- It is a format to respond to certain commands. The difference from "Send to PDP" is the existence of "Check Sum".
- STX (0x02): The initiation Code. The beginning of Protocol. (Fixed value)
- Command: The code of actual execution (Dynamic value)
- Length: The length of "Data" area. (Dynamic value: "0"~"255")
- Data: "ID," "Ch1/Ch2" and other Data area (Dynamic value)
- ID: The code to distinguish DVI Converter. It is allocated in the rage of "101"~"109."
- Ch1/Ch2: The classification code for "Channel1" is "0x01", "Channel2" for "0x00." (Dynamic value)
- Check Sum: Add all the values of "STX~Data" and execute "Not" operation.
- ETX (0x03): The end of Protocol. (Fixed value)

- "Information" Communication Sequence
* Wait for the response for 40msec after sending commands. In case of response failure, it is recommended to
send the command again.
* It is recommended not to give the other command or change the resolution during transmission.
