1. INTRODUCTION
The HDMI EDID Emulator is designed to allow the adjustment ofHDMI/DVI EDID information that is provided to a source device bya connected display so that it can output the correct video/audio
signal. Aiming to simplify the technical complications involved invideo/audio system integration, home theater installation, video/audio equipment testing and experimentation, the unit’s learning
function allows the user to Read and Write the video/audio EDID tothe system. It also supports EDID Emulation and Bypass modes.

6.3 EDID Learning Procedure
To Read the EDID:
1. Connect a TV/display to the HDMI output for EDID reading.
2.

Set the 'Emulator/Bypass (2)' switch to 'Emulator' first then set the'Rd/Wr (1)' switch to the 'Rd. (Read)' position.

3.

Press the 'Select' button for 3 seconds to put the unit into 'Learned'mode.

4.

Press the 'Select' button repeatedly to cycle through to therequired 1 to 8 EDID setting.

5.

Press the 'SET' button for 3 seconds to write the EDID to thecorresponding memory as indicated by the LED.

6.

When the 'STATUS' LED illuminates in Green the EDID learning has
been successfull but if the 'STATUS' LED is Red the learning has
failed.

To Write the EDID:
1. Connect a TV/display to the HDMI output for EDID writing.
2.

Set the 'Emulator/Bypass (2)' switch to 'Emulator' first then set the'Rd/Wr (1)' switch to the 'Wr. (Write)' position.

3.

Press the 'Select' button repeatedly to cycle through to therequired 'Learned/Default' 1 to 8 EDID setting.

4.

Press the 'SET' button for 3 seconds to overwrite the HDMI TV/
display EDID setting. The 'STATUS' LED will blink during the writing
process.

5.

When the 'STATUS' LED illuminates in Green the EDID writing has
been successful but if the Status LED is Red the writing has failed.
If the 'STATUS' LED did not blink and illuminate in Red it means TV's
EDID is not writable.

Warming: Once the writing is successfully done the original EDID
will be erased. It is recommended that the original EDID settings arebacked-up by storing them in the unit before performing the overwrite.
Caution is advised when using this function.
