Hi all,
I wanted to check traffic between two pc's. I have 100 megabit ethernet.
I cut a original cable (cross over) and reconnected
tx+ and rx+
tx- and rx-
rx+ and tx+
rx- and tx-
The cable works fine. Between the open pins of the cable I put a LED incl. a
resistor to "see" the bits.
But there is no light during traffic.
I used a LED where I can see the light from 1 milliampere. So I thougt the
load is low enought.
I expected a voltage between the pins lower than 12 volt. Thats why the led
got a 4 kiloohm resistor.
The traffic is not disturbed by the LED.
Any suggestions?
