Control sequence | Mitsubishi Electronics SL4SU, XL8U, XL5U specification

3)Control sequence

(1)Send the command from the personal computer to the projector.

(2)The projector will send a return command after it receives an end code. If the command is not received correctly, the projector will not send the return command.

(3)The personal computer checks the command and confirms if the sent command has been executed or not.

(4)This projector sends various codes other than the return code. When having a control sequence by RS- 232C, reject other codes from the personal computer.

•During signal switching, the command may not take effect even when the projector sends the return command. After signal switching completes, wait for the mode indication to disappear before sending the next command.

•When sending commands successively, wait to receive the return command of the current command before sending a next command.

•Keep intervals of at least 400 ms between receipt of a return command and sending of a next command.

[Example] When turning the power ON (Figures and symbols enclosed in quotation marks are ASCII codes.):

Sending commands		Status code from	Description
from the PC, etc.		the projector
30 30 21 0D			Command for POWER ON
'0' '0' '!' ' '

	30 30 21 0D		Command receipt confirmation
	'0'	'0' '!' ' '	(Command echo back)

• Any commands will not be executed for 10 seconds after the power is turned on.

4)Operation commands (Not executable in stand-by mode. When the commands for input select are sent while the splash screen is being displayed, the splash screen is only canceled.)

The operation commands are used for the basic operation setting of this projector. They may not be executed while the signals are changed. The operation commands have no data codes.

Operation	ASCII	HEX			Note
POWER ON	!	21h			This command is invalid for 1 minute after the power is turned off.
POWER OFF	"	22h			This command is invalid for 1 minute after the power is turned on.
INPUT COMPUTER	_r1	5Fh	72h	31h	This command will not be executed in Stand-by mode or the MUTE is executed.
INPUT VIDEO 1	_v1	5Fh	76h	31h	This command will not be executed in Stand-by mode or the MUTE is executed.
INPUT VIDEO 2	_v2	5Fh	76h	32h	This command will not be executed in Stand-by mode or the MUTE is executed.

[Example] When setting the input signal to COMPUTER (Figures and symbols enclosed in quotation marks are ASCII codes.):

Sending commands	Status code from	Description
from the PC, etc.	the projector
30 30 5F 72 31 0D		Command for setting the input
'0' '0' '_' 'r' '1' ' '		signal to COMPUTER 1

	30 30 5F 72 31 0D	Command receipt confirmation
	'0' '0' '_' 'r' '1' ' '	(Command echo back)

5)Volume commands (Not executable in stand-by mode. Possible only to read during muting.) The volume commands are used for the volume setting of this projector with the value.

ITEM	ASCII	HEX	VALUE
VOLUME	VL	56h 4Ch	00 - 31

How to set the grade

Use the ASCII codes to set the grade for setting data. Please refer to the table below for the HEX code.

ASCII	'0'	'1'	'2'	'3'	'4'	'5'	'6'	'7'	'8'	'9'
HEX	30h	31h	32h	33h	34h	35h	36h	37h	38h	39h

[Example] When setting the volume to 15 (standard value) (Figures and symbols enclosed in quotation marks are ASCII codes.):

Sending commands	Status code from	Description
from the PC, etc.	the projector
30 30 56 4C 31 35 0D		Command for setting the volume
'0' '0' 'V' 'L' '1' '5' ' '

	30 30 56 4C 31 35 0D	Command receipt confirmation
	'0' '0' 'V' 'L' '1' '5' ' '	(Command echo back)
