This circuit board can translate impulse signal outputted from photoelectric sensor into ASCII codes and then input them into serial interface of the computer, these ASCII codes are ulteriorly displayed and disposed through the CAT software.

• 该电路板可将光电传感器输出的脉冲信号转换成 ASCll码输入到计算机串o，进一步通过相应的CAT软件进行显示与数据处
