*installation pictures are representations only

1. Plug a monitor into the Console’s DisplayPort connector; 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 and/or a microphone with 3.5mm mini-jack plugs.

2. Use a male-to-male DisplayPort video cable to connect the

DisplayPort connector on the computer’s video card, to one of the

KVM’s PC ports (i.e. PC1)

3. 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 computer sound

card.

NOTE: A DisplayPort + USB + Audio KVM combo cable is also

available which can be used in place of separate individual cables,

StarTech.com ID: DP4N1USB6.

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

each computer you wish to use on the KVM.

5. OPTIONAL: Connect any other USB peripherals you wish to share

between the connected computers/devices to the extra USB Hub

ports on the Console side.

6. Connect the external power adapter from a wall outlet to the power

connector on the rear panel of the KVM switch. The Power LED

should light up solid and/or the LED for the selected PC port.

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

test keyboard/mouse functionality.

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

port and power up that computer/device and conﬁrm.

9. 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

and mouse use generic USB keyboard/mouse 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

2-Port: Pressing the front panel “Select” button will toggle between the

two ports on the KVM switch.

4-Port: Each push button on the front panel corresponds with a PC

port. Pressing that button will immediately select that port.

AutoScan

The system automatically scans through the power-on computers in

sequence with a ﬁxed interval (see Scan Time below).

4-Port:To activate AutoScan, press front panel push buttons “3” and

“4” simultaneously. The port selection LED will ﬂash during

AutoScan. AutoScan will select active computers only. To exit

AutoScan mode, just press any one of the front panel push

buttons.

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.

4-Port:To change the Scan Time, press front panel buttons “1” and “2”

simultaneously. The unit will respond with beep(s) of 1, 2, 3 or

4 times for a Scan Time of 3, 8, 15 or 30 seconds respectively.

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 ﬁxed time interval (see Scan Time below).

Note: The keyboard and mouse are not operable during Auto Scan.

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 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.

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.
