CHAPTER 2: KV4402A
2.1 INTRODUCTION
KV4402A is a dedicated multi-platform KVM switch capable of managing up to two different computers through
four DisplayPort™ monitors, one USB keyboard and mouse, a single set of speakers, and a USB 2.0 Device.
The USB emulation technology utilized by the device enables immediate hotkey source switching through a remote
USB keyboard and mouse. It delivers high resolutions of up to 4K (3840x2160 @ 60Hz) with zero pixel loss from
TMDS signal correction.
•
Source switching made easy: KV4402A provides a simplified management approach to up two computers with
DisplayPort, stereo audio, and USB 2.0 outputs. This dynamic KVM console can be controlled remotely from
easily accessible keyboard hotkeys or RS-232 commands, as well as directly through the console’s easy-to-read
front panel.
•
EDID learning and programming: Detection of DDC signals for all attached devices is effortless with the
KV4402A due to its real EDID learning and programming. This is vital in optimizing the resolution of the
selected graphics card to properly display on the remote monitor.
•
Full USB keyboard and mouse emulation: The USB keyboard and mouse emulation utilized by the KV4402A
provides accurate and quick source switching by means of keyboard hotkeys and mouse actions. It imitates
the presence of a keyboard and mouse for every attached computer through a USB cable. This is essential as it
simulates the existence of the keyboard and mouse to all the computers while switching without interruptions.
