About an output
The output can generate a falling edge, rising edge, toggle or continuous toggle.
• 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 Falling Edge, Generate Rising Edge, or Generate Toggle
command is received. The rate of toggle is 24Hz. .

Image B–2
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 predefined Macros (not editable). Not with the GPIO of the
ICMP-X.
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.
