one computer module (CPU) to another.
Modern switch components can even integrate multiple switch cards into a larger matrix topography. This creates additional functions such as the management of user authorizations or the scalability of the entire network. Network management systems can also be added to the system more easily.
The best way to talk about complex topics is in person. Via chat, e-mail, phone or in a personal demo remote or on-site.
