Obtaining EDID Data From Displays When Using the DXF-100 Interface
The DXF-100 is a transmitter/receiver combination that allows a digital flat panel display to
be located up to 1,000 meters (3,300 feet) away from the signal source. The transmitter and
receiver are interconnected by a single multimode optical fiber, and connect to the source
and display using DVI connectors.
The DXF-100 must be configured for its target display, before it is connected to the
multiviewer, otherwise the Extended display identification data (EDID) information listed in
XAdmin’s Status and Options page for the corresponding output card will not reflect the
actual values for the target display. XAdmin would not be reporting the actual timing data
from the display, but default values corresponding to the maximum resolution supported
by the DXF-100, i.e. 1920
× 1200. The DXF-100 interface is unidirectional from the
transmitter (multiviewer) to the receiver (display). For XAdmin to show timing data from the
display, the EDID information needs to be transmitted in the reverse direction: from the
display to the multiviewer.
To obtain a display’s timing information in XAdmin
• Connect the display directly to the DVI output of the multiviewer, by using a copper
cable. (This is not always practical, since the display can be far or mounted on a wall.)
• Alternatively, connect the DXF-100 transmitter to the DVI input connector on the
display, and then connect it to its power supply. The LED will flash for a few seconds
while the transmitter reads and stores the EDID information from the display. When the
LED stops flashing, disconnect the transmitter from the display and reconnect it to the
multiviewer. The EDID information from the display will now be visible in XAdmin. The
EDID information from the display will now be visible to the multiviewer. If the
multiviewer is configured to adapt itself to the native resolution of the display, the
resolution for the output will change automatically.
Notes
• Miranda offers a more versatile bidirectional interface, the DXF-200
DVI/HDMI Optical Extension System, which has superseded the DXF-100
interface. For more information on the DXF-200, contact your Miranda
sales representative.
