CABLES
10BASE-T/100BASE-TX Pin AssignmentsWith 10BASE-T/100BASE-TX cable, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for receiving data. The “+” and “-” signs in the tables below are used to represent the polarity of the wires that make up each wire pair.

*The “+” and “-” signs are used to represent the polarity of the wires that make up each wire pair.
Straight-Through Wiring
If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover, the two pairs of wires must be straight-through.
