4–Read Cycle/Trig-

Read Cycle/Trigger

Chapter Contents

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 typi-

cal operation a bar-coded item moves along a line past a scanner. A sensor or timer

activates a read cycle during which the scanner actively searches for bar code sym-

bols. You will need to decide how to initiate the read cycle and how and when to end

it. This section addresses these issues.

Note: The characters NULL <> and , can only be entered through embedded menus,

not through ESP or serial commands.
