DP1.2-MUX3-ATC - The KVM switch with Instant switching technology and native 4K UltraHD support

The KVM switch DP1.2-MUX3-ATC is designed for working environments requiring instant switching and native 4K UltraHD resolutions and enables you to operate up to three computers via one console.

The console is provided with a keyboard, a mouse and a DisplayPort™ monitor. The computers connected to the KVM switch are operated from the installed console.

Instant switching technology

Thanks to the newly developed instant switching technology the switching process between computers is done in real time and takes place either via the push buttons on the front panel, configurable key combinations, or a serial device which is connected to the Service- or RS232 port.

Error free operation of connected computers guaranteed

The front panel of the device provides two USB 3.0 interfaces to operate any USB devices. The connected USB devices are available to whichever active computer.

The KVM switch emulates keyboard and mouse on each channel and hence guarantees error-free booting at all times.
