Installation

1. Plug your keyboard and mouse into the correct USB ports on the side of the switch. If using a

wireless keyboard and mouse whose receiver has only one USB plug, make sure it is inserted into
the keyboard port and not the mouse port.

2. Plug your monitor into the VGA port on the side of the switch.

3. Plug your powered speakers into the audio jack on the side of the switch.

4. Plug the extra KVM cables into the green ports on the back of the switch using the custom green

connectors. (You may skip both or only one of these cables if only using two or three computers)

5. Plug the VGA, USB, and audio connections on each of the KVM cables into each of your

computers.

Operation

Switching between computers (Toggle keys)

By default, all of the following commands begin by pressing the [Scroll Lock] key twice. A few PC key­boards and all Apple keyboards do not have a [Scroll Lock] key. If you have one of these keyboards you
must use the alternate toggle key of [Control] instead. Enter advanced hotkey mode as described in the
next section and press [T]. Then all of the following commands will work by simply pressing the [Control]
key in place of the [Scroll Lock] key.

[Scroll Lock] [Scroll Lock] [Enter]

This will switch everything (KVM and sound) to the next port.

[Scroll Lock] [Scroll Lock] (number) [Enter]

This will switch everything (KVM and sound) to the exact port number typed. The number must be be­tween 1 and 4, and you must use the numbers across the top of the keyboard, not the number pad. This
command will work even if the computer on that port is not powered on.

8

[Scroll Lock] [Scroll Lock] [a] [Enter]

This will start the Auto Scan mode, the KVM focus cycles from port to port at a 5 second interval.

[Scroll Lock] [Scroll Lock] [a] [n] [Enter]

This will start the Auto Scan mode, the KVM focus cycles from port to port at a [n] second interval.

To exit Auto Scan mode, press [Esc] or [Spacebar].

9

Advanced Hotkeys

You may enter advanced hotkey mode by pressing and holding [Num Lock] on the number pad, then
pressing the [-] key on the number pad and immediately releasing both keys. On Apple keyboards the
[Clear] key on the number pad should be used in place of [Num Lock]. If you have done this correctly the
Caps Lock and Scroll Lock lights on the keyboard should begin ashing. This means you are in hotkey
mode, which will be shortened to just [HKM] below. If you are having trouble entering hotkey mode press
[Esc] and try again.

Please read the following pages to learn how to use advanced hot keys to change the keyboard into Mac
mode or Sun mode, in order to use the special keys on Mac and Sun keyboards.

[HKM] [T] – This will change the toggle key used to switch between computers. Each time you enter this

command the toggle key will switch between the default of [Scroll Lock] and the alternate of [Control].

[HKM] [H] – This will change the hotkey used to enter hotkey mode. Each time you enter this command

the keys used to enter HKM will switch between the default of [Num Lock]+[-] and the alternate of
[Control]+[F12]. Please note that you must hold [Control] while pressing [F12] in exactly the same way you
must hold [Num Lock] while pressing [-].

[HKM] [F2] – This will manually set the operating system of the currently active port to Macintosh. This
will allow the KVM to emulate special keys that are normally only present on an Apple keyboard.

[HKM] [F3] – This will manually set the operating system of the currently active port to Sun. This will
allow the KVM to emulate special keys that are normally only present on a Sun keyboard. On some Sun
computers it is necessary to set up the KVM in this way before the system will properly boot up.

[HKM] [F10] – This will set the operating system of the currently active port to Automatic. The KVM will
auto-detect the type of computer on that port to allow emulation of whatever keys are most appropriate to

that computer. This is the default setting for all ports and is appropriate for PC systems.

13

[HKM] [F4] – This will type out a list of current KVM settings. Open a word processor before using this
command in order to see how the KVM is congured.

[HKM] [F5] – This will reset the USB ports on the switch, and may clear up any keyboard or mouse
problems.

[HKM] [R] [Enter] – This will reset all KVM settings to their defaults.
