When the G PO driver inside the p rojector becom es powerless the GPO sta te chang es to the defaul t 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): E nter or leave Sleep mode can be done with G P IO of
the Cinem a Controller via two predefine d Macros (not editable). Not with the G PIO of the ICMP.
The GPO s ignals of the ICM P will return to their default output level when the projector is switched to S leep mode. This c ould
generate unexpected "Falling Edge" triggers at the output pins. A lso when awakening the projector (from Sleep m ode to Standby
mode) the GP O signals of the ICMP 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 default output level w hen the projector is s witched to power-
off. This could generate unexpected "Falling Edge" triggers at the output pins. A lso during power-on the G P O signals may generate
unexpected "Rising Edge" ev ents.
