//5A:数据头，为固定字节
//01:表示输出电压极性，这个位置可以出现00，01，02几个数值，01表示输出正电压，02表示输出负电压，00表示输出0V（可用于0电位点校准）。
//09 30：电压数值2字节，09 30表示输出9.30V电压。此数值在00 00～09 99之间，表示0.00V～9.99V电压。这个字节四位数字左边的一位数是无效数字，始终为0，比如，09 30，用户输入成19 30，DAC板接收到数据后会去除掉左边的1，仍然输出为09 30（9.3V）。
//A5:数据尾，为固定字节。
//综上所述：5A 01 09 30 A5这一帧数据表示DAC板输出+9.30V电压。
//注意所有发送的数据都是16进制数据（HEX).
// 板子接受5字节数据后返回2字节DAC数据,以便用户确认通讯正常。例如，发送5A 01 09 30 A5五字节后，返回的2字节数据是09 30
