   2          系统接线(适用于台式系统)：
   3          1、试验箱（台）上的CS244接CS0,244的输入IN0--IN7接平推开关KK1--KK8的输入K1--K8
   4          2、试验箱（台）上的CS0809接CS2，模块上的TEMP_OUT接0809的输入ADIN0，
   5          3、CPU板上的P15接模块上的HEATER.
   6          实验说明：
   7            全速运行程序后，通过与244输入端相连的8个平推开关kk1---kk8设置设定温度,
   8          并在数码管的左两位显示（10进制），此数值的设定范围为0--79。同时在数码管的右两位显示实际温度，
   9          认真观察数码管的右两位数值的变化，可以了解温度的控制过程。
