Continuous Read
Usage:
Continuous Read is useful in testing symbol readability or reader functions.
It is not recommended for normal operations.
Definition:
In Continuous Read, trigger input options are disabled, the Imager is
always in the read cycle, and it will attempt to decode and transmit every
capture. 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 Imager sends replies to serial commands that require responses when
symbol data is transmitted, or read cycle timeout is enabled and a timeout
occurs and at least one captured image has been processed. Depending
on the combination of enabled symbologies and the Threshold Mode setting,
the Imager may take longer than the timeout to process a captured image.
Note: When to Output and No Read options have no affect on Continuous
Read.
