3. Press and release the EDID Minder programming button by gently inserting a pointed device, such as a paper clip, into the recess
on the side of the transmitter. The green LED should blink twice and turn off, although power is still connected. The transmitter is
ready to capture EDID information from the display device.
4. Power on the display device.
5. Connect the transmitter directly to the DVI input of the display device. The green LEDs on the transmitter blink rapidly for a few
seconds to indicate that it is reading and storing EDID information from the display device.
When the information has been captured and stored, the green LEDs stop blinking. They may light a solid green or they may turn
off, depending on the display device.
NOTE: The transmitter must remain connected to both the display device and the power supply for the entire time that the
EDID capture is taking place.
6. Once the capture and storage are complete and the green LEDs are no longer blinking, disconnect the transmitter from both the
power and the display device.
NOTES:
• Once the transmitter has captured the EDID information from the display device, the information is stored on an EEPROM
chip in the transmitter. Therefore, this calibration needs to be performed only once, as long as the display device is not
changed.
• If the display device is changed, repeat steps 1-6 to capture and store the EDID information for the new device.
7. Apply power to the receiver by inserting the cable from the external power supply into the input jack. The LEDs should illuminate a
solid green.
8. Ensure that the display device is still powered on, connect the receiver directly to the DVI input, and tighten the thumbscrews.
9. Ensure that the PC or source is powered off, connect the transmitter directly to the DVI input, and tighten the thumbscrews.
10. If required, apply power to the transmitter by inserting the cable from the external power supply into the input jack. The LEDs
should illuminate a steady green.
NOTE: If the PC or source is able to provide 5 VDC on pin 14 of its DVI output, the transmitter can draw power from the
source device. If the source is a laptop or a PC using a PCI-E graphics card, the source device cannot provide enough
power and the transmitter must be powered with a separate external power supply.
11. Connect all four fiber optic cables between the transmitter and receiver. Pay attention to the orientation of the LC connectors and
ensure that each cable joins ports with the same number (port 1 of the transmitter must be connected to port 1 of the receiver,
and so forth).

12. Turn on the source device. The source device should read the information stored in the transmitter and boot up to that resolution
and refresh rate.
