•The first byte of a command indicates the command type with 3 bits on the MSB side and the data length with 4 bits on the LSB side.

Projector - computer	Computer - projector
‘0xH’ : Error code	‘2xH’ : inquiry code
‘1xH’ : response code	‘3xH’ : setting code
‘70H’ : frame error code	‘4xH’ : default setting code

‘x’ indicates the data length (example: x=2 means a 2-byte command).

• The second byte of a command indicates the command contents.
