DPN-4DUO-S: 4-port dual-video DisplayPort KVM switch 

with USB 2.0 peripheral sharing and full USB KVM emulation 

DPN-4Duo is a dedicated multi-platform KVM switch capable of managing four dual-video computers through two DisplayPort monitors, one USB keyboard, one USB mouse, and other USB 2.0 devices. The dual-head compatibility of the switch enables increased workflow capabilities.

DisplayPort is one of the latest options in screen connectivity that delivers top quality high-definition video, and this device is DisplayPort 1.2 compliant with support for screen resolutions up to 3840x2160 @ 30Hz. HDMI and DVI video connections are supported with the proper video adapters, and the device is backwards compatible with prior DisplayPort versions.

The USB emulation technology utilized by DPN-4Duo enables immediate hot key source switching through the connected USB keyboard and mouse. Additional USB peripherals can be attached, like a USB printer. RS-232 control and front panel switching are supported.

Source Switching Made Easy
DPN-4Duo provides a simplified management approach for four DisplayPort equipped computers with USB 2.0 outputs for a keyboard, mouse and other USB peripheral devices. This dynamic KVM console can be controlled by keyboard hot keys or RS-232 commands, as well as directly through the console's easy-to-read front panel.

EDID Pass-Through
DPN-4Duo features EDID pass-through technology which enables smooth and efficient switching, making the device easy to implement in virtually any scenario. This plug-and-play EDID functionality makes set up hassle free and simple.

Full USB Keyboard and Mouse Emulation
The USB keyboard and mouse emulation utilized by DPN-4Duo provides quick source switching via keyboard hot keys. DPN-4Duo simulates 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 in order to switch without interruptions.

Flexible Control and Sharing
• RS-232: Any external device or program supporting RS-232 can control DPN-4Duo. DPN-4Duo uses a very simple protocol that enables easy integration with other devices.
• USB/Keyboard: Hot keys allow the user to switch and control all the different functions of the KVM switch.
• Independent Simultaneous Device Selection: Flexibility is key with DPN-4Duo. It enables the use of a USB keyboard and mouse of one computer while other USB peripherals such as scanners and printers are connected to other computer sources. DPN-4Duo maintains the ability to switch all connected devices to any one of the computer sources as with any other KVM switches.

Real-World Applications
DPN-4Duo has a broad range of applications, but the main function is to centralize the access of up to four dual-head computers that support DisplayPort displays in a single console. Not only does it function as a KVM console, but it also supports USB 2.0 functionality. This allows users to access nearly any USB device, including those not supported by other KVM switches. DPN-4Duo is the ideal solution for medical, industrial, studio and defense applications, where it is not practical or safe to have multiple CPUs in the vicinity of the console.
