Aten CS724KM4-Port USB KMSwitch

Aten CS724KM — 4-port USB KM switch (keyboard and mouse only) with Boundless Switching, allowing a single keyboard and mouse to control up to four computers across independent monitors by moving the cursor across screen borders.

The Aten CS724KM is a KM switch — it shares a keyboard and mouse across four computers without routing video. Each computer has its own dedicated monitor; you switch control focus by moving the mouse cursor to the edge of one screen and it appears on the next computer's display, just like a multi-monitor extended desktop. This is ATEN's Boundless Switching technology — there are no hotkeys or button presses required to change focus; the cursor simply crosses the screen boundary. The CS724KM supports extended desktop layouts of up to sixteen monitors in total, making it suited to control rooms and multi-screen workstations where multiple computers must be managed side by side. Two units can be daisy-chained for control of up to 8 computers. Bus-powered — no external power adapter required. A GUI-based configuration utility (Windows) lets you map cursor movement paths to match your physical monitor layout. Independent hotkey switching of keyboard/mouse, USB peripheral, and audio focus is also supported. RS-232 control available for automation and integration.
