Self-EDID Programming Procedure
The graphic source equipment generally requires display information (EDID). It contains
resolution and timing information of the display.
VGDF-200 supports Self-EDID programming. It is the procedure that reads the EDID from
the display and stores it in the EEPROM of the converter. We highly recommend do Self-
EDID once when you install your system with VGDF-200 for the first time.
Follow the steps
below to do it correctly.
Note1:
If you know that EDID is not required by the user
’s VGA source, Self-EDID
programming is not necessary.
Note2: The default EDID in factory ship-out is programmed in the VESA standard of
WUXGA (1920x1200), 60Hz.
Step 1
Connect 5V power adapter to turn VGDF-200.
Step 2
Power LED (Blue) will be turned ON.
Step 3
Push the EDID button on the rear side of converter with a narrow pin. Then, status
LED (Blue) will blink 3 times and turned ON.
Step 4
Connect the
VGA OUT
port on the front side of converter to
the VGA input port of
display
over VGA cable.
Then the status LED will begin to blink rapidly. It indicates
reading the EDID from the display and storing it in the EEPROM. After 8~10 sec
blinking, the status LED will be turned OFF and it indicates completion of all
procedure.
Step 5
Disconnect the converter from the display.
1-5 Self-EDID Programming Procedure
Troubleshooting
The display shows only black screen.
- Ensure that all plugs and jacks used by external power supplies (both
Opticis and others) are firmly connected. Ensure that the Power and status
LED ON.
- Ensure that the video ports are firmly plugged in to the PC and display.
- Ensure that the converter and receiver modules plugged correctly to the PC
and display, respectively.
- Check if the PC and display are powered on and properly booted.
- Re-boot up the system while connecting the optical DVI extension module.
Screen is distorted or displays noises.
- Check if the graphic resolution is properly set. Go to the display properties of
Windows and tap the settings.
- Ensure that the resolution sets less than WUXGA (1920x1200) at 60Hz
refresh ratio.
- Reset the system. Disconnect and reconnect the optical fiber or 5V power
adapters.
Maintenance
No special maintenance is required for the converter and power adapters.
Ensure that the converter and power adapters are stored or used in a benign
environment free from liquid or dirt contamination.
There are no user serviceable parts. Refer all service and repair issues to
Opticis.
