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 (
19).
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.
