Self-EDID Programming Procedure
The graphic source equipment generally requires communication of display information
(EDID). Display information (EDID) contains resolution and timing information for your
display.
M1-203D-TR supports Self-EDID programming. Self-EDID programming means that
the EDID from the display is stored in the transmitter. You should use Self-EDID
programming feature if the resolution of the display is not UXGA(1600x1200). Follow
these steps to record the EDID of the display into the transmitter unit.
Note1
:
If you know that EDID is not required by the source, Self-EDID
programming is not necessary.
Note2 : The default EDID in factory ship-out is programmed in the VESA standard
of UXGA (1600x1200) 60Hz.
Step 1
Power on the display.
Step 2
Plug the 12V DC power adapter into the transmitter.
Step 3
Push and stay the ‘Self-EDID’ button of the transmitter with a pin until EDID
PRGN. LED is blinking once.
After blinking of Self-EDID LED 4
th
times, LED
will be automatically turned off.

Step 4
Connect the transmitter to the display while turned on, not to the PC.
The
LED on the transmitter will begin to blink rapidly. Blinking indicates reading the
EDID. LED will be turned OFF after blinking about 19 sec. The monitor EDID
has been recorded.
Step 5
Disconnect the transmitter from the display. Then, LEDs are lit again.
1-5 Self-EDID Programming Procedure
Troubleshooting
The display displays only black screen.
- Ensure that all plugs and jacks used by external power supplies (both
Opticis and others) are firmly connected. Ensure the red for Power and
green for Optic
LED ON.
- Ensure that the DVI ports are firmly plugged in to the PC and display.
- Ensure that the transmitter and receiver modules plugged correctly to the
PC and display, respectively.
- Check if the PC and display are powered on and properly booted.
- Reset the system by de-plugging and re-plugging the transmitter DVI port or
receiver DVI port, or by de-plugging and re-plugging the power cord plugs of
transmitter and receiver modules.
- 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 DVI cables or 12V
power adapters.
Maintenance
No special maintenance is required for the optical DVI module and power
adapters. Ensure that the DVI modules 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.
