Can I hook my TINI up directly to the 10BaseT port on my PC, or do I have to go through a hub?
Yes, you can hook your TINI directly to a PC without using a hub, as long as you have a 10BaseT-capable Ethernet card installed in your PC. But you must use a special type of 10BaseT cable known as a crossover cable. A crossover cable has the transmit and receive lines crossed internally so that the transmit pins on one end are connected to the receive pins on the other.The pinouts of both a crossover cable and a "normal", or straight-through, cable are as follows:
Crossover Normal Signal Pin Pin Pin Pin TX+ 1 3 1 1 TX- 2 6 2 2 RX+ 3 1 3 3 NC 4 4 4 4 NC 5 5 5 5 RX- 6 2 6 6 NC 7 7 7 7 NC 8 8 8 8where NC stands for "Not Connected". Pin 1 is on the right hand side of the RJ-45 plug if you look at the end of the cable with the latch pointing down. Likewise, Pin 1 is on the left hand side of the RJ-45 jack if you look into the jack with the notch on the bottom.
It's always a good idea to verify that you are using the correct type of cable. You can do this visually (most 10BaseT cables have color-coded strands which can be seen through the clear plastic of the plug) or electrically, by mesuring resistance.
