special configuration. Cascaded configuration expands system ability and
allows you to select computers connected to the Master or Slave. After
connected, KVM Switches automatically configure Master and Slave.
Note: CAT5 8-PORT/16-PORT KVM should be the master KVM Switches,
and the second & third layers could use Standard KVM Switches
( Recommends Combo KVM Switches connected to 2nd & 3rd layers ).
To Install cascade chain, please follow the instruction below:
A. Please turn off computers and devices when you start to install KVM
Switch.
B. Uses the custom combo 4-in-1 CAT5 dongle (DS-19202) (See Figure 6)to

Switch. The connection between KVM cascaded to KVM must be
connected through PS/2 connection. ( Please refer to Figure 10 ).
C. You can do console Master KVM Switch via either USB and/or PS/2
keyboard and mouse at will.
D. Plug in the power adapter of the first level Master KVM Switch and
connect Master KVM switch to computers.
E. Next, plug in power adapter for each level Slave KVM Switch and connect
Slave KVM switch to computers .
