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

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
