7. Troubleshooting
If you experience problems when installing or using the Extender C5 modules please check through this section
for a possible solution.
Video image at the REMOTE module is distorted or shadows appear to the right of displayed objects.
Video compensation is required to compensate for the length of the twisted pair cable being used. If video
problems persist:
•
Please refer to
section 5.7 ‘Video compensation.’
•
If the overall video image is ‘fuzzy’ and/or has coloured shadows you may need to use the optional C5
Series Skew Compensator. This stand-alone passive module allows you to finely tune the red, green
and blue video signal timings (each of which is fed along separate twisted pairs) to overcome most
colour separation problems. Please refer to
section 5.8 ‘Skew Compensator.’
No video image is received at the REMOTE module
•
Check that the power/activity indicators are lit on the LOCAL and REMOTE modules - if they are not,
then there is a power problem. When keys are pressed or the mouse is moved, check that the indicators
flicker – if they do not then there could be a twisted pair link problem or a problem with one of the
modules.
•
Check that the Category 5 (or higher) cable is wired correctly as per the diagram in the
section 5.8
‘Skew Compensator’.
•
If possible, try using an alternative twisted pair connection between the modules.
•
If the REMOTE module is severely over compensated, the monitor may not be able to display a picture.
Try manually reducing the video compensation. Please refer
to section 5.7 ‘Video compensation.’
•
Temporarily disconnect the video link to the LOCAL module, connect a monitor directly to the computer
video port and check for a correct video image output.
Power is applied via the power supply but REMOTE module operation has stopped.
•
Each module has an internal automatic cut-out fuse to protect against power surges. To reset, remove
power from the module for one second and then reconnect.
The on-screen mouse pointer does not respond to mouse movements
•
The mouse connection may have been interrupted. Either, reboot the system and re-power the
REMOTE module power supply, or try using the mouse restoration command. Please refer to
section
5.6 ‘Hot plugging and mouse restoration.’
