When you need to control several servers or computers at the same time, you can't do without a KVM switch. It is this device that allows you to access the control of several pieces of equipment from a single workstation - monitor, mouse, keyboard. Modern KVMs also control the transmission of video and audio signals. After choosing the right swatch, you need to buy a used cable for KVM switches - the quality of system control and data transmission parameters depend on its characteristics.
Characteristics of KVM switch cables
There are different ways to connect equipment to a switch. The most difficult is to lay separate wires for each control device. A special cable integrates wires for transmitting different types of signals. The design feature is a shielded wire with a ferrite core that reduces interference. The ends of the cable are equipped with plugs for the corresponding ports. The cable for the KVM console looks the same, the only difference is in the types of connectors.
To use a KVM switch, several types of signals need to be transmitted, so the cables are divided into 2 or 4-in-one. The most popular ports:
- USB - for connecting controls and audio signals;
- VGA - for analog video signal transmission;
- HDMI - for digital video and audio transmission;
- DVI-I / DVI-D - for digital data packets.
PS/2 ports used to be common, but are now considered obsolete.
When choosing a cable for the D-Link DKVM-CB5 KVM, you should consider the types of ports on your equipment and choose the appropriate cable or adapter.
In addition to connectors, Aten KVM cables may differ in length. The minimum length is 0.6 m, suitable for compact workstations. The maximum length is up to 70 m. It's better to choose a used cable for Aten KVM switches designed for server systems or large offices with a length margin.
