Product Name: ATEN Masterview Pro KVM Matrix Switch. (2-Consoles x 8-PCS) (CS228). 
Leading our foray into the multi-user switch arena is
ATEN's CS228. With support for two users and up to eight
      attached computers, this unit is perfect for testing benches and other
      multi-user environments. Multilevel password protection, built-in OSD
      (On-Screen Display) and full multimedia sharing are just a few of the
      enhanced features the CS228 supports. Of course, the CS228 also supports
      many of the features that make ATEN KVM switches stand above the
      competition, including support for up to 1920 x 1440 flicker-free video
      resolution, Plug-n-Play monitors and most advanced wheel mice. There's no
      better way to manage a multi-user server room or testing bench than with
      the CS228.
      
      Password protection is provided in order to prevent unauthorized access to
      the computers. Responding to the growing use of audio, the CS228 has built
      in microphone and speaker support.
      
      Because of its multiconsole design, the CS228 cannot be daisy chained to
      another CS228; Instead, the CS138A serves as the cascading unit. Up to
      eight CS138As (using 2L1603P/2L1603P/2L1605P as the cascading cable) can
      be chained to the CS228, for a total of up to 64 connected computers.
