Product information

Description

The LevelOne KVM Switch KVM-0421 is a 4-port USB VGA KVM that lets you control up to four USB-enabled computers from a single keyboard, mouse and monitor while providing audio support. The compact unit supports VGA video at up to 2048 x 1536 pixels and connects each computer’s keyboard, mouse and audio ports to the switch for centralized control. The switch is plug-and-play, requires no external power supply or additional drivers, and supports both Windows and Macintosh platforms.

Advantages

The KVM-0421 combines USB keyboard and mouse sharing with audio switching and a high-resolution VGA output, enabling simultaneous or independent PC and audio selection. It offers push-button, keyboard hotkey and software-based switching, an LED status display for quick activity checks, hot-plug support for maintenance without shutdown, and USB-powered operation for a simple installation.

Suitable for

  • Small offices or workstations that need to manage multiple desktops from one console
