Aten Corp KH2516A 16 Port 2 User CAT5 KVM Switch

The KH2516A KVM allows access and control of multiple computers from a single PS/2 or USB KVM console. As many as two operators may simultaneously and independently control of up to sixteen computers.
Daisy chaining up to 31 additional switches allows control of a maximum of 512 computers from the original KVM console. The built in auto-sensing feature automatically recognizes the position of each station on the chain and for easy identification a seven-segment front panel LED displays that station's position in the chain.
RJ-45 connectors in conjunction with CAT 5e/6 cable connected to PS/2 or USB CPU modules make for a compact efficient wiring configuration. Individual CPU modules ensure compatibility with PC MAC SUN and Serial devices and allow the various units to coexist in the same installation.
Access to a particular computer in the installation is easily accomplished by pressing the corresponding front panel port selection switch; entering hotkey combinations from the keyboard; by means of an OSD (On Screen Display) menu system or a convenient Auto Scan function which permits automatic scanning of selected computers.
