CONFIGURATION
EDID EXTERNAL IMPORTANT!
Move your 3-Channel DVI Extender transmitter unit to the video output devices and
connect the respective lower DVI IN port to the DVI cable on the output device.
When you switch on your 3-Channel DVI Extender (after connecting the power supply
cable), the EDID of the connected video output device is automatically read by the
3-Channel DVI Extender and saved in an EEPROM for each DVI IN port. The respective
LED will fl ash four times during the scanning process. You can then switch off your
3-Channel DVI Extender.
Once you have repeated this procedure individually or simultaneously for all three
channels, the original EDID of the output device will be available at each channel.
The EXTERNAL function described below has thus been automated. However, menu-
based import of the individual values is also possible via EXTERNAL 1 - 3:
Once the data has been read out successfully, you can reconnect your 3-Channel DVI
Extender TX to the video signal sources (see page 10).
As described on page 24, you will now fi nd the
original EDID of your video output device 1
under EDID / CHANNEL 1 / INTERNAL 1:
An NEC MultiSync LCD 2080UX+ was
recognized in the example shown here.
If you exchange your video output devices,
please remember to import the EDID of the
newly connected devices in the manner
described above.
