2、0xKK,0xa90xb6,0xb6,0xb6,0xSS,0x11,0x05,0xPP,0xa9输出20xb6,0xb6,0xb6,0xSS,0x10,0x06,0xKK,0xa90xb6,0xb6,0xb6,0xSS,0x11,0x06,0xPP,0xa9输出30xb6,0xb6,0xb6,0xSS,0x10,0x07,0xKK,0xa90xb6,0xb6,0xb6,0xSS,0x11,0x07,0xPP,0xa9输出40xb6,0xb6,0xb6,0xSS,0x10,0x08,0xKK,0xa90xb6,0xb6,0xb6,0xSS,0x11,0x08,0xPP,0xa9

3、输出50xb6,0xb6,0xb6,0xSS,0x10,0x09,0xKK,0xa90xb6,0xb6,0xb6,0xSS,0x11,0x09,0xPP,0xa9输出60xb6,0xb6,0xb6,0xSS,0x10,0x0A,0xKK,0xa90xb6,0xb6,0xb6,0xSS,0x11,0x0a,0xPP,0xa9输出70xb6,0xb6,0xb6,0xSS,0x10,0x0B,0xKK,0xa90xb6,0xb6,0xb6,0xSS,0x11,0x0b,0xPP,0xa9输出80xb6,0xb6,0xb6,0xSS,0x10,0x0C,0xKK,0xa90xb6,0

4、xb6,0xb6,0xSS,0x11,0x0c,0xPP,0xa9输入输出增益数据包输入A0xb6,0xb6,0xb6,0xSS,0x12,0x01,0xRR0xa9输入B0xb6,0xb6,0xb6,0xSS,0x12,0x02,0xRR0xa9输入C0xb6,0xb6,0xb6,0xSS,0x12,0x03,0xRR0xa9输入D0xb6,0xb6,0xb6,0xSS,0x12,0x04,0xRR,0xa9输出10xb6,0xb6,0xb6,0xSS,0x12,0x05,0xRR,0xa9输出20xb6,0xb6,0xb6,0xSS,0x12,0x06,0xRR,0xa9

5、输出30xb6,0xb6,0xb6,0xSS,0x12,0x07,0xRR,0xa9输出40xb6,0xb6,0xb6,0xSS,0x12,0x08,0xRR,0xa9输出50xb6,0xb6,0xb6,0xSS,0x12,0x09,0xRR,0xa9输出60xb6,0xb6,0xb6,0xSS,0x12,0x0A,0xRR,0xa9输出70xb6,0xb6,0xb6,0xSS,0x12,0x0B,0xRR,0xa9输出80xb6,0xb6,0xb6,0xSS,0x12,0x0C,0xRR,0xa9说明：①数据包总共7个字节的数据，需要通过串口以16进制的形式连续到机器发送（

6、TTL电平）。②上表中哑音数据包中的0xKK值为0x01表示哑音，0x02表示非哑音。③上表中信号源选择数据包中的0xPP意义如下：0x00：无输入源0x01：INA0x02：INB0x04：INC0x08：IND0x03：INA+INB0x05：INA+INC0x09：INA+IND0x06：INB+INC0x0a：INB+IND0x0c：INC+IND0x07：INA+INB+INC0x0b：INA+INB+IND0x0e：INB+INC+IND0x0d：INA+INC+IND0x0f：INA+INB+INC+IND④如果向机器发送了一帧表1中的数据包，如果收到0x88,

7、0x88,0x88,0xf8表示操作成功，为保证正常通信，请在收到操作成功数据包后才发送下一帧数据包。⑤如果向机器发送了一帧表1中的数据包，机器1秒钟内无回应或者回应0xbb,0xbb,0xbb,0xf8请检查线路连接或者检查数据包是否正确。⑥上表中数据包中的0xSS值表示机器的设备ID。⑦上表中输入输出数据包中的0xRR值为0x01表示音量加，0x02表示音量减。（2012-06-28）新增：输入输出增益数据包输入与输出0xb5,0xb5,0xb5,0x01,0x13,0xTT,0xMM,0xMM,0
