Read cycles and triggering modes are at the heart of bar code scanning. After you've
established communications and completed basic read rate testing, you will need to
address the spatial and timing parameters associated with your application. In a typical
operation a bar coded item moves along a line past a scanner. A sensor or timer acti-
vates a read cycle during which the scanner actively searches for bar code symbols. You
will need to decide how to initiate the read cycle and how and when to end it. This sec-
tion addresses these issues.
Note: The characters NULL <> and
not through ESP or serial commands.
