TROUBLESHOOTING

Note: If you are experiencing difficulties, first make sure that there are no problems with
the cables and make sure they are all properly connected.
IBM PC or Compatible:
PC cannot find keyboard or mouse after the boot process. Please make sure you
turn on your PC system by the PC port in order to boot Windows O.S. and for
your system to identify the keyboard and mouse type before you install this USB
KVM switch.
Keyboard or mouse does not work with or is not compatible with the PC. Please,
make sure the keyboard or mouse works when it is plugged directly into a
computer. If the problem persists, please try another keyboard or mouse.
Mouse doesn't not work in Auto Scan mode. You can press any key on the
keyboard or the front button on the face plate to return to standard mode and then
use the keyboard or mouse again.
When KVM switch is in Auto Scan mode, there are only VGA monitor display
and CPU alternately, but the USB Hub does not switch to Auto Scan mode: After
you press any key, the PC port will be selected the same time you see the current
PC Screen.
If a keyboard error message appears on your screen, this means the PC BIOS need
to be setup. Please refer to the Hardware Installation Procedure or upgrade to the
new BIOS, so it will accept the USB to PS2 conversion. In most cases, during the
PC boot process, most BIOS support USB to PS2 keyboard conversion or USB
keyboard.
For 4D and 5D users, it is recommended to work with a USB hub port of the USB
KVM switch (only if the mouse supports USB type). Because the USB
conversion standard does not define PS2 to USB converters for 4D or 5D mice,
these extra user-defined keys will lose function when users use the PS2 port of the
USB switch.
The recommended VGA cable distance is 5 meters maximum without ghosting
and degrading. Normally, the cable length is based on the driver capacity of your
VGA card. If you need longer VGA cables, please use VGA extenders to
accomplish your applictions.
