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.

Example of PC signal

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 IMAGE menu.

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 command

table (&9).

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.

RS-232C Communication (continued)

NOTE • 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.

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.
