Specifications

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 DC9V 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)
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-411K 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 KVM4C unit for
about 3 seconds. Now mouse movement will be correct again.
6 Before booting up any PCs, the NS-411K unit must be powered-
up. But before powering the NS-411K 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.
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 the power cord is plugged in and is
working roperly.
The computers all boot up properly, but the keyboard is not functional.
6 Make sure the keyboard is plugged into the NS-411K 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 DC9V, 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 NS-411K unit
