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
