在http://forums.ni.com/ni/board/message?board.id=30&message.id=216&requireLogin=False 的帖子中，NI的工程师说：
“It is possible to use our Low-Speed CAN boards in
a single-wire mode. However, the board will give CAN warnings. So, the
control program may have to ignore certain CAN warnings.

但是没有给出具体的硬件连接方法和软件设置。
是否直接把USB8472的PIN 7接到Single Wire CAN，USB8472的PIN9和PIN3接电源的正负极就可以了。软件的编程上不需作其它设置吗？上述的帖子中提到的CAN warnings在什么时候出现？
