Exclusive Use
Settings: ALLOWED, DISABLED
In normal operation, the AdderView Matrix will allow two or more users to
share access to a computer. In this mode, the computer’s video picture will be
displayed on all the user’s monitors but only one user may have active control
of the computer’s keyboard and mouse at any one time. The AdderView Matrix
detects an active user by looking for keyboard and mouse data.
A user becomes inactive if no keyboard or mouse data has been received by
the AdderView Matrix for a specied timeout period. Whilst one user is active
all the other users that are connected to the same computer will see a “video
only” message displayed on their screen. There may be situations where
particular users want to be able to control and view their computers in private
with exclusive use. The AdderView Matrix has the facility to allow users to select
exclusive use of computers but this facility should be used with care. When
exclusive use is requested the video from the selected computer is only available
to the user with exclusive access.
Users that have selected exclusive access are never timed out by the AdderView
Matrix and so all other users are effectively “locked out” until the exclusive user
switches to another computer or logs out. This could potentially be very irritating
if a user has selected exclusive use and has then left their desk without logging
out. This would prevent other users from working on the computer until they
came back. Consequently the system administrator can disable all exclusive use
so that all connections are shared.
Automatic Logout
Settings: DISABLED, ENABLED
The AdderView Matrix enables you to restrict access to your computers on a
login basis. If a user forgets to logout when they have nished accessing the
AdderView Matrix then the user console may unintentionally be left with full
access to all the computers. The AdderView Matrix may be set to automatically
logout unattended user consoles when the screen saver kicks in. This reduces
the risk of security problems by preventing user consoles remaining in a
permanent “logged-in” state when there is no keyboard or mouse activity. The
automatic logout feature is only enabled when the screen saver feature is active
(i.e. not disabled).
Global Preferences
Global preferences are available only to the Admin user and allow settings to be
made that affect all users attached to the AdderView Matrix.

Mouse Switching
Settings: ENABLED, DISABLED
Like most Adder Technology KVM switches, the AdderView Matrix’s channel
may be switched using a three button mouse or IntelliMouse. Pressing the
central button or wheel button together with the left hand mouse button will
cause the AdderView Matrix to switch to the next available computer. When
mouse switching is enabled the central mouse button or wheel mouse button is
allocated to control the AdderView Matrix and is not therefore available for use
by computer applications. If you want to use the central mouse button within
your applications you will need to disable mouse switching. The rotation action
of an IntelliMouse wheel is not affected and is always available to the computer
application.
