Triggered Capture - Microscan QX Hawk User Manual

Read Cycle

Triggered Capture

When set to trigger captures mode the imager operates in the following manner:
• The number of captures represents the number of triggers expected from the system
per read cycle. The first trigger enters the read cycle.
• Subsequent triggers initiate captures in the read cycle up to the number of captures is
met or the end of read cycle condition is met. Any additional triggers between reaching
the number of captures and meeting the end of read cycle requirements will be ignored.
• If the read cycle is fully qualified prior to reaching the number of captures and the symbol
output is set to ASAP, the symbol data will be output and all post processing (Logic
outputs, video, etc.) will finish but the imager will remain in the read cycle. When enough
triggers come in to satisfy the number of captures setting or a timeout expires, the
imager will exit the read cycle. This operation would be synonymous with level triggered
read cycle waiting for the trigger to fall.
• If the end of read cycle is set for new trigger and the read cycle qualifications have not
been met, the read cycle will exit upon receiving the first trigger after reaching the number
of captures setting. At this time the post processing from the read cycle will complete
and a new read cycle will begin.
