OPERATIONAL HIGHLIGHTS
Save valuable desk space
Allow users that work in spacerestricted environments
to interact with multiple
computers in spite of having
limited desk space.
Reduce costs
Use a single set of peripherals
with multiple computers.
Obviate the need for purchasing
and installing dedicated, percomputer peripheral sets.
Smoothly switch
between computers
(Virtual Display
Technology)
Automatically switch control from one
computer to another by dragging the
mouse cursor over the computer’s display
border. Peripherals switch to the next
computer without having to press any
buttons once the mouse is passing the
display border.
Keep up with future
requirements through
interchangeable KVM /
KM functionality
Adjust with versatile setup scenarios. The
device can be congured in two modes, KVM
and KM. In KVM mode (default) one display,
keyboard and mouse set is shared between
all computers. In KM mode, each computer
is connected to a separate display while
keyboard and mouse are shared, thus allowing
simultaneous work on multiple computers.
