B.1 About General Purpose Inputs & Outputs (GPIO)
The Barco Cinema Controller and the Barco ICMP are equipped with GPIO ports. The electrical speci
fi
cations
described in this chapter are the same for both GPIO ports.
General Purpose inputs
The Barco Cinema Controller and the Barco ICMP have each eight (8) opto-isolated general purpose inputs available. These inputs
are used to trigger the execution of macro
fi
les. For more explanation about the association of a macro to a GPI, consult the user
guide of the Communicator.
Input voltage
The inputs can be directly driven from a TTL or CMOS output.
•
The shape of the pulse must be rectangular.
•
The duration of the pulse must be at least 50 milliseconds (shorter pulses are considered as a switch bounce)
•
Minimum voltage : V

= +5V

Maximum voltage : V

= +18V
External power supply
When interfacing with contact closure outputs, an external power supply needs to be provided. Depending upon the con
fi
guration a
suitable pull-up resistor needs to be added as well.

Cables
When long cable connections are required the use of shielded cables with twisted pairs is recommended. One twisted pair is to be
assigned to each GP Input pair.
How to make the connection
When the power supply used to provide the DC voltage is isolated from ground (for example in the case of an AC adapter) it is
recommended that the minus pole of that power supply is connected to ground (or to the projector chassis). This will avoid high
common mode voltages at the projector GP Inputs. If that same power supply is used for other parts of the system, take care not to
create ground loops. In any case when shielded cables are used that shield should be connected to the projector chassis.
General Purpose outputs
The Barco Cinema Controller and the Barco ICMP have each eight (8) opto-isolated outputs available. Four (4) of the outputs on
the Cinema Controller are dedicated for TI. The other general purpose outputs can be controlled via software.
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

command is received. The rate of toggle is
24Hz. .
