6)Remote commands (Not executable in stand-by mode. When the remote commands are sent while the splash screen is being displayed, the splash screen is only canceled.)

Some remote control operations can be achieved by the remote command codes. The remote commands have no data codes.

[Example] When displaying the MENU selection bar (Figures and symbols enclosed in quotation marks are ASCII codes.):

Sending commands	Status code from	Description
from the PC, etc.	the projector
30 30 72 35 34 0D		Command operating the same
'0' '0' 'r' '5' '4' ' '		as the MENU button
	30 30 72 35 34 0D	Command receipt confirmation
	'0' '0' 'r' '5' '4' ' '	(Command echo back)

7) Password lock commands

The password lock commands control the password lock. The password lock enabling or disabling command is sent with a 4-digit figure (password) added to the end of the data code. When the password lock is enabled or disabled successfully, the projector sends a return command comprising the data code, password, and “1” at the end. When enabling or disabling the password lock fails, it sends a return command with “0” at the end. There is no reconfirmation of the password.

ITEM	ASCII	HEX		VALUE
Password lock	PSLOCK	50h 53h 4Ch 4Fh	43h 4Bh	0****(Disabling), 1****(DISPLAY INPUT)
enabling/ disabling				2****(MENU ACCESS)

****is a 4-digit figure (password).

8)Reading command diagram

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

	ASCII				HEX
	Function	Data (Receive)		Function		Data (Receive)
POWER ON	vP	1	76h	50h		31h
POWER OFF	vP	0	76h	50h		30h
INPUT COMPUTER	vI	r1	76h	49h		72h	31h
INPUT COMPONENT	vI	c1	76h	49h		63h	31h
INPUT HDMI	vI	d1	76h	49h		64h	31h
INPUT VIDEO	vI	v1	76h	49h		76h	31h
INPUT S-VIDEO	vI	v2	76h	49h		76h	32h
POWER ON/OFF INPOSSIBLE	vPK	0	76h	50h	4Bh	30h
POWER ON/OFF POSSIBLE	vPK	1	76h	50h	4Bh	31h
NO SIGNAL SUPPLIED	vSM	0	76h	53h	4Dh	30h
SIGNAL SUPPLIED	vSM	1	76h	53h	4Dh	31h

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 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' ' '
