19.7 GP OUTPUT INTERFACE
Inputs
The Falcon 50 provides a general purpose output (GPO) interface for signalling or
controlling external equipment. The pinout for the GPO connector (DB15 – Male)
is provided in the following chart. All inputs and outputs are opto-isolated for
reliable operation in a variety of electrical environments. There are four outputs.

Each optoisolator is capable of sinking up to 60 mA of current.
OUTPUTS # 1 AND # 2 can be associated to a variety of events (Temperature exceeding 60 or 70 Celsius
Degrees, Failures one audio inputs, etc) in order to provide ALARM signallings to external devices by means
of Contact closures. Ref. to the User Manual – PART TWO
OUTPUTS # 3 AND # 4 are directly driven via software from external controlling devices or systems (such as
automated radio systems) running a suitable Remote Control protocol.
