Ultra HD
Users that work with multiple computers such as,
nancial traders or command & control operators are
inconveniently forced to interact with multiple sets of
keyboard, video, mouse and audio peripherals.
KVM HIGHLIGHTS
Simplify user experience when
working with two computers
Copy & Paste
Transfer text and les between all the computers
that are connected to the KVM through the KVM
(no network connection is needed between
parties). Use standard copy and paste keyboard
key combinations (CTRL+C / CTRL+V) or mouse
context-menu commands to transfer data between
computers that are connected to the KVM.
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.
The Keyboard Video Mouse (KVM) switch offered by
HSL allows eortlessly sharing a single set of peripherals
between two computers.
Freeze Audio
Assign the audio port to a specific computer
while switching the keyboard, video and mouse
between other computers. Useful for scenarios
where a user has to listen to audio originating from
one computer while working on another computer.
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.
