There is a possibility that the interior portion has become heated. Turn the power OFF and wait
approximately 20 minutes. After the main unit has cooled down, please confirm whether or not
there is blockage of the air passage aperture, whether or not the filter is dirty, and/or whether or
not the peripheral temperature exceeds 35°C, etc. After performing any needed maintenance,
turn the power ON again; if the same display is displayed, then please change the lamp.

EXAMPLE OF COMPUTER SIGNAL
•Some computers may have multiple display screen modes. Use of some
of these modes will not be possible with this projector.
• Be sure to check jack type, signal level, timing and resolution before connecting this
projector to a computer.
• 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 (except DVI input) with resolution up to
UXGA (1,600 x 1,200), 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.
• The image may not be displayed correctly when the input sync. signal is “Composite
Sync.” or “Sync. on G”.
• UXGA (1,600 x 1,200) signals cannot be displayed with DVI input.NOTE

The following signals are used for the initial settings.
The signal timing of some computer models may be different. In such case, refer to
adjust the V.POSIT and H.POSIT of the menu.

							6Requesting 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 a command sent by the projector cannot be understood by the computer
When the command sent by the projector cannot be understood, the error command ‘15H’ is
returned by the computer. Some times, the projector ignores RS-232C commands during
other works. If the error command ‘15H’ is returned, please send the same command again.
When data sent by the projector cannot be practice
When the command sent by the projector cannot be practiced, the the error code ‘1cH’
+‘xxxxH’ is returned.
When the data length is greater than indicated by the data length code, the projector will
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 projector.
RS-232C COMMUNICATION (continued)
•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.
NOTE
