I. Product introduction.
1, features PDT-7A wireless barcode scanner is a very humanized design of a wireless barcode scanning products on the market, it has a color screen and key manual input function. It has color screen and key manual input function. If the barcode is damaged and can not be scanned, it can be input through the keyboard; it can display the barcode characters, barcode type, scanning transmission or storage status, real-time clock, wireless signal strength, the current wireless channel and battery power. The wireless base station communicating with the handheld terminal adopts USB interface and emulates the keyboard mode, which can be used without any driver program.
The PDT-7A utilizes a laser barcode scanning engine that provides fast scanning speeds and a large depth of field to meet the needs of most industries. The majority of wireless laser scanners on the market still use an 8-bit microcontroller to complete the decoding process, while the PDT-7A uses a 32-bit ARM CPU that is ten times faster to realize the decoding process, making the decoding process faster and more accurate.
Supporting offline batch scanning mode, PDT-7A can scan and save up to 100,000 barcode data at a time. After the acquisition, users can transfer the data to the computer or generate the acquisition file through the USB data cable by wireless mode. The communication mode is more flexible and convenient, suitable for all kinds of applications.
Using the wireless frequency of 433M, two-way communication mode, the screen has a wireless signal strength indication. It supports up to 32 wireless channels, which means it can be used by 32 groups at the same time without interfering with each other; each channel can support up to 255 devices, and in practice, due to the conflict that may arise from the same channel, it is best not to use more than 10 devices with the same channel at the same time. In the case of no obstruction, the transmission distance can be up to 50-100 meters; in the case of more interference or need to cross multiple walls, the wireless communication distance may be greatly reduced. PDT-7A does not use the more widely used Bluetooth transmission is because the Bluetooth transmission distance is very short, generally less than 10 meters, and Bluetooth 2.4G UHF band, radio waves through the obstacles than the ability to 433M a lot weaker, and at the same time, paired with the PC side of the Bluetooth device needs to be installed before the use of the driver, the operation of the more complex.

3. Appearance and accessories.
Wireless barcode scanner contains two parts: handheld and wireless base station.
4, the scope of application.
PDT-7A wireless barcode scanner is the latest generation of wireless scanner, in fact, it is a more powerful wireless scanner. Especially for data security requirements are very high, the data information to understand the time to view and batch collection of bar codes and the use of harsh environments in large warehouses bar code scanning, at the same time, its keyboard and screen provides a wireless bar code scanner can not be realized functions, such as manual input bar code, scanning bar code to view the intensity of the wireless signal to monitor the battery power to monitor and so on.
The wireless transmission distance is up to 50-100 meters, so it can also be used directly as a communication device for small supermarkets, small bookstores and small warehouses.
Not just a wireless barcode scanner, it also has barcode collection and storage functions, the built-in FLASH memory can store up to 100,000 barcodes at a time, for example, office equipment barcode collection, apparel, inbound and outbound collection of barcodes is also very suitable for applications. Through the wireless batch transfer function, the barcode collected in batch can be automatically transferred to an Excel spreadsheet, or to a text file for data import to management software
The first step is to start using it.
1. Battery and charging.
The handheld is powered by a built-in 1200MAH rechargeable lithium battery, which can guarantee 500-1000 charges. With the built-in charge management function, you can charge the Li-ion battery through the USB charging port at the bottom of the handheld. Charging voltage is 5V, the user can directly use the computer's USB port charging, can also be charged through the external 5V power supply, the handheld will automatically monitor the charging status, full charge automatically shut down. It can work continuously for 30-50 hours after a full charge. When charging, the red indicator light will be on; when the red indicator light is off, it means it is fully charged. When charging, it is better to turn off the handheld.
2. Power on and off.
The red button is the power button. After powering on, the scanner will revert to the interface before powering off.
