Introduction
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.

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=.

Step 3. 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.
Step 4. 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.

Step 5. 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.
Step 6. 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.

Step 7. 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.
Step 8. 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.
Step 9. 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

8
choose the next computer and verify the
functionality in the same way. If you find errors, re-
check all cables for proper connections before
going to the troubleshooting section of this manual.
Note : 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.
