BOA Outputs
The BOA has three outputs, Strobe, GPO0 and GPO1. Driver source, Polarity, Offset, Duration,
and Initial value.
BOA Outputs Configuration
Driver selects what controls the output:
Script Setting the output is controlled by equations or statements in the Scripting language.
This value disables the other fields in the row.
Pass Pulse an active pulse is output when the inspection result is Pass.
Recycle Pulse an active pulse is output when the inspection result is Recycle.
Fail Pulse an active pulse is output when the inspection result is Fail.
Strobe Pulse (GPO1 only) pulse is output after a trigger input. The pulse uses the settings in
this panel (not the light output settings in the Sensor Setup panel).
Polarity select active high or active low for the output pulse.
Pulse Offset enter a value for delaying the output pulse, to synchronize to external equipment.
Pulse Duration enter a value for the output pulse width.
Initial Value enter a value for the state or value of the output when the solution is loaded.
Please Note: If you select a Pass, Fail, or Recycle pulses, the pulse output is relative to the trigger
input. The offset must be long enough to allow the inspection to complete, otherwise only a fail
pulse will be output (if a fail pulse is selected).
Minimum Pulse Offset = Exposure Time + Acquisition Time + Inspection Time
Runtime overhead (such as displaying images) can also affect the minimum pulse offset require-
ment. You should examine or calibrate this time based on your typical use of the system.
