INTRODUCTION TO SIGNALS
Phantom cameras incorporate multiple hardware signals to interface to external devices.
These are used to drive the camera's frame rate, shutter and trigger, to output to other
devices, to monitor with an oscilloscope, and to import test sensor data using a Data
Acquisition (DAQ) unit.
Ports on Phantom cameras are either fixed, assignable or programmable. Assignable
ports are typically labeled 'Aux' on the connector, and the 'Camera Signals' menu in PCC is
used to select between the 2-3 signals that can be assigned to that port.
Programmable I/O incorporates a pulse processor. In addition to assigning different
signals, the signal characteristics can be modified to better interface with external devices.
In most cases, the signal polarity, filter time, delay, pulse width and edge (rising versus
falling) can be set. Setting these characteristics is referred to as 'Pulse Processor Control.'
Programmable I/O ports can be identified on the camera body with a '/P.' Each port is to be
identified in the PCC 'Camera Signals' menu using the port number. Each one has a default
which will be set after a factory reset or by using the 'signal default' function in PCC.
