How to set the specified two-dimensional code scanning software or scanner gun, it is difficult to estimate, only in your software inside the gun SN bind with your software, and then only through the two-dimensional code encryption, then your software decryption, so that only the gun you provide to correctly display the bar code content in your software in a little two-dimensional code first official definition: also known as two-dimensional bar code, which is used according to certain rules specific geometry in the plane (two-dimensional direction) on the distribution of graphic black and white, is a key to all the information of the data. saying that white is the key to achieve passage of a connection, as if to drive you have to have the key, in order to drive home you need to have a key to open the door. For the manufacturer, the two-dimensional code is a channel for them to let customers know that a company's products, a marketing tool in Baidu enter two-dimensional code production, making two-dimensional code can be downloaded software, it is simple to operate, each software production process is not the same, there is no particular accurate answer, follow the software prompts on the line using two-dimensional code is very flexible, for example, two-dimensional code can be printed on color pages, on business cards, all kinds of beneficial to the promotion of local, The most common method is to use: for example, a cosmetics company to do the activities, the door will have a few great color pages, on the above it is clear that companies will be printed on a two-dimensional code, and business representatives will say, scanning two dimensional code and focus on the opportunity to enjoy the discount award, and so on. After scanning the two-dimensional code will be connected to the pre-set content, this content settings are producing two-dimensional code background operation, and some businesses will set the connection is sites, some of them are some of the activities notice, some companies introduced two-dimensional code Do not think too short too difficult, in fact, as long as you make a two-dimensional code to download a software, you will know to understand the two-dimensional code, making a two-dimensional code is very simple, just the way the method used will take into account the effect of corporate marketing considering it. barcode scanner settings here we mainly analyze the manual can be achieved through the scanner settings that scanner function, barcode scanner settings via PC software on the other part of the description. 3.1 restore factory settings this setting is barcode scanner settings of the most important settings, barcode scanner malfunction under normal circumstances (if you can not read the bar code, etc.) are available through this barcode scanner settings to solve problems. prefixes and suffixes added 3.2 yards data set some applications require barcode reader barcode data upload has certain prefixes and suffixes to adapt some of the functionality of the system, through the barcode scanner settings for the bar code can be easily scanner add prefixes and suffixes. 3.3 yards bits of data interception set up some applications require barcode reader barcode data upload deleted after the first few characters or a few characters to adapt some of the functionality of the system, through barcode scanning settings, you can easily be a character-digit bar code scanner for deletion. 3.4 yards scanner can set the number of serial communication produced by the barcode scanner settings, convenient serial port parameters have to be modified, such as baud rate, parity experience, stop bits, data bits, handshake agreements. 3.5 yards scanner to scan mode settings present high-quality barcode scanner can scan a variety of ways, such as a manual push-button scanning, scanning light lit, the light flashes scanning, inductance barcode scanning, you can set this barcode scanner to easily switch between various modes. 3.6 yards scanner code system opening set barcode scanner how to set barcode scanner in order to accelerate its decoding speed, often Some support barcode symbologies were locked by default scanner can not read, if the actual encounter this type of lock bar code, bar code scanner can be set by this conduct code system for quick and easy opening. 3.7 yards scan When the interface type is set to be replaced when the bar code scanner data line interface, you can set this bar code scanners, conversion interface mode, so that the bar code scanner can be used normally in the interface mode. 3.8 yards scanner buzzer When the bar code scanner is set in a noisy and quiet in the alternate use, you can set this bar code scanners, bar code scanner to scan the size of vocal control, to better suit the requirements of sound related products recommended:.
