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.
• This projector will display up to UXGA (1600X1200) resolution signals but the image
will be rescaled to the native resolution of the projector. Best display performance is
achieved when the signal input resolution is the same as the native resolution of the
projector.
• The image may not be displayed correctly when the input sync. signal is “Composite
Sync.” or “Sync. on G”.

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.

Intended Use
Before operating this machine, please read this entire manual thoroughly. The 3MTM Multimedia Projectors are designed, built, and tested for use indoors,
using 3M lamps, 3M ceiling mount hardware, and nominal local voltages.
The use of other replacement lamps, outdoor operation, or different voltages has not been tested and could damage the projector peripheral equipment
and/or create a potentially unsafe operating condition.
3M Multimedia projectors and Wall Display Systems are designed to operate in a normal office environment.
• 16˚ to 29˚C (60˚ to 85˚ F)
• 10- 80 %RH (without condensation)
• 0- 1828 m (0-6000 feet) above sea level
The ambient operating environment should be free of airborne smoke, grease, oil and other contaminates that can affect the operation or performance of the
projector.
Use of this product in adverse conditions will void the product warranty.
