Hi all

I know TX+ TX- is Transmit & RX+ RX- is Receving.
What exactly does TX+ and TX- means. A small and quick explanation would be fine.

 

You need to specify a context.
What device or communications application is this?

Every signal needs two wires, a signal wire and a return path.
TX+ and TX- refers to complementary signalling. TX+ and TX- are 180-degrees out of phase, i.e. TX- is the opposite (inverted) version of TX+.

The Tx+/- are Complimentary outputs from the Pulse transformer as it's a Centre Tapped one.
