The Master View Plus CS124U represents a revolutionary new direction in KVM (Keyboard, Video, Mouse) Switches. The CS124U is a control unit that allows access to four (4) computer systems from a single USB keyboard, USB mouse and monitor console in a cost effective manner. There are three (3) convenient methods to access the computers: (1) push button port selection switches located on the unit's front panel; (2) Hotkey combinations; and (3) selecting from menus provided by the OSD (On Screen Display) feature. A powerful Quick View Scan feature also allows you to autoscan and monitor the activities of all operating computers on the installation one by one. Setup is fast and easy; simply plug cables into their appropriate ports. There is no software to configure, no installation routines, and no incompatibility problems. Since the CS124U intercepts keyboard input directly, it worls on any hardware platform and with all operating systems. The CS124U represents the second generation of KVM switches incorporating USB technology to handle the keyboard and mouse data connection between itself and the connected computers. There is no better way to save time and money than with a Master View CS124U installation. Since a single console manages all of the computers, the CS124U setup: eliminates the expense of having to purchase a separate keyboard, monitor, and mouse for each computer; saves all the space those extra components would take up; saves on energy costs; and eliminates the inconvenience and wasted effort involved in constantly moving around from one computer to another.
