RJ-45 pinout from differential board to receiver board.
« on: December 18, 2016, 08:24:23 AM »

I tried couple of off-the-shelf data cables i had, did not work. Need to crimp some new ones.


Wanted to confirm what is the pin-out pattern from the differential board to the receiver board.


Is it :
straight-through? 1,2,3,4,5,6,7,8 --> 1,2,3,4,5,6,7,8
roll-over? 1,2,3,4,5,6,7,8 --> 8,7,6,5,4,3,2,1
cross-over? 1,2,3,4,5,6,7,8 --> 3,6,1,4,5,2,8

I've been using standard cat5 568B wired cables without issue.  I'm assuming that I have split pairs then?   

I had one cable with a bad crimp and I got lots of random data.  I guess that is a sign of picking up noise from another pair.  Actually, the crimp was fine, the EZ connector was missing a pin.
