CHAPTER 8: Troubleshooting
Connecting a keyboard to the Remote Unit has an adverse effect on the remote video.
Try using a newer keyboard. (Some older keyboards require too high a current for
the Remote Unit to properly drive the video signal.)
When I don’t use a keyboard, the Extender doesn’t work at all.
See
Section 8.1.7
.
8.1.2 M
OUSE
There is a mouse cursor on the screen, but the mouse does not work.
1. Reset the mouse as described in
Section 7.3.1
.
2. Check the mouse cable and (if necessary) the mouse portion of the extension
cabling to your CPU or KVM switch; if it’s loose, or if you have the keyboard
and mouse cabling reversed (plugged into each other’s Extender-port
connectors), plug the cabling in properly and reset the mouse as described in
Section 7.3.1
.
3. If your PC is a Pentium class machine, see the entry for the “My Pentium class
PC...” problem in
Section 8.1.3
.
4. Check the interconnect cable between the Extender’s Local and Remote
Units. Is it intact along its length and securely connected at both ends? And is
it wired correctly? (Compare its wiring with that shown in
Appendix A
.)
5. Try powering the Remote Unit OFF and then ON again.
6. Try using a different model of mouse.
The system does not detect a PS/2 mouse, or the application cannot find the mouse.
1. Check the mouse cable and (if necessary) the mouse portion of the extension
cabling to your CPU or KVM switch; if it’s loose, or if you have the keyboard
and mouse cabling reversed (plugged into each other’s Extender-port
connectors), plug the cabling in properly and reset the mouse as described in
Section 7.3.1
.
2. Make sure that the cable running from the keyboard port of the CPU or KVM
switch to the Extender’s Local Unit is intact and securely attached, so that it
provides power to the Local Unit.
3. If your PC is a Pentium class machine, see the entry for the “My Pentium class
PC...” problem in
Section 8.1.3
.
4. Reboot the PC.
