Symbol PL4507 Decoder Integration Guide
Theory of Operation
During image capture:
1.
The image sensor array in the Symbol SE4500 captures an image of the bar code through the engine’s optical
lens. If necessary, the engine automatically adjusts illumination, exposure, and other parameters to obtain the
best quality image.
2.
The SE4500 sends the image to Symbol PL4507 decoder board.
3.
The PL4507 processes the image to identify the target bar code(s), decodes them, and transmits the decoded
data to the host.
Set various parameters provided in this guide to adjust the performance of the Symbol SE4500 and PL4507 to
match the application or desired usage profile.
