Input Specifications
The BOA2 vision system provides three (3) dedicated opto-isolated, polarity
independent inputs. One of the inputs provides the acquisition Trigger function, while
the other two are general purpose.

The active polarity of each input is configured in the iNspect Express application. The
camera includes a noise filter on the input which is also configurable.
To connect with an NPN source, connect the camera trigger input (pin 5) to the NPN
source output and the camera common input (pin 7) to PWR. When the source output
turns ON, the camera input will be pulled down turning the opto-coupler ON.
To connect with an PNP source, connect the camera trigger input (pin 5) to the PNP
source output and the camera common input (pin 7) to GND. When the source output
turns ON, the camera input will be pulled up turning the opto-coupler ON.
