Command data
Caution
If computer sends the undefined command code or data code, Projector can not guarantee operation.
Command is consisted of 2 command bytes and following data bytes.
1-st byte indicates the kinds of commands and the length of 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.
2-nd byte indicates the command code 'yy' as command table.
Data table shows the data byte.
