• Using GPIO Control
Momentary “ON” pulse enables you to control projector. To enable “ON” pulse, hold it for at least 500 ms. Hold “OFF” for at least
500 ms before “ON”. (See page 74)

Example for dousing image:
Input ON to 5-24 and 7-26 while 6-25 and 8-27 are OFF.
Example for selecting the preset button 2: Input ON to 5-24 and 8-27 while 6-25 and 7-26 are OFF.
NOTE
• The operation command coming from GPI/O port will be canceled when the projector is processing other tasks,
such as light source cooling and switching title.
• Set all other pins than those in use to “OFF”.
• The operation command is executed upon continuous input of the “ON” pulse for approximately 200 ms.
