electronic KVM switch
A KVM switch which utilizes one or more microprocessors to communicate with the attached computer(s);
an active switch.
GUI
Abbreviation of Graphical User Interface – a program interface utilizing the computer’s graphics capabilities
(such as icons and drop-down menus) to make a program
easier to use, as opposed to utilizing only keyboard commands.
hot plugging
The ability to add and remove devices to a computer whiel the computer is running and have the operating
system automatically recognize the change.
NTI KVM switches that are described as hot pluggable allow the user to add and remove computers and/or
peripheral devices to the KVM switch without powering down the KVM switch. (NOTE: it is recommended
that computers being added or removed to the KVM switch be powered down.) Other attached computers do
not perceive any loss of keyboard or mouse, and thus are not disrupted by the change.
impedance matching
A measure utilized to ensure a high-quality signal over long distances of cable; the adjustment of impedances
so they equal each other, or the insertion of a suitable transformer between different impedances to
accomplish the same purpose.
infrared wireless remote
A method of controling a KVM switch from up to 50 feet away. The KVM switch is equipped with an
infrared signal receiver; the user then controls the KVM switch by utilizing a remote control with an infrared
signal transmitter.
keylock access
A method of limiting access to a KVM switch. Authorized users must possess a key, which must be inserted
and turned before the KVM switch will accept commands.
KVM switch
A keyboard-video-mouse switch device which allows multiple computers to be controlled from one or more
control stations.
LCD
Abbreviation of Liquid Crystal Display. A method of controlling a KVM switch in which the Liquid Crystal
Display provides feedback to keyboard or touch-button commands, such as the names assigned to the
attached computers, scan dwell time and port selection.
legacy
A term for computers not equipped with USB ports.
master switch
A term used in cascade applications. This refers to a KVM switch which has additional KVM switches
attached via the computer ports, thus expanding the total number of computers which can be controlled by
one keyboard, monitor and mouse. The master KVM switch can be a 4, 8, 16 or 32 port KVM switch. See the
section on Cascading for additional information.
