This 8 Port USB VGA KVM Switch allows you to control up to 8 USB computers using only one keyboard, mouse and monitor, and features an Audio and Microphone port for each connected computer - allowing you to switch between audio signals as well as between PC ports. To maximize the number of computers that can be controlled from a single point, the USB KVM switch is cascadable - allowing multiple units to be connected (cascaded) together for control of up to 64 computers, ensuring a scalable KVM solution that can be expanded as necessary. To ensure seamless operation, the switch features automatic and manual scan modes, and makes switching between computers as easy as entering the defined hot-key command, or pressing the corresponding front panel push-button. To make configuring and monitoring connections easier, the switch also features a convenient OSD (on-screen display).Based on a slim form factor design that requires only 1U of storage space, this 8 Port USB KVM Switch uses rear cable connections to maximize space efficiency.
