I've been going through the documentation and have found out how the 68pin octal cable is pinned out to rj45's, but I can't find how the actual ports are numbered from the rj45 straight through dongles. I've included a link to the diagram. My device has ports lit up from the bottom-left 68pin octal cable but I don't know which of the 8 cables is port translates to which LED lit port. Normally we would go to the far end console connection and pull it and find which light goes out, however this isn't an option in this situation.
On the diagram it numbers the ports in an up/down orientation with LED's but the Octal cable's dongle's are arrayed in a left/right orientation. Which gets to the crux of my issue, how do these orientations translate?
This is for a C2611 32 port Async device.
