Chapter 2: Hardware Installation
Connecting Computers
WARNING!
Before attempting to connect anything to the KVM switch or the computers, make
sure the KVM switch is powered off. Otherwise, plugging and unplugging cables
may cause irreversible damage to your computers and the KVM SWITCH.
Step 1 Connecting VGA of Console
The Console connections will be made with the monitor (VGA) connections first. Connect a
VGA cable (15-pin HDDB Male / Male) with the Male side to both the Monitor and the rear
panel of the KVM SWITCH unit monitor connector.
Step 2 Connecting Keyboard & Mouse of Console
Connect the keyboard and mouse to the KVM SWITCH. If you have an AT type keyboard, you
will need an AT to PS/2 adapter.
Step 3 Connecting VGA of Computer
Now the computer connections will be made with the monitor (VGA) connections first. Connect a
VGA cable (15-pin HDDB Male / Male) with the Male side to both the computer and the rear
panel of the KVM SWITCH unit to the connector labeled with the display symbol(VGA). Repeat
this for all computers.

Chapter 2: Hardware Installation
Step 4 Connecting Keyboard and Mouse
Connect the first computer’s mouse/keyboard cable to the KVM SWITCH. If using a PS/2 cable,
connect one end to the PS/2 mouse/keyboard port on the computer, and the other end to the
“Computer 1” PS/2 mouse/keyboard port on the rear of KVM SWITCH. Make sure both mouse
and keyboard have been connected to their appropriate ports. Most cables are color coded to
match the connectors. It is a good idea to check this when connecting the cable. If your com-
puter has an AT type keyboard port, you will need a PS/2 to AT keyboard adapter.
Rear of computer
Step 5 Check Again
Double-check all of the connections. Make sure the keyboard and mouse cables go to the cor-
rect ports.
Step 6 Connecting Other Computers
Repeat step 3 to 4 for the remainder of the computers.
Step 7 Connecting KVM Power
Attach the power supply to the KVM SWITCH unit and plug the other end into an electrical
receptacle. Now you will see the LED for Port 1 light up, and you will hear a beep. Switch on
your monitor.
NOTE:
To keep the KVM switch status in a stable state, please leave the power adapter plugged in.
This is very important when KVM switches are stacked together in a Daisy Chain stack.
Step 8 Turn on all Computers
Now power up all computers together. The first computer will be shown on the monitor. You may
check to see if the mouse, keyboard and monitor work after the system has booted up. If this is
OK, use the “Select” button to choose the next computer and verify the functionality in the same
way. If you find errors, recheck all cables for proper connections before going to the trouble
shooting section of this manual.

Chapter 3: Console Operation
Password Protection
There is an administration password for locking the console display and switching between
managed computers. This password can be set by using the OSD. The password supports up to
8 digits, and only accepts “ A~Z ” , “ 0~9 ” . The default password is “ 00000000 ” . For security
reasons, please change the default password the first time you configure the KVM switch. It is
strongly recommend to write down the new password. If the password is forgotten, you will need
to contact the vendor to erase the password that had been set.
Hot Plug Function
KVM switch supports “ Hot Plug ” function. When mouse/keyboard connection has been
changed from one port to the other, it is not necessary to reboot the managed computer for the
change to take effect.
Example:
Computer 1 is originally connected to KVM switch port 1. When you pull out the
keyboard/mouse/VGA cables from port 1 and plug them into port 2, you won’t need to reboot
computer 1 and you can still control the keyboard/mouse/VGA of computer 1.

Chapter 4:Troubleshooting
General Problems
Q: The OSD menu does not display a “ ” on a channel where a computer is
connected and powered up. What do I do?
Your KVM SWITCH will update “
” every 2 seconds. Using the hot keys to access the OSD menu
again should have re-detected all the active channels.
Q: When cascading the MASTER unit does not see the slave unit(s).
One of the following may be the case:
• Refer to the Installation section for information on how to properly connect the daisy-chain cable.
• Make sure the daisy-chain cable that you are using is the one provided. Using any other cable
will not guarantee proper operation or video quality.
• Reset all the slave units first and then reset master unit to detect the lost slave unit.
• Although a power supply is not necessary to make the slave unit work, try adding a power supply.
Monitor/Video Problems
Q: I am getting ghosting shadowing or fuzzy images on my monitor. What do I do?
One of the following may be the case:
• Check the cables and make sure they are inserted properly.
• Your resolution and / or refresh rate is extremely high, or your cable is too long. Replace your VGA
cables with coaxial, double-shielded cables.
• Check to make sure that the power adapter is plugged in and is working properly. Make sure the
power switch is on.
• Lower your refresh rate and / or screen resolution settings.
Keyboard Problems
Q: The keyboard is not detected, or a keyboard error is reported during boot-up.
One of the following may be the case:
• Check the cables and make sure they are inserted properly in the correct ports.
• Check to make sure that the power adapter is plugged in and is working properly. Make sure the
power switch is on.
Q: The keyboard is not detected, or a keyboard error is reported during boot-up.
One of the following may be the case:
• Check the cables and make sure they are inserted properly in the correct ports.
• Make sure the keyboard works when directly plugged into the computers.
• Try a different keyboard, but use only 101,102 or 104-key keyboards.
• Make sure that the keyboard driver is for 101, 102 or 104-key keyboards, and not old
XT keyboards.
• Check to make sure that the power adapter is plugged in and is working properly. Make sure the
power switch is on.

Chapter 4:Troubleshooting
PS/2 Mouse Problems
Q: The mouse is not detected during boot-up.
One of the following may be the case:
• Check the cables and make sure they are inserted properly in the correct ports.
• Check your computer / motherboard documentation making sure that the PS/2 mouse port
(or IRQ) is enabled.
• Make sure the mouse works when directly plugged into the computer. Rebooting is necessary
when trying this. If the computer still does not detect the mouse, then your computer’s PS/2
mouse port has a problem.
Q: The computer boots up fine, but the mouse does not work.
One of the following may be the case:
• Check the cables and make sure they are inserted properly in the correct ports.
• Make sure the mouse works when plugged into the computer. Rebooting is necessary when trying
this. If the mouse pointer still does not move, then either your PS/2 mouse port or the mouse
itself has a problem.
• Try a different mouse
• 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. A serial-only mouse with a combo mouse adapter WILL
NOT work.
• Check to make sure that the power adapter is plugged in and is working properly. Make sure the
power switch is on.
Q: When I switch from one port to another, mouse movement is completely
erratic. What do I do?
• Switch the console port to the problem computer port and power on this computer again to get
the mouse.
Problems with computers using serial mouse output
Q: The computers boot up fine, but the serial mouse port of computer does not
work
One of the following may be the case:
• Check the adapter and make sure they are inserted properly in the correct ports.
• Make sure the adapter pin out is right.
Q: The wheel on the Mouse does not work on my computer. Why?
One of the following may be the case:
• Make sure the mouse is fully compatible to Microsoft® Intellimouse® or Microsoft®
Intellimouse® Explorer®.
• KVM SWITCH does not support special wheel function of mouse
NOTE:
The KVM SWITCH has integrated mouse conversion technology. This technology converts the PS/2
mouse signals at the console to serial mouse signals.
17
Chapter 4:Troubleshooting
Problem with power switch and power adapter
Q: 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 draws the power source from power adapter and computer’s PS2 port. Some com-
puter’s PS2 port can support enough power for the switch, but some computer’s PS2 port ( like lap-
top, notebook computer…etc.) is unable to supply enough power for the switch. In order to make
sure the system can work reliably, please do not set power switch to off state or remove the power
adapter from the switch.
Although the computers connected to your KVM SWITCH are able to support enough power to the
stand alone switch, the KVM SWITCH requires the power adapter to allow for daisy chaining more
banks of switches.
