WIZnet的芯片能提供六种不同的网络状态。

这里有六种不同的LED灯：

1) LINKLED: Link LED / Active low in link state indicates a good status for 10/100M. It is always ON when the link is OK and it flashes while in a TX or RX state

2) SPDLED: Link speed LED / Active low indicates the link speed is 100Mbps

3) FDXLED: Full duplex LED / Active low indicates the status of full-duplex mode.

4) COLLED: Collision LED / Active low indicates the presence of collision activity.

5) RXLED: Receive activity LED / Active low indicates the presence of receiving activity.

6) TXLED: Transmit Activity LED/ Active low indicates the presence of transmitting activity.

一般而言，这个黄色和绿色的发光二极管在RJ45里是被接驳到全双发光讯号和这个已连接的发光讯号。在接收和传送的时后，这个LINK指示灯会在闪。如果你想在传送中及接收中的发光二极管里分隔出这个LINK指示灯讯号，以下电路图应该要使用。

希望你喜欢^ ^ .
