The receiver has an EEPROM (24LCS22A-SN: Micro Chip).
This EEPROM is used to store EDID data. The SCL signal can be switched by JP6/JP3 and the SDA
signal using JP7/JP4.
Note:
At factory default settings, the EEPROM stores temporary data to enable output of image data
from an image output device. The ID used in the data is a dummy ID for evaluation purposes.
So, do not use it for actual products.
