Input Specifications
The BOA vision system provides two dedicated opto-isolated, polarity independent
inputs. One of the inputs provides the acquisition Trigger function, while the other is
general purpose.

The active polarity of each input is configured in the Sherlock Embedded Client
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 1) to the NPN
source output and the camera common input (pin 5) 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 1) to the PNP
source output and the camera common input (pin 5) to GND. When the source output
turns ON, the camera input will be pulled up turning the opto-coupler ON.
