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...

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.

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.
