ATEN CS1798A 8-Port 4K HDMI USB KVM Switch

Consolidate console access to eight HDMI-equipped computers through one USB keyboard, USB mouse, HDMI display, speakers, and microphone. The ATEN CS1798A provides single-display 4K video output and USB 2.0 peripheral sharing for environments where administrators need direct local control of multiple servers, workstations, test systems, or security appliances. Switch computers from front-panel pushbuttons, keyboard hotkeys, or the included infrared remote-control capability. Independent KVM and USB focus switching lets an attached USB 2.0 peripheral remain connected to one host while the console display and input devices are working with another. HDMI audio support carries speaker and microphone connections through the switch rather than requiring a separate analog audio selector. The 8-port format reduces the rack space and cabling associated with individual console connections while retaining direct access to each connected computer. Cascade support extends the number of manageable systems where a larger local KVM topology is required. This model fits mixed operating-system environments and supports standard USB keyboard and mouse control from a shared console. Use it where HDMI source systems require 4K display output and an operator needs fast, physical access without a network-dependent management session.
