If the system fails to display a signal, power OFF all devices and check that the
following connections are properly installed:
• The fiber optic cable must be routed to the SC connectors on both the
Transmitter Unit and Receiver Unit. Check to ensure that the optical cable
is fully inserted into the connector port. Note that slight pressure on fiber
optic cable and/or connector should NOT have any influence on the image
quality of the signal.
• The supplied External AC Power Adapter should be connected to the
Receiver Unit.
• Check to ensure that the DVI source device is able to provide +5.0 VDC
with at least 180 ma of current on pin 14 of its DVI output connector. If
these conditions are not met, or are unknown, then an optional External
AC Power Adapter should be connected to the Transmitter Unit (part
number DVI-7208-PS).
Once all connections have been verified, power ON the monitor first, and then the
DVI signal source.
If the system still fails to display an image, check to ensure that the DVI signal
source is compatible with the display by making a direct connection between the
two so as to bypass the Single-Link DVI Fiber Optic Extender. If there is still no
image,then reprogram the EDID Memory as noted in Section 4.2 above. If there
is still no image then there is a compatibility issue between the source and the
display that must be resolved.
