CHAPTER 8: Troubleshooting

The mouse is behaving erratically.

1.Reset the keyboard and mouse as described in Section 7.3.1.

2.Issue the Null Mouse Command up to three times (see Section 7.3.2).

3.If your PC is running Windows 95/98/2000, Windows Me, Windows NT, or Windows XP, regardless of what type of mouse you have, install the latest Microsoft driver for a standard mouse or (even if you have a standard mouse) the IntelliMouse. The Micro Extender will translate the mouse signals for this driver, and the driver will auto-correct the synching problem if you let go of the mouse for a second or two.

4.If you’re using the Micro Extender in conjunction with one of our ServSwitch family of KVM switches, command the Switch to reset the mouse.

5.Quit and restart the application.

6.Reboot the PC.

8.1.3BOTH KEYBOARD AND MOUSE

Neither the keyboard nor the mouse operates, or both have locked up.

1.If they have both locked up, first try resetting the keyboard and mouse as described in Section 7.3.1.

2.Reset the PC and try again.

3.If the problem is happening at the remote station, cycle power to the Remote Unit.

My Pentium class PC will not boot properly due to keyboard or mouse problems, or After my Pentium class PC boots, the keyboard and/or mouse won’t work.

Try “crossing” the keyboard- and mouse-extension cables running from the Extender’s Local Unit to your PC. That is, plug the keyboard cable or cable strand into the CPU’s mouse port and the mouse cable or cable strand into the CPU’s keyboard port.

If this works, here’s why: The BIOS installed in some machines with Intel Pentium family processors checks the PC’s keyboard and mouse ports at boot time. If it detects anything that leads it to suspect that the user has plugged the keyboard and mouse in backwards—that is, into each other’s CPU ports—it “remaps” the ports, so that the keyboard port functions as the mouse port and vice versa. BIOS of this type sometimes mistakenly activates port remapping when the PC is attached to an Extender.
