When the GPO driver inside the projector becomes powerless t he GPO state chang es to the d efault state.
The default GPO st ate depends o n the external system conn ected w ith the G PO port (pull-up or pull-down
circuitry).
GPIO and projector Sleep mode
In case the projector is equipped with a “S leep” mode (e.g. DP2K S series): E nter or leave Sleep mode can be done with GP IO of
the Cinema Controller via two predefined M acros (not editable). Not with the GPIO o f the ICMP.
The GP O 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 IC MP may generate unexp ected "Rising Ed
ge" ev ents.
GPO and projector switching On or Off
The GPO signals of the Cinema Controller and ICMP will return to their d efault output level when the projector is switched to power-
off. This could generate u nexpected "Falling E dge" triggers at the output pins . Also during power-on the GPO signals may generate
unexpected "Rising Edge" ev ents.
