Single Chip MODEM for Miniature Embedded POS Machines I. Product Introduction With the development of embedded network technology, networking and remote monitoring of devices have urgently needed to be solved. The embedded MODEM, which is networked through a telephone line, has become a preferred networking product for manufacturers due to its ease of use and small influence from other parties. This product adopts the latest main control chip, uses the third generation of silicon DAA technology to solve the most economical, the industry's smallest size, the lowest power hardware solutions, using two-sided SMD process manufacturing, specifically for remote measurement and control system digital data transmission system The modular products developed can be easily embedded in various industrial communication applications such as various data acquisition and control systems and single-chip remote data communication systems. Second, the application system Remote monitoring system Remote Data Acquisition System Remote fault diagnosis system Finance\tax control system Electric power monitoring equipment Unattended site Remote fire alarm system Hydrology and weather detection system Third, functional characteristics Up to 56Kbps transfer rate Supports ITU-T V.90, V.34, V.32 bis, V.32, V.22 bis, V.22, Bell 212A and 103 data modulation methods.
