At present, there are many brands of PDA handheld terminals in the domestic market, and there are mixed fish and snakes. When purchasing a PDA handheld terminal, you need to pay attention to: the scope of use, interface, decoding range, price and service items. Do you know a few of these purchase considerations?
First of all, users need to know when purchasing products:
1. What is a PDA handheld terminal? The industrial pda is a terminal device that integrates the bar code scanning device with the terminal and has a battery that can be operated offline.
2. What can a PDA handheld terminal do? With real-time acquisition, automatic storage, instant display, instant feedback, automatic processing, automatic transmission. It has the characteristics of integration, mobility, high performance, small size and light weight.
The following content is the PDA handheld terminal purchase considerations, a total of eight points:
1, the scope of use
Users should choose different handheld terminals according to their different situations.
Taking the warehouse as an example, if the user uses the handheld terminal in a large three-dimensional warehouse, the storage position of the item is relatively high and is far away from the operator, the industrial PDA handset with a large depth of reading and a long reading distance and a high first reading rate should be selected. . For example, the X7 ultra-deep depth-of-sight handheld terminal from Pinbang Technology can seamlessly transition between a target of 0.15 meters and a target of 15 meters (50 feet) at a distance. For users of small and medium-sized warehouses, the requirements in this area are not high, and some hand-held terminals with complete functions and easy operation can be selected. In addition, due to the high frequency of use of the handheld terminal by the warehouse, this requires the optional industrial PDA handset to have high quality and comfortable grip, and can support high-intensity scanning of tens of thousands of times per day.
2, the scope of decoding
The decoding range is an important indicator for selecting a handheld terminal. Most handheld terminals can recognize EAN code, UPC code, etc., or even a dozen different code systems, but there are big differences. In the application of logistics enterprises, we must also consider EAN128 code, Sanjiu code, Kudba code and so on. Users should fully consider the coding range in their actual application when purchasing.
3, interface requirements
The interface capability of the collector is a key consideration when selecting an industrial PDA handset. When purchasing, the user must first specify the operating environment and interface mode of the original system, and then select the handheld terminal that adapts to the operating environment and interface mode.
4, the first reading rate
The first reading rate is a comprehensive indicator of the industrial PDA handset, which has a certain relationship with the printing quality of the bar code symbol, the design of the decoder and the performance of the scanner. The higher the first reading rate, the more work time is saved. At the same time, the higher the first reading rate, the higher the bit error rate. Therefore, when selecting the collector, the user should purchase the handheld terminal that meets the system requirements according to his actual situation, and the first reading rate and the bit error rate are performed. balance.
5, screen resolution
The higher resolution can better support the software, the status display operation interface, and improve the user experience. Appropriate brightness and contrast also protect the operator's vision.
6, protection level
An industrial product with a high degree of protection ensures stable operation in harsh industrial environments without compromising productivity.
7, the price
When choosing a handheld terminal, price is also a concern. The configuration of the handheld terminal is different, the function is different, and the price will vary greatly. Therefore, when purchasing, you should pay attention to the purchase according to the specific needs, not to match the functions that are not used, and truly achieve "good quality and low price."
8, service
Perfect pre-sales and after-sales service is a necessary consideration for selecting industrial PDA handset manufacturers. This ensures that any technical problems and after-sales problems of the purchased handheld terminals will be solved by professional teams to protect the purchased handheld terminals.
