pelco-p

1位起始位、8位數據、1位停止位，無校驗位。波特率：9600B/S

1.該協議中所有數值都為十六進位數 2.STX始終為A0H

3.地址碼為攝像機的邏輯地址號，地址範圍：00H–1FH 4.指令碼錶示不同的動作

5.數據碼1、2分別表示水平、垂直方向速度（00-3FH）,在有關預製點的操作時，數據碼2表示預製點值 6.ETX始終為AFH

7.校驗碼(XOR sum of Bytes 2-6) = 位元組2 ^ 位元組3 ^ 位元組4 ^ 位元組5 ^ 位元組6

以地址碼0x01為例：

{0xa0,0x01,0x00,0x08,0x00,0x30,0xaf,0x39,}//上

{0xa0,0x01,0x00,0x10,0x00,0x30,0xaf,0x21,}//下

{0xa0,0x01,0x00,0x04,0x10,0x00,0xaf,0x15,}//左

{0xa0,0x01,0x00,0x02,0x10,0x00,0xaf,0x13,}//右

{0xa0,0x01,0x00,0x40,0x00,0x00,0xaf,0x41,}//變倍短

{0xa0,0x01,0x00,0x20,0x00,0x00,0xaf,0x21,}//變倍長

{0xa0,0x01,0x02,0x00,0x00,0x00,0xaf,0x03,}//聚焦近

{0xa0,0x01,0x01,0x00,0x00,0x00,0xaf,0x00,}//聚焦遠

{0xa0,0x01,0x08,0x00,0x00,0x00,0xaf,0x09,}//光圈小

{0xa0,0x01,0x04,0x00,0x00,0x00,0xaf,0x05,}//光圈大

無命令字發送//燈光關 無命令字發送//燈光開

{0xa0,0x01,0x00,0x96,0x00,0x20,0xaf,0xb7,}//自動巡航

{0xa0,0x01,0x00,0x99,0x00,0x20,0xaf,0xb8,}//關閉自動巡航 {0xa0,0x01,0x00,0x07,0x00,0x01,0xaf,0x07,}//轉至預置點001 {0xa0,0x01,0x00,0x03,0x00,0x01,0xaf,0x03,}//設置預置點001 {0xa0,0x01,0x00,0x05,0x00,0x01,0xaf,0x01,}//刪除預置點001

以上對應的停命令均是（上下左右、變倍、聚焦、光圈均有停命令）: {0xa0,0x01,0x00,0x00,0x00,0x00,0xaf,0x01,}
