both sides that light green when the unit is receiving power.
The LEDs on the transmitter also function as a status
indicator for the EDID minder feature (see “

A recessed switch activates the transmitter to capture
and store EDID information from the display device.
This allows the source device to provide a signal with a
resolution and refresh rate matching the needs of the
display device (see “
Setup and Operation ”).
Setup and Operation
When using the DVI 104 Tx/Rx for the first time or if the display device is changed, it is essential
to set up the EDID Minder. The setup process places EDID information on a EEPROM chip in
the transmitter, which allows the video source to boot up correctly. This process is described
below in
steps 1-6. If you have already set up the EDID Minder, proceed to step 7.
1. Ensure that the source, the display, 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 LEDs light a solid green.
3. Gently press and release the EDID Minder storage button, using a pointed device, such as a
paper clip. Both LEDs should blink twice and turn off, although power is still connected.
4. Power on the display device.
5. Connect the transmitter directly to the DVI input of the display device. The 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 LEDs stop blinking. They may light
steadily 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 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.
