Instruction Manual

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

ENABLED Note: The StarView switch is applicable for USB 2.0 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.

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 2.0

keyboard and a USB 2.0 mouse 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 2.0 peripheral sharing devices
