Installation Instructions
The Fiberlink® 7500 Series of ber optic transmission systems are ready for
immediate use and do not require any special tools or equipment. However, an Optical
Power Meter, such as the Fiberlink® 6615, can be useful in determining optical loss budgets
during your systems design and system maintenance.
The following instructions describe the typical installation procedure:
1) Power o your computer and the 7500 Series units.
2) Connect the DVI video source (Computer) to the video input DVI-D
connector on the transmitter unit.
3) Determine your EDID requirements and follow the procedures described in the
“Triple EDID Function” section of this manual.
4) Connect the video output(s) on the receiver unit to the DVI-D connector(s).
5) Connect the ber optic cable between the two Fiberlink units.
6) Connect the audio input signals to the transmitter stereo jack and the
audio output to the receiver stereo jack.
7) Apply power to both the Fiberlink units and the computer.
For box versions using DC power connections, refer to Figure 1.
8) When power is applied, the green POWER LED will light, indicating the presence
of operating power. The VIDEO LED will give an indication as described on page 13.
The green AUDIO LED will give an indication as stated on page 13.
9) The system should now be operational.
Note:
7500, 7501 and 7502 are not compatible with 7510, 7511, 7512, 7514, 7515, 7516
7510, 7511 and 7512 are not compatible with 7500, 7501, 7502, 7514, 7515, 7516
7514, 7515 and 7516 are not compatible with 7500, 7501, 7502, 7510, 7511, 7512
Note: The Rack Card version has an additional red LED for indicating the presence of an alarm
condition (loss of signal). Refer to Indicator LED’s and Alarm Switch Settings & Options sections
of this manual.
Installation Instructions
The transmitting element in the Fiberlink® 7500 transmitter
unit contains a solid state Laser Diode located in the optical
connector. This device emits invisible infrared electromag-
netic radiation which can be harmful to human eyes. The ra-
diation from this optical connector, if viewed at close range
with no ber optic cable connected to the optical connector,
may be sucient intensity to cause instantaneous dam-
age to the retina of the eye. Direct viewing of this radiation
should be avoided at all times!

Internal When the switch is in this position, the EDID will be
automatically generated. Alternatively, if EDID
information was previously captured and stored, the
unit will use the stored information.
Loop The EDID information will be passed through to the DVI
source from the display connected to the loop-through
port of the unit. If no loop-through display is connected,
the DVI source may not generate a DVI signal.
EDID Switch Settings
The EDID Switch has two positions, Internal and Loop, as described in the chart below. For
complete instructions on how to operate the 7500 Series’ Triple EDID function, please refer
to the “Triple EDID Function” section of this manual on page 8.

Fiberlink® 7500 Series
Triple EDID Function
The Fiberlink® 7500 Series of ber optic transmission systems come with a unique “Triple
EDID” feature set that allows you to capture and store EDID information, acquire EDID
information from a connected loop-through display, or allow the7500/7510 or 7502/7512
unit to generate the EDID internally, on-the-y. The procedure for implementing each are
described below.
Generating EDID internally when no EDID has been stored:
1) Power o your computer and the 7500 Series units.
2) Set the EDID switch to the “Internal” position.
3) Any DVI display can optionally be connected to the loop-through port
of the 7500/10/14 or 7502/12/16.
4) Power on your 7500/10/14 or 7502/12/16 Transmitter unit and the loop-through display.
5) Power on your computer.
6) The 7500/10/14 or 7502/12/16 is now operation and will generate EDID internally.
Using EDID from a loop-through display:
1) Power o your computer and the 7500 Series units.
2) Set the EDID switch to the “Loop” position.
3) Connect a display to the 7500/10/14 or 7502/12/16 loop-through port.
4) Power on your 7500/10/14 or 7502/12/16 Transmitter unit and the loop-through display.
5) Power on your computer.
6) The 7500/10/14 or 7502/12/16 is now operational and will use the EDID information
acquired from the loop-through display.
Capturing and storing EDID information:
1) Power o your computer and the 7500 Series units.
2) Set the EDID switch to the “Loop” position.
3) Connect a display to the 7500/10/14 or 7502/12/16 loop-through port.
4) Power on the loop-through display.
5) Power on your 7500/10/14 or 7502/12/16 Transmitter unit.
6) Press the ‘Capture EDID’ button on the Transmitter as shown in Figure 2.
The Video LED will ash, indicating the capture is in progress. Note that any previously
stored EDID information will be overwritten.
7) When the Video LED remains o, the capture is complete.
Note: This procedure will erase any previously stored EDID information.

Triple EDID Function (cont.)
Using stored EDID information:
Before you can use a stored EDID setting, you must capture and store EDID information as
described in the “Capturing and storing EDID information” procedure.
1) Power o your computer and the 7500 Series units.
2) Set the EDID switch to the “Internal” position.
3) Any DVI display can be connected to the loop-through port of the 7500/10/14 or
7502/12/16.
4) Power on your 7500/10/14 or 7502/12/16 Transmitter unit.
5) Power on your computer.
6) The 7500/10/14 or 7502/12/16 will now be using the stored EDID information.
Reseting back to factory defaults when EDID has been previously stored:
1) Power o your computer and the 7500 Series units.
2) Set the EDID switch to the “Internal” position.
3) Disconnect any display from the 7500/10/14 or 7502/12/16 loop-through port.
4) Power on your 7500/10/14 or 7502/12/16 Transmitter unit.
5) Press the ‘Capture EDID’ button to erase stored EDID information as shown in Figure 2.
6) The Audio LED should ash for conrmation.
7) Power on your computer.
8) The 7500/10/14 or 7502/12/16 is now operational and will generate EDID internally.
Operating Tips:
The 7500/10/14 or 7502/12/16 transmitter units can be temporarily power using a 9V
battery making it very easy to bring the transmitter to a ceiling mounted projector for EDID
capture and storage!
If you receive unexpected display results, you may be operating the 7500/10/14 or 7502/12/16
using EDID information that was stored during a previous installation. Try clearing any stored
EDID information.

Page 15Fiberlink® 7500 Series User’s Manual
Fiberlink® 7500 Series
Operating Pointers
The 7500 Series is available in versions that operate with multimode (MM, 62.5u, 50u) and
single mode (SM) optical bers. Be certain that the correct size ber is being used for this
particular transmitter/receiver combination.
Also, remember to check attenuation and bandwidth of the ber optic cable. The system
will only operate properly if these specications fall within the range of the system’s loss
budget.
Troubleshooting
Multimode ber optic cable contains an optical ber with a light carrying “core” that is
only .0025 inches (62.5 microns) in diameter. Single mode ber optic cable has an even
smaller “core,” only .00032 to .0004 inches (8-10 microns). This is smaller than a human hair!
Therefore, any minute particles of dirt or dust can easily block the ber from accepting or
radiating light. To prevent this from happening, always use the provided dust caps when
ever optical connectors are exposed to air. It is also a good idea to gently clean the tip of an
optical connector with a lint-free cloth moistened with alcohol whenever dust is suspected.
The status of the LEDs should provide the rst clue as to the origin of any operational
failure. If these are o, it usually means that the ber is broken or has too much attenuation.
Next, be certain that the input and output signal connections are correct.
An optical power meter, such as the Fiberlink® 6615, a visible light source, such as the
Fiberlink® 6610, and a Three Wavelength Light Source, such as the Fiberlink® 6620, can
greatly assist and expedite troubleshooting of ber optic transmission systems and are
recommended tools all installers should have available.
Finally, although multimode and single mode devices may look the same, they will not
operate properly together. Using the wrong device or ber can easily add more attenuation
than specied, resulting in poor overall performance.
If, after reviewing the above possibilities, the system is still not operating, please contact
the Customer Service Department for further assistance. If you suspect your problem is
caused by the optics or the ber optic cable, and you have an optical power meter, please
take the appropriate measurements prior to contacting support.
