Appendix C. 10 Base-T Cabling
The cable that runs from the computer to the NL100/105 should be a Category
5 twisted pair cable. If the NL100/105 will be connected directly to the
computer, a crossover cable should be used. If the NL100/105 will be
connected to the computer through a hub, a straight through cable should be
used. The pin-outs for each of these cables is shown below.
