SwitchMan is a unique KVM switch that combines advanced, professional-grade technology with an easy-to-use design that fits naturally on your desk. Color-coded connectors and premium, ultra-thin coax cables make installation easy. The SwitchMan KVM allows control of up to four computers from a single keyboard, video and mouse. SwitchMan's COMBO models have a built-in USB 2.0 Hub, which allows the sharing of multiple USB-supported devices, including scanners, digital cameras and printers to be shared among multiple computers. Plus, the SwitchMan COMBO models offer audio switching functionality that lets you share a single microphone and stereo speakers among multiple computers. SwitchMan includes the same bulletproof reliability as all Raritan enterprise class products used in over 50,000 data centers worldwide. Raritan's KVM switches are designed with "keep-alive" circuitry that eliminates annoying mouse and keyboard lock-ups when switching between computers. No matter how you use SwitchMan, you'll enjoy smooth, flawless start-ups, switching and operation.
