9) Reading command diagram

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

	ASCII				HEX

The PC sends the command without attaching the data code to it. On the other hand, the projector attaches to the received command it’s 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 1 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 1)
	'0' '0' 'v' 'I' 'v' '1' ' '

10)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 it’s current setting value as the data code and send it back to the PC.

*1) When sRGB is ON, only the main data are effective. *2) Setting range differs depending on the input signals.

•Some commands are not executed depending on the input signal. The operational restrictions same as those on the menu setting are applied. Refer to “Menu operation” in the User Manual for more details.
