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.

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.
