机器为创新的AP,只有一个有线口;
路由器上TTL针的接口
|---------- ----------|
| 1 2 3 4 |
|-----------------------|
用万用表测试针的电压
1和4连接,电压3.23V;4为正,1为负
3和4连接,电压3.36V;4为正,3为负
1和2连接,电压3.23V;2为正,1为负
2和3连接,电压3.36V;2为正,3为负
GND接在1号口上;路由TX为2,线上的RX接在上面有输出;路由RX为4,线上的TX连接上可以输入.
线是好的,用串口调试助手可以正常看到信号传输
SecureCRT的设置:
接通电源启动路由后,可以看到信息输出,但是到:wl0.1: Invalid argument不动了,只有按回车或者ctrl+c有乱码信息出现.
这是乱码的截图
这是整个路由的启动信息:
