刚查了RJ45接口的标准如下: 1 TX+ Tranceive Data+ (发信号+) 2 TX- Tranceive Data- (发信号-) 3 RX+ Receive Data+ (收信号+) 4 n/c Not connected (空脚) 5 n/c Not connected (空脚) 6 RX- Receive Data- (收信号-) 7 n/c Not connected (空脚) 8 n/c Not connected (空脚)
请问 TX+ Tranceive Data+ (发信号+) 的方向是指进来的,还是指出去的?
也就是说TX+ Tranceive Data+ (发信号+) 是接板上网卡芯片的RX+,还是TX+ ?? |
