Example of computer signal
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 illustrations in this manual are for illustrative purposes. They may differ slightly
from your projector.

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 (&11).
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 ful lls the speci cation
shown in 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 -
COMMUNICATION in the User's Manual - Operating Guide).

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 specied
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 undened
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.
