摘要
介绍运用单片机MSP430F169控制CMX865A,利用串行总线实现远程数据传输系统,探讨了利用电话线直流馈电给调制解调器供电的可行性,设计并实现了电话线供电的调制解调器。测试结果表明,该系统能够实现信号在网络中的正确传输,可广泛应用于数据采集、控制等各个领域。
The data are transmitted and received by the CMX865A via a simple high speed serial bus which is compatible with most types of host μC serial interface. The possibility of powering MODEM with the phone line is discussed. The phone line powering MODEM is designed and implemented. The experimental result demonstrates that signals can be transmitted correctly. The system can be applied in the information collection field, control field and many other fields.
