yeah, that's the question, what pins out of the 8 pin RJ45 are required??

After punching down all 8 wires to a female RJ45 jack, and removing them one at a time, and trying to reconnect, I have determined that only 5 of the 8 pins are needed. What these 5 pins are, tx rx, etc, I don't know.

DB9 &nbsp &nbsp RJ45

1 &nbsp &nbsp &nbsp 1 = un-used

2 &nbsp &nbsp &nbsp 2 = NEED

3 &nbsp &nbsp &nbsp 3 = NEED

4 &nbsp &nbsp &nbsp 4 = NEED

5 &nbsp &nbsp &nbsp 5 = NEED

6 &nbsp &nbsp &nbsp 6 = un-used

7 &nbsp &nbsp &nbsp 7 = un-used

8 &nbsp &nbsp &nbsp 8 = NEED


Since my 9 pin cables have only 5 conductors, and one is the outside ground on the DB9, I can't use these cables. frown

Oh well, now we know.

Thanks,
