通过三星协议控制三星摄像头的菜单，进行快门等调节

        最近做的一个项目，要求根据不同光照度对三星摄像头的快门进行控制，而三星摄像头快门必需通过菜单来进行设置，所以对三星协议进行了一下学习。
        三星协议和PELCO一样，也是一个串行控制协议，其内容如下：

 

SAMSUNG   Protocol

 

 

1. PROTOCOL

  Data Communication :  RS485, Start-Stop Synchronized serial interface

  Protocol :  8bit data ,1 Stop bit, None Parity 

  Transmission speed :  4800, 9600, 19200, 38400 bps

 
2. Data Format

           

                                  9 Byte Fixed

l      ACK is applicable only in case that Byte 4 is 03H

 

"       00H : OK

     01H : Error (Request Retransmission)

#      Camera Mode

-. Manual Mode : 00H

-. Pattern Mode : 02H

-. Scan Mode : 03H

-. Auto Pan Mode : 04H

$  In case of Pattern Mode(Byte6=02H), this byte means Pattern Number (1~3).

 其中MENU命令可打开和关闭菜单；

ENTER对当前命令进行确认；

Numeric Key中的3、9、5、7命令可对菜单光标进行上下左右移动操作。

操作成功后，摄像头会返回正确指令应答。A0 01 00 FF 00 00 00 FF FF等。
