BRIEF INTRODUCTION

The KVM Switch allows you to control several sets of personal computers by a keyboard, a mouse

and a monitor. In the meantime, you just need to connect the cable and turn on the power to

control up to 256 sets of personal computers without installing any additional interface card or

software.

Easy Installation

The 3-in-1 CPU Connector (VGA, Keyboard and Mouse) can save the installation time and space

and assure the correct signals. The universal AC power input of 100~240VAC, 50Hz~60Hz saves

you the trouble of finding the space for installing the Power Adaptor. You can install a cascade to

facilitate expansions or transportation without requiring a cascade cable or changing the KVM

configurations.

On-Screen Display (OSD) Menu

The embedded OSD control module lets you name the PC and KVM and modify the KVM

configuration, and the security mode can prevent others from turning on the KVM by mistake and

switching the linked PC from the OSD. Most conveniently, the OSD not only supports keyboard

operations, but also supports mouse clicking.

Enhanced Video Quality

The special video circuit design supports resolution up to 1280x1024, 75Hz, and also keeps the

same quality under the Cascade architecture.

If a port is connected to KVM, then the red light of that port will not on.

Besides the special mode, the whole system architecture only has one red light (indicating that

the Console is connecting to the PC) or has no red light (when powering on the KVM for the

first time.)

INSTALLATION

Standalone

1. Make sure that the power switch at the rear panel of the KVM is OFF. Plug an end of the AC

power cord into the KVM and the other end to an AC power supply.

2. Make sure to power off the PC and then install the 3-in-1 cable to each of the PC one by one.

Note: If the ON-LINE LED (Green) of any port of a PC is on, then we recommend you to

power off such PC (Turn off the power switch of the power supply of the PC or unplug the

power cable of the PC) or wait till Step 4 to install that particular PC.

3. Turn on the power switch at the rear panel of the KVM.

4. Power on the PC.

Note:

It is not necessary to power down the whole system for install a new PC or KVM thereafter.

All you need is to make sure that the new PC or KVM is OFF during the installation. If the

KVM powers down due to external factors (such as power failure or the power of the KVM is

turned off), we recommend you to reinstall the whole system.

Connection in Series

1. Make sure that the power switch at the rear panel of the Master KVM is OFF. Plug one end

of the AC power cord to the KVM and the other end to the AC power supply.

2. Make sure the power switches at the rear panels of all slave KVMs are OFF. Plug one end

of the AC power cord to the KVM and the other end to the AC power supply.

3. Install the Master KVM to the 3-in-1 cable (same as the cable for connecting the KVM to the

PC) in the middle of the Slave KVMs.

4. Make sure the power of the PC is OFF and then install the 3-in-1 cable to each PC one by

one.

Note: Install the PCs on the master or the PCs on the Slave first. If the ON-LINE LED (Green)

of any port of a PC is on, then we recommend you to power off such PC (Turn off the power

switch of the power supply of the PC or unplug the power cable of the PC) or wait till Step 7

to install that particular PC.

5. Turn on the power switch at the rear panel of the master KVM.

6. Turn on the power switch at the rear panel of the slaver KVM.

7. Power on the PC.

Note: It is not necessary to power down the whole system for install a new PC or KVM

thereafter. All you need is to make sure that the new PC or KVM is OFF during the

installation. If the KVM powers down due to external factors (such as power failure or the

power of the KVM is turned off), we recommend you to reinstall the whole system.

Note:

It is noteworthy that there are two levels available.

Expansion

1. PCs

It is not necessary to power down the KVM or other computer connected to the KVM system.

You only need to power off the desired PC and connect the PC to the CPU port of the KVM

in parallel by the 3-in-1 cable, and then power on the PC.

2. Slave KVM

Make sure the power switch at the rear panel of the KVM is OFF. Use the AC power cord

(3-in-1 cable) to connect the console port of the slave KVM to the CPU port of the master

KVM. Power on the slave KVM.

For example:

If you want to install one Slave KVM and three PCs, then just follow Step 2 of the foregoing method

to add the slave KVM and install the PCs one by one according to Step 1.
