NOTE      •  Be  sure  to  check  jack  type,  signal  level,  timing  and  resolution 
before connecting this projector to a PC.
•  Some  PCs  may  have  multiple  display  screen  modes.  Use  of  some  of  these 
modes will not be possible with this projector.
• Depending on the input signal, full-size display may not be possible in some 
cases. Refer to the number of display pixels above.
•  Although  the  projector  can  display  signals  with  resolution  up  to  UXGA 
(  600x 200),  the  signal  will  be  converted  to  the  projector’s  panel  resolution 
before  being  displayed.  The  best  display  performance  will  be  achieved  if  the 
resolutions of the input signal and projector panel are identical.
• Automatic adjustment may not function correctly with some input signals.\
•  The  image  may  not  be  displayed  correctly  when  the  input  sync  signal  is  a 
composite sync or a sync on G.

RS-232C Communication
Connecting the cable
. Turn off the projector and the computer. 
2. Connect the CONTROL port of the projector with a RS-232C port of 
the computer by a RS-232C cable (cross). Use the cable that fulfills the 
specification shown in the previous page.
3. Turn the computer on, and after the computer has started up turn the 
projector on.

RS-232C Communication (continued)
Requesting projector status (Get command)
() Send the following request code from the PC to the projector.
	 Header	+	Command	data	(‘02H’	+	‘00H’	+	type	(2	bytes)	+	‘00H’ 	+	‘00H’)	
(2) The projector returns the response code  ‘1DH’	+	data	(2	bytes)
 to the PC.
Changing the projector settings (Set command)
() Send the following setting code from the PC to the projector.
		 Header	+	Command	data	(‘01H’ 	+	‘00H’	+	type	(2	bytes)	+	setting	code	(2	bytes))	
(2) The projector changes the setting based on the above setting code.
(3) The projector returns the response code 	‘06H’	
to the PC.
Using the projector default settings (Reset Command)
() The PC sends the following default setting code to the projector.
	 Header	+	Command	data	(‘06H’ 	+	‘00H’	+	type	(2	bytes)	+	‘00H’ 	+	‘00H’)	
(2) The projector changes the specified setting to the default value.
(3) The projector returns the response code 	‘06H’
 to the PC.
Increasing the projector setting value (Increment command)
() The PC sends the following increment code to the projector.
	 Header	+	Command	data	(‘04H’	+	‘00H’	+	type	(2	bytes)	+	‘00H’ 	+	‘00H’)	
(2) The projector increases the setting value on the above setting code.
(3) The projector returns the response code 
‘06H’ to the PC.
Decreasing the projector setting value (Decrement command)
() The PC sends the following decrement code to the projector.
	 Header	+	Command	data	(‘05H’ 	+	‘00H’	+	type	(2	bytes)	+	‘00H’ 	+	‘00H’)
(2) The projector decreases the setting value on the above setting code.
(3) The projector returns the response code ‘06H’ to the PC.
When the projector cannot understand the received command
When the projector cannot understand the received command, the error code  ‘15H’	
is sent back to the PC.
Sometimes  the  projector  cannot  properly  receive  the  command.  In  such  a  case, 
the  command  is  not  executed  and  the  error  code  ‘15H’	is  sent  back  to  the  PC.  If 
this error code is returned, send the same command again.
When the projector cannot execute the received command.
When the projector cannot execute the received command, the error code  ‘1CH’	+	
‘xxxxH’ is sent back to the PC. 
When  the  data  length  is  greater  than  indicated  by  the  data  length  code,  the 
projector ignore the excess data code. Conversely when the data length is shorter 
than indicated by the data length code, an error code will be returned t\
o the PC.
NOTE • Operation cannot be guaranteed when the projector receives an undefined command or data.• Provide an interval of at least 40ms between the response code and \
any other code.• The projector outputs test data when the power supply is switched ON, and when the lamp is lit. Ignore this data.• Commands are not accepted during warm-up.
