The pinouts for an Ethernet 10BaseT crossover cable are as follows:

Connector 1 Pinout	Connector 2 Pinout
1	3
2	6
3	1
4	OPEN
5	OPEN
6	2
7	OPEN
8	OPEN

So pin 1 -> pin 3, pin 2 -> pin 6, pin 3 -> pin 1, and pin 6 -> pin 2. All of the other pins are left open.

These instructions can also be used to purchase an Ethernet crossover cable to network your computer and printer together. Don't just buy any RJ-45 cable; the internal pinout for a crossover cable is different from the pinout of an RJ-45 cable normally used in Ethernet. Make sure the packaging is clearly labeled "crossover cable", or have someone create the cable for you.

These cables can be purchased from the following mail order sources. The pricing and part #'s and phone #'s listed are subject to change. Please contact each mail order company for current pricing and part #'s.
