Mitsubishi Electronics UD8900U While using the LAN terminals, the LAN functions take precedence

•The projector may not receive a command when the splash screen is being displayed immediately after turning on the power. Use command “00r10” to cancel the splash screen.

•While using the LAN terminals, the LAN functions take precedence.

•For the LAN terminals, the same commands as those for connecting with the TCP/IP (port number 63007) are available. Note, however, that the response becomes slightly slower than when using the RS-232C terminals. For the use of LAN terminals, refer to “4. Execution procedure of RS-232C commands via LAN”.

•When the NAK isn’t returned, check the RS-232C command system (00COMMAND).

[Example 1] Turning ON the power. (Values enclosed in quotation marks are ASCII codes.):

• When ID is not specified:

Command sent from the PC	Status code returned	Description
	from the projector
‘30’ ‘30’ ‘21’ ‘0D’		Command for POWER ON
00!		(ID command is omitted.)
	‘30’ ‘30’ ‘21’ ‘0D’	Command receipt confirmation
	00!	(The statuses are echoed back as
		many as the number of the connected
		projectors.)

• When ID is specified (when the command is sent to the projector with the ID of “01” or “ALL”):

Command sent from the PC	Status code returned	Description
	from the projector
‘30’ ‘30’ ‘3B’ ‘30’ ‘31’ ‘3B’ ‘21’ ‘0D’		Command for POWER ON is sent to
00;01;!		the projector with the ID of “01” or
		“ALL.”
	‘30’ ‘ 30’ ‘3B’ ‘30’ ‘31’ ‘3B’ ‘21’ ‘0D’	The projector with the ID of “01”
	00;01;!	or “ALL” receives the command.
		(The status is echoed back from the
		projector with the ID of “01” or “ALL.”)

[Example 2] Selecting VIDEO as the input signal during auto positioning (Values enclosed in quotation marks are ASCII codes.):

• When ID is not specified:

Command sent from the PC	Status code returned	Description
	from the projector
30’ ‘30’ ‘5F’ ‘76’ ‘31’ ‘0D’		(During auto positioning)
00_v1		Command for selecting VIDEO as the
		input signal is sent out.
	‘30’ ‘30’ ‘5F’ ‘76’ ‘31’ ‘3A ’‘4E’ ‘0D’	The command is received by the
	00_v1:N	projector but cannot be executed.
		(NAK return)

• When ID is specified (when the command is sent to the projector with the ID of “01” or “ALL”):

Command sent from the PC	Status code returned	Description
	from the projector
‘30’ ‘30’ ‘3B’ ‘30’ ‘31’ ‘3B’ ‘5F’ ‘76’ ‘31’		(During auto positioning)
‘0D’		Command for selecting VIDEO as the
00;01;_v1		input signal is sent to the projector
		with the ID of “01” or “ALL.”
	‘30’ ‘30’ ‘3B’ ‘30’ ‘31’ ‘3B’ ‘5F’ ‘76’ ‘31’	The projector with the ID of “01” or
	‘3A’ ‘4E’ ‘0D’	“ALL” receives the command, but
	00;01;_v1:N	cannot execute it.
		(NAK return)
