code scanner, also known as the scanner , is a high-tech product that closely combines optical, mechanical, electronic, software application and other technologies. It is the main computer input device after the keyboard and mouse. From direct pictures, photos, films and other drawings to documents, you can use the scanner to input it into the computer to realize information processing, management, use, storage or output. The use of barcode scanners has been widely used. Say goodbye to manual orders. Currently, customers can read the color, style, size and other product-related information of items by scanning barcodes with barcode scanners. The use of code scanning guns greatly improves work efficiency, simplifies work operation procedures, improves item accuracy, and can scan a wide range. How to set up the
barcode scanner driver?
barcode scanner can generally be divided into the following three interfaces, namely USB interface, serial port and keyboard port.
1) USB keyboard management mode: It is somewhat the same as USB keyboard. After connecting the scanner to the computer, in our country, we start to scan barcodes, and we will constantly find that there is data input where the cursor of our computer is. No matter what the software is, as long as the keyboard design can be used as input, local governments can use scanning information to enter system data. USB keyboards do not require drivers, so barcode scanners that are very similar to USB keyboards do not require drivers.
2) USB serial port method: This method is generally used in factories. For some special requirements, serial port transmission can also be selected. This requires a driver, which is a driver, USB is a serial chip, and some of these drivers are divided into 32-bit and 64-bit drivers according to the system. If you want to scan a QR code containing Chinese characters, you must scan it through the serial port. If there is no corresponding software to receive the data, you need some small software to transfer the data received by the serial port to the cursor.
3) USB hidden mode: This mode is similar to USB serial port mode and requires a driver and special software to receive data from the hidden interface.
uses barcode solutions in retail warehousing management. When using a barcode scanner, please pay attention to this: the serial barcode scanner cannot use Notepad, excel, word and other tools. You can use the computer's HyperTerminal (XP comes with the computer Equipped, Windows 7 is not equipped), or download an serial port assistant.
Scanner gun functions and functions:
1. Fast input speed: Compared with keyboard input, barcode input is 5 times faster than keyboard input, and can achieve "instant data input."
2. High reliability: keyboard input data error rate The error rate using optical character recognition technology is one in ten thousand, while the error rate using barcode technology is less than one in one million
3. Large amount of information collected: using traditional one-dimensional barcodes. It can collect information of dozens of characters at a time, and the two-dimensional barcode can carry information of thousands of characters, and has certain automatic error correction capabilities.
4. Flexible and practical: barcode identification can be used alone as a means of identification. It can form a system with relevant identification equipment to achieve automated identification, and can also be connected with other control equipment to achieve automated management. In addition, it is easy to make, has no special requirements for equipment and materials, and the identification equipment is easy to operate and does not require special training, and the equipment is also easy to operate. Relatively convenient.
