Troubleshooting
Keyboard
My keyboard is not detected, or a keyboard error is given
during boot-up.
6
Please verify that the keyboard cables are inserted properly.
6
Check to make sure that power cord is plugged in and is
working properly.
The computers all boot up properly, but the keyboard is
not functional.
6
Make sure the keyboard is plugged into the converter unit
properly.
6
Verify that the keyboard works when plugged into the
computer directly. (You will have to shut down your
computer first to do this).
6
Try using a different keyboard.
6
Make sure that the power adapter is plugged into the mains
and that it is working correctly. Its rating must be 9V 600mA.
Mouse
My mouse is not detected during boot up.
6
Please verify that all mouse cables are inserted properly.
Check especially for a mix-up with the PS/2 keyboard cable,
they have the same kind of connector and are therefore
easily confused.
6
Read your motherboard documentation and make sure that
the PS/2 mouse IRQ is enabled. (This can for most
computers be set in the BIOS setup pages)
The computers boot properly but I can not use the mouse.
6
Please verify that the mouse is plugged into the converter
NS-211KA unit properly.
6
Make sure the mouse works proper when plugged into a
computer directly, you will need to reboot the system to test
this.
6
Try using a different mouse.
6
Verify that the mouse complies with the PS/2 standard. A
combination mouse will work, but it must be set to PS/2
mode and the correct serial mouse to PS/2 adapter must be
used. A serial mouse with a serial - PS/2 adapter will not
work, since
the
mouse signals do not comply with the PS/2
standard.
6
Make sure that the power adapter is plugged into the mains
and that it is working correctly. Its rating must be 9V 600mA.
When I switch between computers mouse movement
becomes random.
6
Verify that your computers do not have more than one
mouse driver installed. Make sure that the driver is for a
standard PS/2 or Microsoft compatible PS/2 mouse. Also
check with the mouse vendor to verify you are using the
latest mouse driver.
6
Check your config.sys and autoexec.bat files (if you run
Windows that is) and verify that only one mouse driver is
loaded.
6
If a special mouse is used, such as cordless or scrolling
mice, make sure you use generic PS/2 mouse drivers. A
non-standard PS/2 mouse may have extensions on the
PS/2 protocol that are not supported by the NS-211KA unit.
6
Do not move the mouse or press any mouse buttons while
switching from one system to the other.
6
Try resetting the mouse by unplugging it from the NS-
211KA unit for about 3 seconds. Now mouse movement will
be correct again.
6
Before booting up any PCs, the NS-211KA unit must be
powered-up. But before powering the NS-211KA unit up,
the mouse and keyboard must be connected first. Any
deviation from this power-up sequence may lead to erratic
behavior of the systems.
