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. 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.
Console Connection
Before installation, make sure all devices and computers to be connected to the StarView switch
have been turned o. 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 gure 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
