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.
