Triple-Computer Dual-Monitor KVM Switch

The SMA KC-302AS lets one keyboard, mouse and four USB 3.0 peripherals control three desktops or laptops across two HDMI monitors. EDID emulation keeps window layouts intact when switching between locked or active systems. It operates driver-free on Windows, Mac, Linux and Unix platforms.

Passive Cooling With External 12 V Power

The unit draws power from the included DC 12 V adapter and runs without fans, so it adds no audible noise to a quiet workspace. LED indicators on the front panel show the active computer at a glance. Power consumption scales with the attached USB 3.0 devices and monitor load.

Compact Metal Chassis And Wired Remote

The enclosure measures 16 x 6.5 x 3 centimetres and fits neatly behind monitors or under a desk. Each computer requires two HDMI cables plus one USB 3.0 cable, all supplied in the box. A wired remote duplicates the front push-buttons, allowing the switch itself to be tucked out of sight while ports remain accessible.

Questions about this item

How do I connect the KC-302AS to three computers and two monitors, and which step do people most often miss?

Each computer needs two HDMI cables and one USB 3.0 cable plugged into its matching INPUT A and INPUT B ports; the step most often missed is connecting the USB 3.0 cable for every PC, without which keyboard and mouse sharing will not work.

What maintenance or replacement will the KC-302AS need over time?

The unit has no user-serviceable parts; only the supplied 12 V power adapter or the USB 3.0 and HDMI cables may need replacement if they become damaged or fail.

What is the first limit I will hit when running the KC-302AS at 4K 60 Hz for long periods?

The 4K 60 Hz signal requires both the computer and the monitor to support 4K 60 Hz and HDMI 2.0 cables; if any link in that chain is limited to a lower spec, the switch will fall back to 2K at 120 Hz or 144 Hz.
