如题，现在测试的结果，就是RL远端失败，没有一个正确的，不过有一个情况是，模块和线是不同厂家的！和这个有关吗！如果没有关系，还有什么情况，线缆应该是没有问题的，是真线！

<p>肯定产品不匹配 所以引起测试不通过!建议下回用同品牌的东西! 线缆最重要! 你用什么牌子的线!</p>

没有关系的.把资料自己改一下就行了.甲方又不会拿福禄克去测的.

你换一下跳线，或许能解决问题，方便时咱们可以相互学习13203880692（郑州）

要不这样试试：先换一个和网线一个品牌的模块测试看看，如果测试通过的话，那就是产品不匹配的问题，如果还是你说的那种情况的话就不是产品不匹配的问题啦，再另外想办法。

<p>楼主,六类的有可能出现这个问题.</p><p>各个厂家的东西相互之间的匹配性有可能会出现这个问题.这个主要是很多厂家在做自己的模块的时候,是根据线材的性能修改模块的PCB板子的性能,做一些补偿.或者根据模块的匹配问题,修改线材的绞距.以达到最好的效果.</p><p>所以这也造成了很多品牌公司的产品互相之间测试性能偏低,但是出现错误的情况很少.</p><p>建议重新打一下模块,并不是所有的模块的打线方式都是一模一样的.</p>

<p>可以选择去掉那一项，进入setup设置成ISO 11801 Class D NO RL UTP 100 0HM Cat 5 这样就可以通过了。</p><p>正好我昨天测试的时候也遇到和楼主一样的情况，一个都通不过，然后没办法设置了一下，没有测试那个参数就全都pass啦。不过这样好像有点缺德啊，:-)</p>
