Introduction

Overview

The StarView SV231USB and SV431USB, fully

compatible with USB specifications, are a combination of

USB KVM (Keyboard/Video/Mouse) switches and USB

peripherals sharing devices. With the SV231USB and

SV431USB, you can easily operate up to 2 or 4 PCs,

G3/G4 Macs, or iMacs respectively from the 1 USB

keyboard, 1 USB mouse, and 1 monitor saving you

space, time, equipment and money. Its peripheral

sharing function enables you to share more USB

peripherals among all computers.

Installation is easy as connecting USB A-B cables to the

computers and to the StarView switch. Computer

selecting is as easy as front panel button pressing. The

built-in USB hub ensures smooth switching from one

computer to the other. The StarView switches provide the

easiest way to manage multiple computers with USB

interface and share USB peripherals among computers.

Installation

PC BIOS Notice

The following BIOS setup changes are necessary for

PC users and not necessary for Mac users:

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

BUT KEYBOARD

2. 2. In PNP and PCI SETUP, set PNP OS

ONSTALLED to YES and set USB IRQ to ENABLED

Note: The StarView switch is applicable for USB

keyboard and mouse switching from one computer

to the other. If you plan to share other peripherals

such as a CCD camera, printer or scanner, it is

necessary to shut down the driver of the computer

before switching to another computer. Because port

switching is equivalent to unplugging the USB cable

from one computer and plugging it into another one,

some USB drivers check attached USB peripherals

all the time and do not accept plug-n-play functions.

Console Connection

Before installation, make sure all devices and computers

to be connected to the StarView switch have been

turned off.

Plug a monitor to the Console’s VGA port; plug a USB

keyboard and a USB mouse to any two of the Console’s

USB ports as shown in figure 2.

For SV431USB only: As an option, the Master

StarView is either SV431 or SV431D to be linked to

the SV431USB with a mini-DIN8 male-to-male cable.

The SV431USB can operate as USB-peripheral

sharing devices

Computer Connection

Use a HDB15 male-to-female cable to connect from a

computer’s VGA port to the StarView’s VGA port of the

PC side, as shown in figure 3.

Use a USB A-B cable to connect from the StarView’s

USB port on the corresponding computer (A connector is

the flat connector) as shown in figure 3.
