Scan Window
The replaceable scan window allows laser light to exit the Reader.
Light reflects off the bar code symbol, passes back through the scan
window and is decoded by the Reader. The scan window can be
replaced with a glass or plastic window. See page 1–18 for details
on replacement window kits.
Configuration Port Connector
The RS-232 port allows a personal computer running the
AdaptaScan Software (Catalog No. 2755-ASN) to download a
configuration to one or more Readers.
The Configuration Port Connector is for temporary use during
configuration transfers and system setup.
