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.

Initial set signals

The following signals are used for the initial settings. The signal timing of some

PC models may be different. In such case, adjust the items V POSITION and H

POSITION in the IMAGE menu.

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.

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 -

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 specied

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 undened

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.
