the server rack …..
If you are using any PS/2 computer: Please
make sure all of your PS/2 computers should be
powered off before connecting to the LCD KVM
Switch. Otherwise, the LCD KVM Switch system
might not be properly set up. However, USB
computers do not have this limitation.
Step 1. Make sure (at least the PS/2) computers that
are to be connected to the LCD KVM switch
are powered off. If not, power them off
before you proceed with the following steps.
Step 2. Connect the shared keyboard, mouse and
monitor to the console connectors on the rear
of your (master) LCD KVM switch. Power on
the LCD KVM Switch by connect power cord
and trun on the Power switch (found on the
front edge of the keyboard tray.

Quick Installation Guide
If you want to daisy-chain multiple KVM
Switches, go to step 3. You can daisy-chain up to 8
levels of KVM Switches with a maximum of 120
computers connected.
Step 3. Use the daisy-chain cable (M-HDB15HDB15-F) to connect the DaisyChain OUT
Port (HDB 15 female) of the LCD KVM
Switch to the DaisyChain IN Port (HDB 15
male) of the second KVM switch (Prima
4/Pirma 8/Prima 16). Connect the power cord
to the second switch to power it on.
Step 4. If you have yet another Prima switch to be
daisy-chained, just repeat Step 3 to connect
them. You can daisy-chain up to 16 units of
KVM switches. Plug a terminator onto the
Daisy-chain Out Port of the last KVM
switch unit.
Applicable models: 8/16-port Cascadable rackmount 15”/17”/19” LCD KVM Switch
The special KVM cable provides a PS/2 keyboard
connector, a USB connector and a HDB video
connector for the computer connection. When
connecting with a USB computer, just plug the USB
connector to it and leave the PS/2 connector free.
When connecting with a PS/2 computer, just add one
USB-to-PS/2 adapter to the USB connector and you’ll
have a PS/2 connector for mouse. Do not connect
USB connector and PS/2 keyboard connector
to a computer at the same time.
Step 6. Power up the connected computers. After
your computer is powered up the keyboard and
mouse will be recognized and now you can
begin operating the switch.
Easy Operation
There are two ways to select a specific computer,
using either keyboard hotkey sequence or OSD
Keyboard hotkeys
A keyboard hotkey sequence consists of at least
three specific keystrokes: See Quick Reference Sheet
Hotkey sequence = ScrLk + ScrLk + Command key(s)
The two consecutive ScrLk keystrokes should be
pressed within 2 seconds and the following command
key(s) should also be pressed within 2 seconds in
likewise manner. Otherwise, the hotkey sequence will
not be validated.
For detailed Hotkey sequences
corresponding functional commands.
No Terminator required if only using a single unit.
Step 5. (Now your KVM switch or daisy-chained KVM
Switches should have been powered-up and
initialized….) Connect each of your
computers to a computer port on the rear of
the switch(es). You should use the special
USB PS/2 KVM cable (with the USB-to-PS/2
adapter) for connection to a USB computer
(PS/2 computer).

1. OSD Menu control is only available when the OSD menu is activated on the screen. To activate the OSD menu, use the hotkey sequence ScrLk + ScrLk + (Space Bar). For detailed OSD operation reference,
please refer to the User Guide. When OSD Menu is active, the mouse will be locked until the OSD Menu is off. To reset OSD menu to default, just use a pointed needle to press the recessed opening (without
marking) just beside the DC jack on the back panel for several seconds.
2. Note that a, b, y and z each denotes a number key. (ab) = 01 ~ 16 ; (yz) = 01 ~ 08. For example, ScrLk + ScrLk + 03 + 06 is for bank 3 port 6. When using a single KVM Switch configuration, the default bank no.
is 01, therefore hit ScrLk + ScrLk + 01 + 12 for port 12 for a single KVM Switch configuration.
3. The password is up to 8-character length. You should remember the password since it is required for access to your KVM switch once you enable the password protection for your KVM switch. However, if you
forget the password and thus are blocked from KVM access, you should contact your local dealer for tech support.
