Auto Trigger Operation - Opticon OPC-3301i Specification Manual

8.9.2. Auto Trigger Operation

The scanner has an optional auto trigger mode in which it starts to read a bar code
automatically when it detects one.
When auto trigger mode is enabled, the scanner tries to detect bars at regular intervals and
when it detects 18 or more bars, it enters read mode in which it tries to decode a bar code.
When the scanner continues to detect bars after the reading has been done, it will assume
those bars are from the same bar code as the previous one and will not attempt to read it.
When the detecting conditions are not met, the scanner will perform the intermittent scanning
again until the next bar code is detected.
