Instruction Manual 5

Operation

Front Panel

On-line LED / Selected LED

When the LED turns green, the connected computer is powered-on. When a computer is

selected, its corresponding red LED illuminates.

Push Buttons

Pressing the “Select” button switches between ports.

HotKey Control

A Hotkey command is a short keyboard sequence for selecting a computer, activating computer

scan, etc. A hotkey sequence starts with two left <CTRL> keystrokes (successively within 0.2

seconds) followed by one or two more keystrokes. A built-in tone generator creates a high-pitch

beep for correct hotkey command; otherwise, one low-pitch beep is generated for errors and the

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

NOTE: Press and hold Left <SHIFT> and press <NumLock> twice, then release <SHIFT> followed

by pressing left <CTRL> once, which will enable / disable the hotkey feature.

To select a computer:

Left <CTRL> + Left <CTRL> + <1>

(Example: Selects the computer at port 1.)

Left <CTRL> + Left <CTRL> + <2>

(Example: Selects the computer at port 2.)

NOTE: Do not use the keypad on the right-side of the keyboard.

Auto Scan

The KVM automatically scans through the powered-on computers in sequence on a xed time

interval (see Scan Time below).

Instruction Manual 6

To start Auto Scan:

Left <CTRL> + Left <CTRL> + <F1>

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

keyboard activity, it suspends the scanning till the activity stops; it then resumes with the next

computer in sequence. The length of the Auto Scan interval (Scan Time) is adjustable, see below.

Manual Scan allows users to manually switch back and forth between powered-on computers.

Left <CTRL> + Left <CTRL> + <F2>

To select the previous or the next computer, press <UP> or <DOWN> arrow keys. To abort the

Manual Scan, press any other key.

Scan Time

Four options are available for users to set the Scan Time duration, it Includes 3, 8, 15 and 30

seconds.

Note: Scan Time is set to 3 seconds by default.

To adjust Scan Rate, set the scan time of duration before switching to the next computer:

Left <CTRL> + Left <CTRL> + <F3>

The KVM Switch generates 1 to 4 beeps indicating a scan time duration for 3, 8, 15 or 30 seconds

respectively.

Audio Lock

There are two options for Audio Lock: ON and OFF.

When ON, audio selection follows computer selection. When OFF, audio selection stops

following computer selection. It is useful if you want to listen to a particular computer’s audio

signal while operating other computers.

Left <CTRL> + Left <CTRL> + <F5>

The KVM switch beeps once or twice corresponding to ON and OFF respectively.

To change which computer port the audio stays on to the currently selected port, press the

following hotkey:

Left <CTRL> + Left <CTRL> + <A>

Instruction Manual 7

USB-Port Rule

There are two settings for USB-Port Rule: ON or OFF.

When set to ‘ON’, the USB Hub ports follows computer selection.

When set to ‘OFF’, the USB Hub ports stays on the currently selected PC port.

Press the hotkey below to turn ON/OFF the USB-Port Rule:

Left <CTRL> + Left <CTRL> + <F7>

To change the PC port that the USB hub stays on to the currently selected PC port, press the

following hotkey:

Left <CTRL> + Left <CTRL> + <U>

NOTE: Please make sure that installation of the USB device has been accomplished before

switching to the next computer.

Change Leading Hotkey

The default leading hotkey sequence involves pressing the left <CTRL> twice in succession

(e.g. left <CTRL> + left <CTRL>). This can be changed to the right <CTRL> key instead, to avoid

accidental activation due to using the left <CTRL> key for functions such as Copy/Paste.

To change the leading hotkey sequence to Right <CTRL>:

Left <CTRL> + Left <CTRL> + hold <ALT> + press Right <CTRL>

All hotkey commands that previously required pressing the Left <CTRL> will be switched to

requiring the right <CTRL> instead.

To change the leading hotkey sequence back to Left <CTRL>:

Right <CTRL> + Right <CTRL> + hold <ALT> + press Left <CTRL>
