基于C8051F330复印机输稿器通信测试系统设计

Design of the Test System for ADU Communication Based on C8051F330 Copier ADU

介绍了复印机部件输稿器的结构及工作原理,简述了输稿器与主机的通信原理,并利用逻辑分析仪、复印机和单片机组成通信测试系统对其进行测试,将测试结果与经验通信过程数据格式相比较,得出该通信过程类似于串行通信的结论,最后提出用单片机模拟该通信过程的方案。

This paper introduces the working principle of copier＇s additional component ADF （automatic document feeder） and the communication theory between the host system and the ADU briefly. The process of the communication is tested by the test system which is composed of the logic analyzer and copier. Comparing the results to the data formats involved the communication, it is coneluded that the communication is similar to the serial communication. Finally, a scheme that can imitate the communication with microcontroller is proposed.
