Using the EDID Minder to read and store EDID
from a display
During boot up, the DVI-D source device uses Display Data
Channel (DDC) to obtain Extended Display Identification Data
(EDID) from the display device. This allows the output signal to
match the resolution and refresh rate of the display device.
The DVI DL 201 Tx/Rx uses Extron's EDID Minder, which
allows the user to store and use EDID from any display device.
To use this feature, follow these steps:
1
.
Disconnect all devices and cables from the transmitter and
receiver.
2
.
Connect the desired display to the transmitter's Local
Monitor output. For best results, the cable for this
connection should be 15' (4.5 m) or shorter.
3
.
Apply power to the transmitter and the display device. If
necessary, connect the power supply to the transmitter.
4
.
Set the EDID Minder switch on the transmitter
to the on (up) position (see the figure at right).
5
.
Set the Default EDID switch to the off (down)
position (see the figure at right).
6
.
Set the Remote DDC to the off (down)
position to allow DDC routing to go to the
local monitor (see the figure at right).
N
The EDID Minder extracts information only from the
local monitor, not from the remote display.
7
.
Press and release the EDID Minder Store
button. The LED next to the switch turns
from green to amber. This indicates that
the transmitter is reading and extracting
the EDID from the display connected to
the local monitor output.
When the information has been successfully extracted and
stored in non-volatile memory, the LED returns to green.
8
.
Turn off the display and disconnect it from the transmitter.
9
.
Connect the transmitter to the receiver with the three
twisted pair cables.
