Barcode Scanner with RS232 Interface

This is a cost-effective handheld laser RS-232 bar-code scanner, which is special designed for small stores, exclusive shops and chain business organisations. It has a good performance of shock resistance. It fast scan most commonly–used 1D bar codes. Its scanning speed can be up to 150 times/sec and the depth of scan field can be above 40cm.

Want to interface Barcode scanner to Micro-Controller?

Integrating Barcode scanner into your Micro-controller based project has never been simpler. This Barcode scanner has direct RS-232 output so it can be directly interfaced directly to any micro-controller via MAX232 IC. Since the output of the bar-code scanner is serial it can be connected to any micro-controller with UART pins. The default baud-rate is 9600 you can even test the output by connecting it to PC via Serial Port or you can even use a USB to Serial converter (for Laptops & PC's that do not have com port) and view the output on Hyper-terminal by setting its baud-rate to 9600.
