Guangzhou State Association, state licensing 128 silver machine, silver machine provided by the Guangzhou State Association. We are Guangzhou City State Association Information Technology Co., Ltd. (www.gzdb899.com) located: Guangzhou specializes in: cash register, scanner, bar code machines, management software, small ticket machines, cash registers, cash registers shredders Troubleshooting principle cash registers as high reliability products state licensing 128 silver machine, its occurrence is low probability of failure. However, due to changes in the external power supply or external environmental changes caused by product failure, may also be because of a serious collision handling, causing hardware failure, but the situation is the failure of the hardware itself is still relatively small. Therefore, when the POS machine failure, should be based on "first soft and hard, the outside after the first" "fault determination and the principle of exclusion, specifically that: (1) First check the system software, application software, if there is a problem (2) Inspection Outreach cable is connected properly, the external device is correct (if the network fails, check network cable is normal, the switch is normal) (3) should be used to determine faults alternative, which precludes the use of various components of the normal equipment of suspicious (for example: test network cable Easy Exhibitor K2000 supermarket POS cash register, the device can be used to test the network cable is normal normal) (4) device hardware failure (failure especially in the power section, emitting a smell or significantly abnormal sound), first off electrical inspection, only the exclusion of all possible apparent reason (short circuit burned parts, etc.), in order to increase the electrical inspection. (5) determine the host interface or peripheral fault, CHECK.EXE test run should be run in pure dos. (6) Test the keyboard port equipment should be carried out under pure dos. electronic cash registers in English called Electronic Cash Register that referred ECR. the world's first electronic cash register by the United States of 詹敏斯, Liddy and John , Liddy brothers manufactured in 1879 of its functions can only do business in cash, data entry of water to prevent the operator cheating. development of electronic cash registers in the 90s of the last century Easy Exhibitor K1000 silver machine, through improved appeared in print, and can manage input Chinese trade names and simple inventory of electronic cash registers, but due to the limitation of silver machines, electronic cash registers at the time of the CPU resources function is extremely limited. With the development of science and technology, ARM cores are widely used in the CPU, Kawasaki seize this opportunity to launch a central processor with Philips LPC2220 for a new generation of electronic cash registers in 2006. in function to subvert the traditional concept of ECR, developed a set of business management, import and sale, storage, promotions, discounts, bundling, membership management, at any time reports, statistics and other functions in one of the electronic cash registers. also has a restaurant on the Founding and Taiwan, turntable, ordering, package with other functions, let ECR POS machines have a commercial function.
