10) Reading command diagram

The projectors operating status, such as POWER-ON/OFF and the currently selected input terminal, etc. can be monitored.

POWER OFF	vP	0	76h	50h		30h

The PC sends the command without attaching the data code to it. On the other hand, the projector attaches to the received command its current operating status as the data code and send it back to the PC.

[Example] When checking the currently selected input terminal (when the INPUT VIDEO is being selected):

Sending commands	Status code from	Description
from the PC, etc.	the projector
30 30 76 49 0D		Command for checking the input terminal
'0' '0' 'v' 'I' '
	30 30 76 49 76 31 0D	Check result ( VIDEO)
	'0' '0' 'v' 'I'''v' '1' '

11)Menu setting commands (Not executable in stand-by mode. Possible only to read during muting.)

The menu setting commands are used for the menu setting of this projector. If the personal computer sends the command without attaching the data code, the projector attaches to the received command its current setting value as the data code and send it back to the PC.
