TROUBLESHOOTING
31 4.4 Keyboard & Mouse When I am typing, I get wrong or missing characters on the screen.
Your keyboard may be in the wrong mode. Use the appropriate commands to reset
the keyboard and mouse as described in the manual supplied with your Remote
Unit.
The PC comes up with ‘keyboard error’.
Press <F1> or <ESC>. If the keyboard now operates correctly, you need to adjust
the BIOS setup to disable keyboard testing during booting.
The system does not detect a PS/2 mouse.
If connecting a Local Hub port to a live system, connect the mouse cable to the
CPU before keyboard connection to ensure the mouse is enabled correctly. Try
issuing the Mouse Recovery command.
Check that the mouse cable is connected properly and securely. Reboot the system.
The mouse pointer moves erratically.
Reset the keyboard and mouse as described in the previous sections.
Issue the Mouse Recovery command up to three times.
Ensure that you have the latest driver for your mouse.
If you are using the Hub port with a KVM switch, command the switch to reset the
mouse.
Quit and restart the application.
Reboot the PC.
When I ‘hot-plug’ the Local Hub port, the mouse no longer moves.
When connecting a Hub port to a live system, connect the mouse cable to the CPU
before keyboard connection to ensure the mouse is enabled. Try issuing the Mouse
Recovery command.
Some of the mouse buttons don’t work.
The Extenders support standard 2/3-button mice (with or without a wheel).
Additional buttons will not operate.
I have an enhanced keyboard with extra keys and indicators. Everything works apart from
these additional features.
The extender emulates a generic PS/2 keyboard. To support other keyboards (or
cascaded KVM switches), special firmware offering a transparent mode may be
required. Please contact Technical Support to discuss your application.
