The KH1508A KVM switches are control units that allow IT administrators to access and control multiple computers from a single PS/2 or USB KVM console (keyboard, monitor, and mouse). Operators can take control of up to 8 computers. By daisy chaining up to 31 additional switches, as many as 256 computers can be controlled from the original KVM console. These switches have been designed with unique and powerful features that enable administrators to manage their entire server room and data centre devices easily and conveniently. For example, the advanced Adaptor ID feature stores the Adaptor Cable's configuration information - such as its ID, port name, OS, keyboard language, etc. This feature allows administrators to relocate servers to different ports without having to reconfigure the adapters . Other advances found with these switches includes enhanced video quality - extending the distance to the servers to up to 50 m at a resolution of 1280 x 1024. A KH1508A installation provides one of the best, and most economical, solutions ATEN offers to the SMB market. There is no better way to save time, space, and money than with a KH1508A KVM switch.
