光纤传输 RS232/RS485信号的 CPLD 实现
Transmitting RS232/RS485 signal via fiber achieved by CPL
摘要
Abstract
In the article, a convert-system is designed base on CPLD, which modulates the RS232/RS485 sig-nal in QDPSK, and converts it to optical signal, then transmits the signal via optical fiber, so that the system achieves the long-distance communication of RS232/RS485. It can be seen from the result of the experimental test and field operating that the system has a good performance, and can be a solution of the long-distance communication of RS232/RS485.关键词
