Caution
✓
Note - Used to emphasize important conditions or details.
2. Close supervision is necessary when any appliance is used by or near children. Do not leave appliance unattended while in use.
3. Never look directly into the projector lens when the lamp is on. The mercury lamp produces a strong light that could damage your eyesight.
4. Care must be taken, as burns can occur from touching hot parts.
Caution
6. Position the cord so that it will not be tripped over, pulled or placed in contact with hot surfaces.
7. If an extension cord is necessary, a cord with a current rating at least equal to that of the appliance should be used. Cords rated for less amperage than the appliance may overheat.
8. Always unplug appliance from electrical outlet before cleaning and servicing and when not in use. Grasp plug and pull to disconnect.
5. Do not operate appliance with a damaged cord or if the appliance has been

3M™ Multimedia Projector MP7740
33
Appendix
Requesting projector status (Get command)
1. Send the request code Header + Command data (‘02H’ + ‘00H’ + ‘xxH’ + ‘yyH’ + ‘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’ + ‘xxH’ + ‘yyH’ + data) 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’ + ‘xxH’ + ‘yyH’ + ‘00H’) to the projector.
2. The projector changes the specified setting based 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 command code (‘04H’ + ‘00H’ + ‘xxH’ + ‘yyH’ + ‘00H’ + ‘00H’) to the projector.
2. The projector increases 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 command code (‘05H’ + ‘00H’ + ‘xxH’ + ‘yyH’ + ‘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. Sometimes 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 practiced
When the command sent by the projector cannot be practiced, 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.
• Operation cannot be guaranteed when the projector receives an undefined command or data.
Caution
• Provide an interval of at least 40 ms 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.
