How long can an ethernet cable

Post by yackerena » Sun Dec 13, 2009 7:58 am

How long can an ethernet cable be before a 5 volt output voltage drops below 1.8 volts? I think the parallel port on a PC can detect a voltage above 1.8 volts. If you connect a 5v output pin through a length of ethernet cable, through a switch then back to an input pin, how long can the ethernet cable be before the computer fails to detect the pushed button?

Electrically it depends on the load.
I see you have posted an Ethernet cable question concerning your PS3 pn the Proton Forum.
Is this really a SF or PIC related (or even electronics related) question?
