This data collector is equipped with efficient the ARM kernel, self-created JBFS file system and JBOS operating system which is in possession of independent intellectual property right. This product adopts high strength industrial design and has a high protection level of IP54. The A138 PDA is widely used in the industry of power supply, water supply, logistics, storage, commerce education and library management.
Features
1. This data collection equipment is configured with a high-performance CPU whose dominant frequency is 75MHz. With the efficient processor, our product has a high operating speed with low power consumption.
2. The A138 PDA supports GPRS real-time data transmission. Meanwhile, combining the PC client-side agent software, it can support many other types of real-time data transmission. It supports 433 point-to-point (including multi-point to single point) wireless data transmission thus it can achieve remote data reading.
3. This machine has a high USB data transmission speed which is 200K/s. It helps reduce the waiting time in meter reading or stock taking.
. This data collection machine offers a solution to prevent false meter reading to help achieve scientific management. Through the application of RFID identification tag, this machine helps prevent the behavior that the staff does not go to the data site personally but offers a false meter reading result through subjective reckoning.
5. The protection levels for water proof and dust proof performance of this PDA reach to IP54. With 3mm-thick solid housing in consistent color to protect the internal components, our product will not be damaged if falling down to the ground from the position of 1.5m in height without any protection.
