When the GPO driver inside the projector becom es pow erless the GP O state changes to the default state.
The default GPO state depends on the external system connected with the G PO port (pull-up or pull-down
circuitry).
GPIO and projector Sleep mode
In case the projector is equipped with a “Sleep” m ode (e.g. DP2K S series): Enter or leav e Sleep mode can be done with GPIO of
the Cinem a C ontroller v ia two predefined M acros (not editable). Not with the GPIO o f the ICMP.
The GPO signals of the ICMP will return to their default output level when the projector is switched to Sleep mode. This could
generate unexpected "Falling Edge" triggers at t he output pins. A lso when awakening the projector (from Sleep m ode to Standby
mode) the GPO signals of the IC MP may generate unexpected "Rising Ed
ge" events.
GPO and projector switching On or Off
The GPO signals of the Cinema Controller and ICMP will return to their default output level when the projector is s witched to power -
off. T his could generate u nexpected "Falling E dge" triggers at t he output pins. A lso during power-on the GPO signals may generate
unexpected "Rising Edge" events.
