Commands consist of 2 command bytes and following data bytes.
The first byte indicates the kinds of commands and the length of the command.
‘0xH’ : Error-reply Projector sends to computer.
‘1xH’ : Command reply Projector sends to computer.
‘2xH’ : Ask command Computer sends to Projector.
‘3xH’ : Set command Computer sends to Projector.
‘4xH’ : Default set command Computer sends to Projector.
‘5xH’ — ‘FxH’ : Reserved
‘x’ indicates the length of data bytes.
The second byte indicates the command code ‘yy’ as listed in the command table.
The control data table shows the data byte.
