The Aten KH2516 is an 16 port Cat 5 KVM Switch which is a dual channel device, allowing two operators to independently and simultaneous access up 16 directly connected computers, and up a maximum of 4096 servers through three level cascading.  Cascading is achieved via dedicated RJ-45 cascade ports and Cat 5e cabling. Both, first level consoles are able to access all 4096 computers in the installation, on the second tier, one console can access second and third level servers, and one console on the third level can access third level servers.  Security consists of two level access (Administrator and User) password / user name protected. The Administrator can set user access on a port-by-port basis, and as many as 96 user accounts can be created.  The KH2508 Cat5 KVM Switch supports mixed environments of Windows, MAC , Linux, Unix, Novell, and OS/2 and employs keyboard emulation for special Mac and Sun keys.

Question: Hi, what is maximum supported resoltion for short distances, i.e. does the switch manage full-hd or even up in distances of 10 to 20 ft?
Answer: Thank you for your inquiry. According to the manufacturer, the maximum resolution for this device is 1600x1200@60Hz; so unfortunately, it would not be able to support full-HD resolutions.

Answer: Thank you for your inquiry,

It does; The Aten KH2516 has been designed to fully support both Cat 5e & Cat 6 cables.
