B.1 About General Purpose Inputs & Outputs
(GPIO)
The Barco Cinema Controller and the Barco ICMP-X are equipped with GPIO ports. The electrical
specifications described in this chapter are the same for both GPIO ports.
General Purpose inputs
The Barco Cinema Controller and the Barco ICMP-X have each eight (8) opto-isolated general purpose inputs
available. These inputs are used to trigger the execution of macro files. 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
min
= +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 configuration 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-X 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.
