The MiniView Ultra G-CS138 KVM Switch is a control unit that allows access to multiple computers from a single console keyboard, monitor, and mouse). Before the development of the MiniView Ultra, the only way to control multiple computer configurations from a single console was through a complex and costly network system. Now, with the MiniView Ultra G-CS138, you can easily access multiple computers in a cost-effective manner. A MiniView Ultra G-CS138 unit can control up to 8 PCs. Units can be cascaded to three levels, which means that up to 73 MiniView units can control up to 512 PCs - all from a single console. Setup is fast and easy; plugging cables into their appropriate ports is all that is entailed. There is no software to configure, so there is no need to get involved in complex installation routines or be concerned with incompatibility problems. Since the MiniView Ultra CS-138 intercepts keyboard input directly, it works on virtually any hardware platform and with all operating systems. The MiniView Ultra G-CS138 provides three convenient methods to access any PC connected to the system. In addition, a powerful Quick View Scan feature allows you to auto scan and monitor the activities of all operating PCs on the installation one by one. There is no better way to save time and money than with a MiniView Ultra G-CS138 installation. By allowing a single console to manage all the attached PCs, the MiniView Ultra GCS138 eliminates the expense of purchasing a separate keyboard, monitor, and mouse for each PC as well as saving all the space they would take up. It also eliminates the inconvenience and wasted effort involved in constantly moving around from one PC to another.
