•
Generate Falling Edge
– generate a falling edge on the external GPO port if the present state of the output is high. If the
present state of the external GPO is low, no edge will be generated.
•
Generate Rising Edge
– generate a rising edge on the external GPO port if the present state of the output is low. If the present
state of the external GPO is high, no edge will be generated.
•
Generate Toggle
– generate a toggle on the external GPO port. If the present state of the output is low, a rising edge will be
generated, followed by a falling edge. If the present state of the output is high, a falling edge will be generated, followed by a
rising edge. Pulse width = 20 milliseconds.
•
Generate Continuous Toggle
- This command will generate a continuous toggle of the external GPO port. This toggle will
continue until a

Generate Rising Edge
, or
Generate Toggle
command is received. The rate of toggle is
24Hz. .

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.
