Command Control via the Network
Automatic Connection Break
The TCP connection will be automatically disconnected after there is no 
communication for 30 seconds after being established.
Authentication
The projector does not accept commands without authentication success 
when authentication is enabled. The projector uses a challenge response type 
authentication with an MD5 (Message Digest 5) algorithm.
When the projector is using a LAN, a random 8 bytes will be returned if 
authentication is enabled. Bind this received 8 bytes and the Authentication 
Password and digest this data with the MD5 algorithm and add this in front of the 
commands to send.
Following is a sample if the Authentication Password is set to “password” and the 
random 8 bytes are “a572f60c”.
 ) Select the projector.
 2) Receive the random 8 bytes “a572f60c” from the projector.
 3)  Bind the random 8 bytes “a572f60c” and the Authentication Password 
“password” and it becomes “a572f60cpassword”.
 4)   Digest this bind “a572f60cpassword” with MD5 algorithm.
 
It will be “e3d97429adffa11bce1f7275813d4bde”.
 5)    Add this “e3d97429adffa11bce1f7275813d4bde” in front of the commands and 
send the data. 
Send “e3d97429adffa11bce1f7275813d4bde”+command.
 6)   When the sending data is correct, the command will be performed and the 
reply data will be returned. Otherwise, an authentication error will be \
returned.
• As for the transmission of the second or subsequent commands, the 
authentication data can be omitted when the same connection.

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 projecto
r.
• 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 
(1 600x1200), 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.
•  Automatically adjustment may not function correctly with some input signals.
• T he im age may not be dis played co rrectly when the  input sync s ignal is a 
composite sync or a sync on G.

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.
