EDID (256 Bytes) contains EDID information of Output display 1.
3.2.11 Read Input EEPROM EDID

Read EDID stored on EEPROM of an Input.

Format of Command Line:

Start (*) + Router ID (3 byte) + Command (C) + Data Length (002) + Input
EEPROM (2 byte) + End (!)

Allows OHM-88 to respond with ACK signal to controller in the following format:
0x06(06h) + Connection DATA + 0x07(07h)
Example: Read EDID stored on EEPROM of Input 2

EDID (256 Bytes) contains EDID information stored on EEPROM 2.
3.2.12 EDID Write

Read EDID information from connected displays and writes EDID to each
EEPROM.

Format of Command Line:

Start (*) + Router ID (3 byte) + Command (D) + Data Length (Variable) +
EEPROM 1 (2 byte) + EEPROM 2 (2 byte) +
… +
End (!)

Variable in Data Length is determined by multiplying 2 bytes to the
maximum number of Input channels. With OHM-88, it is 16 bytes, multi-
plying 2 bytes by 8 inputs.
