相机RS232协议

[英]Camera RS232 Protocols

原文 2010-01-31 05:17:46 8 1 camera/ serial-port/ protocols/ pelco

I am looking for information on camera RS232/RS485 protocols. 我正在寻找有关相机RS232 / RS485协议的信息。 The camera I have lists its supported protocols as: 我拥有的相机列出了其支持的协议：

Pelco D 佩尔科D
Pelco P 佩尔科
Fastrax Fastrax
Command 命令

I don't think that Pelco has the features I need but I can't find any information on the last two. 我认为Pelco没有我需要的功能，但是我找不到关于最后两个的任何信息。 Pelco only appears to allow differential changing of zoom and focus (commands to move in/out from current position) but I need to be able to actually SET a value say between 0 and 65535, and also READ the current value. Pelco似乎只允许差异缩放和聚焦（命令从当前位置移入/移出），但我需要能够实际设置一个介于0到65535之间的值，并且还要读取当前值。

In fact, I would purchase a completely new camera if I knew it would support the features I need at an afforable ( 实际上，如果我知道该相机可以支持我所需的功能（如果可以的话），那么我将购买一台全新的相机（

Any more knowledgeable programmers have some advice on these protocols? 还有更多知识渊博的程序员对这些协议有什么建议吗？

Default Pelco protocol definition does not appear to support this feature. 默认的Pelco协议定义似乎不支持此功能。 Contacting vendors directly will sometimes help as different vendors will implement custom protocols. 直接联系供应商有时会有所帮助，因为不同的供应商将实现自定义协议。 However, there does not appear to be a unified definition anywhere to get/set camera positions. 但是，似乎没有统一的定义可以获取/设置相机位置。
