Troubleshooting
If you experience problems when installing or using the AdderLink AV modules,
please check through this section for a possible solution. If your problem is not
listed here and you cannot resolve the issue, then please refer to the ‘Getting
assistance’ section.
No video image is received at the receiver module.
• Check that the both the red power indicators are lit on both the transmitter
and receiver modules - if they are not, then there is a power problem. Both
modules require power from their supplied power adapters.
• Check that the green video input indicators are lit on both the transmitter
and receiver modules - if one or both are not lit, then a valid video input
signal is not present at the input to that module.
• Check the link cable(s) that connect the transmitter and receiver module(s)
for soundness and correct wiring as per the diagram in the ‘Skew
compensation adjustments’ section in the ‘Operation’ chapter.
• If possible, try using an alternative twisted pair link connection between the
modules.
• If the sharpness control is set too high, the monitor may not be able to
display a picture. Try reducing the sharpness setting. Please refer to the
‘Adjustments’ section in the ‘Special Configuration’ chapter.
• If not already fitted, connect a monitor to the
OUT
port of the transmitter
module and check for a correct video image output.
Video image at the receiver module is distorted or shadows appear to
the right of displayed objects.
Adjustments are required to compensate for the length of the twisted pair cable
being used. If video problems persist:
• Please refer to the ‘Brightness and sharpness adjustments’ section in the
‘Operation’ chapter.
• If the overall video image is ‘fuzzy’ and/or has coloured shadows you may
need to make skew adjustments (AdderLink AV101 receivers only). This
procedure allows you to finely tune the red, green and blue video signal
timings to overcome most colour separation problems. Please refer to the
‘Skew compensation adjustment’ section in the ‘Operation’ chapter.
Power is applied via the power supply but the 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.
No sound can be heard on the speakers connected to the receiver
module
• If not already fitted, connect speakers to the
OUT
port of the transmitter
module and check for a correct audio output.
• Check that the both the red power indicators are lit on both the transmitter
and receiver modules - if they are not, then there is a power problem. Both
modules require power from their supplied power adapters.
