procedure:
If the CPU of the LCD projector has received the data correctly, it returns an ACK(C5H). If the received data is not correct, the CPU returns a
NAK(CAH), then the following status:
Receiving success: C5
Receiving failure: CA Err
Err 01: Command Error (command not supported)
Err 02: Checksum Error
Err 03: Busy (command not acceptable)
NOTE:  If failing in powering-on, the CPU returns the following NAKs:
CA Err 1
