The 4-Port GCS24U USB Cable KVM Switch from IOGEAR® allows users to share a VGA monitor, a USB mouse, and a USB keyboard between four computers. Users can switch between computers using a manual switch located on a wired remote control that can be placed conveniently on your desk. This device offers an out-of-box/entirely plug-in-play solution with no additional cables or software installation needed; you can simply connect the cables to the computers. Compatible with multiple operating systems including Windows®, Sun, and Mac, it is also powered through the USB bus and thus does not require a power supply to run. With all these features, it is the ideal entry level KVM that will allow them to multitask with four computers at their disposal.
