entering hotkey commands. The SV431H switch provides the easiest way to manage multiple

USB or PS/2 computers with one PS/2 keyboard, mouse and monitor. No more tangled cables

and messy working environments

Instruction Manual 2

Installation

PC BIOS Notice

The following BIOS setup changes are necessary for PC users using USB and not necessary for

Mac users:

1. In STANDARD CMOS, set HALT ON ERROR to ALL BUT KEYBOARD.

2. In PNP AN PCI SETUP, set PNP OS INSTALLED to YES and set USB IRQ to ENABLE.

3. For newer computers: in INTEGRATED PERIPHERALS, set USB CONTROLLER and KEYBOARD

SUPPORT to ENABLE.

Also make sure that USB is properly selected in Device Manager under Control Panel, as shown

below.

Note: The SV431H is applicable for USB keyboard and mouse. Switching from one computer

to the next is equivalent to unplugging the USB device from one computer and plugging it to

another. Some USB drivers check attached USB peripherals all the time and do not accept plug-

n-play function.

Instruction Manual 3

Adhesive Rubber Feet

For desktop operation, you may stick the four round rubber feet (supplied with the unit) to the

bottom of the StarView. Do not use the rubber feet with the rack mount option.

Console Connection

Before installation make sure all devices and computers to be connected to the SV431H have

been turned o.

Plug you monitor to the consoles VGA port; connect the PS/2 mouse and keyboard to the

console port marked with a mouse and a keyboard as shown in gure below.

Computer Connection

Use a HDB15 male-to-female cable to connect from your computers VGA port to the SV431H

VGA port as shown on the following page.

For USB computers: Use a USB A-B cable to connect from one of the SV431H PC ports to the USB

port on the corresponding computer (series A connector), as shown on the following page.

Instruction Manual 4

For PS/2 computers: Connect a PS/2 Y-adapter, which comes with the unit, to the SV431H PS/2,

then use two mini-DIN6 male-to-male cables for keyboard and mouse, see gure below. There

are two mini-DIN6 female connectors on the PS/2 Y-adapter marked as keyboard and mouse. Be

sure not to swap the connections.

Instruction Manual 5

For notebook computers: In most cases, all you need is one PS/2 male-to-male cable connected

between the SV431H and your Notebook; the Y-adapter is not necessary. However, some

Notebook computers do not follow industry-standard, please check your Notebook users

manual for details.

You can now turn on all devices and computers.

Note: Do use both PS/2 and USB of a PC port on the SV431H at the same time. Only the USB port

will eective if this occurs.

Operations

Front Panel

• Online 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

Each computer has a button associated with it on the front panel for selection.

• K/M Reset

K/M Reset solves most problems developed by keyboard, mouse, device replacement or change

of conguration. Press both of the front-panel number 1 and 2 push buttons for 2 seconds to

re-congure the whole system without turning either the SV431H or any computer o.

• Auto Scan

Auto Scan automatically scans through computers one by one in a xed intervals. The SV431H

provides an easy to use feature to start Auto Scanning. You can press down both the front-panel

number 3 and 4 buttons for 2 seconds to start Auto Scanning.

Note: Computers using a USB keyboard and mouse are not immediately operable when selected

during Auto Scan. Wait for about three seconds after switching to a USB computer, then use the

keyboard and mouse.

Instruction Manual 6

Hot Key Commands

Hot Key commands are short keyboard sequences used to select a computer, to activate

computer scan, etc. The SV431H interprets keyboard strokes for Hot Keys all the time. A Hot Key

sequence starts with 2 left Ctrl keystrokes followed by 1 or 2 more key strokes. A built-in buzzer

generates a high-pitch beep for correct hot key commands; otherwise, one low-pitch beep for an

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

L-Ctrl: is the Ctrl key located at the left side of the keyboard.

1~4: are the numbers 1 ~ 4 at 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 address, which is

determined by the SV431H connection at the back.

Left Ctrl + Left Ctrl + 4

Selects a computer connected to the PC port 4.

• To start Auto Scan, which will automatically scan power-on computers one by one at a xed

interval:

Left Ctrl + Left Ctrl + F1

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

stops; it then resumes with the next computer in sequence. The length of the Auto Scan interval

(Scan Rate) is adjustable. To abort the Auto Scan mode, press the left Ctrl key twice.

• Manual Scan enables you to manually switch back and forth between power-on computers.

Left Ctrl + Left Ctrl + F2

Press á or â to select the previous or the next computer in sequence. Press any other key to

abort the Manual Scan.

• To adjust the Scan Rate which sets the duration before switching to the next computer in

Auto Scan:

Left Ctrl + Left Ctrl + F3

The SV431H sends one to four beeps indicating scan intervals of 3, 8, 15 and 30 seconds

respectively.

• To adjust keyboard typematic rate (characters/sec), this setting over-rides that of the BIOS

and any operating system:

Left Ctrl + Left Ctrl + F4

The Sv431H generates 1 to 4 beeps corresponding to 10, 15, 20 and 30 characters/sec

respectively.

Instruction Manual 7

Cascade Conguration

Connection

Before connecting a device (a computer or any other SV431H) to the master under power, you

must turn o the devices. Only the PS/2 ports are operable for cascade operation.

Computer Selection by Hot Key Command

The rst digit is the port address of the Master unit (1~4) and the second digit is the port address

of the Slave (1~4). Please note that only the Master’s PS/2 ports can be connected to a Slaves

Console port.

Left Ctrl + Left Ctrl + 1 + 3

Selects a computer connected to PS/2 port 3 of a Slave connected to PS/2 port 1 of the Master.

Change Leading Hot Key

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
