6. Appendix
Input Connector
Voltage applied across the pins of Ext_GPIN_P and
Ext_GPIN_N should be in the range from 3.3 Vdc to 10 Vdc.
Recommended Operating Current: 5mA
Absolute Maximum Rating:
• 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)

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.
