BRIEF INTRODUCTION
The KVM Switch allows you to control several sets of personal computers by a keyboard, a mouse
and a monitor. In the meantime, you just need to connect the cable and turn on the power to
control up to 256 sets of personal computers without installing any additional interface card or
software.
Easy Installation
The 3-in-1 CPU Connector (VGA, Keyboard and Mouse) can save the installation time and space
and assure the correct signals. The universal AC power input of 100~240VAC, 50Hz~60Hz saves
you the trouble of finding the space for installing the Power Adaptor. You can install a cascade to
facilitate expansions or transportation without requiring a cascade cable or changing the KVM
configurations.
On-Screen Display (OSD) Menu
The embedded OSD control module lets you name the PC and KVM and modify the KVM
configuration, and the security mode can prevent others from turning on the KVM by mistake and
switching the linked PC from the OSD. Most conveniently, the OSD not only supports keyboard
operations, but also supports mouse clicking.
Enhanced Video Quality
The special video circuit design supports resolution up to 1024×768, 75Hz, and also keeps the
same quality under the Cascade architecture.
