Quick Installation Guide
Thank you for purchasing the Addlogix KVM-801PREU-OSD /
KVM-1601PREU-OSD Cascadable Rackmount USB PS/2 KVM
Switch. With our high quality product, users can enjoy countless
benefits from using it.
to 16 units of KVM switches. Plug a terminator onto
the Daisy-chain Out Port of the last KVM switch unit.
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).
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.
Out-of-the-box Installation
Take the KVM Switch out of the box and begin
If you are using any PS/2 computer: Please make sure
all of your PS/2 computers are powered off before connecting to
the KVM Switch. Otherwise, the KVM Switch system might not be
properly set up. However, USB computers do not have this
Step 1. Make sure (at least the PS/2) computers that are to be
connected to the KVM switch are powered off. If not,
power them off before you proceed with the following
Step 2. Connect the shared keyboard, mouse and monitor to the
console connectors on the rear of your (master) KVM
switch. Power on the KVM Switch by attaching the
power adapter cord.
Although the power is constantly fed through the USB or PS/2
interface from the connected computer, it is still necessary to use
the external power adapter for more stable OSD operation and the
cascaded application. Without external power source, the stability
of the KVM system might be compromised.
If you use only a single KVM switch in non-cascaded
application, you should ignore step 3, 4 and 5 and jump directly to
step 5.
If you want to daisy-chain multiple KVM Switches, go to
step 3. You can daisy-chain up to 16 levels of KVM Switches with a
maximum of 256 computers connected.
Step 3. Use the daisy-chain cable (M-HDB15-HDB15-F) to
connect the DaisyChain OUT Port (HDB 15 female) of
the master KVM Switch to the DaisyChain IN Port (HDB
15 male) of the second KVM switch. Connect the power
adapter cord to the second switch to power it on.
Step 4. If you have yet another switch to be daisy-chained, just
repeat Step 3 to connect them. You can daisy-chain up
Front-panel push buttons
The front-panel buttons let you have direct control over KVM
switch operation and channel switching. Simply press a button to
switch to its corresponding channel. See Quick Reference Sheet
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 and their corresponding
functional commands. See Quick Reference Sheet
OSD Menu
To activate the OSD (On Screen Display) Menu, use the hotkey

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
Firmware Upgrade
There are three ways to select a specific computer (on a specific
switch, if you have multiple daisy-chained KVM switches), using
front-panel push button, hotkey sequence or OSD Menu.
This KVM Switch allows its user to upgrade firmware contents
whenever is needed to enhance the compatibility to other devices
or its functions and performance. Use the firmware upgrade cable
for connection to a host PC via the “Daisy-chain IN” port (see
previous configuration diagram). For firmware upgrade procedure,
please refer to Firmware Upgrade Operation Guide.

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.
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.
