•Be sure to check jack type, signal level, timing and resolution before

connecting this projector to a computer.

•Some computers may hove 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 (1600 x 1200),

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.

•Automatically 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.

memo About the details of RS-232C communication, please refer to the

following page.

RS-232C Communication

Connecting The Cable

Turn off the projector and the computer power supplies.

Connect the CONTROL port of the projector with a RS-232C port of the computer by

a RS-232C cable. Use the cable that fulfills the specification shown in the previous

page.

Turn on the computer power supply and after the computer has started up, turn on

the projector power supply.

4INCREMENT Increment setup value by 1.

5DECREMENT Decrement setup value by 1.

6EXECUTE Run a command.

RS-232C Communication (continued)

Requesting projector status (Get command)

(1) Send the request code Header + Command data (‘02H’+‘00H’+ type (2

bytes)+‘00H’+‘00H’) from the computer to the projector.

(2) The projector returns the response code ‘1DH’+ data (2 bytes) to the computer.

Changing the projector settings (Set command)

(1) Send the setting code Header + Command data (‘01H’+‘00H’+ type (2 bytes) +

setting code (2 bytes)) from the computer to the projector.

(2) The projector changes the setting based on the above setting code.

(3) The projector returns the response code ‘06H’ to the computer.

Using the projector default settings (Reset Command)

(1) The computer sends the default setting code Header + Command data (‘06H’+‘00H’+

type (2 bytes) +‘00H’+‘00H’) to the projector.

(2) The projector changes the specified setting to the default value.

(3) The projector returns the response code ‘06H’ to the computer.

Increasing the projector setting value (Increment command)

(1) The computer sends the increment code Header + Command data (‘04H’+‘00H’+

type (2 bytes) +‘00H’+‘00H’) to the projector.

(2) The projector in creases the setting value on the above setting code.

(3) The projector returns the response code ‘06H’ to the computer.

Decreasing the projector setting value (Decrement command)

(1) The computer sends the decrement code Header + Command data (‘05H’+‘00H’+

type (2 bytes) +‘00H’ + ‘00H’) to the projector.

(2) The projector decreases the setting value on the above setting code.

(3) The projector returns the response code ‘06H’ to the computer.

When the projector cannot understand the received command

When the projector cannot understand the received command, the error code ‘15H’ is

sent back to the computer.

Sometimes the projector cannot properly receive the command. In such a case, the

command is not executed and the error code ‘15H’ is sent back to the computer. If this

error code is returned, send the same command again.

When the projector cannot execute the received command.

When the projector cannot execute the received command, the error code ‘1cH’ +

‘xxxxH’ is sent back to the computer. 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, an

error code will be returned to the computer.

•Operation cannot be guaranteed when the projector receives an

undefined 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.
