一：备份LDR文件.

  先看LDR文件的保存,这里选择后一般都有提示输入文件名的,如果提示without extension,这个表示不用输入文件的扩展名,系统用默认的.input file name就是输入文件名的意思,这些英文的基本意思大家要搞明白了,最新中文手册上都有的.

二：LDR的使用

    LDR文件的加载是经常做的,下面看看如何加载,LDR文件加载都必须是在正确的固件目录操作的,要不PC3000是找不到的.它只找当然前目录下的,你也可以输入绝对目录,当然最好在当然固件目录下操作就很容易.如果当前目录下有自动会提示文件名,我们只须按键头选择要写的LDR文件就行了.加载成功后一都有成功的提示,不成功就会提示不成功的.不成功的原因有好多,有可能电路板是坏的,LDR文件不一样,都会导致不成功.下面就看看具体过程.
