DVI 104 Tx/Rx, cont’d
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.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.
NThe 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.
NOnce 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
