NOTE      •  Be  sure  to  check  jack  type,  signal  level,  timing  and  resolution 
before connecting this projector to a computer.
•  Some  computers  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 
(
600x200),  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.
• The HDMI input does not support the signals marked with *.

RS-232C Communication (continued)
Requesting projector status (Get command)
( ) Send the request code Header + Command data (‘02H’+‘00H’+ type (2 bytes)+
‘00H’ +‘00H’) from the computer to the projector.
(2) The projector returns the response code ‘  DH’+ data (2 bytes) to the computer.
Changing the projector settings (Set command)
( ) Send the setting code Header + Command data (‘0  H’+‘00H’+ type (2 bytes) + 
setting code (2 bytes)) from the computer to the projector. 
(2) The projector changes the setting based on the above setting code.
(3) The projector returns the response code ‘06H’ to the computer.
Using the projector default settings (Reset Command)
( ) The computer sends the default setting code Header + Command data (‘06H’+
‘00H’ + type (2 bytes) +‘00H’+‘00H’) to the projector.
(2) The projector changes the specified setting to the default value.
(3) The projector returns the response code ‘06H’ to the computer.
Increasing the projector setting value (Increment command)
( )  The  computer  sends  the  increment  code    Header  +  Command  data  (‘04H’+
‘00H’+ type (2 bytes) +‘00H’+‘00H’) to the projecto\
r.
(2) The projector in creases the setting value on the above setting code.
(3) The projector returns the response code ‘06H’ to the computer.
Decreasing the projector setting value (Decrement command)
( )  The  computer  sends  the  decrement  code  Header  +  Command  data  (‘05H’+
‘00H’+ type (2 bytes) +‘00H’ + ‘00H’) to the projector.
(2) The projector decreases the setting value on the above setting code.
(3) The projector returns the response code ‘06H’ to the computer.
When the projector cannot understand the received command
When the projector cannot understand the received command, the error code ‘  5H’ 
is sent back to the computer.
Sometimes  the  projector  cannot  properly  receive  the  command.  In  such  a 
case,  the  command  is  not  executed  and  the  error  code  ‘ 5H’  is  sent  back  to  the 
computer. 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  ‘  CH’ 
+  ‘xxxxH’  is  sent  back  to  the  computer.  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 to the computer.
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.
