Installation

WARNING!

Before attempting to connect anything to the
DKVM-8E or the computers, make sure everything
is powered off . Otherwise, plugging and
unplugging cables may cause irreversible damage
to your computers and the DKVM-8E.

Please follow the steps below closely and in the order as
shown, otherwise, keyboard and/or mouse errors may
occur.

- 5 -

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 DKVM-8E

labeled with the monitor symbol at the CONSOLE

connector.

- 6 -

Step 3

Connect the keyboard to the DKVM-8E.

Step 4

Connect the mouse to the DKVM-8E.

Step 5

- 7 -

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 of the 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.

- 8 -

Step 7

Connect the first computer’s keyboard cable to the
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.

Back of PC

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 8 for 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.
Switch on your monitor.

OTE

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 power adapter on the status of daisy chain, it may
cause the unpredictable behavior or shut down the PC.

Step 11

Now power 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.

N

OTE

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.

Usage

The power on state of DKVM-8E

When you power on KVM switch, it will ask for the
password, the default password value is eight
zero –“ 00000000 “. Please key in eight zero and enter the
same value at retype field.

Note:

Before you are not familiar with the operation of OSD
manual, please don’t change the password – i.e. keep the

maintain PCs as follows:

- 16 -

1. A PC can be disconnected and reconnected to the
same or different port of the DKVM-8E without having
to power it off as long as it is not the Daisy-chain port
or pass through port.

2. When the pass through port is active and selected,
you must switch to a different port before you change
the configuration, and then you can switch back to the
pass through port.

3. You may unplug the mouse or the keyboard from the
console port and plug it back in at any time.

N

OTE

Some O.S. (Operation Systems) like SCO Unix are unable
to support “ Hot Plug ” function. If you apply “Hot Plug” to
this kind of O.S., it will cause unpredictable behavior or
shut down the PC. Before attempting to use “ Hot Plug ”,
please make sure your O.S. and software driver supports
the “Hot Plug” function.

Monitor/Video Problems

Q: I am getting ghosting shadowing or fuzzy images

on my monitor. What do I do?

˙

A:

Check the cables and make sure they are inserted

properly.

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 is directly plugged into the

computer. Rebooting is necessary when trying this.

If the computer still does not detect the mouse, then

˙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 a s 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.

Q: When I switch from one port to another, mouse

movement is completely erratic. What do I do?

- 26 -

A : Switch the console port to the problem PC port and power

on this PC again to get the mouse.

Problems with power supply

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 ?

A: DKVM-8E draws the power source from power adapter

and PC’s PS2 port. Some PC’s PS2 port can support

enough power for the switch, but some PC’s PS2 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

to off state or remove the power adapter from the switch.

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.
