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-411KA 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-411KA unit must be
powered-up. But before powering the NS-411KA 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.
Video
The image on my monitor is not clear.
6 Please verify that all video cables are inserted properly.
6 It may be that your resolution or refresh rate is too high. Try a
lower refresh rate, or try lowering the resolution.
6 Your video cable may be too long. Video signals are high
frequency signals and are therefore subject to interference.
Please use video cables that are as short as possible.
6 Make sure that the power adapter is plugged into the mains and
that it is working correctly. Its rating must be DC9V 600mA.
Audio and Microphone
I have connected the speakers to the KVM and I am not getting any sound
from my computer.
6 Check that the sound is enabled on the computer by going into
the system setting.
6 Checkthatthevolumeisturnedupinyoursound configuration.
6 Make sure that the audio cable is connected properly and
connected to the appropriate connector.
6 Check that the speakers you are using are functioning properly.
