Overview Of Hotkey Sequences

KVM Switches that do DVI from Aten
By

You can switch among clients by pushing buttons on the switchbox itself, or by entering hotkey sequences at the console keyboard. Striking the Scroll Lock key twice gets the KVM's attention, and additional keys allow individual client ports to be managed and selected directly. Hotkey sequences make it possible to route video, audio and USB signals separately through the KVM, and to access USB devices attached to KVM on a per-client basis. This can, however, sometimes lead to unexpected results. You could wind up watching video from client 1, listening to sound from client 2, yet be able to access USB devices attached to the KVM only on client 3. For an easy reset, simply push a button to switch all connections to the next KVM port in sequence. At that point, all prior settings are irrelevant and all point to the same client.

History Of The KVM Principle

The whole phenomenon started with a simple switchbox for printers. A user sitting next to the printer had to flip this switch by hand to select an input source, when someone else wanted to print. That way, it wasn't necessary to have two or three printers in an office. The idea remains a good one, only it works much more easily for networked devices (including printers). These days, in fact, you can save a lot more by using a switch box than just the cost of another printer.
