The Kramer DK42HU-3 lets one operator share a keyboard, mouse and supported display connections across 4 computers. Dual-head operation supports a two-display workstation.
DK42HU-3 Detailed Features
- Operate 4 computers from one console. A shared keyboard and mouse reduce the need for a separate peripheral set at every computer. This suits an operator who regularly moves between 4 systems at one workstation.
- Share a two-monitor desktop. Dual-head operation provides two display connections for the selected computer. This gives users space for two applications or a wider desktop, subject to the computer and display configuration.
- Work with detailed Ultra HD content. The model supports video up to 3840 × 2160 at 30Hz. Select a supported source format and compatible displays and cables to achieve the intended resolution and refresh rate.
- Connect HDMI video. The model's HDMI video connections determine the source and display cabling needed. Check the exact connector arrangement before ordering cables for all computer channels.
- Keep connected computers isolated. Security-focused signal paths and peripheral handling help reduce opportunities for information to cross between connected hosts. This supports workstations where separate computing environments must share operator equipment.
- Choose a shared-display or separate-display workflow. Supported KVM and KM configurations allow a shared display arrangement or keyboard/mouse sharing with computers connected to their own screens. Follow the model instructions when configuring the desired mode.
- Check keyboard lock status at the switch. Front-panel indicators show keyboard lock states such as Caps Lock and Num Lock. This helps the operator confirm the intended typing mode when using the secure peripheral arrangement.
- Authorize supported USB devices. The filtered USB interface supports controlled sharing of appropriate peripherals, including supported authentication devices. Device identification and authorization rules should be configured for the deployment rather than assuming any USB device will work.
- Follow the secure installation requirements. Use the prescribed peripherals and setup procedure, including the required monitor initialization. These requirements are part of the device design and should be checked before replacing attached equipment.
