Installation

Hardware Installation

WARNING: Prior to installation, please ensure that all of the computers and

the KVM switch are powered down.

Console Connection

The KVM switch is designed to use USB console connections only. A USB

compatible keyboard and mouse and DVI/HDMI* monitor must be used for

the local console.

NOTE: DVI to HDMI adapters sold separately.

Plug a monitor into the Console’s DVI connector; plug a USB keyboard and a

USB mouse into the dedicated USB keyboard and mouse ports on the KVM

switch. Ensure the keyboard/mouse are connected to the proper connectors.

Connecting Computer to the KVM Switch

To connect a computer to the KVM switch, use the appropriate DVI/USB

KVM cable (or separate cables) to connect from one of the PC ports located

on the rear panel of the KVM switch to the USB and DVI video ports on the

computer.

1.Use a male-to-male DVI video cable to connect the DVI connector on the

computer’s video card, to one of the KVM’s PC ports (i.e. PC1).

2.Use a USB type A-B Cable to connect the KVM’s USB port (type B,

square connector) for the PC port used in Step 1, and the USB port on the

computer (type A, ﬂat connector).

3.Repeat for Steps 1 and 2 for each PC port on the KVM switch, or each

computer you wish to use on the KVM.

4.Connect the power cord from the KVM to an AC power outlet.

5.Turn the monitor on ﬁrst, followed by the KVM switch via the power switch

on the rear panel.

6.Power up the ﬁrst computer/device and wait for it to fully boot and test

keyboard/mouse functionality.

7.Once operation has been successfully conﬁrmed, switch to the next port

and power up that computer/device and conﬁrm.

Operation

Front Panel

Port Selection/Link LED

The LED turns green when the connected computer is powered-on. The

corresponding LED will also illuminate red when that PC port is currently

selected.

Port Selection Button

Each push button on the front panel corresponds with a PC port. Pressing

the button will immediately select that port.

K/M Reset

K/M Reset resolves the majority of problems developed by keyboard

and/or mouse device replacement or conﬁguration changes. Press

down buttons 1 and 2 simultaneously for 2 seconds to reconﬁgure the

whole system without having to turn off the KVM switch or any attached

computers.

Auto Scan

The KVM automatically scans through the powered-on computers in

sequence on a ﬁxed time interval (see Scan Time below).

To activate Auto Scan, press down front panel push buttons “3” and “4”

simultaneously. The port LED ﬂashes during Auto Scan. Auto Scan is

effective for powered-on computers only. To exit the Auto Scan mode, just

tap any one of the push buttons.

NOTE: When Auto Scan detects any keyboard activity, it suspends the

scanning until the activity stops; it then resumes with the next computer in

sequence. The length of the Auto Scan interval (Scan Rate) is adjustable,

see below.

Hot-key commands

A Hot-key command is a short keyboard sequence for selecting a computer,

activating computer scan, etc. A hot-key sequence starts with two left

<CTRL> keystrokes (successively within 0.2 seconds) followed by one or

two more keystrokes. A high-pitch beep will be generated for each correct

hot-key command; otherwise, one low-pitch beep is generated for errors and

the bad key sequence will not be forwarded to the selected computer.

NOTE: Left <CTRL>: refers to the Control key on the left side of the

keyboard.

1~8: refers to the number keys ‘1’~’8’ in the upper row of the keyboard. Do

not use the keypad at the right of the keyboard.

To select a computer by hot-key command, you must know its port number,

which is determined by the KVM switch connections.

EXAMPLES:

Left <CTRL> , Left <CTRL>, 7 : Selects a computer connected to PC port

7 on the KVM switch.

Auto Scan

In this mode, the KVM Switch automatically switches from one power-on

computer to the next, sequentially, at a ﬁxed interval.

Left <CTRL>, Left <CTRL>, F1

When Auto Scan detects any keyboard or mouse activity, it suspends the

scanning until the activity stops. It then resumes with the next computer in

sequence. The length of the Auto Scan interval (Scan Time) is adjustable.

To abort Auto Scan mode, press the left <CTRL> key twice.

Manual Scan

Enables you to manually switch back and forth between the powered

computers:

Left <CTRL>, left <CTRL>, F2

Press the <UP> arrow key to select the previous computer and the

<DOWN> arrow key to select the next computer. Press any other key to

abort Manual Scan mode.

Scan Time

To adjust Scan Time, which sets the duration before switching to the next

computer in Auto Scan:

Left <CTRL>, Left <CTRL>, F3

The switch will beep one to four times indicating the scan interval of 3, 8,

15 and 30 seconds respectively.
