Thank you for purchasing the LKV-9304 / LKV-9308 / LKV­9316 Cascadable Rackmount USB PS/2 KVM Switch! With

our highly reliable and quality product, user can enjoy
countless benefits from using it.

Special User Features

This KVM Switch features some distinguishing features that
help make your server management both hassles-free and
efficient:

Longer Daisy-chaining Cable Length

The KVM Switch supports longer daisy-chaining cable
maximum length of 30M total distance and up to 16 levels of
KVM Switchers.

Advanced Autoscan Modes

The advanced autoscan modes support four scanning modes:
either you can scan ALL computer ports regardless of whether
they are connected with computer or not, or you can only those
Live computers with power feed, or you can specify whether a
computer to be included within the EasyView (EzV) scan group,
and scan only within the EzV group. Furthermore, you can
scan only those Live computers within the EzV group (Live +
EzV). The mode selection can be done on the OSD by
accessing Main / Setup / Autoscan mode.
These diverse selection and combination of scan modes will
allow users a very flexible autoscanning capability with more
subtlety in monitoring specific set of computers.

Title Bar Positioning Alternatives and Timeout

The title bar which shows the computer name can now be
positioned in either left or right position, either with or without a
5-secon timeout option. To select the title bar positioning, just
go to the OSD Main Page / Setup / Title Bar, and select it.

Out-of-the-box Installation

Take the KVM Switch out of the box and begin
installation...

If you are using any PS/2 computer: Please make
sure all of 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 limitation.

Step 1. Make sure computers that are to be connected to the

KVM switch are powered off. If not, power them off.

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 provided AC power adapter.

Although the power is constantly fed through the USB or
PS/2 interface from the connected computers, it is still
recommended to use the external power adapter for more
stability.

If you use only a single KVM switch in non-cascaded
application, you should ignore step 3, 4 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 for a total maximum daisy-chain cable length
30M and a maximum total of 256 computers connected.
Note that any daisy-chaining attempt to go beyond 30M will
suffer trade-off of video degradation as depending on the cable
quality.

Step 3. Use the daisy-chain cable (M-HDB15-HDB15-F) to

connect the Daisy Chain-OUT port (HDB 15 female)
of the master KVM Switch to the Daisy Chain-IN port
(HDB 15 male) of the second KVM switch. Connect
the provided AC power adapter to the second KVM
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 daisy­chain up to 16 levels of KVM switches. Plug a
terminator onto the Daisy Chain-Out port of the last
daisy-chained KVM switch unit.

Daisy-chain cable Terminator

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 KVM switch(es). You should use our
special USB PS/2 KVM combo cable for connection to
a USB computer (PS/2 computer).

Connect USB and VGA
connectors to computer.

Connect PS/2 keyboard, VGA,
and USB with USB-to-PS/2
adapter to computer.

Special integrated USB & PS/2 KVM combo cable

The special KVM cable provides a PS/2 keyboard connector,
a USB connector and a HDB video connector for 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 a USB-to­PS/2 adapter to the USB connector and you’ll have a PS/2
connector for mouse. Do not connect both USB connector

without adapter and PS/2 connector to a computer at
the same time.

Step 6. Power up the connected computer. After your

computer is powered up the keyboard and mouse will be
recognized and now you can begin operating the switch.

Step 7. Repeat step 5 and 6 for the remaining computers.

Easy Operation

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.

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.

Notes:

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. For detailed OSD function, please refer to previous OSD Menu section.

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.
