Hardware Installation

1. Connect up to three monitor(s) into the Console's DVI connectors; plug a USB keyboard and a USB mouse into the dedicated USB keyboard and mouse ports on the KVM switch. If using audio, also connect speakers with 3.5mm mini-jack plugs.

2. Use male-to-male DVI video cable(s) to connect the DVI connector(s) on the computer's video card, to the DVI ports for one of the KVM's PC ports (i.e. PC1).

NOTE: Do not mix different types of DVI cables (DVI-I, DVI-D) on the same KVM.

1. 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 2, and the USB port on the computer (type A, flat connector). If using audio, connect 3.5mm mini-jack cables from the PC port to the sound card.

NOTE: DVI + USB + Audio KVM combo cables are also available which can be used in place of separate individual cables (e.g. StarTech.com ID: DVI4N1USB6).

1. Repeat Steps 2 and 3 for each PC port on the KVM switch, or each computer you wish to use on the KVM.

2. OPTIONAL: Connect any other USB peripheral you wish to share between the connected computers/devices to the extra USB Hub port on the Console side.

3. Connect the external power adapter from a wall outlet to the power connector on the rear panel of the KVM switch.

4. Power up the first computer/device and wait for it to fully boot and test keyboard/mouse functionality.

5. Once operation has been successfully confirmed, switch to the next port and power up that computer/device and confirm.

6. Once completed for all computers/devices connected to the KVM switch, you should be able to switch between ports freely.

Driver Installation

No driver installation is required for the KVM switch, as the keyboard/mouse use USB drivers that are already installed on any operating system that fully supports USB.

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

For 2 Port model, each push of the Selection Button on the front of the KVM switch will immediately switch between the two ports on the KVM switch.

For 4 Port model, each push of the Selection Button on the front of the KVM switch will immediately switch to the selected computer.

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. (4 port model only)

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.

Scan Time

Four options are available for users to set the Scan Time duration, which includes 3, 8, 15 and 30 seconds.

To change the Scan Time interval, press both front panel buttons "1" and "2" simultaneously. The unit beeps 1, 2, 3 or 4 times for Scan Time of 3, 8, 15 or 30 seconds respectively. (4 port model only)

NOTE: Scan Time is automatically set to the default of 3 seconds when the units loses power.

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 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 and press twice, then release followed by pressing left once, which will enable / disable the hotkey feature.

To select a computer:

$$ \text { Left } < \text { CTRL } > + \text { Left } < \text { CTRL } > + < 1 > $$

(Example: Selects the computer at port 1.)

$$ \text { Left } < \text { CTRL } > + \text { Left } < \text { CTRL } > + < 2 > $$

(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 fixed time interval (see Scan Time below).

To start Auto Scan:

$$ \text { Left } < \text { CTRL } > + \text { Left } < \text { CTRL } > + < \text { F1 } > $$

To abort the Auto Scan mode, press the left key twice. When Auto Scan detects any keyboard or mouse 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.

$$ \text { Left } < \text { CTRL } > + \text { Left } < \text { CTRL } > + < \text { F2 } > $$

To select the previous or the next computer, press or 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 Time, set the scan time of duration before switching to the next computer:

$$ \text { Left } < \text { CTRL } > + \text { Left } < \text { CTRL } > + < \text { F3 } > $$

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

Adjust Video Signal (for 4 port model only)

The video signal can be optimized to the length or quality of your DVI cable. Only perform this operation if you are experiencing video quality issues.

Step 1. Press the "FUNC" button 3 times. The "POWER" LED will start flashing.

Step 2. The settings are adjusted by pressing the numbered buttons on the front of the KVM.

A) Button "1" Adjusts the EQUALIZATION of the video source. 1 Beep is normal, 2 beeps is enhanced.
B) Button "3" Adjusts the output CURRENT of the video source. 1 Beep is normal, 2 beeps is enhanced.
C) Button "4" Adjusts the AMPLIFICATION of the video source. 1 Beep is normal, 2 beeps is low, 3 beeps is medium, 4 beeps is high.

Step 3. Press the same "FUNC" button from Step 1 to exit.

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.

$$ \text { Left } < \text { CTRL } > + \text { Left } < \text { CTRL } > + < \text { F5 } > $$

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:

$$ \text { Left } < \text { CTRL } > + \text { Left } < \text { CTRL } > + < \text { A } > $$

Alternative Hotkey Commands

In addition to the Left + Left hotkeys, there are two alternative hotkey sequences available.

1. For the following operations, users may press twice instead of pressing left twice.

To select a computer:

$$ < \text { ScrollLock } > + < \text { ScrollLock } > + < 1 > $$

(Example: Select the computer at port 1.)

$$ < \text { ScrollLock } > + < \text { ScrollLock } > + < 2 > $$

(Example: Select the computer at port 2.)

NOTE: Do not use the keypad at the right of the keyboard.

1. For those keyboards that do not have or support , please press and HOLD the Left and press twice instead of pressing Left twice.

To select a computer:

$$ \begin{array}{l} \text {Hold Left < SHIFT > + Press < NumLock> + Press < NumLock>} \ \text {then release < SHIFT > + Press < 1 >} \end{array} $$

(Example: Select the computer at port 1.)

$$ \begin{array}{c} \text {Hold Left < SHIFT > + Press < NumLock> + Press < NumLock>} \ \text {then release < SHIFT > + Press < 2 >} \end{array} $$

(Example: Select the computer at port 2.)

NOTE: Do not use the keypad at the right of the keyboard.

Change Leading Hotkey

The default leading hotkey sequence involves pressing the left twice in succession (e.g. left + left ). This can be changed to the right key instead, to avoid accidental activation due to using the left key for functions such as Copy/Paste.

To change the leading hotkey sequence to Right :

$$ \text { Left } < \text { CTRL } > + \text { Left } < \text { CTRL } > + \text { hold } < \text { ALT } > + \text { press Right } < \text { CTRL } > $$

All hotkey commands that previously required pressing the Left will be switched to requiring the right instead.

To change the leading hotkey sequence back to Left :

$$ \text { Right } < \text { CTRL } > + \text { Right } < \text { CTRL } > + \text { hold } < \text { ALT } > + \text { press Left } < \text { CTRL } > $$
