Step 1
Find a convenient place to put your DKVM-8E. Its 19” rack
mount form factor makes it ideal mountable on 19” rack.
When mounting to a rack, attach the included brackets to
the sides of the DKVM-8E. Take note of the length of your
cables so that your computers, DKVM-8E, keyboard,
mouse and monitor are distanced
properly.
Step 2
Connect the monitor to the DKVM-8E. Using the attached
cable, or the one included with your monitor, connect it to
the HD DB-15 female port on the back of the KVM-08
labeled with the monitor symbol at the CONSOLE
connector.

Step 3
Connect the keyboard to the DKVM-
8E. If you have an AT
type keyboard, you will need an AT to PS/2 adapter.
Step 4
Connect the mouse to the DKVM-8E.
Step 5

Now the PC 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 of the PC
and the rear panel ofthe DKVM-8E unit to the connector
labeled VGA. Repeat this for all PCs.
Step 6
Connect the first computer’s mouse cable to the DKVM-8E.
If using a PS/2 cable, connect one end to the PS/2 mouse
port on the computer, and the other end to the PC1 PS/2
mouse port on the back of DKVM-8E. If using a serial
mouse cable, connect one end to a DB-9 serial port on the
computer, and the other end to the PC1 DB-9 serial mouse
port on the back of the DKVM-8E.

DKVM-
8E. Using another PS/2 cable connect one end to
PS/2 keyboard port on the computer, and the other end to
the PC1 keyboard port on the back of DKVM-8E
. If your
computer has an AT type keyboard port, you will need a
PS/2 to AT keyboard adapter.
Step 8
Double-check all of the connections. Make sure the
keyboard and mouse cables go to the correct ports.
Step 9
Repeat step 5 to 8for the remainder of the computers.
Step 10
Attach the power supply to the DKVM-8E 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.

NOTE:
Please be remind to plug in power adapter.
Although the
PCs connected to DKVM-
8E are able to support enough
power to the stand alone switch, DKVM-
8E still needs a
power adapter for daisy chain more banks. If you forgot to
plug in powe
r adapter on the status of daisy chain, it may
cause the unpredictable behavior or shut down the PC.
Step 11
Nowpower up all computers simultaneously. 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.
NOTE:
Please don’t switch the PC port (i.e. Don’t 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.
