CHAPTER 7: Troubleshooting
7.3 Other Problems and Possible Solutions
Problem:
Poor video quality with smearing, fuzziness, or rippling.
Possible Solution:
Make sure that the video compensation has been set for your system, as described in Sections 4.2.1 and 4.2.2.A. Check for video skew; see Section 7.2. Make sure your Category 5 cable is pinned and paired properly; see the Appendix. Also, if you are using cables other than those that came with the Extender to make your video connections, make sure these are shielded or screened coaxial video cables.
Problem:
Your mouse does not move the cursor/pointer.
Possible Solutions:
1.Watch the receiver’s LED while you move the mouse. If you move the mouse and the LED doesn’t flash, then the Extender is not receiving data from the
2.Check the mouse’s connection to the receiver and the CAT5 cabling between the receiver and transmitter; if the cable connections are OK, try removing and restoring power to the Extender.
3.If you are attempting to connect the mouse to a PS/2 mouse port on a CPU that has not been powered down, you will need to use the
4.Make sure that you have an appropriate mouse driver loaded and that your computer’s software is configured to accept a supported mouse of the type that you have connected. See the relevant paragraphs in Section 3.1.
5.Make sure that (a) the mouse and computer were both connected to the Extender before any part of the system was powered up, and (b) the Extender was powered ON before the attached computer. If you’re not sure whether this was the case, then (if it’s possible to do so) power everything down, make sure all cable connections are correct and secure, power up the Extender’s receiver, then power up all attached computers.
Problem:
Your keyboard does not function or functions only intermittently. The Num Lock LED does not always light when the Num Lock key is pressed.
Possible Solution:
Some older keyboards were designed for use with specific computers and are not truly PC/AT or PS/2 compatible. These are not common, but if you’re having problems like this and you’re using an old keyboard, try a newer keyboard.
