For computers with Keyboard Power On function, please unplug the power cords
in advance. Otherwise, the switch might not work properly.
If your computeres work under Windows 98, please connect KVM switch to
computers via PS/2 ports, because Windows 98 does not support installation at
first time as through USB HID installation driver.
Some kind of old computers must enable USB setting in BIOS in advance to
make USB interface work.
This KVM switch does not guarantee to fully support USB keyboard with USB
HUB.

10
(Optional) Connect the USB connectors of USB A-mini cable to the host
computer and the CAT5 8-PORT/16-PORT IP-KVM module while for remote
mass storage control.
Connect one end of Ethernet cable to ethernet jack of CAT5 8-PORT/16-PORT
IP-KVM, and the other end to the Remote Console computer.
4.3.2. Console connection:
Plug keyboard, mouse and monitor to the console ports on the real panel of
CAT5 8-PORT/16-PORT IP-KVM (Figure 5).
Figure 5: Console connection
4.3.3. System connection:
Please use Custom CAT5 cable to connect your computers.
Please refer to the figures and instruction shown below for System connection.
Note: Please contact your dealer to purchase the custom combo 4-in-1 CAT5
dongle (DS-19202) if you need.

You can connect CAT5 8-PORT/16-PORT IP-KVM to computers via three methods
shown below:
A. Connect USB, PS/2 (keyboard/mouse) and VGA connectors to computers.
We recommand users to connect computers in this way.
Figure 7: USB & PS/2 (Keyboard & Mouse) and VGA connected
B. Connect only PS/2 (keyboard/mouse) and VGA connectors to computers.

4.4. Cascade Chaining
CAT5 Combo Free 8-Port & 16-Port KVM switch support 3 level cascades; control
up to 8/64/512 PCs ( for 8-Port only ) and 16/256/4096 PCs ( for 16-Port only ),
from a single console; cascaded chaining units do not need 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 IP-KVM should be the master KVM Switches,
and the second & third layers could use Standard KVM Switches
without Over-IP function ( 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
connect one or more Slave KVM Switches to any PC port of Master KVM Switch.
The connection between KVM to KVM must be connected through PS/2
connection. ( Please refer to Figure 7 & Figure 8 ).
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.

--
13
E. Next, plug in power adapter for each level Slave KVM Switch and connect Slave
KVM switch to computers .
F. The power on sequence should be:
1. Master KVM Switch
2. Second level Slave KVM Switch (connecting to Master KVM Switch) if any.
3. Third level Slave KVM Switch (connecting to second level Slave KVM
Switch) if any.
4. All computers connecting to Master/Slave KVM Switch.
G. After all KVM Switches are powerd by power adaptor, trun on the computers.
Initial Plug-in Process:
Please plug in the Master KVM Switch first before turning on any other
devices like montior or computers.
Hot plug and Hot Swap:
Combo Free 8-Port & 16-Port KVM switch support Hot plug and Hot swap
function.
