• 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 53)
Here is function list to control projector by using GPIO port.

Example for dousing image: 4-23 is pulsed with keeping 3-22 off.
Example for selecting Macro 2: 3-22 and 4-23 are pulsed simultaneously with keeping 6-25 and 5-24 off.
NOTE • The operation command coming from GPI/O port will be canceled when the projector is processing other
tasks, such as lamp 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.
