PELCO-D与PELCO-P基本协议(不包括扩展协议)中文解析
PELCO-D:

  数据格式:1位起始位、8位数据、1位停止位,无效验位。波特率:2400B/S
  命令格式:
 
字节1
 字节2
 字节3
 字节4
 字节5
 字节6
 字节7
 
同步字节
 地址码
 指令码1
 指令码2
 数据码1
 数据码2
 校验码
 


  1.该协议中所有数值都为十六进制数
  2.同步字节始终为FFH
  3.地址码为摄像机的逻辑地址号,地址范围:00H–FFH
  4.指令码表示不同的动作
  5.数据码1、2分别表示水平、垂直方向速度(00-3FH),FFH表示“turbo”速度
  6.校验码 = MOD[(字节2 + 字节3 + 字节4 + 字节5 + 字节6)/100H]
  以地址码0x01为例:
  {0xff,0x01,0x00,0x08,0x00,0xff,0x08,}//上
  {0xff,0x01,0x00,0x10,0x00,0xff,0x10,}//下
  {0xff,0x01,0x00,0x04,0xff,0x00,0x04,}//左
  {0xff,0x01,0x00,0x02,0xff,0x00,0x02,}//右
  {0xff,0x01,0x00,0x20,0x00,0x00,0x21,}//变倍短
  {0xff,0x01,0x00,0x40,0x00,0x00,0x41,}//变倍长
  {0xff,0x01,0x00,0x80,0x00,0x00,0x81,}//聚焦近
  {0xff,0x01,0x01,0x00,0x00,0x00,0x02,}//聚焦远
  {0xff,0x01,0x02,0x00,0x00,0x00,0x03,}//光圈小
  {0xff,0x01,0x04,0x00,0x00,0x00,0x05,}//光圈大
  {0xff,0x01,0x00,0x0b,0x00,0x01,0x0d,}//灯光关
  {0xff,0x01,0x00,0x09,0x00,0x01,0x0b,}//灯光开
  {0xff,0x01,0x00,0x07,0x00,0x01,0x09,}//转至预置点001
  {0xff,0x01,0x00,0x03,0x00,0x01,0x05,}//设置预置点001
  {0xff,0x01,0x00,0x05,0x00,0x01,0x07,}//删除预置点001
  以上对应的停命令均是:
  {0xff,0x01,0x00,0x00,0x00,0x00,0x01,}//停命令
PELCO-P:
  数据格式:1位起始位、8位数据、1位停止位,无效验位。波特率:9600B/S
  命令格式:
字节1
 字节2
 字节3
 字节4
 字节5
 字节6
 字节7
 字节8
 
STX
 地址码
 指令码1
 指令码2
 数据码1
 数据码2
 ETX
 校验码
 


  1.该协议中所有数值都为十六进制数
  2.STX始终为A0H
  3.地址码为摄像机的逻辑地址号,地址范围:00H–1FH
  4.指令码表示不同的动作
  5.数据码1、2分别表示水平、垂直方向速度(00-3FH),在有关预制点的操作时,数据码2表示预制点值
  6.ETX始终为AFH
  7.校验码(XOR sum of Bytes 2-6) = 字节2 ^ 字节3 ^ 字节4 ^ 字节5 ^ 字节6
  以地址码0x01为例:
  {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,}//变倍短
  {0xa0,0x01,0x00,0x20,0x00,0x00,0xaf,0x21,}//变倍长
  {0xa0,0x01,0x02,0x00,0x00,0x00,0xaf,0x03,}//聚焦近
  {0xa0,0x01,0x01,0x00,0x00,0x00,0xaf,0x00,}//聚焦远
  {0xa0,0x01,0x08,0x00,0x00,0x00,0xaf,0x09,}//光圈小
  {0xa0,0x01,0x04,0x00,0x00,0x00,0xaf,0x05,}//光圈大
  无命令字发送//灯光关
  无命令字发送//灯光开
  {0xa0,0x01,0x00,0x96,0x00,0x20,0xaf,0xb7,}//自动巡航
  {0xa0,0x01,0x00,0x99,0x00,0x20,0xaf,0xb8,}//关闭自动巡航
  {0xa0,0x01,0x00,0x07,0x00,0x01,0xaf,0x07,}//转至预置点001
  {0xa0,0x01,0x00,0x03,0x00,0x01,0xaf,0x03,}//设置预置点001
  {0xa0,0x01,0x00,0x05,0x00,0x01,0xaf,0x01,}//删除预置点001
  以上对应的停命令均是(上下左右、变倍、聚焦、光圈均有停命令):
  {0xa0,0x01,0x00,0x00,0x00,0x00,0xaf,0x01,}
