Troubleshooting
If none of the LED displays on the KVM Switch are illuminated, please check that the power
adapter is connected and switched on at the mains.
Before you check any further please make sure that all cables are well connected!
KVM Switch Troubleshooting
If the KVM Switch reacts to keyboard input from the SCROLL LOCK key with a beep signal but
you get no monitor picture displayed please check if the currently selected computer is in sleep
mode or powered down. You can try to wake up this computer by pressing the ESCAPE key
several times until the CPU Switch no longer beeps, and then pressing spacebar or RETURN
key to wake up the computer. The P16-IP supports VGA power save modes and suspends the
monitor signal if the currently selected computer has switched off the VGA signal.
Please check if your problems can be solved by resetting the CPU switch, via the push buttons
on the front panel. For cascaded systems please follow the procedures mentioned in the
CASCADING section.
1. The Monitor picture is not sharp or shows shadows
- The maximum recommended VGA cable distance is 5 metres without ghosting and
degradation.
- Make sure you have used high quality video cables with coaxial cores. If the diameter of
the cable is less then 6mm then the cable may not be high enough quality.
2. The maximum recommended PS/2 cable distance is 5 metres. Normally, the cable length is
based on the electronic driver capacity of your motherboards PS/2 ports. If you need longer
PS/2 distances it may be necessary to use a PS/2 extender.
3. Don’t press any keys on the keyboard while the selected computer is booting up. Otherwise
it may cause a keyboard error, or the keyboard may not be detected at the PC side.
4. The computer boots up fine, but the keyboard doesn’t work
Make sure the keyboard works when directly plugged into the computer. Try a different
keyboard, but use standard PS/2 keyboards (some keyboards with extra multimedia keys
may not be supported).
5. The Mouse is not detected during PC boot up
- Make sure the mouse works when directly plugged into the computer. You have to install
the appropriate mouse driver on all connected computers!
- Make sure the mouse is a true PS/2 mouse. A combo mouse will work just as long as it is
set for PS/2 mode with the correct adapter. Try a different mouse.
- Some advanced mice like radio frequency mice, 5 button mice and scroll wheel mice use
very uncommon proprietary signals. Although LINDY has carefully checked for the highest
compatibility, we cannot guarantee that the P16-IP will work with all known mice, especially
those developed and produced after the P16-IP’s introduction.
- Avoid moving the mouse or pressing the mouse buttons when switching ports.
- Avoid switching ports during the PC shut down process.
6. If you have forgotten the OSD “password” please contact LINDY.
