A. General

This CCD Bar Code scanner module is well designed with high quality components. The improved digitizer provides very accurate barcode scanning signal to decoders. With different scanning ranges, It’s ideal to meet the application requirement. Because it has the compact and small dimensions, integrating this module to most of housings is a easy job. It simplifies the development process and can save developing time. The TTL output allows the scanner module to be universally accepted by most decoders.

The built-in decoder is an advanced and versatile decoding facility for bar coding systems. 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
