Setup and Operation
By default, the transmitter/receiver pair are set to extend video
signals with a resolution of 1600 x 1200 @ 60 Hz. For display
devices that support this resolution and refresh rate, proceed to
step 7 . Otherwise, it is necessary for the transmitter to capture
and store the EDID of the display device, which is explained in
steps 1-6 .
1. Ensure that the source device, the display device, the
transmitter, and the receiver are all powered off and that
the fiber optic cables are unplugged from the transmitter
and the receiver.
2. Apply power to the transmitter by inserting the cable from
the external power supply into the input jack. The LED
should illuminate a solid blue.
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 blue
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 blue LED on the transmitter blinks
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 blue
LED lights steadily blue.
N 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 blue
LED is no longer blinking, disconnect the transmitter from
both the power and the display device.
N 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.
