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 (1600x1200), 
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
TM input does not support the signals marked with *.

RS-232C Communication
RS-232C Communication
When the projector connects to the computer by RS-232C communication, the 
projector can be controlled with RS-232C commands from the computer. 
For details of RS-232C commands, refer to RS-232C Communication / Network 
command table (
&17 ).
Connection
1. Turn off the projector and the computer.
2. Connect the projector's 
CONTROL port and the computer's RS-232C port 
with a RS-232C cable (cross). Use the cable that fulfi lls the specifi cation 
shown in fi gure 
3. Turn the computer on, and after the computer has started up turn the projector 
on.
4. Set the COMMUNICATION TYPE to OFF. (& OPTION menu - SERVICE -

3. Response code / Error code ("h" shows hexadecimal)
(1)   
ACK reply : 06h 
When the projector receives the Set, Increment, Decrement or Execute 
command correctly, the projector changes the setting data for the specified 
item by [Type], and it returns the code.
(2)   NAK reply : 15h 
When the projector cannot understand the received command, the projector 
returns the error code. 
In such a case, check the sending code and send the same command again.
(3)   Error reply : 1Ch + 0000h 
When the projector cannot execute the received command for any reasons, 
the projector returns the error code.   
In such a case, check the sending code and the setting status of the projector .
(4)   Data reply : 1Dh + xxxxh 
When the projector receives the GET command correctly, the projector returns 
the responce code and 2 bytes of data.
NOTE •  For connecting the projector to your devices, please read the 
manual for each devices, and connect them correctly with suitable cables. 
• 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.
•  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, the projector returns the error  code to the computer.
