## Long description

The StarTech.com 4-Port KM Switch GL3523 lets you control a keyboard, mouse and audio peripherals across up to four computers. It uses USB connections for keyboard and mouse, supports 3.5 mm audio pass-through and USB audio, and is designed to simplify multi-computer workflows by enabling cursor roaming between displays and multiple switching methods.
Advantages
Mouse roaming allows seamless cursor movement across up to four hosts so you can switch control by moving the mouse between monitors. The unit also supports hotkey and push-button switching for universal compatibility with major desktop operating systems including Windows, macOS and Linux. Integrated USB audio and 3.5 mm pass-through let you listen to one computer while controlling another, and visual LEDs plus an audible buzzer indicate the selected port. The compact black design and TAA compliance make it suitable for managed workspaces.
Suitable for
Shared workstations with one keyboard and mouse for multiple PCs
Multisystem setups where each computer has its own monitor
Environments requiring quick switching between 4 computers (office, lab, control room)

How to use
Connect a single USB keyboard and USB mouse to the KM switch’s console ports, then connect each of up to four computers to the corresponding host USB ports and optional 3.5 mm audio jacks. Arrange each computer to its own monitor and select a preset monitor layout that matches the physical arrangement. Move the mouse across screens to switch control using Mouse Switching, or use the hotkey or push-button on the unit to change the active computer. Note that when Mouse Switching is enabled on a computer with multiple monitors, control is restricted to that computer’s primary display.
Usage recommendations
For best results, set each computer’s primary display and choose the matching preset layout before enabling Mouse Switching. Use the hotkey or push-button if a host’s display configuration prevents cursor roaming. Ensure USB audio drivers are installed on the host to use USB audio pass-through.
