NOTE    • Be sure to check jack type, signal level, timing and resolution 
before connecting this projector to a computer.
• Some computers 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 i\
n 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.
• Automatically adjustment may not function correctly with some input sign\
als.
• The image may not be displayed correctly when the input sync signal is a\
  composite sync or a sync on G.

Connecting the cable
1. Turn off the projector and the computer.
2. 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.
3. Turn the computer on, and after the computer has started up turn the 
projector on.

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 specifi ed 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.
NOTE • Operation cannot be guaranteed when the projector receives an undefi 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.
