Four-Port DVI KVM Switch

The Avocent SC640-001 is a new KVM switch that lets one operator control four computers from a single DVI monitor, keyboard and mouse. It supports dual-link DVI-I video up to 2560 x 1600 resolution across four PC connections. The unit includes six USB ports and five DVI ports for flexible peripheral and display wiring.

Suited For Single-Operator Multi-System Desks

This switch suits administrators, developers or test engineers who need instant access to four tower or rack systems without extra monitors. It is not for buyers who require more than four computer ports, who need DisplayPort or HDMI native inputs, or who want multi-user concurrent access to the same targets.

Four Systems At 2560 x 1600

The switch comfortably handles four connected computers at the maximum stated resolution of 2560 x 1600 over dual-link DVI. Headroom ends at the fourth port; a fifth system cannot be added. The 100 V AC to 240 V AC power input covers global mains voltages without external adapters.

Questions about this item

Do my four computers each need a DVI-I dual-link output and a USB port to connect to the SC640-001?

Yes, each of the four computer ports on the SC640-001 requires a DVI-I dual-link video connection and a USB link from the host system.

Can I keep using my existing DVI-I dual-link monitor that runs at 2560 x 1600 with this switch?

The console video port is a DVI-I dual-link female connector supporting up to 2560 x 1600, so your current monitor will work at its native resolution.

How do I confirm the SC640-001 is switching video and USB correctly after I cable everything?

Press the front-panel port selectors; the active-port LED should change and the console monitor should instantly show the chosen computer's desktop while keyboard and mouse respond on that system.
