The wireless barcode collector is a very unique wireless barcode scanning product on the market. It combines the functions of a wireless barcode scanner and a simple wireless data collector, and users can use it without any programming. It has a keyboard and a screen, which can realize the functions that the wireless barcode scanner can't realize. For example, when the barcode is damaged and cannot be scanned, it can be input through the keyboard; it can display the currently used wireless channel and battery power. The wireless base station that communicates with the handheld terminal adopts a USB interface, emulating keyboard mode, and can be used without any driver.
It adopts a laser bar code scanning engine with fast scanning speed and large depth of field, which can meet the needs of most industries. At present, most of the laser scanning guns on the market still use 8-bit single-chip microcomputers to complete the decoding, and use the 32-bit ARM CPU that is ten times faster to achieve the decoding, which is faster and more accurate.
It has a simple barcode data collection function. Support offline batch scanning mode, and can scan and save up to 50,000 barcode data at a time. After the collection is over, the user can centrally transmit it to the computer at one time by wireless means. For many simple barcode collection applications, it can directly replace the expensive and complicated inventory machines that were originally used, greatly reducing the user's purchase and use costs.
The wireless frequency used is 433M, two-way communication, and there is a wireless signal strength indicator on the screen. It supports a maximum of 99 wireless channels, which means that 99 groups can be used at the same time without mutual interference; each channel can support a maximum of 255 devices. In practice, because the same channel may conflict, the same channel devices used at the same time should not exceed 10. In the case of unobstructed, the transmission distance can generally reach 50-100 meters; in the case of relatively large interference or need to cross multiple walls, the wireless communication distance may be greatly shortened. The reason why the more widely used Bluetooth transmission is not used is that the Bluetooth transmission distance is very short, generally no more than 10 meters, and Bluetooth uses the ultra-high frequency band of 2.4G, the ability of radio waves to pass through obstacles is much weaker than 433M, and the paired PC side Bluetooth The driver needs to be installed before the device is used, and the operation is more complicated.

13). The wireless base station is paired with the handheld terminal. A base station can be equipped with up to 10 handheld terminals in practical use. The wireless base station adopts USB interface, keyboard simulation mode, and access to WINDOWS without driving. For special applications, the wireless base station can also provide a serial interface to connect to the device.
3. Scope of application
The wireless barcode collector can completely replace the traditional wireless scanning gun. In fact, it is a more powerful wireless scanning gun, but the appearance is different from the traditional wireless scanning gun. It is especially suitable for barcode scanning of logistics, large items and barcode scanning in large warehouses . At the same time, its keyboard and screen provide functions that cannot be achieved by wireless barcode scanners, such as manual barcode input, barcode scanning, and wireless signal strength monitoring. , Battery power monitoring, etc.
The wireless transmission distance is up to 50-100 meters, so it can also be used directly as an inventory device for small supermarkets, small bookstores and small warehouses .
Not only a wireless barcode scanner, it also has simple barcode collection and storage functions. The built-in FLASH memory can store up to 50,000 barcodes at a time. For example, barcode collection of office equipment, clothing inventory, purchase and shipment inventory And other similar applications are also very suitable . Through the wireless batch transfer function, the barcodes collected in batches can be automatically transferred to an Excel spreadsheet, or transferred to a text file so that the data can be imported into the management software.
