Thank you for purchasing the DKVM-2/4 KVM Switch. This
product will ensure easy and accurate control over 2 or 4
PCs through a single console. The DKVM-2/4 is compatible
with mouse and keyboard with PS/2 type connectors. Older
style keyboards or mice can be used with PS/2 adapters in
the case that the device is PS/2 compatible. Most older style
serial keyboard and mice are not compatible with PS/2.
Advanced features like keyboard and mouse emulation for
error free boot-ups and support is also provided for the
Microsoft Intellimouse and Microsoft Intellimouse Explorer.
The DKVM-2/4 supports high resolutions. Resolutions up to
1920 x 1440 are supported with no deterioration of image
quality.
Switching between PCs can be accomplished in two ways:
through keyboard “Hot Key” commands or by using the
convenient front-panel “Select” push button controls.

computers to the D-Link KVM switch unit. First the layout of
front and rear panel will be shown.

Before you start connecting your computers and console
devices to the DKVM-2/4, please make sure that everything
is powered off.

Note:
Please make sure the mouse you are planning to
use is a 2 Button or 3 Button mouse, and that it is
fully Microsoft Mouse compatible. If your mouse
driver is not Microsoft mouse driver compatible,
please do not uninstall your mouse driver or the
existing driver from the PC and then install the
Windows native mouse driver.
Please follow the steps below closely and in the order as
shown, otherwise, keyboard and/or mouse errors may
occur.
Step 1.
Place the DKVM-2/4 in a convenient location. Its
small size makes it easy to place on the desktop.
Do take the length of the cables in consideration
when placing the KVM switch unit.
Step 2.
We will now connect the console devices. Connect
your monitor to the DKVM-2/4. The 15-pin
connector coming from your monitor must be
inserted into the unit on the rear panel. Connect it
to the 15 pin HDDB connector labeled
=MONITOR=.

Page 7
Step 3.
Step 4.
Connect your PS/2 keyboard and PS/2 mouse to
the front panel of the DKVM-2/4. The connections
should be made to the two 6-pin Mini DIN
connectors labeled =CONSOLE= as shown below.
Now the PC connections will be made with the
monitor (VGA) connections. Connect a VGA cable
(15-pin HDDB Male / Male) with the Male side to
both the PC and to the connector labeled VGA on
the rear panel of the DKVM-2/4 unit. Repeat this
for all PCs.

Page 8
Step 5.
Step 6.
Now connect the PS/2 mouse cables from your
computers to the DKVM-2/4 unit. Connect a mouse
cable (6-pin Mini DIN Male / Male) to the PC and to
the connector with the mouse symbol on the rear
panel of the DKVM-2/4 unit. Repeat this for all
PCs.
To finish the hardware installation, connect the
PS/2 keyboard cables from your computers to the
DKVM-2/4 unit. Connect a keyboard cable (6-pin
Mini DIN Male / Male) to the PC and to the
connector with the keyboard symbol on the rear
panel of the DKVM-2/4 unit. Repeat this for all
PCs.

Page 9
Step 7.
Step 8.
Step 9.
Now make sure to verify all cables. In particular,
keyboard and mouse cables should be checked
because they are easily switched and they use the
same type of connector.
Attach the power supply to the DKVM-2/4 unit and
plug it into a power outlet. You will see the LED for
Port 1 light up, and you will hear a beep. Switch on
your monitor.
Now power up all computers simultaneously. The
first computer that is connected to port PC1 will be
shown on the monitor. You may check to see if the
mouse and keyboard work after the system has
booted up. If this is OK, use the “Select” button to
7
Page 10
Note
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 troubleshooting section of this manual.
:
Please do not switch the PC port (i.e. Do not
press the push button of KVM switch or run hot
key) while the computers are under their boot-up
process.
Normally, during boot-up process, each PC will
communicate with the keyboard and mouse. If
you switch PC ports on the KVM at this moment,
it will cause communication errors or initialization
failures between PC and keyboard or mouse.

Using the DKVM-2/4
The DKVM-2/4 switch unit provides two ways to select
which computer is the active system. Use either the “Select”
button on the unit, or make use of the keyboard “Hot key”
commands.
You may notice that the mouse cannot be used for around 2
seconds when the DKVM-2/4 switches to another computer.
This is normal and is caused by synchronization that makes
sure the mouse operates properly.

In Auto-Scan mode, the DKVM-2/4 unit will switch to the
next computer every 10 seconds. This means that all
computers will be shown on the monitor in a row, starting
with the first computer after the last one has been shown.
10
Page 13
In this mode, there is no mouse or keyboard control, which
is needed to prevent errors. Erratic input will result if a
mouse move or keyboard key press is given just as the unit
switches to the next computer.
To exit Auto-Scan mode, press the SPACE BAR. The
DKVM-2/4 will stop at the last computer shown.

.
The computers boot properly but I cannot use the
mouse. What can be the cause?
One of the following may be the case:
Please verify that the mouse is plugged into the
DKVM-2/4 unit properly.
Make sure the mouse works properly when plugged
into a computer directly. You will need to reboot the
system to test this.
Try using a different mouse.
Verify that the mouse complies with the PS/2
standard. A combination mouse will work, but it must
be set to PS/2 mode and the correct serial mouse to
PS/2 adapter must be used. A serial mouse with a
serial - PS/2 adapter will not work, since the mouse
signals do not comply with the PS/2 standard.
Make sure that the power adapter is plugged in at
both ends and that it is working correctly. Its rating
must be 9V 600mA.

Page 16
When I switch between computers, mouse movement
becomes random. What can be the cause?
One of the following may be the case:
Verify that your computers do not have more than
one mouse driver installed. Make sure that the driver
is for a standard PS/2 or fully Microsoft compatible
PS/2 mouse. Also check with the mouse vendor to
verify you are using the latest mouse driver.
Check your config.sys and autoexec.bat files (if you
run Windows that is) and verify that only one mouse
driver is loaded.
If a special mouse is used, such as a cordless or
scrolling mouse, make sure you use generic PS/2
mouse drivers. A non-standard PS/2 mouse may
have extensions on the PS/2 protocol that are not
supported by the DKVM-2/4 unit.
Do not move the mouse or press any mouse buttons
while switching from one system to the other.
Try resetting the mouse by unplugging it from the
DKVM-2/4 unit for about 3 seconds. Mouse
movement will now be correct again.
Before booting up any PCs, the DKVM-2/4 unit must
be powered-up. But before powering the DKVM-2/4
unit up, the mouse and keyboard must be
connected. Any deviation from this power-up
sequence may lead to erratic behavior of the
systems.

Please verify that all video cables are inserted
properly.
It may be that your resolution or refresh rate is too
high. Try a lower refresh rate, or try lowering the
resolution.
Your video cable may be too long. Video signals are
high frequency signals and are therefore subject to
interference. Please use video cables that are as
short as possible.
Make sure that the power adapter is plugged in at
both ends and that it is working correctly. Its rating
must be 9V 600mA.
