Appendix A. Troubleshooting
A.1 No video image is displayed on the remote monitor
• Checktheyellowindicatorsonthelocalandremotemoduleswhilenokeysarepressedonthekeyboardandnomousemove-
ments are being made - both indicators should be continually on when a valid video signal is present.
LOCAL: If the yellow indicator is giving a regular flash (twice per second), then the video feed to the local module is not valid.
Try connecting a DVI monitor (preferably using the same DVI link cable as used with the local module) directly to the computer
and check for a correct image.
REMOTE: If the yellow indicator is giving a regular flash (twice per second), then the video feed via the link cable is not valid. If
the link cable is long, try using a short link cable temporarily to check for basic operation.
If the yellow indicators are off, then the link cable is not properly connected.
