PDA Selection Criteria

         1, Memory Capacity: Industrial level PDA memory capacity determines the data capacity, its memory capacity and CPU processing speed corresponds to. If the use of low performance CPU PDA, blindly improve their memory capacity, will increase the user's use of processing, waiting time.PDA

         2, coding range: Industrial level PDA can recognize EAN code, UPC code and other more than 10 different codes, but there is a great difference. In the Logistics enterprise application, but also consider EAN128 code, 39 yards, Kudba code and so on. Users should take full account of the coding range in their actual application when choosing.

         3, the first reading rate: users should choose according to the actual situation in accordance with the system needs of industrial-level PDA, in the first reading rate and BER between the two balance. The first reading rate is a comprehensive index of industrial grade PDA, which has a certain relationship with the printing quality of barcode symbol, the design of decoder and the performance of scanner. The higher the first reading rate, the more saving working time. At the same time, the higher the first reading rate, the better the BER.PDA

         4, protection level: a higher level of protection to ensure that the PDA in the harsh industry environment stable operation, to ensure efficiency.

         5, screen resolution: higher resolution can better support the software, in the best state to display the operating interface to enhance user experience. The appropriate brightness and contrast of the operator's eyesight also has protection.PDA

         6, interface requirements: Users in the choice to clear the operating environment, interface mode, and so on, choose to adapt to the operating environment and interface mode of PDA.

         7. Communication ability: As an extension of computer network system, the data collected by industrial PDA and the result of processing are exchanged with computer system. At present, the use of infrared communication PDA transmission data, without any plug parts, reduce the likelihood of failure, improve the product life.PDA
