6 .0 TROUBLESHOOTING
If the system fails to display a signal, power OFF all devices and verify that the
following connections are properly installed:
• Ensure the Transmitter Unit is connected to the source and the Receiver
Unit is connected to the Display using high quality HDMI cables.
• The fiber optic cable must be connected on both the Transmitter Unit
and Receiver Unit. Check to ensure that the optical cable is fully
inserted into the ports. Note that slight pressure on the fiber optic cable
and/or connector should NOT have any influence on the image quality of
the signal.
• The supplied External AC Power Adapters should be connected to both
the Transmitter and Receiver Units.
Once all connections have been verified, power ON the display first, and then
the HDMI signal source.
If there is no picture or if there are intermittent picture issues, please determine
whether the Fiber Link LEDs are lit. If the Fiber Link LEDs light up, then there may
be an EDID issue. Please check to be sure the appropriate EDID mode is being
used. See section 5.0 for information on setting the EDID mode of the extender.
If the Fiber Link LEDs are not lit, then it may be necessary to check the quality
and/or condition of the fiber optic cable being used. Fiber optic ports and cables
are very sensitive to dust, dirt and oil from handling. Even minute amounts of
obstructive material can interfere with or disrupt the optical transmission of the
video signals. If erratic performance or disruption is noted, it may be necessary
to have qualified technical personnel clean the optical ports and/or optical cable
using appropriate procedures and cleaning materials.

Note 6-1:
This product supports the use of both
Single Mode Fiber (SMF)
, and
Multi-
Mode Fiber (MMF)
. However, extra care is required when using SMF due to its smaller
optical aperture (8.9 microns) versus 50-60 microns for MMF. This smaller aperture means
that SMF optical cables have an increased risk of contamination due to dirt, dust, oils, etc.
that can be caused by poor handling.
If the system still fails to display an image, ensure that the HDMI signal source
is compatible with the display by making a direct connection between the two,
bypassing the Fiber Optic Extender. If there is still no image, then there is a
compatibility issue between the source and the display that must be resolved.
If the problem persists after trying the above suggestions, please contact your
dealer for additional assistance. If the dealer’s technical personnel are unable
to assist you, please contact DVIGear via telephone at 1.888.463.9927 (toll-free
