WRT54G V2.2 加ttl转rs232线[已测试，有图]

scutlxb

搞个这样的线其实是很便宜的东西, 又好用。  关键是通过它可以看到路由哪里有问题。
我自己试验过可以适合 wrt54g v2.2 和belkin 7231-4
下面是以wrt54g v2.2为例：  （belkin 接到路由上面的线序有点不同，论坛搜索7231-4 应该可以找到具体的线序
                         或看这个也可以  http://wiki.openwrt.org/OpenWrtDocs/Hardware/Siemens/SE505）


需要硬件：
1.芯片MAX232      1个 （这个价钱大概2.5元左右吧）  (听说max3232 好一点，不过会贵一点，5元左右吧)
    芯片座         1个
2.电容(0.1μF)    5个   （嗯， 好像 1μF 好点，  其实 0.1~10μF 都是适合的 ）
3.DB9（应该叫Female吧，应该写作DB9F，指的是接到电脑主板com口的另外一头）

你的焊工好差哟

oywl43210

业余的已经很好了

scutlxb

晕死，出现问题了。

显示乱码。。。。。。

怎么解决？

leechange

1.板子上焊排针或者插座，给以后使用带来巨大的方便性；
2.一块232上有可以转两个串口，jp1上也确实把两个串口都引出了，不都用很可惜。

lyy9801318

焊排针或者插座吧，你这样焊接，又不酒精清洗，不出问题才怪。

看看我的：

scutlxb

现在已经搞好了那条线了。
嗯，准备加排针。还有就是芯片加IC座。

现在已经有两条线了。 JTAG线和 ttl转rs232线。

scutlxb

不知什么原因，芯片给我搞坏了。可能焊接过于频繁，有静电。
建议加个IC座。这样就不用直接焊接芯片了。

6.附加一些硬件测试
由于各种的原因，譬如静电等，导致转接线无法使用。通过查看max232的datasheet，
可以看到，芯片如果接Vcc=5V输入时，V+(即第2脚)大概等于2倍Vcc，即10V。
而V-（第6脚）等于 -（V+）。这样可以测试芯片是否正常。

   还有一些对应关系 （max232有两组ttl转rs232），这里列一组，也就是上面采用的
那组。另外一组自己下载max232的datasheet看图。
   TTL       |             MAX232              |      RS232
  4 （发送）|   11（接收）  14（发送） |     2（接收）
6（接收） |   12 （发送） 13（接收） |     3（发送）

楼主华工的？

xiong2209

楼主SecurtCRT在那里下载

xiong2209

我按楼主的做法在SecurtCRT5.13里显示乱码是不是SecurtCRT5.13版本的问题
用恩山的TTL线就可以显示

不一定非要SecurtCRT，直接用windows里带的超级终端就行。位于“开始”-》“程序”-》“附件”-》“通讯”-》“超级终端”

用超级终端也是乱码
