Thanks Mike,
As a terrible customer, I left out a vital bit of information! I want to use a set of V1 RRC boxes, so custom cable is required. I have used the following connections on my custom cable:
DM5AL RJ45 - RRC RJ45
1 2
2 8
3 1
4 3
5 7
6 6
7 5
8 4
This checks out OK with a back to back adapter but not with the RRCs
I wonder what I am doing wrong?
