A.General

This CCD Bar Code scanner module is well designed withhigh quality components. The improved digitizer provides very accuratebarcode scanning signal to decoders. With different scanning ranges, It¡¦s ideal to meet the application requirement. Because ithas the compact and small dimensions, integrating this module to most ofhousings is a easy job. It simplifies the developmentprocess and can save developing time. The TTL output allows the scanner moduleto be universally accepted by most decoders.

Thebuilt-in decoder is an advanced and versatile decoding facility for bar codingsystems. It works with variety of bar code types and computer interfaces.

¬ Compact Size

Convenient fit in most of housing

¬ Single 5 Volts Power Supply

Simplified connection to one input power source

¬ TTL Signal Output (TTL version)

Standard signaling for connecting to most decoders

¬ Low Distortion in TTL Signal Output

Easy to decode with most decoders
