When the GPO driver inside the projector becomes powerless the GPO state changes to the default state.
The default GPO state depends on the external system connected with the GPO port (pull-up or pull-down
circuitry).
GPIO and projector Sleep mode
In case the projector is equipped with a “Sleep” mode (e.g. DP2K S series): Enter or leave Sleep mode can be done with GPIO of
the Cinema Controller via two prede
fi ned Macros (not editable). Not with the GPIO of 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 the output pins. Also when awakening the projector (from Sleep mode to Standby
mode) the GPO signals of the ICMP may generate unexpected "Rising Edge" 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 switched to power-
off. This could generate unexpected "Falling Edge" triggers at the output pins. Also during power-on the GPO signals may generate
unexpected "Rising Edge" events.
