Hardware Installation
Before installation, please make sure all of peripherals and computers have been turned off.
The installation of below is based on 8 port-Rack Mount KVM Switch. Please follow the
same installation procedure for 4 and 16 port Rack Mount KVM Switch.
Step 1
Find a convenient place to put your KVM Switch. Its 19” rack mount form factor makes it
ideal to be mounted on 19” rack. When mounting to a rack, attach the included brackets to
the sides of the KVM Switch. Take note of the length of your cables so that your computers,
KVM Switch, keyboard, mouse and monitor are distanced properly.
Step 2 (Local Console)
Connect the monitor to the KVM Switch. Connect the attached cable, or the one included
with your monitor, to the HDDB-15 female port on the back of the KVM unit marked with the
monitor symbol at the CONSOLE connector.
Download from Www.Somanuals.com. All Manuals Search And Download.
Step 3
Connect the keyboard to the KVM Switch. If you have an AT type keyboard, you will need
an AT to PS/2 adapter.
Step 4
Connect the mouse to the KVM Switch.
Step 4-1 (Remote Console)
Extending your PC console up to 500 feet away:
(1) To make sure the CAT5 cable is straight through type.
(2) Plug one end of the CAT5 cable into RJ-45 connector of PS/2 KVM switch and the other end
into KVM CAT5 receiver RJ-45 port.
(3) Connect remote keyboard, mouse and monitor with PS/2-EXTENDER-RECEIVER “KB“,
“MS“ and “Monitor” interface.
(4) Connect CAT5 receiver PC port with PC console port by using 3-in-one KVM cable.
NOTE:
1. Local console and Remote console of KVM Switch will have the same
priority to control computer, just like a PC connected to two consoles. The
remote console can control both the local PC and remote PC connected to
KVM switch; however, the local console can only control the PCs on local
side. There will be a conflict, if the local console and remote console
access the computer simultaneously. Please don’t use local console and

remote console at the same time.
2. When the video signal is foggy or un-cleared on the screen, please check
if VGA connector is connected properly, or the VGA resolution is too high
for the length of cable being used. If the problem happened at VGA
resolution, please shorten the CAT5 cable length or reduce VGA
resolution. It is highly recommended to use “optimal CAT5 cable length “to
get the best video quality and don’t waste unnecessary CAT5 cable. High
VGA resolution is up to 1280X1024 and CAT5 cable length
could up to 500 feet approximately.
3. There is a Dip Switch on the rear site of KVM switch. The factory default
value is “ OFF/ OFF “ state. When you use the CAT5 cable length is over
300 feet, please set DIP Switch to “ ON/ON “ state. The other setting
likes “ON/OFF” or “OFF/ON” state is reserved for future application.
Step 5
PC port connectors of the KVM switch are HDDB-15 pin type. Plug one end of the calbe
which is HDDB-15 pin male connector to the selected computer port on the rear of KVM
switch unit. The other end of cable which have three connectors: a HDDB-15 pin male type
for PC video, a Mini Din 6 pin female type for keyboard and a Mini Din 6 pin female type for
mouse, will be attached to keyboard, mouse and monitor ports of computer respectively.
Repeat the same procedure to all of PCs.
The Rear Side of PC
Step 6 (Optional)
If your computer has an AT type keyboard port (Din 5 pin), you will need a PS/2 to AT keyboard
adapter.
The Rear side of PC
Step 7
Check all of the connections carefully. The colors of keyboard and mouse connectors will
help to make sure the keyboard and mouse cables go to the correct ports.
Step 8
Attach the power supply to the KVM unit and plug the other end into an electrical receptacle.

b. To use hot plug function on PC which is powered on before connected to pass through
port, (i.e. the console port is connected to PC directly), please switch from the pass
through port to next port (or say emulation port ) and then switch back to the pass
through port.
c. You may unplug the mouse or the keyboard from the console port and plug it back in at
any time.

Troubleshooting
1. Make sure that all cables are well connected. Label all of cables with the number for
each computer respectively to avoid confusion.
2. To avoid ghosting and degradation, the recommended VGA cable distance is 5
meters maximum. Normally, the cable length is based on driver capacity of your VGA
card. If you need longer VGA cable, please use VGA extender to accomplish your
applications.
3. The recommended PS/2 cable distance is 5 meters maximum. Normally, the cable
length is based on driver capacity of your motherboard PS/2 port. If you need longer
PS/2 cable, please use PS/2 extender to accomplish your applications.
4. Don’t press any keys on the keyboard while the selected computer is booting up.
Otherwise, it might cause the keyboard error or keyboard is not detected at PC side.
5. The computer boot up is fine, but keyboard doesn’t work
z
z
Make sure the keyboard works when it is directly plugged into the computer.
Try a different keyboard, but use only 101, 102 or 104-key keyboard.
6. The Mouse is not detected during PC boot up.
z
z
Make sure the mouse works when directly plugged into the computer.
Make sure the mouse is a true PS/2 mouse. A combo mouse will work just as long as
it is set for PS/2 mode with the correct adapter. Try a different mouse.

When you switch one PC port to another, please set the scan time for 5 sec at least. .
Normally, it takes one or tow seconds for the VGA monitor to change from one
resolution mode to another. So, the scan time is not recommended to be less than 5
seconds.
7. The power switch is off, but the switch still works fine or power adapter is unplugged
from the switch, but the switch still works fine.
KVM Switch unit draws the power source from power adapter and all PC’s PS/2 port.
Some PC’s PS/2 port can support enough power for the switch, but some PC’s PS/2
port ( like laptop, notebook computer…etc.) is unable to supply enough power for the
switch. In order to make sure the system can work steadily, please do not set power
switch as off state or remove the power adapter from the switch.
Although the PCs connected to KVM Switch unit are able to support enough power
to the stand alone switch, KVM Switch unit still needs a power adapter for daisy
chain more banks.
8. If you forget the “ password ” you typed, please contact your supplier.
9. CAT5 Console Receiver power LED is not ON, to make sure power adapter is
connected to KVM CAT5 receiver.
10. No video signal is displayed on the remote monitor.
a. It might happen because VGA cables & connecter and CAT5 cable &
connector is loosed or disconnected or VGA cable was not attached to
computer during boot up process.
b. Or power adapter is not connected to receiver.
11. When video signal is foggy or un-cleared on the screen, please check if VGA
connector is connected properly, or if the VGA resolution is too high for the length of
cable being used. If the problem happened at VGA resolution, please shorten the
CAT5 cable length or reduce VGA resolution. It is highly recommended to use
“optimal CAT5 cable length “to get the best video quality and avoid wasting
unnecessary CAT5 cable. VGA resolution is up to 1280X1024 and CAT5
cable length could up to 500 feet approximately.
