The KH1516A 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 16 computers. By daisy chaining up to 31 additional switches, as many as 512 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 center devices easily and conveniently. For example, the advanced Adapter ID feature stores the Adapter 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 . Another advantage found in these switches is Full HD video quality – extending the distance to the servers to up to 30 m at a resolution of 1920 x 1200 *. In addition, the switches are compatible with ATEN KVM adapter cable. This allows flexible interface combinations (PS/2, USB with VGA, DVI, HDMI and DisplayPort video interface, Sun and serial) to control all computer types. A KH1516A 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 KH1516A KVM switch. Note: *The video quality of KH1516A has been enhanced to Full HD.
