Scanner Parameters
Trigger
The Trigger is the event that initiates a read cycle.
Note: When calibrating the scanner or testing read rate, the current trigger setting will be
disregarded.
Trigger Mode
Continuous Read
Continuous Read is useful in testing symbol readability or scanner functions. It is not
recommended for normal operations.
In Continuous Read, trigger input options are disabled, the scanner is always in the read
cycle, and it will attempt to decode and transmit data for every symbol. If a single symbol
stays within read range for multiple read cycles, its data will be transmitted repeatedly until
it leaves the read range.
The scanner sends replies to serial commands that require responses when symbol data
is transmitted, or read cycle timeout is enabled and a timeout occurs. Depending on the
combination of enabled symbologies and the Threshold Mode setting, the scanner may
take longer than the timeout to process symbol data.
Note: When to Output and No Read options have no affect on Continuous Read.
